PU foam spray, also known as Polyurethane Foam Spray, is one of the most effective insulation solutions used across Pakistan for both residential and industrial applications. It provides seamless coverage, excellent heat resistance, and waterproof sealing — making it ideal for the country’s extreme weather conditions.
Whether you live in Lahore, Karachi, or Islamabad, PU foam spray can drastically improve temperature control and reduce electricity costs for cooling or heating.
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 surfaces like concrete, metal, and wood, filling every crack and gap. Once it hardens, it creates an airtight, waterproof, and highly durable insulation layer.
PU foam spray has a wide range of uses. Its flexibility and high insulation power make it suitable for multiple environments.
The most common use of PU foam spray in Pakistan is for roof insulation.
It helps in:
Applied inside walls and ceilings, PU foam creates a barrier that prevents heat transfer. This is particularly beneficial for offices, warehouses, and commercial buildings where temperature control is essential.
PU foam spray is heavily used in cold storage units, food processing plants, and pharmaceutical industries to maintain low temperatures and prevent energy loss.
It is ideal for insulating air ducts, pipelines, and HVAC systems — ensuring efficiency and minimizing condensation.
PU foam spray can reduce air conditioning costs by 30–40% by keeping buildings naturally cool. In cities like Lahore or Karachi, where summer temperatures often exceed 40°C, this insulation provides significant comfort and savings.
Unlike thermopore or fiberglass, PU foam forms a single, joint-free layer that prevents water seepage and leakage, even on flat roofs.
The dense structure of polyurethane foam absorbs sound vibrations — ideal for apartments, studios, and offices near noisy streets.
With a lifespan of over 20 years, PU foam spray does not shrink or crack over time, ensuring consistent insulation performance.
Modern PU foams are CFC-free and eco-friendly. They help lower overall carbon emissions by reducing excessive use of cooling systems.
The surface (roof or wall) is cleaned of dust, oil, and debris to ensure proper adhesion.
Two liquid chemicals (polyol & isocyanate) are mixed using a specialized spray gun. The foam expands instantly on application, covering the entire area evenly.
The foam expands up to 30 times its original volume, sealing gaps and cracks. It hardens within minutes and becomes durable enough to walk on.
A protective paint or UV-resistant coating is often applied to prevent sun damage and improve the foam’s lifespan.
The required thickness depends on the purpose:
On average, 1 kg of PU foam covers around 1 square meter at 1-inch thickness.
PU foam spray insulation cost varies by city and project size.
Here’s an average breakdown (as of 2025):
Application | Average Cost per sq. ft. | City Example |
Roof Insulation | Rs. 400 – Rs. 600 | Lahore, Karachi |
Wall/Ceiling Insulation | Rs. 350 – Rs. 550 | Islamabad |
Cold Storage | Rs. 600 – Rs. 850 | Industrial Areas |

PU foam spray requires little to no maintenance. Once applied, it remains stable and functional for over two decades. For best results, check for UV damage on exposed surfaces every 5–7 years and reapply the protective coating if necessary.
Q1: How long does PU foam spray last?
It typically lasts 20–25 years if applied correctly.
Q2: Can PU foam spray be applied on metal roofs?
Yes, it adheres perfectly to metal, concrete, and wooden surfaces.
Q3: Does it stop water leakage?
Absolutely. It seals cracks and prevents roof leakage effectively.
Q4: Is PU foam spray safe?
Yes. Once cured, it becomes inert and non-toxic.
Q5: Can PU foam spray reduce heat in my house?
Yes, it can reduce room temperature by up to 10°C during peak summers.
PU foam spray insulation is the most reliable solution for Pakistan’s heat and leakage issues. It offers energy efficiency, durability, and comfort, making it ideal for both homes and industries.
