When is the Upgrade to WMP-50 Facing Worth the Extra Expense?

    Posted in Blog        

The facing materials that serve as vapor retarders and barriers for your fiberglass insulation are key components to the structure of your metal building. But there’s always a dilemma when choosing the correct facing for your insulation needs—in this case, when is the upgrade from a WMP-VR to a WMP-50 worth the extra cost?

Before we answer this question, it is important that you first understand what both products offer.

WMP-VR

WMP-VR is the most popular (and basic) form of protective facing. For its low price, it is an incredible quality and standard duty product. It has received good ratings from nearly all types of industries, including agriculture, manufacturing/industrial, and warehouse buildings but is most excellent for chemically-hostile environments. WMP-VR is suitable for most applications and is durable with moderate abuse when used for roof installation.

Because of its low expense and high quality, WMP-VR is a favorite among contractors and is suitable for the majority of basic roof-mounted applications. Its cost and quality are two can’t-beat factors for those looking to choose budget-friendly options that are also good long-term investments.

WMP-50

WMP-50 is a good choice for extra durability and maximum abuse resistance in comparison to WMP-VR. Its added cost per square foot is linked to its superior perm rating, strength, and longevity compared to other facings. WMP-50 can be used for wall installations and is built for high abuse resistance.

And a good thing to note is the foil-esque layer on most WMP-50s is not actually foil, so unlike what some people claim, it doesn’t serve or have any added benefits of being a radiant barrier.

Because of its higher cost per square foot, it is not the most popular facing on the market, but its increased perm rating and durability ratings make the extra cost well worth it. For highly abused environments, it will give you a better lifetime investment than a standard WMP-VR installation.

When Should I Upgrade?

The upgrade to WMP-50 is certainly worth the extra cost when you need the extra durability and strength. In comparison to WMP-VR, WMP-50 has a higher rating for resistance and abuse for all types of building structures. Most buildings don’t need the extra resistance or durability in the roof area because they’ll never be exposed to such abusive conditions. We recommend you consider WMP-50 if you’re looking for a solid facing for any exposed wall surface, especially when an interior liner panel is not used.

At the end of the day, the upgrade should be made only when the longevity of your insulation is at risk. WMP-VR facing is the most popular product on the market because it is sufficient for the majority of building insulation and resistance needs. But if your metal building is in an environment that requires greater tensile strength, and better perm ratings, consider making the upgrade to the stronger and more durable WMP-50 facing for a greater lifespan and overall investment.

Long Tab Banded System vs. Simple Saver Liner System

    Posted in Blog        

When you’re in the market for filled cavity insulation assemblies, there are two main systems you need to know: Long Tab Banded and Simple Saver Liner.

But in order to know which is right for you, you’ve got to weigh the pros and cons of each. Once you understand their differences, you can decide the best-fit system for your metal building.

Long Tab Banded System

This is often explained as a filled cavity system. It uses laminated insulation that’s parallel to the purlins with long facing tabs that have to be held to the tops of the purlins, which suspends the insulation into the cavity between the purlins, leaving the purlins exposed.

Pros

  • Cost-effective
  • High R-Value
  • Meets specified U-Values defined in current energy codes and standards
  • Easier access to purlins for HVAC, electrical and maintenance services, reducing the number of penetrations in vapor barrier.
  • Provides mechanical support from underneath
  • Much more efficient that the old ‘Sag and Bag’ technique
  • Long-lasting
  • Class A fire safety rating
  • Installation is not as technical as a Simple Saver Liner System

Cons

  • Does not provide fall protection.

Simple Saver Liner System

This is typically a little more expensive than the Long Tab Banded System. It is a fabric liner system that provides Osha approved fall protection and isolates the purlins from the inside air.

Pros

  • Strong and durable for longevity
  • Osha approved fall protection
  • Bright white fabric liner and concealed purlins increase light reflectivity, saving money on lighting equipment
  • Helps prevent condensation
  • Minimizes insulation compression, while still assuring fundamental performance
  • Provides low U-Values for energy code compliance
  • Class A fire safety rating

Cons

  • Harder access to purlins for HVAC, electrical and maintenance services
  • Installation is fairly complex. Qualified installers are recommended.
  • Not as budget friendly as a Long Tab Banded System.

It’s important for you to understand each system’s differences, so that when the time comes you choose the right system for your building. Remember, the folks at CMI are here to help you determine the best system for your unique application. Just drop us a line!

5 Things to Know about Adding Insulation to a Metal Building

    Posted in Blog        

Insulation is key to keeping your metal building’s interior comfortable, making your building more energy efficient, controlling moisture intake and muting noises.

