Helping to reduce the carbon footprint of your home and improve your green credentials.

Closed-cell Spray Foam

Closed-cell spray foam insulation is one of the most efficient insulating materials commercially available, with performance far greater than conventional insulation that leads to energy efficiency, improved occupant comfort, a cleaner indoor environment and greater noise reduction for building and home owners.

Open-cell Spray Foam

Open-cell spray foam is a thermal insulation material that expands 120 times its initial volume, fills cavities of any shape, and adheres tenaciously to most building materials and framing material.

What are the benefits of spray foam?


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 spray foam a more attractive option. The savings begin immediately upon installation.


Once 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 the seal created by the spray foam installation will help reduce cold and hot spots within the home as gaps are closed, contributing to an even temperature within your property. If your home is near a noisy area, the spray foam seal will even help reduce the volume of any external noise.



Synthesia’s airtight spray foam insulation has many protective benefits for the home. It restricts air movement, which stops moisture accumulation so mould growth is less likely to occur. Once the spray foam has solidified, pests of all kinds will also find it difficult to enter your home through the now sealed areas.


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..


Current guidelines recommend up to 10 inches of insulation in your loft. This is usually added to the ground, rather than the roofline, 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 roofline, you regain the lost 10 inches, thus increasing storage, height and practicality. Reclaim your loft space!



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.
