Spray Foam

Houston Spray Foam Supply Co. in Houston, TX, offers two types of spray foam available for wholesale distribution. Read more below on the benefits of both types.

Types of Foam Available

Open-Cell Spray Foam

Open-cell spray foam gives a bit more flexibility than closed-cell and tends to expand more. Open-cell spray foam insulation is more economical, and it also expands more, allowing more air circulation than closed-cell spray foam.

Closed-Cell Spray Foam

Closed-cell spray foam is the best choice when insulating where space might be an issue. Closed-cell spray foam doesn't expand as much as open-cell spray foam but seals well enough to act as a vapor barrier.
