What does closed-cell foam mean, exactly?
As the name suggests, closed-cell foam has a cell structure that is denser – or more ‘closed’ – than other common foam types.
During production, materials are tightly pressed to reduce the space between each cell. This leads to an altogether more rigid, tightly-packed foam that provides a strong barrier against air and water.
There are several common types of closed-cell foam on the market, including polyurethane and polyethylene varieties. It’s often used in its spray form – particularly for insulation purposes – but closed-cell foam sheets, blocks and rolls are also widely available.
Is closed-cell foam waterproof?
Closed-cell foam is water-resistant, unlike its open-celled counterparts. Its dense cell structure makes it naturally resilient against moisture, but low levels of water absorption do occur in the majority of closed-cell foam types.
Waterproof closed-cell foam is available only in the very highest densities. Common applications for this kind of foam include door panels and water shields inside cars and other vehicles.
Is closed-cell foam insulation safe?
Closed-cell foam insulation is generally considered safe once cured, however, timings for this process can vary between applications. General guidance is to steer clear of areas where closed cell spray foam has been used until it has hardened fully.
Once cured, closed-cell foam boasts a higher level of thermal resistance than lower density foams. For this reason, it is widely thought to be the safer option for building and vehicle insulation.
What is the R-value of closed-cell foam?
The R-value of closed-cell foam can be anything between R-6.5 and R-7 per inch. R-value is a widely acknowledged measurement of thermal resistance.
This higher R-value is what causes it to be a strong barrier against heat, which in turn improves the foam’s fire retardancy. Closed-cell foam is, therefore, a popular choice for applications where fire safety is a key consideration, including within the aviation and railway industries.
