The “pros” of installing spray foam insulation

air leakage is virtually eliminated.
an air-tight seal prevents heat loss.
home energy efficiency is assured.
seasonal energy bills are lowered.
ideal for attics, roofs, walls, floors.
higher R-Value than other installs.
moisture accumulation is reduced.
