Spray foam insulation in Jazan: the local context

Team note on Jazan: 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.. The centre of Jazan sits about 7 m above sea level (SRTM open elevation data).

Jazan is about 1.9 km from the sea coast (OpenStreetMap).

Is spray foam insulation worth considering for a restaurant in Jazan, given the coastal air and the heat? The centre of Jazan sits about 7 m above sea level, and the city is about 1.9 km from the sea coast. That closeness to the water means the building envelope faces salt-laden air and high humidity for much of the year, so the choice of insulation and its sealing matters as much as its thickness. For a restaurant, where kitchen heat, cooling loads and moisture from cooking all compete for the same space, a continuous air seal can make a real difference to comfort and to the running of the air conditioning.

Spray foam insulation for restaurant premises in Jazan is usually priced at SAR 20–45 per m², and this figure is a useful starting point when comparing it with other options such as XPS boards at SAR 12–30 per m². Where a site also has roof or wall exposure, liquid roof waterproofing at SAR 8–25 per m² and a bitumen membrane at SAR 15–35 per m² may be considered alongside the insulation. Our inspection begins with a walk through the kitchen, dining area and store rooms to note the surfaces that carry heat or moisture. The inspector then checks the roof, external walls and any gaps around pipes, ducts and doors, marking where the foam would seal the building. Cracks are recorded for separate treatment, with crack injection quoted at SAR 40–120 per metre. The final step is a short written summary of the surfaces, the proposed work and the prices that apply to each.

Before the visit, gather the drawings or floor plans of the restaurant, and note which areas are the kitchen, cold room, dining hall and any basement or storage space. Tell the inspector about any leaks, damp patches, stains or cracks you have already seen, and mention when they appear, especially after rain or during humid months. Also share details of the roof type and any work done to it previously. If you have a service schedule for the air conditioning or extraction system, have it ready, as it shows where heat and moisture currently enter the building.

For restaurants, visits are planned outside service hours and recorded for the premises file.

When do you need spray foam insulation?

The following signs are worth checking before they grow:

• Thermal and water insulation needed together
• A hot metal-sheet roof or hangar
• Leaks from the panel joints

Where the problem usually comes from

• A common cause: no UV protection on the surface.
• Joints in metal sheets and sandwich panels.

Tools and methods, and when we use them

The steps in order

1. Survey: Joints, fixings and gutters are checked.
2. Preparation: The surface is cleaned and dried.
3. Spraying in layers: Foam is applied in passes to the agreed thickness.
4. Protection: A UV-resistant top coat protects the foam.
