At LCR Contractors we use spray foam products manufactured by North Carolina Foam Industries Polyurethanes (NCFI).

What is Spray Foam Insulation?
Spray Polyurethane Foam (SPF) Insulation is a complete insulation, air and moisture barrier system that wind proofs and seals wall, floor and ceiling cavities against air movement, including spaces around electrical outlets and light fixtures, at baseboards and where walls meet windows and doors. This means that outside air (either hot or cold) cannot seep through walls, causing drafts or cold spots. It also means that humid interior air cannot enter the walls and condense. SPF is produced by a chemical reaction when two liquid components are combined, an isocyanate, known as the "A" component, and a polyol resin, known as the "B" component. When the two liquids are mixed together (typically at a one-to-one ratio), a chemical reaction occurs creating rigid, or semi-rigid foam. The mixed liquid starts to react in seconds, expanding 20 to 30 times its liquid state (100 to 150 times for open cell foam). Once cured it solidifies and becomes polyurethane foam.

Foam insulation is sprayed in place by trained professionals as a liquid and then expands many times its original volume in a matter of seconds to fill every nook and cranny, crack and crevice, and tight spaces that traditional insulation materials cannot get to. Building cavities, the air sealing characteristics of foam insulation provide virtually the same R-Value in the field as it does in the laboratory where the R-Value is measured. Cold air in winter and hot muggy air in summer just cannot pass through spray foam like it can through most other insulating materials.

Studies have shown that as much as 40% of a building’s energy loss is due to heat loss, or gain, through walls, roofs and windows. SPF is an incredible material for roofing systems and thermal insulation with its excellent water resistance and ability to air-seal your home or building with R-values ranging to 6.5 to 7.0 per inch. This efficiency contributes to significant energy savings throughout the life of a building and benefits the owner allowing the use of smaller capacity cooling and heating equipment.

Is Spray Foam Insulation Safe?
Yes, cured spray polyurethane foam is relatively inert and studies indicate that SPF does not release toxic gases or leach harmful chemicals into the soil

Are there Building Code Approvals?
NCFI Foam Insulation Products are in compliance with the 2006 IBC, IRC and IECC.

Can I afford Spray Foam Insulation?
You can't afford not to use Spray Foam Insulation. Yes, it does have a higher initial cost compared to traditional insulations; however, spray foam insulation will give immediate pay back. The size of HVAC system needed will be reduced and your monthly energy bill will be significantly lower.
