Jumbolon sheet XPS insulation ki pink sheet hai — patli, halki aur moisture-resistant, jo chhat, deewar, car roof aur metal roof ki heat proofing ke liye istemal hoti hai. Thermo Master ise Lahore factory (Katar Band Road, near Thokar Niaz Baig) se poore Pakistan me supply karta hai; 1 inch sheet ~1.6 kg aur 2 inch ~2.7 kg hoti hai.
Jumbolon XPS insulation sheets — rigid extruded polystyrene boards in pink and blue — are one of Pakistan’s most effective insulation materials for roof heat proofing, wall insulation and cold storage. For the best jumbolon sheet in Pakistan, Thermo Master — a top XPS manufacturer — produces and supplies it from our factory on Katar Band Road, near Thokar Niaz Baig, Lahore, delivering across Pakistan since 2017.
Unlike flexible foam rolls, jumbolon XPS comes as rigid boards with a dense, closed-cell structure — 95% closed cells — that blocks conducted heat, resists compression under screeds and flooring, and absorbs almost no water. That is why engineers specify XPS boards under concrete roof screeds, inside wall cavities, under floors and in freezer rooms where ordinary insulation fails.
What Jumbolon (XPS) Is and How It Works
Jumbolon is extruded polystyrene (XPS) — polystyrene melted and extruded into rigid boards with a fine, uniform closed-cell structure. The extrusion process gives XPS its signature traits: high compressive strength (210–700 kPa depending on density), very low thermal conductivity (0.025 W/mK), and near-zero water absorption. Boards are supplied with butt, shiplap or tongue & groove edges so joints lock tight with no heat bridges.
Each 1-inch (25 mm) board delivers an R-value of 5.88 — roughly twice the insulation of the same thickness of ordinary thermopore (EPS). For a concrete roof in Lahore or Karachi, 2 inches of XPS under a screed cuts heat transfer dramatically and keeps top-floor rooms noticeably cooler all summer.

Jumbolon (XPS) vs Thermopore (EPS) — Which Should You Pick?
| Factor | Jumbolon (XPS) | Thermopore (EPS) |
|---|---|---|
| Structure | Rigid extruded board, 95% closed cell | Rigid expanded beads board |
| Compressive strength | 210–700 kPa — walks on, takes screed load | Lower — needs protection |
| Water absorption | Near zero | Low, but higher than XPS |
| Insulation per inch | R-5.88 per inch — higher | Lower per inch |
| Best for | Roofs under screed, walls, cold storage, floors | Light roofs, walls, packaging |
| Cost | Higher per board | Budget-friendly |
Applications in Pakistan
- Roof heat insulation — boards laid under a cement screed or tiles on concrete roofs; the standard specification for top floors in Lahore, Karachi and Islamabad
- External wall insulation — fixed to outer walls before plaster/cladding for cooler interiors
- Cavity wall insulation — boards placed inside double-brick wall cavities during construction
- Cold storage & freezer rooms — 2″–5″ boards for walls, ceilings and floors of cold rooms
- Floor & foundation insulation — high-compressive boards under floor slabs
- Poultry & metal shed roofs — rigid boards over purlins under metal sheets cut radiant heat into sheds and poultry farms

Installation Notes
For roofs, lay boards butt-jointed or shiplap over a cleaned, levelled slab with staggered joints, then cover with a 1–1.5″ cement screed or tiles — never leave XPS exposed to direct sun long-term, as UV degrades the surface. For walls, fix boards with adhesive and mechanical anchors before plastering. For cold rooms, seal all joints with compatible tape to maintain the vapour barrier. Boards cut cleanly with a fine saw or hot wire. Avoid laying on uneven slabs (boards can rock and crack under load) and never use low-density boards where heavy loads are expected.

FAQs
What is the difference between jumbolon (XPS) and thermopore (EPS)? Both are polystyrene, but jumbolon is extruded (XPS) — a denser, stronger board with 95% closed cells, 0.025 W/mK conductivity and 210–700 kPa compressive strength. Thermopore (EPS) is expanded bead board — lighter and cheaper, but weaker and less insulating per inch.
Which thickness of jumbolon is best for a home roof in Pakistan? 1.5″–2″ under a screed suits most homes; 1″ works for walls. Cold storage rooms typically need 3″–5″.
Do you supply jumbolon sheets up to 5 inches thick? Yes. We manufacture jumbolon (XPS) sheets from 1 inch up to 5 inches (125 mm) thick. Boards above 2″ are made to order — send your thickness and quantity on WhatsApp at 0333-4673836 for a factory quote.
How much does a jumbolon sheet weigh? Indicative factory-scale weights: a 1″ board is about 1.6 kg and a 2″ board about 2.7 kg. Weight varies with board size and density.
Is jumbolon waterproof? XPS absorbs almost no water, but it is insulation, not a waterproofing membrane — fix roof leaks before insulating.
Can jumbolon be used for cold storage? Yes — it is the preferred board for cold rooms and freezer rooms: 2″–5″ thickness, sealed joints, high compressive strength for floor use.
Do you deliver outside Lahore? Yes. We supply XPS boards across Pakistan including Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, Quetta, Sialkot and Gujranwala. Transport is arranged via goods transporters; cost depends on volume and destination.
