Insulate Basement Walls: Continuous Layer of Interior Rigid Insulation
If you’re insulating a basement wall on the interior, one of the best approaches is to use a continuous layer of rigid foam. The illustration show the use of R-16 polyisocyanurate. In Climate Zone 3 and most of Zone 4, building codes will accept lower R-values.

Installing Dense-Pack Cellulose
With the reinserted whip pushed to the top plate, the cavity is then filled from the top down with dense-pack cellulose. As the cavity fills, the whip is backed out and withdrawn. Installed correctly, the cellulose is packed tight enough that patching the hole is unnecessary.

A Practical Look at Deep-Energy Retrofits
Cutting a home’s energy use by 50% to 90% is a worthy goal, but the extreme costs keep it out of reach for many. We take a look at the most cost-effective alternatives.

A Look at a Stucco Wall
Stucco is a cementitious mix applied in several layers to a wire-lath base over wood-frame construction or to a masonry surface such as brick, block, or structural tile. Like plaster, stucco is usually applied in three coats: a base coat approximately 3⁄8 in. thick, scored horizontally to help the next coat adhere; a brown coat about 3⁄8 in. thick; and a finish coat (called a dash coat by old-timers) 1⁄8 in. thick. For repair work and masonry-substrate work, two-coat stucco is common.

Roof Insulation Needs Planning
Insulation above the exterior walls should be at least as deep as the code requires for the rest of the attic, which means raising the roof deck higher than conventional trusses allow.

Insulation Makes an Impact
In the climate story, insulation is both a hero and a villain. Installed properly, insulation can dramatically reduce the need for heating and cooling, shrinking both on-site fossil-fuel use and power-plant emissions. Well-insulated homes require smaller heating and cooling equipment, making them easier to electrify. But insulation materials, particularly foam boards and spray foams manufactured with HFCs, can be major contributors to a home’s upfront carbon emissions.
