All buildings show expansion and contraction due to environmental conditions, like changes in temperature. Traditional insulation materials cannot adapt to these conditions. Spray foam insulation benefits from an open cell structure that can air seal your building at a lower cost. It is permeable in nature allowing moisture to be removed. The flexible nature of the substance allows it to expand and contract as your building does in different climate zones maintaining the air seal created.
Our fully trained specialists spray the product into what is known as your building's envelope. This is your studded walls, ceilings and floors. If you are renovating a premises our Lapolla LD-CP-50 our foam is used. We inject this directly into small holes drilled into your internal plaster walls or alternatively from the exterior wall. It is a safe product to use directly onto electrical and plumbing apparatus.
Generally it is a liquid made from polyurethane that is sprayed through a spray gun apparatus. When introduced to the atmosphere in a spray, the foam expands gradually up to 100 times its original volume. It is used in areas such as your roof space, either at joist or rafter level. This helps keep warm air in during the winter and helps your house stay cooler during the summer. The added benefit of this type of insulation is the benefit of sound insulation, thus reducing noise pollution.
It only takes a few minutes to cure. Upon spraying, it expands to 100 x its starting volume.
No it is a hydrophobic material, meaning it repels water. It made wet it dries quickly and the insulating properties remain. If for some reason water is forced into the foam, it will drain with no adverse effects.
It doesn't contribute fuel in any event of a fire and it will not continue to burn if the flames dissipate. It can be consumed by fire and gypsum board or other accepted thermal barriers are required by applicable building standards.
Simply put, no. It has been rigourously tested and is not a concern to electrical authorities. If being retrofitted you should have wiring checked so that any work needing done gets done and if being applied to a new build, the electrician should be informed that any non service area electrics will be encased by insulation.
No. Due to the chemical make up of the compound, Lapolla is stable. The reaction created is irreversible.
