Lessco Air-Vapor Barrier Box
by Thermal Associates

(Electrical supply houses should see the bottom of this page for free offer.)

We are happy to present the LESSCO Air-Vapor Barrier Box.  You are here because you want the most energy efficient and comfortable house possible.  If you are not using the LESSCO Air-Vapor Barrier Box with all your electrical boxes, then that is not going to happen.

Cold air infiltration/warm air ex-filtration occurs through electrical boxes in exterior walls and in ceilings.  This leakage creates higher heat loads and warm air ex-filtration also carries water vapor that condenses in the walls or attic cavities creating rotting action and mold growth!

The LESSCO Air-Vapor Barrier Box, properly installed, can eliminate the leaks and provide you with an energy efficient, healthy and more comfortable home.

The new, improved LESSCO Air-Vapor Box has incorporated a unique "hinge" feature. The new design makes virtually all current electrical boxes compatible with the new  and improved LESSCO Air-Vapor Barrier Box.  It has a large interior work area:  6-1/2 x 7-1/2 x 2-7/8 for easy installation with up to 3 gang capacity. See the installation information here. Developed by an American home-builder for the American home-building market!

If you have an electrical supply house or other means for sales of the Lessco boxes we would be happy to send you a free sample while our supplies last. We find that if displayed these boxes can enhance your sales in new home construction. Just email us at sales@thermalassociates.com with your company, name, address, phone# and how you found us we will send one right out.
