Foam roofing is made of polyurethane foam and an elastomeric layer.
An elastomeric layer is a water-resistant film that is meant to preserve the roof from rain, water, and sun. This material is used in foam roofs as an insulation material.
Foam Roof is a popular alternative for residencies and commercial buildings that use flat roofing because it has high durability, is relatively easy to install, and is energy efficient.
Spray Foam comes in two samples: open-cell and closed-cell.
Open-cell foam is normally restricted to interior foam insulation. In polyurethane foam roofing purposes, closed-cell foam has higher consistency and more reliable insulation against water and air infiltration.
To install a Foam Roof you need to create a mixture that combines isocyanate and polyol chemicals and spray it over a roof deck or underlayment. Once the mixture reaches the roof surface, it expands – stretching 20 to 30 times in size, or 1 to 1.5 inches – and produces a thick foam coating.
To make sure that the foam doesn’t get damaged by UV radiation, fire, and other natural elements, another layer of silicone or elastomeric needs to be applied.
