FAQs for batt, rolled or reflective insulation install or upgrade projects in Seattle, WA

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
