Insulation Polystyrene Block MEGA 500×140 mm model 61605

MEGA insulation polystyrene block sized 500×140 mm is a rigid expanded polystyrene (EPS) element designed for thermal insulation and lightweight construction tasks. The MEGA 500×140 mm model 61605 provides a compact, low-weight solution for filling cavities, insulating walls, floors or roofs, and for use in packaging or as a spacer within building assemblies. The block's format and material make it easy to cut, shape and fit into irregular spaces where standard panels are impractical.

Advantages

The EPS construction offers low thermal conductivity and high compressive strength relative to its weight, ensuring thermal performance without significant added mass. Its rigid form factor supports simple handling and rapid on-site modification with common cutting tools. The material resists moisture absorption under normal conditions and contributes to reduced thermal bridging when used as infill or spacer. The block's consistent dimensions simplify planning and installation in a range of applications.

Suitable for

• Filling cavities in walls, floors and roof structures
• Lightweight thermal insulation of non-structural elements
• Packaging of fragile or shaped items requiring shock absorption
• Use as spacers or formwork inserts in building assemblies

Key specifications

• Material: Expanded polystyrene (EPS)
• Dimensions: 500 × 140 mm
• Form: Rigid rectangular block
• Typical properties: Low thermal conductivity and lightweight construction
• Workability: Can be cut, shaped and trimmed with hand or power tools

How to use

Measure the cavity or area to be insulated and mark the block for cutting to ensure a snug fit. Use a straightedge and a suitable cutting tool (hot-wire cutter, serrated knife or saw) to trim the block to the required shape and dimensions. Place the trimmed block into the prepared space, ensuring contact with adjacent insulation or structural elements to minimize gaps. For fixed installations, secure with compatible adhesives, mechanical fasteners or by embedding in mortar or plaster according to the surrounding assembly requirements. When used for packaging, position the block to support and protect the product, trimming as necessary for a precise fit.

Usage recommendations

Store the blocks flat in a dry, shaded area away from direct sunlight and heat sources. Avoid contact with solvents, petroleum-based products and open flame. Use appropriate personal protective equipment when cutting (gloves, eye protection and a dust mask) and follow local building codes and insulation standards for thermal performance and fire safety.
