Download and print the insulation rebate checklist (PDF).Get the Checklist Common ScenariosAttic insulation must be placed between rafters (air circulation above) or fill the entire exterior ceiling cavity. Walls must be exterior facing walls. If the home has a heated basement, only the exterior basement walls will qualify. If the home has an unheated basement, it may qualify for an insulation rebate on either the exterior basement walls or the floor (between heated and unheated level), but not both. Crawl spaces may qualify for either the foundation wall insulation or underfloor insulation, but not both. Frequently Asked Questions About Insulation Expand all What is R-value? R-value is a measure of insulation's ability to resist heat traveling through it. The higher the R-Value, the better the insulation works to keep your home warm in winter and cool in summer. How do I measure my existing insulation's R-value? Assume about R-3 per inch of insulation. If you have some existing insulation in your space, it's relatively simple to calculate the R-value of what's there with the following steps: Use a ruler or yard stick to measure the depth in inches (take a photo!). Find the type of insulation you have currently in the table below and note the factor number listed next to it. Multiple the depth of your current insulation by the factor to calculate the current R-value. Common Insulation Types Type Description Factor Batts Fiberglass Rolls Lightweight yellow, pink, or white insulation that looks like sheets of cotton candy. 3.2 Granules Small, pebble-like particles may be vermiculite or perlite. This type may contain asbestos — professional testing and removal may be necessary. 2.7 Paper Fibers Gray, fluffy fibers that resemble shredded newspapers are probably cellulose insulation. 3.7 Dense Fibers Heavy, gray or off-white material — sometimes with black specks — is likely rock wool insulation. 2.8 Loose Fibers Light, fluffy yellow, pink, or white material that isn’t in batt form is likely loose-fill fiberglass. 2.5 What if I'm adding insulation under my house? Crawlspace, or underfloor insulation, is counted as floor insulation and would pay the Chelan PUD floor insulation rate. Eligibility is based on the average existing insulation depth at the thermal boundary. The square footage is multiplied using the length and width of the crawl space floor. Foundation wall insulation is counted as wall insulation and would pay the Chelan PUD wall rate. Square footage is calculated by taking the foundation wall perimeter length (all perimeter walls) and multiplying by the foundation wall height. What if I'm adding insulation to my basement? If your basement is heated, only the exterior basement walls may qualify for rebates at the wall rate. Square footage is calculated by taking the wall perimeter length and multiplying the wall height. If the basement is unheated, the space may qualify for either the exterior basement walls or under floor, but not both. Rebate ApplicationIt's time to prepare your rebate application materials!
