What is specific about Alqunfudhah for spray foam insulation

Team note on Alqunfudhah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Schools in Alqunfudhah often have large flat roofs and long exterior walls, and the most common insulation problem for this property type is heat getting through the roof and upper walls during the long, hot months. Classrooms that sit under an uninsulated roof can become hard to use by midday, and the air conditioning then runs harder than it should. Spray foam insulation fills gaps and covers irregular surfaces, which is why it suits school roofs with drainage slopes, parapets and service penetrations. Our spray foam work is priced at SAR 20–45 per m², and the final figure depends on the area and the condition of the surface underneath.

The local setting shapes how we approach each school. The centre of Alqunfudhah sits about 7 m above sea level, and the town is about 0.4 km from the sea coast, so the air is humid and salt-laden for much of the year. Moisture and salt can work into roof edges and wall joints, so we check how the existing surface is holding up before any foam goes on. Where roof waterproofing is also needed, liquid roof waterproofing is priced at SAR 8–25 per m², and a bitumen membrane at SAR 15–35 per m², so the two jobs can be planned together rather than treated as separate visits. Where cracks run through walls or floor slabs, crack injection is charged at SAR 40–120 per metre, and it should be dealt with before the insulation goes on.

Before the visit, it helps to have a few things ready. Ask the school to share the roof area, the number and type of roof drains, and any past leaks or repair records, since these decide the scope and the materials. Ask whether the building has a basement, a water tank or a separate bathroom block that also needs attention, because basement waterproofing (SAR 50–150 per m²), bathroom waterproofing (SAR 15–40 per m²) and tank internal coating (SAR 25–60 per m²) are priced differently. Ask about the timing too, so that work does not disrupt term time. With these details in hand, the site visit can give a clear and realistic picture of what the school needs.

For schools, the larger jobs are planned for weekends and holidays.

Signs worth paying attention to
