What is Icynene® Spray Foam Insulation?

Icynene® spray foam insulation is a unique insulation solution which can offer heating cost savings of up to 35%. Closed-cell Icynene® does not degrade over time unlike alternative insulation solutions, nor is it affected by humidity. This makes it a great investment for property owners.

Which spray foam insulation is best?

Closed-cell Icynene® spray foam insulation is the best form of insulation for exterior walls. The closed-cell material means it is not affected by humidity, and provides unrivalled protection against moisture and thermal resistance. However, open-cell spray foam insulation is better for soundproofing walls due to the lower density and higher concentration of air bubbles.

What is better: spray foam insulation or fibreglass?

Fibreglass has the lowest installation value than most types of insulation. It also does not absorb nor hold water, plus it is naturally non-combustible and remains so for its lifespan, as it is made from sand and recycled glass.

However, close-cell Icynene® spray foam insulation offers unbeatable resistance to moisture and in quickly installed. Due to its airtightness, it helps block airborne moisture from penetrating the cavities, and due to its expansion, fills out spaces more effectively than other insulation types.


Finally, if there is a plumbing or electrical problem behind the insulation, Icynene® is easily cut and removed, then refilled again. Other forms of insulation, such as fibreglass, present more problems as it is more difficult to remove. In summary, Icynene® spray foam insulation is often now a favoured solution due to fast application and enhanced insulation benefits.
