Polyurethane Foam Insulation
Polyurethane foam insulation is a spray-applied foam that expands and cures into a single seamless layer that insulates against both water and heat. You need it when you want to stop roof water leakage and cut the heat transferred into the building under Saudi Arabia’s harsh sun.
01
The problem
Exposed roofs in Saudi Arabia endure extreme heat cycles that crack conventional layers, letting rainwater and roof-tank spills leak into the building — while the roof itself conducts heat indoors and drives up cooling loads.
02
The solution
We spray polyurethane foam across the entire roof so it bonds to the substrate and seals joints and corners, combining waterproofing and thermal insulation in one application, then protect it with a UV-resistant reflective coating. Executed by a specialized crew with high efficiency and guarantee.
What does execution include?
- Spray-applied on site as one continuous, joint-free layer
- Waterproofing and thermal insulation in a single application
- Bonds directly to concrete, metal and most substrates
- Follows complex roof details (plinths, pipes, corners)
- Finished with a UV-protective reflective topcoat
- Suitable for exposed or shaded roofs, new or existing buildings
Comparison: spray foam vs membrane rolls
| Aspect | Polyurethane foam | Membrane rolls |
|---|---|---|
| Application | Spray-applied, cures in place | Rolls welded and fixed to the roof |
| Seams | One continuous seamless layer | Welded joints between rolls |
| Insulation type | Waterproof + thermal together | Primarily waterproofing |
| Complex details | Covers corners and protrusions easily | Requires manual cutting and detailing |
| Best fit | Exposed roofs with reflective topcoat | Roofs to be covered by screed or tiles |
Service FAQs
Does spray foam replace separate waterproofing and thermal boards?
Often yes — a polyurethane layer acts as both a water and heat barrier at once; each project is assessed on site to set the right thickness and protection.
Can foam be applied over an old roof?
Yes — after inspecting and cleaning the surface and treating any existing damage, foam is sprayed directly to form a new continuous layer.
