What Our Customers Say
★★★★★
“Once making a decision to insulate my garage after putting in a home gym I was actually shocked at the amount of options and price variances between products. I’m glad I took the time to do my research and was able to find ThermaDoor. I can honestly say it was the only product on the market that I felt was actually going to perform to the highest possible standard. There’s no point putting insulation in the panels that don’t work effectively. I used the premium product, and I think it was worth the extra spend it also has an excellent laminate finish which is easy to clean and foil backing. I certainly appreciate the owner’s willingness to give me advice about the product and insulation which I chose to DIY. It felt like a consultation based on data and not a sales pitch, but it was very interesting to hear about some of the traps of cheap products who actually will have a significantly inferior performance. Thanks again these panels really finish off my new home gym.”
