PU foam is created on site by mixing two liquid components that react and expand into a rigid closed-cell foam. Sprayed onto the roof, it bonds to concrete or metal, fills gaps and cracks, and forms a continuous insulating layer without joints.
Why PU foam is effective
- Very low thermal conductivity, so a thin layer insulates well
- Closed-cell structure that resists water
- Seamless, so no gaps for heat or water
- Lightweight, adding little load to the roof
- Strong adhesion to most surfaces
Protecting the foam
PU foam degrades in sunlight, so it must be covered with a UV-stable protective coating, usually a white reflective elastomeric or polyurethane top coat. This also adds reflectivity, so the system both reflects and insulates.

Why roofs in Pakistan get so hot
For several months each year, much of Pakistan faces intense sun and high temperatures. In Punjab, Sindh, southern Khyber Pakhtunkhwa and Balochistan, a flat concrete roof can become too hot to touch by early afternoon. Concrete is a heavy material that stores heat. It absorbs sunlight all day and keeps releasing that heat into the rooms below well into the night, which is why top floor rooms stay hot long after sunset.
Dark surfaces such as old bitumen absorb even more heat. Thin modern roofs without the old mud layers let heat pass through faster. The result is uncomfortable top floors, fans that only move hot air, air conditioners that run for hours and electricity bills that climb every summer. Load shedding makes the problem worse, because when cooling stops, rooms under a hot roof heat up quickly.
How we carry out pu foam roof insulation
The roof is cleaned, dried and primed. Edges, drains and equipment are masked. Foam is sprayed in passes to build the required thickness, with slopes maintained towards drains. Once cured, the surface is inspected and the UV-stable reflective top coat is applied in two coats. Our trained applicators use proper protective equipment and work in suitable weather.

How heat proofing reduces indoor temperature
Heat moves from a hot roof into a building in three ways, and good heat proofing addresses each one.
Absorption of sunlight
Dark surfaces absorb most of the sunlight that hits them. White and reflective surfaces bounce much of it back. A high-reflectance coating keeps the roof surface far cooler.
Conduction through the slab
Heat travels through solid concrete from the hot top surface to the ceiling below. Insulation slows this flow, keeping more heat out.
Radiation from the ceiling
A hot ceiling radiates heat into the room, which you feel even when the air temperature is not extreme. A cooler slab means a cooler ceiling and a more comfortable room.
Reflective coatings deal mainly with absorption, insulation deals with conduction, and together they reduce ceiling temperature and radiant heat.
Heat proofing for different parts of Pakistan
The hottest roofs we treat are in southern Punjab and upper Sindh, in cities such as Multan, Bahawalpur, Rahim Yar Khan, Dera Ghazi Khan, Sukkur, Larkana and Jacobabad, where summer heat is extreme and lasts for months. Here we usually combine reflective coatings with insulation. In Lahore, Faisalabad, Gujranwala and Sialkot, heat and heavy monsoon rain both matter, so we choose reflective coatings that are also fully waterproof. In Karachi and coastal areas, humidity and salt air call for durable, mould-resistant finishes. In Islamabad, Rawalpindi, Peshawar and Quetta, insulation also helps keep homes warmer in winter, giving a benefit all year.

Our heat proofing process
1. Free inspection
We check the roof surface, existing layers, cracks, leaks and drainage, and ask how hot the top floor gets.
2. Recommendation and quote
We explain the options and give a written quote with area, materials, timeline and warranty.
3. Leak repair first
If the roof leaks, we fix it first, because heat proofing over a leak traps water.
4. Surface preparation
The roof is cleaned, loose material removed, cracks repaired and primer applied.
5. Application
Coatings are applied in multiple coats to the right thickness, or insulation is installed and protected.
6. Finishing and handover
Parapets, edges and details are finished neatly and the site is cleaned.
“Any white paint works”
Ordinary paint chalks, cracks and loses reflectivity on a hot roof. Proper reflective roof coatings are elastic, UV-stable and often waterproof.
“A thick mud layer is best”
Mud insulates but adds heavy weight, holds water and breaks down over time. Modern insulation is lighter and more effective.
“Heat proofing is only for summer”
Insulation also reduces heat loss in winter.
“It does not matter if the roof leaks”
Heat proofing over a leaking roof traps water. Leaks must be repaired first.

