Penová doska EFB Elektronik 698031

EFB Elektronik 698031 foam board is a rigid insulation panel designed for thermal insulation tasks in construction and DIY projects. The board has a thickness of 4 cm, a width of 520 mm and a length of 750 mm, combining effective thermal resistance with a lightweight structure that simplifies transport and handling. Manufactured for consistent dimensional stability, this foam board is suitable where a compact, easy-to-fit insulation layer is required.

Advantages

The foam board delivers reliable thermal insulation with low weight, allowing faster installation and reduced structural load. Its rigid core provides good compressive strength for non-structural insulating layers and maintains shape over time, helping to reduce thermal bridges. The smooth surfaces facilitate cutting to size and integration with other building materials.

Suitable for

• Wall insulation in renovation and new-build projects
• Insulation under flooring or raised floors
• Roof and attic insulation where rigid panels are required
• Thermal separation of partitions and service ducts

Key specifications

• Panel thickness: 4 cm
• Width: 520 mm
• Length: 750 mm
• Rigid foam construction for dimensional stability
• Lightweight design for easier handling and installation

How to use

Measure the area to be insulated and cut the foam board to the required dimensions using a fine-toothed saw or insulation knife. Fit panels tightly against adjacent boards and building elements to minimise gaps; use compatible adhesives or mechanical fixings appropriate for the substrate to secure the panels. Seal joints and edges with suitable tape or sealant to improve thermal performance and prevent air infiltration. Follow local building codes and manufacturer guidelines for layering, vapour barriers and fire safety where applicable.

Recommendations

Store panels flat in a dry, covered area to avoid moisture absorption. Protect from direct sunlight and sources of heat during storage and installation. For best results, combine with complementary insulation materials and ensure proper sealing of joints to maintain continuous thermal performance.
