Everyone wants their homes to bring in the beauty of the outdoors, but which products are best, and which installation techniques can hurt your performance and potentially create headaches? The Lunsfords debunk the myth of windows and doors causing all drafts, teaching stack effect, and demonstrating the blower door test of their own fully-enclosed home build.

Featuring a visit to the Alpen Window factory in Colorado to meet with high-performance window expert Alison Ray, footage from Bill Spohn’s fascinating high-performance home built entirely in a factory by EcoCraft Homes, sun tubes from 475 High Performance Building Supply, and a rough-in blower door test. You can consult with Corbett long-distance, or find a testing professional near you to pursue excellence in your own home.
