Robust XPS Sheet (Jumbolon) is a high-performance thermal insulation board made from extruded polystyrene (XPS), designed to meet the demanding needs of modern construction. Known for its exceptional durability, thermal resistance, and moisture protection, Jumbolon stands out as one of the most reliable and energy-efficient insulation materials available in Pakistan. Manufactured using advanced extrusion technology, each sheet is composed of a closed-cell foam structure that provides outstanding insulation properties while maintaining excellent mechanical strength and dimensional stability. With a low thermal conductivity—typically between 0.027 and 0.029 W/m·K—Robust XPS Sheets significantly reduce the rate of heat transfer through walls, roofs, and floors, making buildings cooler in summer and warmer in winter. This not only enhances indoor comfort but also reduces energy consumption by lowering the need for continuous air conditioning or heating, ultimately cutting utility costs for homeowners and commercial operators alike.
Robust XPS Jumbolon sheets are completely water-resistant, absorbing less than 0.3% water even under continuous exposure. This moisture resistance makes them ideal for humid environments, wet areas, or applications below the damp-proof course. Additionally, their high compressive strength—typically ranging from 250 to 350 kPa—allows them to withstand heavy loads, making them suitable for installation beneath concrete slabs, parking decks, terraces, and load-bearing floors. The sheets are also resistant to mold, bacteria, and chemical degradation, ensuring long-term performance without compromising structural integrity. Lightweight and easy to cut, handle, and install, Jumbolon XPS sheets offer convenience and speed during construction without requiring special tools or techniques. They are widely used in residential, commercial, and industrial buildings for insulation in roofs, exterior and interior walls, floors, cold storage units, HVAC ducts, and prefabricated panels.
In addition to thermal performance, Robust XPS Sheets offer acoustic insulation properties, contributing to a quieter indoor environment by reducing sound transmission. Environmentally, they are produced using eco-friendly processes and are free from ozone-depleting substances, making them compliant with green building standards. Their fire-retardant formulation further enhances safety by limiting flame spread in case of fire incidents. Available in various thicknesses and sizes, these sheets can be customized according to project requirements, making them a versatile and cost-effective choice for builders, architects, and insulation contractors. With a proven track record of reliability, energy efficiency, and ease of use, Robust XPS Sheet (Jumbolon) is the smart insulation solution for long-term protection, comfort, and performance in all types of construction.
