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.

CMI has a myriad of systems for adding insulation to your metal building, give us a call and we’ll recommend the best system for your application.

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.

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. Contact CMI today to use one of our insulation packages or to take advantage of our free COMcheck certification.

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.

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.

Why Do We Use Johns Manville Formaldehyde Free Insulation?

    Posted in Blog        

Formaldehyde is a colorless gas that has a very distinct smell. It’s most likely used in several products in your house, such as cabinets and furniture. When used with these products, it’s given off as a gas that mixes with the air. This means you’re exposed to it when you breathe and some absorption also happens through your skin.

There are health concerns associated with formaldehyde exposure. Depending on sensitivity and the amount of exposure, people have experienced symptoms like skin irritation, sore throat, nosebleeds and asthma. It can also cause air quality issues like air pollution.

Because of these concerns, CMI uses formaldehyde free insulation for metal buildings and pole barns.

We use Johns Manville because it supports a safer, healthier environment indoors and outdoors, which is what we want for our customers.

Another way formaldehyde free insulation makes your homes and buildings better places to be in is being odor free. This way you and your family can breathe in and smell the difference.

CMI also uses Johns Manville formaldehyde free insulation because it’s better to work with. If formaldehyde is used, microscopic strands of fiberglass become stiff and brittle, and as the fibers move or bend they shatter, which sends those tiny glass fibers into the air causing you to have skin and respiratory sensitivity. So because we don’t use formaldehyde, there’s flexibility in our insulation fibers and you don’t have to deal with the frustration of sneezing from dust or having itchy, irritated skin.

While other insulation companies use formaldehyde to make their blanket insulation, CMI chooses not to. We like working with materials that are good for our customers and us, and that’s why we use Johns Manville formaldehyde free insulation.

What Are The Differences Between Metal Buildings & Pole Barns?

    Posted in Blog        

You need a structure ASAP and you’ve done the research and are now debating between a metal building or a pole barn. Which do you choose? Does it really make a difference?

A pole barn is made with wooden poles that are set into holes in the ground and then connected with beams and braces. Once those are secure, a roof is added. Pole barns are easy do-it-yourself projects that are fairly inexpensive.

Metal buildings, unlike pole barns, require a concrete foundation to anchor the entire structure. Once the foundation is laid, the frame of the structure can be built then adding on the wall sheeting and the roof. Metal is more expensive than the lumber to build a pole barn. Renting equipment to lay the concrete foundation and to build the structure also raises the price of the metal building.

Because metal buildings are made from steel, they don’t run the risk of becoming infested with termites and are less of a fire hazard than a wood pole barn, though it should be noted that any fire would warp the steel. The metal barn is also more durable in inclement weather because of the steel is stronger than wood.

While pole barns may not look sturdy, if constructed correctly and repaired when needed, can withstand the harsh weather conditions. Pole barns usually have trusses near the roof, which can be useful for hanging objects, and keep them off the floor. The truss clips also will reduce the chance that a high wind will take the roof off the building.

The bigger the building, the more likely one would lean towards using steel. A larger building is easier to build out of steel because you can bolt the small pieces together securely. Pole barns require lumber that is precisely measure for the specific dimensions. Both types of buildings will require insulation depending on the locale and weather conditions. Because of size differences, your insulation cost for a metal building will be more than the insulation for a pole barn.

While the materials and the structures may be different, both types of buildings are proven to be durable even in harsh weather conditions.

As the Building Season Slows Here in Utah, Building In California Continues at Full Speed

    Posted in Blog        

welcome to californiaThe state of California is at the top when it comes to manufacturing. In 2011, California manufactured over $220 billion worth of products and goods, which placed them in the leading spot for manufacturing. This being said, it’s no wonder commercial construction in California is booming. That means that builders are busy and need to work with experienced and professional contractors to get the job done right and on time.

How is it that commercial construction is booming in California? Investors are spending money on new ventures and companies. These businesses are churning out the many products the nation’s population uses every day as well as the many products exported across the world. Because of the demand for the California products and goods, new commercial construction continues on through winter—long past when it slows in Utah.

CMI Insulation has that experience and professionalism. Our staff is conscientious of what California builders need and want in a good insulation supplier.

Protecting Your Newly Constructed Building

When investing in a steel building, you look at your projected loss on your initial investment against projected business profitability. Protecting your investment is of great importance as it will help your building last and will reduce overhead expenses. We help businesses in California to protect their investments in the following ways:

  • Protect Against Condensation – If moisture lodges in the insulation of your building, the heat transfer coefficient of your building can increase dramatically. We have the knowledge and experience needed to properly install insulation in the building envelope in order to reduce condensation.
  • Free of Formaldehyde – There is significant evidence supporting the thought that formaldehyde is a volatile carcinogen. Not only that, but it causes other health hazards like fiberglass dust and microscopic slivers. We at CMI prefer to protect our employees and customers and work only with formaldehyde-free insulation.
  • Save Money – There is nothing more costly than paying to fix a mistake when it comes to new construction. Costs can vary from only minor additional costs to extremely expensive overhauls.
