Azl — delivered with a written warranty, to the Saudi Building Code
About Ad Dir
Ad Dir in Dawadmi is crossed by Ad Dir Street and Khalid bin Numair Street, with villas offered for sale and rent. Villas with annexes and boundary walls need waterproofing on both main and annex roofs, thermal insulation of outer walls keeps rooms stable through the plateau's cold winter, and home gardens should be watched for ant nests and rodents. District guide
Why Ad Dir homes need roof insulation
Villas define Ad Dir in Ad Dawadmi, beside Ad Dir 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. The city's cold winters and hot summers cause repeated expansion and contraction, so a flexible system is preferred. Intense heat most of the year makes roof thermal insulation a core part of the solution, not an optional extra. The fix: an integrated waterproof and thermal system turned up the parapets, detailing every base and opening, then a flood test before covering.
