Home Heat Efficiency: Six Tips
Primarily a two-person job, the work involves punching holes at the bottom and top of each stud bay and filling up the space with densely packed insulation. You can rent a blower, and you can purchase bags of insulation at large hardware stores. The difference insulation can make, Silva says, is astounding.”It was five or six at night, and we started at one corner of my house in the living room, and I worked across the back of the house, which was the living room, dining room, and kitchen wall,” he recalls. “My wife was inside the house, and as we were blowing each bay of the wall, she could actually feel the difference.”
6. Old Windows
If you’re intent on sticking it out with your old single-pane windows, make sure the glazing is intact. If it’s cracked, repair it. And be sure your windows are locked. “I don’t know how many times I’ve gone into a place where the owner has complained about a draft, and I’ve gone and locked the windows,” Silva notes. “It can make a big difference.”
So can insulating the cavities of your windows. High fuel cost doesn’t mean that you have to retire a home’s old rope-and-pulley windows, Silva explains. Instead, take the interior window trim off and pack the cavity, as well as the top and bottom of the window, with strips of rigid foam insulation.
Next, fill any voids with expanding foam insulation. Finally, in place of the rope-and-pulley, attach a spring balancer where the pulley is and hook it onto the bottom of the window. The result: Old World windows, New Age efficiency.
