What Is Nu-Wool?

Nu-Wool is a cellulose-based insulation made from up to 86% recycled newspaper and treated with a safe, fire-retardant borate blend. It’s applied either as loose-fill (ideal for attics) or as WallSeal spray-applied cellulose (perfect for dense-packed wall cavities in new construction or retrofits).

Frequently Asked Questions

When is a good time to add insulation to my attic?

A good time to add insulation to your attic is when you're experiencing high energy bills, uneven indoor temperatures, or noticing drafts — especially during extreme seasons like summer and winter. It's also ideal to upgrade during home renovations, roof replacements, or if your current insulation is old, damaged, or settling below recommended levels.

How long will it take to have my attic insulation removed and reapplied?

We recommend that our customers expect an attic overhaul to happen between 1-3 days, depending on the size and shape of the attic.

Will cellulose or spray foam make my house too tight?

Cellulose and spray foam insulation, especially when paired with proper air sealing, can significantly reduce air leakage — but they won’t make a home too tight if installed correctly. A well-insulated home still needs controlled ventilation, which can be easily managed with systems like bath fans or energy recovery ventilators (ERVs). In fact, sealing a home properly helps improve comfort, energy efficiency, and indoor air quality — as long as ventilation is part of the plan.
