Spray Foam Insulation FAQs
Over ten years of spray foam expertise has given us a vast technical knowledge. Some of the most common questions are answered below.
What are the differences between closed-cell and open-cell foams?
We do not recommend open cell foams for treatment of condensation to any substrate that is impermeable. This includes, profiled steel roof and wall cladding and non-breathable roofing felts. The poor vapour resistivity of open cell foams can lead to interstitial condensation and subsequent waterlogging of the insulation.
How are polyurethane foams applied?
What equipment is required?
Are there any special handling considerations?
While spraying, always work with adequate ventilation. Protective gloves and face masks are mandatory. When atmospheric levels may exceed the occupational exposure limit (PEL or TLV), approved air purifying respirators equipped with an organic vapour sorbent and particulate filter can be used as long as appropriate precautions and change-out schedules are in place. Persons with known respiratory allergies must avoid exposure to the A component.
What is the insulation U-value of your systems?
What are the differences between roofing foams and wall foams?
What is an insulating air barrier system?
Does polyurethane technology control air leakage?
Can an insulation system add structural strength?
Closed cell foam injected into a cavity, has enough strength to bond two leaves of a masonry wall together, in situations where the existing wall ties have failed.