Before you begin adding insulation to your metal building, here are five things to keep in mind.

1. Install a radiant barrier.

A radiant barrier is placed between your building’s metal exterior and the insulation, helping mitigate heat transfer. Installing one will help reduce the heat transfer in both directions, also helping decrease condensation that can lead to rust and corrosion of your metal building. There are two kinds of radiant barriers: perforated and nonperforated. The kind you use depends on what the temperature and humidity levels are where your building is located.

2. Determine your location’s R-Value.

The R-Value of insulation signifies its ability to resist heat transfer. The higher the R-Value, the higher the resistance level to letting hot air escape your building and cold air enter it during the cold months and the opposite effect during the warmer months. Each type of insulation will have its own R-Value, so determining what you need based on the goals of your insulation and your building’s location is necessary before purchasing the insulation.

3. Address appropriate ventilation.

Addressing appropriate ventilation is a necessary step to achieving good indoor air quality and protecting whatever is inside your metal building. The building itself needs to breathe, so the insulation you select, how it’s applied and how you plan on using your building will impact the airflow and the need for less or more ventilation.

4. Choose fire-rated insulation.

Most likely your metal building is going to be used for some type of work-related activity. And in these cases, you want insulation that’s fire resistant. No one wants to ever think about something of theirs catching on fire, but it is a possibility, so you can have some peace in knowing that your insulation won’t aid in a fire spreading if one occurs. There are several fire-rated insulation types on the market, so just review the advantages and disadvantage of each before choosing one.

5. Select the right type of insulation.

Once you’ve done each of the abovementioned things, you can select the right type of insulation for your building. The following types of insulation are the ones most commonly used, either alone or some type of combination, for metal buildings.

Batt and blanket insulation

This is typically installed in roofs and walls. It’s made up of mineral wool or fiberglass, and because it has a tendency to gap, bunch or shift during strong winds, which then makes it useless, it’s best to let a professional install batt and blanket insulation.

Loose-fill insulation

Appreciated by “green” enthusiasts because some kinds are made from recycled materials, loose-fill insulation provides a good amount of coverage for floors, walls and attics because it’s capable of filling odd shapes. It’s blown into crevices and tightly fills each space to prevent air leaks. Besides recycled materials, this insulation type is also comprised of pellets made from rock wool and fiberglass.

Spray foam insulation

Spray foam is one of the most expensive insulation options, but it’s also a very effective one. It’s sprayed directly into the area you need insulated, providing a strong barrier and a high R-Value. Spray foam consists of a liquid that encompasses a foaming agent, and once it’s sprayed it expands and turns into a solid, airtight plastic.

Rigid board insulation

Rigid board insulation comes in a stiff board and can be cut to your desired thickness. It’s made from fiberglass, polystyrene or polyurethane and most used on roofs and concrete slab edges or if your building is more at risk of fire. It’s a fairly easy route to go if you plan to install it yourself.

Choosing The Right Insulation System For Prefabricated Metal Buildings and Pole Barns

    Posted in Blog        

Insulation is needed in all metal buildings. When the right kind of insulation is used and when it’s installed correctly, it’s nothing but beneficial to the owner of that building.

Prefabricated metal buildings and pole barns especially need insulation added. These types of buildings are manufactured in patterned parts or sections beforehand and made for quick assembly. Because these buildings are constructed to be built as fast as possible, there can sometimes be problems if the right insulation isn’t used or installed properly or if it’s not installed at all.

Building owners can see problems with heat escaping through purlins in the winter and then heat entering through the purlins in the summer. Some prefabricated metal buildings use certain insulation and installation methods that compress the insulation, which usually leads to condensation and a shortened roof life. No metal building owner wants to have any of these issues.

CMI can help metal building owners steer clear of these problems with their Retrofit insulation system. This system is simple to use, requiring only one person to install the insulation instead of a whole crew, which saves you money on labor. CMI uses formaldehyde free fiberglass insulation that’s laminated with a smooth, heavy-duty facing. The insulation is rolled up and then rolled out between the purlins where only one person is needed to securely fasten the purlin clips, which keeps the insulation in place. This Retrofit system is easy to install and easy on your wallet.

Adding insulation to your metal building or pole barn is the best thing you can do for your building and for yourself. It’s going to save you money in energy costs, prevent condensation in your metal building and give you a more comfortable work environment that will increase productivity. Choosing CMI and their Retrofit system is the best choice you can make for your prefabricated metal building or pole barn.

Insulation Systems That Provide OSHA Fall Protection For Metal Building Erectors

    Posted in Blog        

Falls are one of the most common causes of work-related injuries and death. According to the Occupational Safety and Health Administration, falls are the leading cause of fatalities in the construction industry.

