- Keep it simple – just get a piece of foil between you and the hot roof. Wood strips, straps, cables, adhesive, magnets… you name it. Whatever it takes to get the foil between you and the roof being heated up by the sun is the only thing standing in your way.
- Pretty is nice but not important. It’s OK if the WareHouseFoil™ is wrinkled, crooked or sags a little bit – it still works!
- A big metal box (i.e. your building) is gonna be HOT in the summer! Installing a radiant barrier is almost like putting the building in the shade, it can make a big impact.
Install Method #1 – Drape Over
When possible, the easiest install method for all metal buildings is to go up and over. If you have some rafters or purlins that are a few inches to a couple feet below the roof, this is a perfect place to run the foil on top. Often, you can run several pieces the full length of the building. This is a great method for the 60″ wide WareHouseFoil™ or you can always tape together two 48″ wide pieces to form an even wider piece (use foil HVAC tape for joining pieces together).
The main thing to remember here is to cover as much as possible. You might have to leave some “gaps” between the strips of WareHouseFoil™. While this will cause there to be some reduction in the overall effectiveness of the radiant barrier, the benefit of covering most of the area is much greater so it’s worth the installation effort.
Install Method #2 – Staple the Foil (Adding Furring Strips)
The honest truth is there is really no easy way to attach radiant barrier to heavy gauge metal.
One option is to attach something to the metal that you can staple the WareHouseFoil™ directly on to. Many of our customers have had good success by cutting 3/8″ thick OSB or Plywood into strips about 1-2″ wide. Then, they attach the wood strips to the metal framing with either with screws or adhesive. (Gorilla glue and C-clamps work great!) Once the wood stripping is up, you can easily use 1/4″ staples and attach the WareHouseFoil™ to the wood, just like you would if the building were a wood-framed metal building.
Follow the guidelines for a normal staple up, overlapping pieces if necessary and leaving gaps around the perimeter.
Install Method #3 – Get Creative: Straps, Cables, Adhesive, & Magnets
As mentioned above, sometimes attaching WareHouseFoil™ to all metal buildings can be a real challenge. Sometimes you just have to get creative. However, the payback is huge in comfort!
Here are some other ideas for attaching radiant barrier foil to metal framing:
STRAPS or CABLES – Think of a guitar string pulled tight on a metal beam. The foil could go between the strap or cable and the metal. WareHouseFoil™ is heavy duty but not real heavy. Secure strapping, wires or cable should work well to easily hold the foil up. Zip ties are also very popular and if you have supports that you can tie to, this option works well and is easy and inexpensive to do.
ADHESIVE – Using an adhesive rated for high temperatures works best in all metal buildings. Brush it on and attach the foil. One downside to adhesives is they can be messy and expensive.
MAGNETS – Yes, magnets work. We have had several customers use magnets to hold up the foil to the metal framing – round magnets, square ones, big and small. One customer got really creative and used a high temperature adhesive, brushed it on the metal, and then used magnets to hold the foil until the adhesive set. he continued doing this until he was done with the whole building.
