Vinyl siding is resistant to stains, peeling, rot, and dents; and scratches are not easy to see.
People may worry about the flame resistance of vinyl, which is actually polyvinyl chloride or PVC. It might melt, but it won't continue to burn without contact with the flame.
Vinyl ignites at about 700 degrees, Pine and paper ignite at around 450 degrees. The fumes are not healthy to inhale, but would tend to put the fire out. The smoke is unhealthy, but there is less of it...The HCl it produces would create a warning smell or irritation long before a toxic amount can be inhaled. This contrasts with carbon monoxide and CO2, the other products of burning PVC and any wood or paper products. All three gases in the smoke tend to extinguish actual burning of the siding.
Firemen have felt that vinyl siding has helped to contain house fires, or to prevent an adjacent fire from involving the next house. Of course the vinyl will sag and smoke where another siding would blister, peel or burn.
Airplane upholstery looks similar to vinyl fabrics, but it burns quickly and release phosgene gas, a poisonous gas that has been used in war but is now banned.
Vinyl siding is slightly insulating without our foam insulation. It tends to protect from frost and condensation. It is also an electrical insulator, so doesn't need to be grounded from lightning or stray electric lines in a wildfire situation.
It is available in almost any imaginable color—nonfading, and in many different textures and patterns. And you don’t ever need to paint it!!!!
