The Seven Major Advantages of Spray Foam Insulation

Foam insulation, once sprayed onto the underside of your roof, looks impressive, but it may seem more expensive than other options like traditional fibreglass rolls. Having spray foam insulation installed in your home may initially cost more, but the long-term savings and other advantages more than offset the initial investment. To create foam insulation, a polyol resin and an isocyanate are mixed together. Both of these ingredients are typically applied as liquids. When they come into contact with air, however, the foam expands to form a solid, protective layer that dries in a matter of seconds.

1. Reduced Risk of Mold and Mildew

Due to the lack of air circulation, mould and mildew have no chance of developing in an area sealed with closed-cell spray foam. This works exceptionally well in the roof space by reducing moisture and providing a complete seal.

2. The Benefits To Nature Are Obvious

Combating global warming requires everyone to do their part for the environment. There are a number of insulating materials on the market, but spray foam insulation is expected to help homeowners save money on their energy costs and last for a very long time. This is an excellent option if you’re looking for a green solution.

3. Effective Insulation

In order to reduce heat loss in the winter and control heat gain in the summer, spray foam insulation is commonly used. It is the best option for loft insulation due to its unique properties, and it can usually be installed in a single day. The high resistance value of professionally applied spray foam means that it can create an airtight seal with all its associated advantages.

4. Crevices and Gaps

One issue with classic approaches to roof insulation is that they often leave gaps in key areas where heat can escape. This can be a serious issue in older buildings, where the bricks and foundations may already be showing signs of wear and tear. The insulation spray expands to fill any gaps and blankets the areas that need it most. The insulating layer is, therefore, improved and more effective.

5. Reducing Energy Waste

Since fuel costs have been climbing steadily over the past few years, cutting costs wherever possible is essential. What this amounts to with spray foam insulation is a warmer home in the winter and lower energy bills throughout the year. The amount of improvement to a typical home from installing foam loft insulation will vary greatly depending on the existing level of energy efficiency in the building.

6. An Impermeable Shield

Insulation methods from the past, such as fibreglass, can trap moisture, which can lead to issues down the road. To prevent leaks in your roof, which can lead to costly repairs, consider spray foam insulation, which does not absorb moisture.

7. Durable protection

Some forms of insulation can be damaged by foot traffic or simply lose their form over time. Spray foam insulation is a long-lasting product that can be used for many years. If properly installed, loft insulation can last for more than twenty-five years after the initial application.


For optimal results, spray foam installation should only ever be attempted by those who have been trained in the proper chemical combinations and application procedures. Do-it-yourself spray foam installations present a potential hazard and can be extremely unpleasant. In addition, if insulation is installed incorrectly, gaps will form, rendering the entire project useless and yielding subpar results. Always hire qualified professionals to install your roof insulation.
