Spray foam insulation
Cellulose insulation

spray foam

There are two types of foam insulation used in residential building projects, open and closed cell.  Closed cell foam is both vapor and air impermeable and offers a high R-value, while open cell foam is only air impermeable and offers a R-value comparable to other products. Despite these important differences, both provide excellent air sealing, good to excellent insulation properties, while commanding a premium installed price.


A go-to choice for green builders, cellulose is made from ground up newspaper, containing between 75% to 80% recycled content.  Great for both retrofit and new construction projects, cellulose offers low to moderate air sealing properties, comparable R-values, nontoxic fire retardants, sound reducing properties, and a low to moderate installed cost.

Fiberglass insulation


The most common insulation found in existing homes across the country, fiberglass is made from fiber-reinforced plastic.  A cost effective solution, fiberglass offers comparable R-values, but poor air sealing properties.  Getting the installation details correct is critical as its overall effectiveness is dependent on this. 

Rigid foam insulation

Great for a continuous insulation barrier on exterior walls, foundations and roofs, rigid foam provides excellent insulation and air sealing properties when seams are taped or foamed.  Although rigid foam commands a moderate installed price, it can greatly improve overall insulation R-values and can extend the life of other building materials.

Roxul insulation


Roxul is a fire-resistant insulation that's made from stone.  Roxul does not support mold or fungal growth, it doesn't burn or release toxic gases or smoke when exposed to high heat,  provides average to above average R-values, and provides sound reducing properties.  A moderately priced and installed product, Roxul is commonly found in wall, rim joist, and between floors as a sound dampening solution.
