Commercial Buildings & Warehouses

Due to overwhelming popularity of using our radiant barrier foil insulation in commercial applications, we designed a specialty product for metal building insulation applications. We also created a secondary website completely dedicated to installing radiant barrier in those type of structures. Please visit (or click on the logo to the right) to see more complete install photos with instructions & videos on how to install radiant barrier foil in metal buildings, sheds, barns, warehouses, garages, airplane hangars, quonset style buildings, shipping containers, red iron PEMB style buildings, etc.

Controlling Heat in Your Building with BlueTex™ Insulation

On a non-conditioned building, there really is nothing better than a radiant barrier to control the heat gain. Structures like sheds, carports and barns can all benefit greatly by adding a layer of radiant barrier near the roof line and any sun-catching walls to keep the heat out. For this reason, traditional insulation is not necessary. If you’re not heating/cooling the building and you’re in a warmer climate, the goal is not to make the structure airtight in order to keep cold (or hot) air inside of it; the building is vented, so it can’t be airtight. Therefore, the most realistic expectations you can have for a building that you are not heating or cooling, is to get it at (or close to), outside air temperature (also known as ambient air temperature).
Getting the air temperature lowered is largely relative to the amount of ventilation you have going through the structure. However, keeping the inside of a metal structure at or near ambient temperature is practically impossible if you do not have a radiant barrier. The radiant barrier will work to reduce the surface temperatures by blocking 97% of the radiant heat, and combined with good ventilation, you can help bring the air temperatures down. You will be amazed at how much cooler the warehouse space below feels. Normally, heat would radiate off the roof and make everything under the roof very hot, regardless of how great the ventilation is. The foil works best in buildings without air condition when it it closest to the outside – acting as the first line of defense between the building and the hot roof.

Controlling Condensation with BlueTex™ Insulation

To manage moisture effectively, it is important to recognize that it’s about the process of construction/insulation, rather than any specific product. Our foil/foam products not only eliminate moisture and condensation issues, but also feature a radiant barrier that reflects radiant heat before it enters the building, thereby keeping the building cooler. Additionally, our BlueTex™ products help retain heat during colder months by creating a new, warmer interior surface within the building. By incorporating BlueTex™ insulation, the interior surface of the building is no longer the cold metal, but rather the warmer surface of the insulation. This, combined with the foil and foam layers, ensures that the new interior surface remains warm and above the dew point temperature, regardless of whether you choose foil or white as your interior surface. As per the basic rule of moisture, if the interior surface temperature is above the dew point, condensation cannot occur.

Repairing Old, Dirty, Torn Insulation with BlueTex™ Insulation

Another popular use for BlueTex™ is as a new interior finish over old, dirty, or torn insulation. This system will create a NEW internal air, vapor and radiant barrier, and it will hide the old, dirty, dripping/wet, and falling down fiberglass insulation.