Benefits you will notice
- Cooler top floor rooms, especially in the afternoon and evening
- Lower electricity bills as air conditioners and fans work less
- More comfort during load shedding
- Longer roof life because the slab expands and contracts less
- Leak protection with waterproof reflective coatings
- A more usable roof in summer evenings
Combining heat proofing with waterproofing
Most roofs need protection from both heat and rain. Doing both in one project saves money, because surface preparation is done once, and gives better results, because reflective layers protect the waterproofing membrane from UV and heat ageing. A typical combined system is a waterproof membrane with a reflective top coat, or insulation over a membrane protected by screed. See roof waterproofing and roof membrane waterproofing.
- Rinse the roof occasionally to remove dust, which lowers reflectivity
- Keep outlets clear so water does not pond
- Avoid heavy traffic on coatings, or ask for a traffic-grade finish
- Recoat every few years to restore reflectivity
- Check after storms and call us early if you see damage
PU Foam Roof Insulation for homes, businesses and industry
We provide pu foam roof insulation for family homes, apartment buildings, offices, schools, hospitals, mosques, shops, factories and warehouses. Homes benefit from cooler bedrooms and lower bills. Schools and offices gain more comfortable classrooms and workspaces. Factories and warehouses protect workers and stock from extreme heat. Every project is planned around how the building is used, with work scheduled to cause minimum disruption.
Signs your roof needs heat treatment
- Top floor rooms are much hotter than the rest of the house
- Ceilings feel warm to the touch in the evening
- Rooms stay hot for hours after sunset
- Air conditioners on the top floor run constantly
- Electricity bills jump in summer
- The roof surface is too hot to walk on in the afternoon
- Old roof layers are cracked and brittle from the sun
If several of these sound familiar, your roof is absorbing and passing on too much heat, and treatment will make a clear difference.
Heat proofing options compared
| Option | How it works | Best for |
|---|---|---|
| Reflective elastomeric coating | Reflects sunlight, waterproof | Most homes, fast improvement |
| Heat-resistant coating | High reflectance and emittance | Very hot exposed roofs |
| PU foam insulation | Seamless insulation, seals leaks | Very hot top floors, sheds |
| Insulation boards | Slows heat flow under screed | Roofs being re-finished |
| Thermal insulation coating | Thin coating with insulating fillers | Walls, tanks, metal |
| Cool roof system | Complete reflective system | Homes, schools, offices |
We recommend the right option after measuring the roof and understanding how hot your rooms get.
Heat proofing and your electricity bill
On many Pakistani homes, the top floor air conditioner is the single biggest user of electricity in summer. When the roof is hot, the ceiling keeps radiating heat into the room, and the air conditioner has to work continuously to remove it. By reducing the heat entering through the roof, heat proofing lets air conditioners reach the set temperature faster and cycle off more often. Fans become more effective, and rooms stay comfortable for longer during load shedding. The exact savings depend on the house, the system chosen and how you use cooling, but most families find the investment pays back steadily over the summers that follow.

Questions about PU Foam Roof Insulation
Answers to the questions customers ask us most about pu foam roof insulation.
0321-4156036
How thick should PU foam be?
It depends on the heat reduction needed. We recommend a thickness after the survey.
Does PU foam need a top coat?
Yes, a UV-stable coating protects it from sunlight.
Is PU foam waterproof?
The closed-cell foam resists water, and the top coat adds a waterproof finish.
Can it be applied on metal roofs?
Yes, it bonds well to metal sheets and seals laps and screws.
Is heat proofing worth the cost?
For most homes with hot top floors, yes. Cooler rooms, better sleep and lower cooling bills over several summers usually justify the investment.
Can heat proofing be done on a new house?
Yes, and it is ideal. Insulation and reflective finishes can be planned into the roof build-up during construction at lower cost.
Will a white roof get dirty?
Dust settles on any roof. Rinsing occasionally keeps it reflective, and recoating every few years restores the bright finish.
Does heat proofing work on sloped or domed roofs?
Yes. Coatings follow any shape, including domes and sloped slabs.
Is the coating safe for my family?
Yes. We use water-based or low-odour products where possible and keep work areas ventilated.
Can I use the roof straight after treatment?
Light use is usually possible after a day or two once the coating has cured. We will tell you the exact time for your system.
Does heat proofing affect solar panels?
No. We work around panel stands, and a cooler roof can even help panels run a little cooler.
Do you heat proof water tanks?
Yes. Reflective coatings on tanks help keep stored water cooler in summer.
Do you provide a written warranty?
Yes. Complete systems come with a written warranty. The period depends on the system and is stated clearly in your quote.
