Thermaguard Reflective Insulation

Thermaguard Reflective Insulation

Reflective foam insulation that blocks 97% of radiant heat.

97% radiant heat blocked 750 sq ft coverage 6'2" x 125' roll

Thermaguard Reflective Insulation is designed to help reduce heat transfer and improve energy efficiency within metal and post-frame buildings. By reflecting radiant heat, it helps maintain more consistent interior temperatures and overall building comfort.

Three millimeters of closed cell foam with aluminized reflective top coating, and very strong woven polypropylene bottom layer. Dutch Tech provides a fundamental innovation in insulation technology. Continuous, durable insulation which shuts out 97% of radiant energy and 22% of convective. To take your building’s thermal efficiency to the next level, ask for Dutch Tech Industries’ Therma Guard Insulation.

Unlike reflective foil and double bubble insulation, this product does not sag and get loose edges. It is many times more wind-resistant. Because of the woven polypropylene, it holds nails and staples much better. This results in a much cleaner job that’s quicker and easier for contractors. We understand the struggles of installing weaker products that tend to stretch and/or blow off. ThermaGuard was designed to enhance the installation process with the contractor in mind.

I can’t say enough good things about them. I wanted a hobby shop on a piece of property I bought. I called PAC and the rest was easy. They had great advice and very fair pricing. I live out of state and put my complete trust in the crew. They not only met my expectations but surpassed them. I can’t say enough good things about them. Would highly recommend them.
