Open-Cell Foam

AirTight™ Retrofit Foam helps create an air barrier system in wall cavities and may be used to incrementally fill an existing cavity wall or block wall assembly from the bottom to the top in a progressive application.

This installation method allows an existing cavity wall to be insulated without the removal of the interior face of the wall, providing an air barrier and insulation of the wall with minimal impact to the wall cavity.

The BENEFIT of this is reducing the time, labor and the expense of removing and replacing the existing interior face of the wall. In block wall assemblies Retrofit Foam may be used to incrementally fill the interior cavities of the block to supply insulation and minimize the air leakage and heat transfer of the assembly.

Spray foam is one of the most efficient and modern insulation methods available on the market today. With the costs of energy bills rising every year, no matter which provider you choose, consumers are seeking alternative methods to help warm their home. At Lapolla Industries UK, we recommend to customers keen to reduce the costs of their utilities that they have our spray foam installed into their property.

Money Saving Benefits

Installing spray foam insulation will help save you and your household money every year. The spray foam will seal air within the property and help prevent heat loss; this will make it cheaper to warm your home in the winter and help you save money every year. If you wish to sell your home in the future, buyers will find buying your property with a more attractive option. The savings begin immediately upon installation.

Health Benefits

Many illnesses like asthma and allergies are often caused by airborne pollutants such as dust, dirt, carbon monoxide and many more. By choosing spray foam insulation, your home will be sealed from a wide range of pollutants in the air. Many customers notice a positive difference in their health after installation.

Increased Comfort

As our spray foam insulation is installed, you will find that your home is more comfortable than ever before. Drafts will be a thing of the past as they will be eliminated in your home. The seal created by the spray foam installation will help reduce cold and hot spots within the home as gaps are closed. This contributes to an even temperature within your property. If your home is near a noisy area, you will not have to suffer anymore as the spray foam seal will help reduce the effect of noise.

Structural Improvement

Spray foam insulation can help support the overall structure of your property. This is dependent on the application and thickness of the spray foam on installation.

Protects Your Home

Lapolla’s AirTight spray foam insulation has many protective benefits for the home. It restricts air movement, which stops moisture accumulation so that the possibility of mould growth is less likely to occur. A huge benefit of spray foam insulation is that it helps deter pests from entering your home. Once the spray foam has solidified, pests of all kinds will find it difficult to enter your home through the now sealed areas.

Reclaim your loft

Current guidelines recommend up to 10 inches of insulation in your loft. This is usually added to the ground, rather than the roof line, which results in the loss of your storage area, due to not being able to refit floor boards after installation. By implementing spray foam insulation to the roof line, you regain the lost 10 inches, thus increasing storage, height and practicality – Reclaim your loft space!
