Insulation, Draft Proofing, Windows and Doors

Two ingredients are essential to any energy retrofit: insulate to a very high level (beyond building code) and seal the house well. If you achieve these two goals, you can turn nearly any home into a “near net zero” energy home.

The insulation display at REEP House demonstrates options including blown-in cellulose, rock wool, and polyurethane foam. The online REEP Green Home Planner helps you compare their costs and payback.

Super-Insulated Walls

Our walls are insulated with six inches of polyurethane foam, installed and donated by Reitzel Insulation, giving us an insulation value of R38 – nearly double the building code requirement. Polyurethane foam has a high insulation value per inch and locks out moisture and air movement with ease.

Basement Insulation System

The warm basement at REEP House demonstrates that a stone foundation can be safely and efficiently insulated.

A layer of dimple board along the foundation wall and a drainage system along the indoor perimeter manage any incoming water leaks, while six inches of polyurethane spray foam controls moisture and transforms the basement into a cozy living space. To top it off, we used paperless drywall in the basement which reduces the risk of mould.

Warm Attic

REEP House demonstrates what is called a “warm attic”. A combination polyurethane spray foam on the inside slopes of the roof and polyiso board on the outside of the roof gives us a perfect air seal and a great insulation level.

Our attic provides warm storage space above the master bedroom and gorgeous height in the bathroom and second bedroom.
