Get answers to common questions about insulation services in Girdwood, Alaska.
For Girdwood's heavy snowfall, high humidity, and extreme cold, creating a continuous air and thermal barrier is critical. We prioritize air sealing and high R-value insulation in attics and walls, often using spray foam for its air-sealing properties or dense-packed cellulose for existing walls. Proper vapor control is also essential to prevent moisture and ice dam issues common in our coastal mountain environment.
The ideal time is during the drier months from late spring through early fall (May to September). This allows for exterior work, like adding exterior rigid foam, without battling snow and ice, and provides better ventilation for interior projects like spray foam. Scheduling well in advance is key, as the short construction season creates high demand for local contractors.
Yes, Girdwood falls under the Municipality of Anchorage building codes, which have strict energy efficiency requirements tailored to Alaska's climate. Furthermore, you may qualify for rebates or incentives through programs like the Alaska Housing Finance Corporation's (AHFC) Home Energy Rebate program, which often requires a certified energy rater and specific insulation levels (R-values) to be met.
Look for contractors with extensive experience in cold-climate and coastal Alaska construction. They should be familiar with local codes, moisture management for our high humidity, and techniques to prevent ice dams. Ask for local references, verify licensing and insurance, and ensure they perform a thorough energy audit or assessment before proposing a solution.
Absolutely. Ice dams are often caused by heat loss melting snow from underneath. The solution involves a combination of air sealing your attic floor, upgrading to R-49 or higher attic insulation (per Alaska recommendations), and ensuring proper roof and soffit ventilation. In Girdwood, we also pay special attention to sealing complex roof lines common in alpine architecture and managing the high moisture load from snow melt and rain.
