Roof Insulation in Az Zahra, Qatif
Azl — delivered with a written warranty, to the Saudi Building Code
About Az Zahra
Az Zahra in Qatif runs along Tarout Bay to the north and west, with An Nasirah to the south, and includes a waterfront residential project. Proximity to the sea brings humidity and salt in the air and soil, so new villas need salt-resistant waterproofing for foundations and roofs, plus thermal insulation that prevents condensation on inner surfaces. District guide
Why Az Zahra homes need roof insulation
Villas and apartment buildings define Az Zahra in north Qatif, beside Al Bara bin Azib Street. Villa roofs are wide, multi-level and crowded with AC bases and annexes, and every joint or opening is a weak point for rain or AC condensate. Being near the sea means humidity and salt that speed rebar corrosion and affect curing, so surface moisture and dew point are checked before any application. Many buildings in the district are under construction, and the best time to insulate is before tiling and backfill, with a flood test before covering. The fix: an integrated waterproof and thermal system turned up the parapets, detailing every base and opening, then a flood test before covering.
