Insulation Polystyrene Block MEGA 280×140 mm model 61602

Polystyrene insulation block MEGA 280×140 mm model 61602 is a rigid expanded polystyrene element intended for thermal insulation, cavity filling and lightweight construction tasks. The block's rectangular shape and consistent dimensions make it suitable for on-site adjustments; it can be cut, shaped and fitted with common hand tools to meet installation requirements. Designed for use where rigid polystyrene panels or blocks are required, this MEGA block provides a low-weight, easy-to-handle solution for both construction and packaging applications.

Advantages

This MEGA polystyrene block combines low thermal conductivity with a stable, closed-cell structure that resists moisture uptake and provides effective cavity filling. Its uniform dimensions and smooth surfaces simplify cutting and installation, reducing on-site labour time. The product's light weight eases handling and transport, and it is compatible with adhesives and common fixings used in construction and packaging. Overall, the block offers predictable performance for insulation and lightweight construction tasks.

Suitable for

• Thermal insulation of small cavities and gaps
• Filling voids in lightweight construction and partition systems
• Protective packaging and cushioning for fragile items
• Model making, crafts and DIY applications requiring rigid foam

Key specifications

• Material: expanded polystyrene (rigid EPS)
• Dimensions: 280 × 140 mm
• Form: rectangular block suitable for cutting and shaping
• Weight: lightweight for easy handling
• Surface: smooth faces for adhesion and finishing

How to use

Measure and mark the block to the required dimensions and cut with a fine-toothed saw, hot wire cutter or a sharp utility knife, depending on the desired finish. Fit the block into the cavity or position in the assembly, ensuring a snug but not overly tight fit. Use construction adhesives, foam-compatible glue or mechanical fixings as appropriate for the application and substrate. For thermal insulation applications, seal joints between blocks with compatible tape or sealant to minimise convective heat loss.

Usage recommendations

Avoid exposing the polystyrene block to open flame or high-temperature sources. Store flat in a dry, shaded area and protect from prolonged sunlight to prevent surface degradation. When cutting, wear appropriate eye and hand protection and perform work in a well-ventilated area to reduce dust. For exterior insulation applications, combine with appropriate protective layers and finishes to ensure durability and weather resistance.
