Spray Foam Insulation (Polyurethane) in Ad Dirah, Riyadh
Azl — delivered with a written warranty, to the Saudi Building Code
About Ad Dirah
Ad Dirah is the kernel of old Riyadh, home to Masmak Fortress, Qasr Al Hukm and historic markets, and still keeps mud-brick buildings with traditional roofs beside modern commercial blocks. Heritage buildings need breathable insulation materials that do not trap moisture, while the commercial blocks need roof waterproofing and thermal insulation to cut facade heat gain. District guide
Why Ad Dirah homes need spray foam insulation (polyurethane)
Ad Dirah lies in central Riyadh along Al Thumairi Street, and is dominated by shops and commercial buildings, older traditional houses and apartment buildings. On commercial buildings foam lowers the cooling load of large open spaces and is installed quickly with minimal disruption. Buildings in the old parts of the city need concrete and rebar checks before insulating, because insulation over damaged concrete does not last. In the city's intense heat spraying is scheduled in cooler hours to keep the substrate within the manufacturer's limits. The fix: spray foam in phases by building use, with a walkable protective coat.
