Spray foam insulation has revolutionized the way we insulate homes and buildings, offering unparalleled benefits in energy efficiency, comfort, and sustainability. Unlike traditional insulation materials like fiberglass or cellulose, spray foam insulation expands upon application to fill gaps, cracks, and hard-to-reach areas completely. This seamless coverage creates an airtight barrier that effectively prevents air leakage, one of the primary sources of energy loss in buildings.

Energy Efficiency and Cost Savings

One of the standout advantages of spray foam insulation is its ability to significantly reduce energy consumption. By sealing air leaks and providing superior thermal insulation, spray foam helps maintain consistent indoor temperatures throughout the year. This thermal efficiency translates into lower heating and cooling costs, offering homeowners and businesses substantial savings on their energy bills over time.

Enhanced Comfort and Air Quality

Beyond energy savings, spray foam insulation contributes to enhanced indoor comfort by minimizing drafts and temperature fluctuations. Its ability to block moisture intrusion also helps prevent mold growth and improves indoor air quality. Unlike traditional insulation materials, spray foam is resistant to water and does not provide a food source for mold or pests, making it a durable and long-lasting solution for buildings of all types.

Environmental Sustainability

From an environmental standpoint, spray foam insulation aligns with green building practices. Its durability and longevity reduce the need for replacement and minimize waste. Additionally, the energy savings achieved through improved insulation can lower greenhouse gas emissions associated with heating and cooling, contributing to a more sustainable built environment.

Spray foam is a premium insulation that delivers multiple benefits, including superior energy performance, reduced air leakage and improved occupant comfort. It also seals penetrations and other areas that are difficult to reach with other types of insulation. These features result in lower energy bills and reduced greenhouse gas emissions.

Attic insulation polyurethane foam (SPF) is a type of insulation that is sprayed on site, expanding to fill gaps and nooks and crannies, providing unmatched air sealing properties. It is a flexible and light material that conforms to the unique design of a building or structure.

Beyond Traditional Insulation: The Modern Marvel of Spray Foam Solutions

Professionally installed 2lb medium density spray-applied SPF insulation offers a wide range of R-values depending on the application and construction method. The higher the R-value, the greater the insulating power.

A key factor in achieving the best results is using a high quality installer who follows industry standards and provides a complete service package. This includes a thorough inspection and analysis of the home, a detailed written report with recommendations, and a comprehensive warranty.

To perform the job properly, crews prepare the area by covering flooring, windows and doors with plastic to prevent any accidental contact with the spray. They will run a hose through a spray gun to atomize the liquid chemicals and create the foam. The chemicals travel through a nozzle, creating a foam that is up to 60 times its liquid volume when fully cured.

The chemistry of spray foam involves two main ingredients, known as A-side and B-side. The A-side, often called isocyanate, contains a type of flammable chemical like methylene diphenyl diisocyanate — more commonly referred to as MDI — and polymeric methylene diphenyl diisocyanate (pMDI). It is similar in composition to Gorilla Glue and should not be inhaled. The B-side contains polyols, a catalyst, blowing agent, surfactant and flame retardant. The reaction between these chemicals produces a closed cell foam that is safe once it dries and cures.

EWI is a thermally floor insulation , protective and decorative exterior cladding process. It involves the application of 70mm rigid foam insulation (Kingspan, Celotex or similar) mechanically fixed to the walls and then clad with a sand and cement render or timber cladding. It’s an excellent solution for older properties built with solid brick.

EWI can significantly improve the energy efficiency of your home or commercial property. By limiting the amount of heat that escapes through the external walls and roof, you can reduce your dependence on artificial heating and cooling systems.

It can also reduce condensation on the wall which can lead to mold and rot and increase your indoor air quality. It can also help to prevent noise escaping from outside, helping you have a peaceful and comfortable living environment.

Unlike internal insulation, external is non-invasive so it won’t interfere with your daily routine and the walls remain fully functional during the works which can take around 3 weeks on average for a 100m2 house. It’s an excellent option for those who have access issues such as a tight alleyway that would make it difficult to use scaffolding or are located in a conservation area where planning permission may be required.

Most EWI installers will carry out a survey to determine the condition of your existing brickwork before advising you on the best solution. If the existing brickwork is in good condition, external wall insulation could be a suitable option as it doesn’t require the removal of any of the bricks. However, it’s still important to contact your local council for advice before starting the work as they may have specific rules regarding solid wall insulation in Conservation Areas or listed buildings.
