Why XPS Jamblone Sheet Is the Best Heatproofing & Insulation Solution

XPS (Extruded Polystyrene) is manufactured using an advanced extrusion process, giving it a uniform closed-cell structure that prevents water absorption and ensures consistent insulation performance. Unlike EPS sheets, thermocol, or basic foam sheets, XPS offers superior mechanical strength, improved durability, and much better thermal resistance. Builders prefer XPS Jamblone Sheets for projects requiring long-lasting insulation because it does not deform, break, or absorb moisture over time.

One of the biggest advantages of XPS insulation is that it provides uniform thermal resistance across the entire sheet, which guarantees stable cooling. The low thermal conductivity (K-value) ensures that heat does not enter the building easily. During summer, this reduces indoor heat and cuts air-conditioning costs by up to 35–40%. During winter, the insulation also helps retain warmth inside the rooms, reducing heating costs.

For technical details used by engineers, many refer to thermalinsulationguide.com/xps-properties where the foundational characteristics of XPS insulation are explained in depth.

XPS Jamblone Sheet as a Roof Heatproofing Solution

RCC roofs absorb high amounts of heat because concrete acts as a heat conductor. In Pakistan’s summer temperatures, roofs become extremely hot, reaching up to 60–70°C under direct sunlight. This heat transfers into the rooms below, causing discomfort and excessive use of air conditioners.

Using a High-Performance XPS Jamblone Sheet on the roof provides:

Instant reduction in heat absorption
Long-term cooling performance
Significant energy savings
Protection against roof cracks due to thermal expansion
Moisture barrier to prevent dampness and seepage

Most contractors recommend placing the XPS sheet beneath the screed layer for maximum benefit. This method is widely used in residential houses, commercial plazas, and large industrial buildings.
