R-10 Insulation

Sealed Design

Solid non-louvered construction with insulation eliminates air infiltration, creating a complete thermal and moisture barrier for conditioned crawl spaces.

I installed a louvred access door that will accept the styrofoam insert as well, so I can switch between ventilation and insulation seasonally if I so choose. Installation was simple and the components were well designed and sturdy.

Great solution for insulating my access to crawl space.
Doors were well packed for shipping, but somehow arrived with damage to door. I reached out to support and their response was rapid. In a few days I had replacement of damaged parts. Excellent solution and customer service!