OSHA is a federal agency whose job is enforcing safety and health legislation. To comply with the laws OSHA enforces, CMI offers two insulation systems that provide OSHA fall protection for metal building erectors.

Simple Saver is a system for roofs and walls that provides low U-values and emissivity levels. This system is OSHA Compliant and a patented fall arrest system that’s made to be durable for job site safety. The Simple Saver roof liner system supports the insulation permanently, withstands the severities during the installation process and provides individuals working below with protection from falling objects. All of this limits the liability of contractors, designers and owners.

Our other system is Sky-Web II. This is a fall protection and insulation support system. It’s a weightless, economical mesh system that provides fall protection during construction and keeps working as an insulation support system even after the job is completed. This roofing system is basically an invisible support system that CMI custom makes to fit the building it’s going to. We also ship it with all of the required hardware to ensure a quick, simple installation.

CMI cares about its customers and their safety, which is why we offer insulation systems that provide OSHA fall protection. Contact us today to learn more about these insulation systems or to see how we can help you out with your insulation needs.

Everything You Need To Know About The 2012 IECC Commercial Energy Code

    Posted in Blog        

Every three years the International Code Council releases a revised version of the International Energy Conservation Code. The latest energy code was given in 2012, and some feel that this one is stricter for metal buildings, at least in certain categories, than the one from 2009.

Although the ICC released this code two years ago, only a small handful of states have adopted it so far. Below is a list of those states:

  • Effective Statewide
    • Illinois
    • Maryland
    • Massachusetts
    • Rhode Island
    • Utah
    • Washington
  • Statewide Adoptions With Limitations
    • Colorado
    • Missouri
    • North Dakota

The basic overview is that the 2012 code requires more insulation, better windows, more efficient lighting, and a tighter envelope and ducts. There are specific requirements for metal buildings, and requirements vary according to the climate zone you’re in. The U.S. Department of Energy has divided the U.S. and its territories up into eight climate zones.

When it comes to insulation, identification must be clearly marked. The insulating materials have to be installed so that the manufacturer’s R-value is noticeably visible upon inspection. The manufacturer has to put an R-value identification mark on each piece of building thermal envelope insulation whose width is 12 in. or greater.

As for a metal building’s roof R-value, R-5 thermal blocks are required or the U-factor Compliance Method must be used. Two layers of insulation are also mandatory. Another interesting note about R-values is that they have increased for most climate zones in relation to above-grade walls, ceilings, basement walls and crawl spaces. Specifically with wall insulation, the requirements for climate zones 3, 4, 6, 7 and 8 are now more stringent, and for the first time, builders in zones 6, 7 and 8 are required to install exterior rigid foam insulation or use another similar wall insulation strategy. The listed code requirements for R-values are only the minimum requirements.

No matter what climate zone you’re in, if you use heated slabs, insulation is required along with them. All climate zones also require builders to perform duct tightness testing and a blower-door test. Additionally, they must comply with two checklist requirements for better air tightness in their buildings.

To know if your insulation package is going to pass the 2012 code requirements, there are a few things to check. First, look and see if your state has even adopted the new code. If it has, then find out what climate zone you’re in. Once you know those two things, then you can look up the minimum requirements for insulation R-values and the installation process.

If you need help making sure your metal building and its insulation package meets the code requirements, CMI is the company to use. We offer free COMcheck certification for all metal buildings, and we also structure our insulation systems so that each passes the energy code requirements.

Perforated Vinyl Vapor Barrier For Residential Basement Wall Applications

    Posted in Blog        

Basements are known to be one of the coldest areas of a house. They account for about 20 percent of a home’s total heat loss. Many residential basements are concrete, concrete block or stone, which have very little insulating value and are why basements are cooler than other rooms.

Because basements are cooler areas, they tend to attract moisture more. Various problems occur because of moisture buildup through your basement walls, including damage to your home and health issues for those living there.

This is why you need good insulation that’s installed properly. CMI recommends using fiberglass insulation for residential basements. Their insulations are usually installed with a facing material that’s laminated to the surfaces, and this facing provides vapor retarder protection and defends insulation from condensation.

Properly installed insulation and vapor barriers prevent many problems that can happen and affect your home and anyone inside. Vapor barriers keep moisture from condensating against the exterior wall surfaces

The effectiveness of vapor barriers depends primarily on three factors: location within the insulated selection, permeance and proper installation. Vinyl facing material has a 1.0 permeance rating. Materials with a 1.0 perm rating or lower are considered sufficient vapor retarders

CMI can also provide perforated vapor barrier facings.  Obviously, perforating the vapor barrier seams counter intuitive.  However, some circumstances are such that perforating the vapor barrier helps a moisture wicking foundation breathe better without exposing the fiberglass blanket to the interior of a living space.

