“With regular clear glass the u-value is about .50,” Cutsforth says. “With fourth surface low-e, you spend 15% more than the standard low-e and you get a u-value of .25, which is much more energy efficient for not much more cost.”
“Fourth surface has been a real game changer in the industry,” she says. “It’s like sunglasses for your windows without reducing natural light. It also reduces the UV-transfer that causes fading of floors and furniture.”
How Energy Incentives Work:
“To me what’s so exciting is the market has become smarter and more affordable,” Cutsforth says. “We have all these resources that give financial incentives to homeowners to replace old windows. In 20 years I’ve never seen so many incentives as there are right now.
There are two county energy incentive programs, one through Clark PUD and another through Energy Trust of Oregon for SW Washington residents. Cutsforth says Henderson & Daughter is authorized to work with either of these local programs.
“Both programs are very easy, no complicated rebates,” she says. “We fill out the forms and submit the proof of purchase and do the work. Homeowners just receive a check. We make it easy.” Just how much of money can a homeowner expect to receive from using these local energy incentive programs? Cutsforth gives the example of one 6×4 window. “At $4 per square foot, the rebate will be $96 dollars,” she says. “For eight windows and a sliding door, the credit can be up to around $1,000.”
