Azl — delivered with a written warranty, to the Saudi Building Code
About Hajr
Hajr is Dhahran's northernmost district, on King Abdulaziz Road and Prince Mohammed bin Fahd Road, separated from Dammam's districts by Prince Mutaib Road; it covers about ten million m² and lies near Ithra. Large villas and palaces are common, so projects here call for comprehensive thermal and waterproofing systems for extensive roofs, pools and any basements. District guide
Why Hajr homes need spray foam insulation (polyurethane)
Hajr lies in north Dhahran along King Abdulaziz Road and Prince Mohammed bin Fahd Road, and is dominated by villas. Spray foam suits detail-heavy villa roofs because it covers them in one seamless layer insulating against both heat and water. High humidity affects bonding and curing, so application is scheduled in the least humid hours. In the city's intense heat spraying is scheduled in cooler hours to keep the substrate within the manufacturer's limits. The fix: closed-cell foam at the thickness set by the thermal calculation, then a UV-protective topcoat.
