This Williamsburg, VA attic has several dormers. As part of air-sealing and insulating the attic space, we needed to install PVs (the gray rectangles you see between the rafters) to ensure that no insulation fell into the soffits and so that proper ventilation can be maintained in the attic. Then we installed an R-38 of Cellulose Insulation.
This homeowner contacted us because their "current insulation [was] over-compressed and not doing its job." This is very common in older homes, insulation settles over time and doesn't help keep your home cool in the summer and warm in the winter. We removed the old ineffective insulation, air sealed the attic, and installed a fresh blanket of blown-in cellulose to help make this home more comfortable year-round.
While it's often hard to see what dense packing between floors or exterior walls looks like, these photos show how our techs access the floor (or wall) cavities to fill them with cellulose insulation. A hole is made to fit the hose and then our technician packs the floor cavity with insulation. when complete, this makes a big difference in heat transference for the room above the garage, keeping it cooler in the summer and warmer in the winter.
The conditioned space shared with these knee walls was sweltering in the summer and freezing in the winter due to sharing a wall with an unconditioned attic space. We installed insulation in the wall cavities and covered it with Tyvec to create an air barrier and better insulate the wall. We also installed insulation on the floor of the space to prevent air loss from the room below.
This homeowner wanted to add insulation to their attic to improve the comfort and energy efficiency of their home. We installed a blanket of blown-in cellulose insulation in the attic. The Cellulose insulation used is 85% recycled material and contains a borate that helps to deter pests.
