What is Spray Foam Insulation? Is it Safe?

03 Feb

If your house was built after the 1920s, it could be a hollow wall. If it has not been built in the last 20 years, these cavities may be empty. If this is the case, filling the wall insulation can be a very economical way to keep the heat in your home and save energy costs.

Approximately one third of the heat loss in most homes is through walls, so cavity insulation can save up to 160 pounds per year for heating. In fact, according to the website of the Trust of Energy Conservation, he can pay for himself in less than five years.

Air passes through each hole, cracks and cracks move inside and outside the house. About 33% of the air penetrates into walls, ceilings and floors. To achieve the best building characteristics, it is necessary to add improved insulation systems. Lapolla is a type of advanced insulation system.

The insulation of the foamable foam maximizes the investment of the homeowner, sealing the shell of the building, preventing the escape of air from the conditioned room and preventing the entry of uncontrolled air into the house. Air exchange into and out of the room is the main reason for the growth of electricity bills. The heating and cooling of the building mechanical system continues to work, reducing extreme temperature changes can save the mechanical system from excessive use and lead to a reduction in energy costs.

A sprayed or injected foam (commonly referred to as a spray foam) has a K value in the range of 0.025 to 0.028 W / mK and, therefore, provides a very high insulation value.

Spray foams are produced locally using specialized equipment and are manufactured by highly qualified and approved installers to ensure quality control and performance.

 

Insulating materials for spray foam can be closed or opened. Low thermal conductivity with closed holes, can be used for stabilization, less air leakage, water stop. Open-cell foam is more breathable, has better acoustic properties and costs less than insulation with closed cells.

Main insulation

According to the Environmental Protection Trust, 25% of the heat loss in households falls on the roof, 35% on walls, 25% on air leakage or ventilation. Therefore, hollow walls and an attic / roof are one of the most effective measures to increase energy efficiency for houses.

Foaming foams can be used for various insulation applications, including: attics / roofs, attics, walls, floors, ceilings and filled voids and gaps.

Foam helps reduce heat loss and risk, reducing energy costs and making your home more comfortable. In a warm house, you can reduce the heating in half – not only save energy and money, but also helps extend the life of the boiler.

Commercial insulation

Not only can internal properties benefit from proper insulation, many commercial buildings can use foam insulation, including: factories, warehouses, trade / exhibition spaces, offices, soffits and agricultural buildings. For many of these foams, this also helps to prevent surface and gap condensation, which gives advantages for the use of these buildings.

Polyfoam foams are very versatile and have a variety of different insulating materials and technologies designed to meet different types of property and requirements in projects of various industries.

To learn more about foam insulation and polls and quotes, click on the link below to find the NIA foaming installers in your area.

You know that the NIA installers have signed our strict professional practice, which means that members approved by the NIA can confidently use these standards.

These figures are estimates for England, Scotland and Wales and are based on isolated gas houses. The actual payback period will depend on the date of installation of the insulation, since the amount saved each month will vary depending on the winter and summer. The average installation cost shown here does not change.

The cavity wall consists of two separate thin walls (usually consisting of bricks and called “skins” or “leaves”) with gaps (or cavities) between them. They are mounted on the wall together with metal.

As we mentioned above, your family’s age is the first key. However, if you do not know how big it is, or if you think that it was built around 1930, it could be an empty or solid wall and look at any open brickwork. If your house has a hollow wall, all the bricks look the same, for example:

If all the brick walls in your house are covered or covered, so you will not see any real bricks, you can see the thickness of the facade.
