Steel Roofing Insulation: 6 Installation Tips
Steel roofing, and its insulation, can be made easier if you follow a few basic installation tips. Steel roofing insulation is commonly found in steel buildings comprised of the basic building components of walls, roof, framing, bracing, and a foundation, which work together to solidify and secure a structure. As steel buildings are specialized compared to other wood or masonry structures, it’s essential that roof insulation be applied correctly. Below are just a few instructions that will help you with this process.
First of all, keep in mind that roof installation rolls are divided into lengths long enough to cover the distance from one eave to the other, and leave a one-foot overhang on either building side. Therefore, make sure you measure the roof accurately so that you can leave this necessary one-foot overhang of material on each side.
2. Use Tape
When you set out to insulate steel roofing, always start at the end of the building you’re insulating, and secure one side of the roll temporarily by connecting the insulation to the eave strut with some double-faced tape. As you will need a lot of it, make certain you have extra rolls of double-faced tape before you install steel roofing insulation. This is one of the handiest tools to keep in your toolbox.
3. Block Vapor
Another good practice is to pull the insulation over the purlins with vapor barrier in the direction of the metal building’s interior. In order to maintain tension on your roof roll, apply double-faced tape on each end of the insulation.
4. Stay Consistent
Put in the next roll in the exact same way to make sure the rolls are stretched without slack and also properly aligned and butted closely. If there is any looseness in the application of your insulation, this will decrease the insulation's overall effectiveness.
5. Cover Rips
Keep in mind that any tab tears or rips need to be covered with matching facing tape in order to make certain of a snug vapor seal. As with the tightness in stretching out the insulation, if there are gaps where air can enter and exit, the insulation’s effectiveness will also be compromised.
6. Trim to the Edges
Do not neglect to trim excess insulation flush, which helps prevent if from behaving like a wick and guiding water into the prefabricated metal building. Water buildup is a dangerous factor, so when you install insulation, do everything you can to prevent structural elements that lead to water building up where you don’t want it to be.
Specialized steel buildings clearly require special attention when it comes to installing insulation. And because steel buildings do not hold the heat as well as wood or masonry structures, insulation is extremely important to the overall function of the building. These brief tips may appear to be obvious instructions, but if followed they will make for an effective insulation application.
