Closed Vs. open
cell foam; what's the difference?
Closed Cell
Polyurethane Foam
The image on the left shows closed cell polyurethane foam (which Websters Insulation use). It is called ‘closed cell’ because the ‘windows’ are shut, making the foam very water resistant and an excellent thermal insulator.
Gas is trapped in the closed cells, giving the foam an R-value of around 7.14 per inch and uses high R-value blowing agents. The density range is between 9 to 15 kg per cubic metre.
Open Cell Polyurethane
Foam
The image on the left shows open cell polyurethane foam (which Websters Insulation do not use). It is called ‘open cell’ because the ‘windows’ are left open, offering no resistance to water intake and offering very little thermal insulation properties.
As the cells are open, the foam feels spongy to the touch, offering no stability unlike closed cell, which offers excellent stabilisation qualities. Open cell foam, while being slightly cheaper, offers no benefits whatsoever other than slight sound reduction if used in cavity voids.
