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.

Will Fiberglass Insulation Lose R-value When It’s Compressed During Installation?

    Posted in Blog        

Fiberglass insulation, when properly installed, doesn’t move or settle so it maintains its R-value and does so for a long time. But when fiberglass insulation is compressed during installation, it loses its R-value.

R-value is important because it’s what insulation is identified and labeled by. If you have a 2×4 wall, then you buy insulation that’s listed for a 2×4 wall. If you buy insulation that’s listed for a 2×6 wall, then you’d have to cram it into your 2×4 wall. This may not seem like a big problem, but it is.

Fiberglass insulation needs some airflow in order to work correctly. Tiny air pockets inside the insulation basically trap air between the fibers and are what make the fiberglass insulation R-value effective. Compressing fiberglass insulation is counterproductive. It means you’re squeezing all the air out of it, and it needs that air in order to work how it’s made to work.

Something else you have to watch out for are gaps and holes. If there are any gaps or holes due to compression, then it’ll lose R-value. Let’s say you have a 5 percent insulation gap. That doesn’t seem so bad, right? Well actually it is because it means you can have up to a 25 percent drop in your R-value.

Here are the main issues with buying fiberglass insulation and then compressing it: you’re going to be paying more money and putting in more work but not receiving a greater benefit, and if you compress it too tightly then you can damage the area you’re using it for. None of which you want to deal with.

In order to make sure you’re getting the full R-value during pre-
installation and post-installation, you need to buy the correct size, make sure there are no gaps or holes and under no circumstances compress the fiberglass insulation. Do these things and you’ll receive the benefits guaranteed by your fiberglass insulation and its R-value.

What Is The Cheapest Way To Insulate A Pole Barn?

Insulation is all about regulating the temperature inside the pole barn. To know what type of insulation you will need, you have to look at your location and what the purpose of your barn is.

If you are in the lower half of the United States, you might be more concerned with keeping heat and moisture out so that equipment won’t rust. In the upper States, the goal will be to keep heat in so that equipment and people can use the barn.

There are various ways to insulate your pole barn. Many people will consider fiberglass insulation since it’s already being used quite often. This insulation is a man-made and is easy and quick to install. It is easy to cut, but making any adjustments with cuts or compressing will make it less effective and provide little resistance to the airflow. Fiberglass can cost up to $1 per square foot depending on the R-value and the thermal resistance one is looking for.

Another option is to use spray foam insulation. The cost of this insulation is much higher than traditional insulation. The installation of spray foam is also more expensive than other insulators because of the chemicals involved as well as the problems associated with a poor installation (which can bring the entire barn down. While the cost of spray foam insulation will vary, it can cost up to $2 per square foot, one inch thick.

Foil insulation or reflective insulation is another type of insulation that is cost-effective. The goal of this insulation is as the name says to reflect the heat away. The aluminum foil is usually attached to some material or there will be two layers of foil with foam or plastic bubbles in the middle. This insulation will reduce heat flow. This type of insulation is great in the summer, but in extreme cold conditions needs to be paired with other insulation.

The choice of insulation is dependent on your locale and the weather conditions that will exist. Make sure to obtain quotes from local vendors and compare insulations to find the best deal for what you need.
