5 truths about SPF insulation – #4: SPF roofing is easy to install.
Spray Polyurethane Foam (SPF) roofing insulation is by far the easiest commercial roofing solution to install. The key to SPF’s installation process is two actions: mixing and reacting. SPF is typically created from two liquid bases:
- Base “A”: typically a compound of methylene diphenyl diisocyanate (MDI) and/or polymeric methylene diphenyl diisocyanate (pMDI).
- Base “B”: typically a hybrid of blend of polyols, catalysts, flame retardant, surfactant, and the required blowing agent for installation purposes. (Source: SprayPolyurethane.org)
The two base liquid mixes are typically transported to the installation site in large drums. A spray applicator is connected with lead lines to the drums. Upon application, the two base liquids mix, causing a chemical reaction. The immediate expansion process begins where the spray foam as its now called permeates and seals any exposed opening, crack, crevice, even the slightest gap.
The end result is a moisture-repellant, monolithic roofing cover that bonds and strengthens any existing roofing structure. In truth, the installation of SPF roofing is as easy as mix, spray, seal. No flashing, roofing joints, or panel fasteners are required with SPF roofing, just a thorough application with minimal preparation needed.
