Pakistani summers push rooftop slabs past 60°C, turning top floors into ovens and sending AC bills soaring from May to September. Roof heat insulation — professionally called heat proofing — is the single most effective retrofit for cutting indoor heat. For the best roof heat insulation in Pakistan, Thermo Master — a top insulation manufacturer — designs and installs roof heat insulation systems across Pakistan from our factory on Katar Band Road, near Thokar Niaz Baig, Lahore, with 500+ completed projects since 2017.
We work with thermopore (EPS) sheets, jumbolon (XPS foam) and PU spray foam — recommending the right system for your roof type and budget rather than selling one product for every job.
How Roof Heat Insulation Works
Heat reaches rooms by conduction through the slab: the sun bakes the roof, and heat migrates downward for hours, peaking indoors in late afternoon. Insulation on top of the slab intercepts this flow — every system is an insulation layer, sealed joints and protective covering, differing only in material and thickness.
A well-designed system cuts ceiling surface temperature by 8–15°C on peak days — top-floor rooms become livable without round-the-clock AC, and electricity bills drop noticeably through the cooling season.
Insulation Systems Compared
| System | Build-up | Heat Reduction | Indicative Cost | Best For |
|---|---|---|---|---|
| Thermopore + screed | 1.5″–2″ EPS under 1″–1.5″ screed | High | Rs. 180–320/sq ft installed | Budget-friendly, flat concrete roofs |
| Jumbolon + screed/tiles | 10–15 mm XPS under screed | Medium–High | Rs. 150–280/sq ft installed | Thin build-up, moderate budgets |
| PU spray foam + coating | 1″–1.5″ spray + UV topcoat | Very High | Rs. 130–220/sq ft installed | Premium, irregular roofs, fast install |
| Reflective coating only | Elastomeric white coating | Low–Medium | Rs. 80–150/sq ft installed | Mild heat, tight budgets |
| Insulation + waterproofing combo | EPS/PU + membrane system | High | Quoted per survey | Roofs that also leak |
Installed prices are indicative and include material and labour for typical Lahore roofs; they vary with roof condition, area and access.
Which System Suits Your Roof?
- Sound concrete roof, tight budget: thermopore + screed — maximum insulation per rupee
- Roof level cannot rise much: jumbolon or PU foam — thin build-up
- Old, cracked, uneven roof: PU spray foam — seamless, conforms to every irregularity
- Roof also leaks: combined insulation + waterproofing package — one mobilisation, both problems solved
- Metal or corrugated shed: foil-faced jumbolon or PU spray — flexible, follows the profile
Applications Across Pakistan
- Homes — top-floor bedrooms and lounges in Lahore, Karachi, Islamabad, Multan, Faisalabad, Peshawar
- Apartments — top-floor flats where the roof is the biggest heat source
- Offices and plazas — staff comfort and lower cooling costs
- Schools and hospitals — comfortable interiors without massive AC bills
- Factories and warehouses — worker productivity and product protection
- Poultry farms — temperature control directly affects bird performance
- Marquees and halls — event comfort in summer wedding season
Poultry Shed & Poultry Farm Insulation
Poultry shed insulation is one of the highest-ROI insulation jobs in Pakistan: birds under heat stress eat less, grow slower and lay fewer eggs, while a well-insulated poultry farm holds a steadier temperature with less ventilation load. We insulate poultry sheds with thermopore sheets under the roof, jumbolon over metal sheets, or PU spray foam for sealed controlled-environment houses — matched to open, semi-controlled or fully controlled poultry farm designs.
Price Table: Best Roof Heat Insulation Rates in Pakistan
| Insulation System | Indicative Price Range | Best For |
|---|---|---|
| Thermopore (EPS) system | Rs. 180–320 per sq ft | Budget-friendly full roofs |
| Jumbolon (XPS) system | Rs. 150–280 per sq ft | Thin, lightweight application |
| PU spray foam system | Rs. 130–220 per sq ft | Maximum insulation, uneven roofs |
| Reflective coating | Rs. 80–150 per sq ft | Supplementary heat reflection |
| Combined insulation + waterproofing | Quoted per survey | Roofs needing both solutions |
All prices are indicative per sq ft installed, quoted after a free site survey — roof condition, area and detailing affect the final figure. Material-only supply for contractors costs significantly less. Confirm current rates on WhatsApp or call 0333-4673836.
Installation Notes: What a Proper Job Looks Like
1. Roof cleaned, loose material removed, cracks repaired, drainage checked 2. Insulation laid with tight butt joints; gaps sealed 3. Protective layer applied — screed, tiles or UV coating per system 4. Parapet junctions and pipe penetrations detailed so heat cannot bypass the system
A proper residential job takes 3–7 days. Beware one-day “heat proofing” offers — invariably a single coat of ordinary paint, which does almost nothing.
Common Mistakes to Avoid
- Insulating a leaking roof without fixing the leak — trapped moisture destroys the system from below
- Leaving insulation exposed to sun — UV degrades EPS and PU foam within a season or two
- Ignoring parapet and pipe penetrations — heat bypasses insulation at every unsealed edge
- Choosing on price alone — the cheapest option often needs replacing twice as soon
Maintenance Tips
Keep roof drains clear — standing water is the enemy of every insulation system. Inspect the screed or coating yearly before summer and touch up cracks promptly. With basic care, expect 10–20 years of service.

FAQs
How much will roof insulation reduce my electricity bill? Clients typically report 20–40% lower summer cooling costs for top-floor zones. Payback for a thermopore system is commonly 2–4 cooling seasons.
Can insulation be installed on an old roof? Yes, if structurally sound — cracks and minor damage are repaired during preparation. Our free survey confirms suitability before quoting.
Will insulation make the roof usable as a terrace? Yes — with a screed or tile finish over the insulation, the roof stays fully walkable. Ask for a traffic-rated build-up.
How long does installation take? A typical 1,000–2,000 sq ft residential roof takes 3–7 working days including curing. PU spray foam is fastest.
Does roof insulation help in winter? Yes, modestly — the same barrier slows heat loss on cold nights, noticeable in Islamabad, Peshawar and Quetta winters.
Is roof insulation worth it for a poultry farm? Usually yes — poultry farm insulation pays back fast because heat stress directly cuts bird weight gain and egg production. Insulating the shed roof with thermopore or jumbolon keeps indoor temperatures steadier, so fans and foggers work less and mortality drops in peak summer.
Do you provide material-only supply for contractors? Yes — contractors across Pakistan buy sheets, jumbolon and PU materials at dealer rates. Ask about contractor pricing.
