Growfoam is a formulated polyol blend. Polyol blend is a mixture of base polyol and additives. Different mixtures have different characteristics that is suited to different end user applications.
RC and RO Series for Roofing
A type of rigid PUR foam that is designed to insulate buildings from heat and cold, typically used in the production of insulated roofing panels. Insulated roofing panels are manufactured by sandwiching the rigid PUR foam between the exterior profiled metal roofing sheet and facing materials such as PVC, metal sheet and paper using continuous process.
The rigid PUR foam used in roof insulation can be categorized as closed cell, open cell and semi-open cell due to the difference between the small bubbles (cells) that make up the foam :
Closed cell foam is made of cells that are encapsulated and closely packed together to prevent air and moisture penetration inside the foam. Therefore, closed cell foam is more dense, rigid, durable and good insulation. Some of it are formulated to pass B2 grade of DIN 4102 German Standards fire resistance test. The overall density ranging from 30 to 45 kg/m3.
Open cell foam is made of cells that are not completely encapsulated. The open cell foam is filled with air making it more lightweight, softer and more flexible. The overall density ranging from 16 to 18 kg/m3.
Semi-open cell foam has the characteristic of open and closed cell foam, with approximately equal ratio of these two cells. Semi-open cell foam is lighter than closed cell foam, thereby offering cost saving advantage to users. The overall density ranging from 20 to 25 kg/m3.
