Jumbolon (XPS Board)

Jumbolon (XPS Board)

Jumbolon (XPS Board), technically called Extruded Polystyrene Board, is high-performance thermal insulation sheets designed for roofs, walls, floors, cold rooms, and building applications.

These boards offer excellent compressive strength, moisture resistance, and long-term insulation stability. Ideal for Pakistani climatic conditions, XPS boards help maintain temperature, reduce heat transfer, and lower cooling electricity costs.

XPS (Extruded Polystyrene) Boards are one of the most reliable and durable insulation materials used in Pakistan for residential, commercial, and industrial applications. Manufactured through a controlled extrusion process, XPS develops a closed-cell structure that provides strong resistance against heat, moisture, and mechanical load. This makes it a preferred choice for roofs, water-proofing systems, exterior walls, cold storage rooms, HVAC ducts, and under-floor insulation.

Our XPS boards are available in a standard sheet size of 3 ft × 6 ft and come in 1-inch, 2-inch, 3-inch, and 4-inch thicknesses, allowing customers to choose the required insulation level according to project needs. The boards deliver excellent thermal performance, helping maintain comfortable indoor temperatures even during Pakistan’s extreme summers and cold winters. By reducing heat transfer, XPS significantly cuts air-conditioning load and saves electricity bills.

Key Properties of Jumbolon (XPS Sheets)

• Closed-cell structure: Ensures high thermal resistance (R-value) and prevents moisture absorption.

• High compressive strength: Suitable for load-bearing applications such as under-tile insulation, flooring, and commercial roofing.

• Lightweight and easy to install: Can be cut, shaped, and fixed quickly without specialized tools.

• Low water absorption: Maintains performance over time, especially in humid or wet environments.

• Chemically stable: Resistant to mold, fungus, and most construction chemicals.

• Long service life: Maintains insulation efficiency for 20+ years.

Applications of Jumbolon

• Residential & commercial roof insulation

• Wall insulation for heat control

• Under-floor insulation and radiant floor systems

• Cold rooms and temperature-controlled warehouses

• HVAC duct insulation

• Prefabricated structures and portable cabins

• Thermal insulation for water-proofing systems

Manufacturing Process to Produce  XPS

• HCFC/HFC-based XPS gives better quality because it forms a denser, fully closed-cell foam.

• It also offers superior moisture resistance, higher strength, and better long-term performance.

• Due to the cost of blowing agents and specialized equipment, its price is higher, but the performance advantage makes it ideal for premium and industrial-grade applications.
