Weatherization Project
Green Space Construction partnered with a local energy auditor on this weatherization project in Labadie, Missouri. Our client was paying nearly $800 a month to heat their home in the coldest months of the year. After a blower door test was conducted it was determined that the air leakage was equivalent to a 24×24″ window being open all year. Thermal imaging revealed numerous areas throughout the residence that had insufficient insulation and air leakage.
Green Space caulked and sealed the entire exterior including windows, doors, trim, and roof lines. Performing this exterior sealing is a critical component of any weatherization project. We also caulked the interior at these locations. An open, uninsulated chimney chase was also a culprit of heat loss. To remedy this, we insulated the open chimney chase with fiberglass batts and applied fire-blocking. Also air sealed and dense packed with cellulose were the home’s exterior cantilevered windows.
In the home’s attic, we performed a number of improvements starting with a full air sealing package. We then installed custom fabricated truss insulation and dense-packed the attic knee walls with blown cellulose.
We insulated the attic floor with blown cellulose at R-38, along with building and installing a custom attic fan cover and custom attic hatch.
In this picture to the left you can see the dense packed knee walls with blown insulation. This treatment provides a substantial barrier for summer heat.
Green Space installed a new energy efficient exterior door at the basement, and installed new weatherstripping at several exterior doors that had failing materials.
At the basement foundation walls, we removed drywall and insulated the walls with rigid foam board insulation, along with insulating the bandboards. We air sealed these locations, and installed new drywall.
By installing rigid board and air sealing all penetrations, this home’s conditioned air stays in the living spaces and out of the basement.
At the mechanical room, we insulated the bandboards, installed an air sealing package, and dense packed the exterior walls with blown cellulose.
In this picture, you can see the hot and cold water heater lines that Green Space insulated. In the home’s garage, we insulated and sealed the HVAC ducts exposed to the outside climate.
The home’s electrical panel was situated in an uninsulated exterior wall. Green Space installed spray foam insulation selectively in this space, stopping air infiltration but retaining the integrity of the panel.
Attic windows were stifling the ventilation, creating a very hot attic space. We removed these windows, and installed new gable vents and siding. There was also an improperly installed ridge vent, which was removed and capped with new roofing. In keeping with these ventilation improvements, Green Space installed new bath exhaust fans vented through roof.
