Insulation for Alaska and Hawaii Builds
Alaska homes need high insulation levels and careful vapor and air control to stay warm and avoid condensation inside walls. Hawaii homes need insulation mainly to keep heat out, especially in the attic. Impacco supplies Knauf Insulation and Owens Corning products and ships them in protected, compressed packaging to save freight space.

- Insulated foundations and floors over crawl spaces
Hawaii: Keeping Heat Out
- Attic and roof insulation to cut heat gain
- Ventilation to remove hot, humid air
