Spray foam, “Poor man’s spray foam” (sheets of foam insulation cut undersized and sealed airtight with one part spray foam cans) or dense packed cellulose.

Our insulation delivers a number of benefits beyond thermal performance in external walls , such as best in class fire resistance, exceptional noise reduction, water repellence as well as vapor permeability, and dimensional stability - meaning excellent fit and real world performance, for the lifetime of the building. Fiberglass is easy to cut, so if your stud spacing is irregular, buy batts that will fill the widest bays, and trim the rest to fit. On open walls , a fabric sheath is attached to studs, providing a type of cage that contains blown-in fiberglass (not cellulose) insulation , in pellets and other forms.