When you use CMI’s insulation with perforated vinyl vapor barriers, you prevent moisture from being trapped between your basement wall foundation and the insulation, avoid certain health issues that occur from moisture buildup and save money on heating bills. All of these reasons are why you should choose CMI for your residential basement insulation needs.

Free COMcheck Certification for Metal Building Envelope

    Posted in Blog        

Metal buildings are everywhere, and that’s because they serve so many purposes. They can be used for commercial, industrial, recreational and institutional purposes to name a few. In fact, metal buildings consist of more than 40 percent of the low-rise nonresidential construction category.

CMI specializes in insulating metal buildings. Not only do we provide the best insulation for our clients, we also offer free COMcheck certification assistance for metal building envelope.

COMcheck, which stands for commercial check, is the energy code compliance software provided by the United States Department of Energy to assist contractors in becoming compliant to current energy codes.  Local building inspectors typically require a COMcheck compliance certificate before allowing occupancy in a building.  If your building complies with the building energy laws and codes for your state, as well as the IECC and ASHRAE, then you receive our certification.

Fiberglass insulation is a cost-effective and energy-efficient envelope material for metal buildings. It is also a very popular material to use because this type of insulation is designed specifically for metal buildings.

COMcheck requirements vary depending on the purpose of the building and the climate zone where the building will be built. Considering the variety of building components and insulation systems available for metal buildings, not just any insulation system will pass energy code requirements. CMI helps owners and contractors put together insulation systems that will pass energy code requirements in accord with the COMcheck software available through the department of energy.

CMI does this certification for anyone constructing a metal building, and we make sure to always stay aware of new regulations and any energy code changes so that we provide an effective inspection and service for you.

If you’re looking for a company that’s superior in the insulation business and that specializes in working with metal buildings, contact CMI today for more information on how we can help you with your insulation job or receive a free COMcheck certification.

Benefits of Investing In Our Skyrail System

    Posted in Blog        

skyrail systemIf you’re someone who has a roofing repair or construction project on a minimally sloped roof, then you should be using CMI’s Skyrail system.

This system helps for whatever your roofing project might be and is more beneficial toward your project than any other method out there.

First off, this roof sheet moving system improves roof sheet productivity. Normal roof repair and construction requires a lot of time to move equipment along the roofline. Typically construction crews rely on manpower to keep the materials distributed to the leading edge instead of having them work on installing the roof with the rest of the crew. This makes the roofing project take longer than necessary. With the Skyrail system, these crews no longer have to waste time and manpower on people carrying and distributing roof sheets themselves because they now have a set of trolleys and rails that holds the materials and moves with them along the roof.  Each trolley is capable of holding up to 1,000 lbs. of materials.

It’s also an easy to use and cost-effective option. Don’t think you’re wasting your money in purchasing this system because it will almost pay for itself in labor savings within the first few uses. The Skyrail roof sheet moving system, will cut any installation time in half.

Here at CMI, we put the customer’s needs first, which is why our products are made to benefit each and every one of our customers and their projects. Contact us today to see how our Skyrail system can help with your roofing project or to receive your free quote.

Why Do We Take the Time To Pre-Cut and Individually Roll Each Piece of Insulation?

    Posted in Blog        

At CMI Insulation, our motto is “Always imagining we’re the customer.” Everything we do is based on imagining we are the customer so we can provide the best products and service. This is one reason why CMI is the only place to buy insulation systems for your metal buildings and pole barns.

We know the importance of your insulation needs, which is why we pre-cut and individually roll each piece of our insulation. We provide these services because it’s beneficial to you, the customer, and considerably better than the alternative option

Other companies that don’t offer these services make you go the route of field cutting. This process requires an installation team to cut your product on site. Field cutting increases installation labor time and costs, and it’s also wasteful and messier.

When your insulation rolls aren’t pre-cut and individually wrapped, your installation process ends up taking more time and costing you more money. The installation team has to cut each roll to make it fit for you on the spot before they begin installing, requiring them to do more work that then forces you to pay them more.

An additional reason we pre-cut and individually roll our insulation for our customers is so you don’t have to deal with a messier situation than necessary. Most construction sites are a dirty, muddy mess, which means your new white facing will become dull and unappealing when it has to be cut on site. You also don’t have to deal with all the leftover waste of the unused insulation with us.

At CMI Insulation, we provide the best service and products to save you time and money, which is why we take the time to pre-cut and individually roll each piece of insulation for each customer.
