About Jalmudah
Jalmudah lies in the north-east corner of Jubail Industrial City, surrounded by the Gulf to the north, east and south, with Al Fanateer to the west, and divided by Road 6. One of the newer districts, with villas and flats, it faces high humidity and salt from the surrounding sea, so foundation waterproofing from the build stage and roof insulation with a vapour barrier are advisable. District guide
Why Jalmudah homes need roof insulation
Villas and apartment buildings define Jalmudah in north Jubail, beside Road 6. 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. The industrial character means loads, traffic and chemicals, so heavy-duty systems with chemical-resistant layers are chosen. The fix: an integrated waterproof and thermal system turned up the parapets, detailing every base and opening, then a flood test before covering.
