PODCAST: Air-Tight Window Installationcomments (1) July 11th, 2011 in Blogs
Windows represent the biggest potential holes in the building envelope. Think about it: the rough openings are just big holes — until you actually plug the opening with a window.
But plugging the opening with a window unit doesn’t necessarily keep the weather out. Think about an inner tube with a tiny hole in it. If the tube is full of water, it drains slowly. If it is full of air, it goes flat almost immediately.
Air squeezes through tiny holes a lot faster than water does. So sealing a window for air leaks can have a huge effect on the energy performance of a home.
This week we look closely at the Energy Smart Details department from the current Fine Homebuilding magazine (that’s issue 220 for those of you who are keeping score). The window details come from our premium website, Green Building Advisor, and we’ve asked a couple of our advisors to weigh in on the topic.
