Why Ar Rayyan homes need roof insulation
Ar Rayyan lies in west Unaizah along Sheikh Abdullah Al Bassam Street and Al Wazir Ibn Sulaiman Street, and is dominated by villas and shops and commercial buildings. 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.
