• A semi-rigid 1.91b density closed cell spray foam.
  • BaySeal closed cell foam has the highest aged R-value of any spray foam at 6.9 per inch!
  • This foam is a one shot air barrier and vapor retarder.
  • Suitable for use in wall assemblies, sprayed directly to underside of roofs, stone foundations, crawlspaces or anywhere else superior insualtion is required.
  • Polar Pro is the cold weather version of the closed cell. It also comes in a 3.01b density for use in roofing applications.
  • SPF Roofing from Covestro is a Cost-Effective, Long-Term Facility Solution
  • SPF roofing can be applied over the existing roof, so tear off may be unnecessary; save time and divert waste from landfills.
  • The adhesive nature of SPF eliminates metal fasteners used to secure the product to the deck, so no roof penetrations are made
  • SPF is self-flashing; metal counter flashing is not required.
  • SPF is easily sprayed around piping or other roof penetrations.
  • SPF helps minimize the migration of moisture through the roof.
  • Rooftop modifications can be made easily. New SPF applications are applied over existing foam.

Closed cell foam

Closed cell foam






1
Closed cell foam is a denser and harder cellular plastic. It has all of the positive attributes of open cell foam without the limitations. The millions of tiny cells in the foam are closed. Inside the cells, there is trapped blowing agent (one component in the foam).
2
Solstice is the next generation blowing agent and is in some of the foams that we carry. It is more environmentally friendly than the previous version, but we don’t want to get into those differences right now! All you need to know is that Solstice has zero ozone depleting potential and a low global warming number of one (the same as carbon dioxide)! Back to the foam.
3
The blowing agent trapped in the closed cells gives the closed cell foam a higher R-value than open cell foam; typically 6.6-7+ per inch! Because closed cell foams have greater that 90% of their cells closed, they are also a class 2 vapor retarder on their own. This is great in any climate, because at certain times of year, the warm side changes during the day.
4
Take NH for example; in October at night, it can be 30 deg F and the vapor retarder should be on the warm side, the inside. Then during the day it can get to 70 deg and the vapor barrier should be on the outside! With closed cell foam being a class 2 vapor retarder all on it’s own, it’s always on the right side of the wall or roof assembly!
5
Closed cell foam is naturally moisture resistant and is the absolute best insulation choice for damp areas such as basements and crawlspaces. It can also be used in places that might not come to mind right away; on foundation walls before they are back filled, outside oil tanks, even under concrete slabs! As an added bonus, closed cell foam adds significant structural integrity to wall and roof assemblies.
6
It fully adheres to whatever it is sprayed to, essentially gluing the structure together. Because it is so rigid, it is like adding blocking to the whole inside of a wall cavity increasing racking strength by 300%!
