PU Foam Spray in Pakistan, Polyurethane Roof, Wall & Ceiling Insulation 2026
PU Foam Spray (Polyurethane Foam) is a high-performance insulation material applied directly to roofs, walls, and ceilings. After application, it expands into a seamless layer that blocks heat transfer and seals gaps, its closed-cell structure traps tiny air pockets, keeping buildings cooler in summer and safer during the rainy season. At interiorsolutions.pk, we supply PU foam spray material and DIY sealant kits, and can connect you with professional application services across Pakistan.
What Is PU Foam Spray and How Does It Work?
PU foam spray is created by mixing two chemical components, polyol and isocyanate, which expand on application to form a dense, rigid foam. The foam adheres to concrete, metal, and wood, filling every crack and gap. Once hardened, it creates an airtight, waterproof, and highly durable insulation layer.
PU Foam Spray vs Thermocol vs Other Insulation
| Factor | PU Foam Spray | Thermocol/EPS Sheet | Chemical Roof Coating |
|---|---|---|---|
| R-value (insulation power) | Highest | Good | Lower |
| Waterproofing | Fully airtight and waterproof | Waterproof but has seams | Surface only |
| Gap/crack sealing | Fills every crack seamlessly | Leaves joints between sheets | No gap-filling |
| Price per sq ft | PKR 100–800 | PKR 22–75 | PKR 40–150 |
| Lifespan | 20–25 years | 10–15 years (protected) | 3–5 years |
| Best use | Complex roofs, seam-free need | Budget flat roofs | Quick surface reflection |
See our Roof Heat Proofing guide for a full breakdown of all three methods together.
PU Foam Spray Price in Pakistan, 2026
| Application | Price per Sq Ft (PKR) |

Where PU Foam Spray Is Used
Roof Heat & Waterproofing, the highest R-value among insulation materials, seamless protection with no joints, acts as both a thermal barrier and waterproof membrane in one application.

Wall Insulation, open-cell foam is softer, great for interior walls and soundproofing; closed-cell foam is denser and water-resistant, ideal for roofs and exteriors.
Cold Storage & Industrial, spray foam controls temperature, reduces condensation, and strengthens the structure. See our Water Tank Insulation page for a related residential application.
Sealing Windows, Doors & Pipes, prevents air leakage, fills gaps and cracks in walls and cavities, reduces heat loss from hot water pipes and prevents freezing.
Soundproofing, absorbs noise effectively, a preferred choice for studios, commercial buildings, and homes near noisy roads.
Application Process
Surface Preparation, clean and dry the roof surface
Spray Application, high-pressure spray equipment expands the foam and fills all gaps, creating an airtight seal
Coating (Optional), a UV-protective top coat adds extra heat and weather resistance
Inspection, technicians check for even coverage with no weak spots
Application is quick, installed in a few hours with no need to dismantle the existing roof.
Results You Can Expect
PU Foam Spray reduces roof heat by up to 90%, and AC costs typically drop by 30–40%. Foam density of 35–45 kg/m³ is ideal for residential insulation, always confirm this specification when getting quotes.
Lifespan: typically lasts 20–25 years if applied correctly, requiring little to no maintenance. Check for UV damage on exposed surfaces every 5–7 years and reapply protective coating if necessary.
DIY Kits vs Professional Application
DIY kits (small jobs only): Akfix-type gap filler kits (2×12 Oz) cost approximately PKR 4,800, suitable for sealing gaps around windows and doors.
Professional application: uses high-pressure spray machines for even application, imported PU chemicals ensuring density and fire resistance compliance, and trained technicians who avoid gaps or over-expansion. For full roof coverage, professional application is strongly recommended.
