Jablite Insulation Board - 25mm

The R-value depends on various factors including thickness and installation. For a 25mm board, it offers good thermal resistance, contributing significantly to overall building insulation performance. Specific R-value figures should be referenced from thermal performance data if critical.

While it provides insulation, it is not a waterproofing material. In wet areas like bathrooms, it should be used in conjunction with appropriate waterproof membranes and tiling backer boards to prevent moisture ingress.

Check with your local waste disposal services for guidelines on recycling or disposing of polystyrene foam. Some local facilities may accept clean polystyrene for recycling.

Polystyrene insulation materials typically have specific fire ratings. Consult the product's technical data sheet or manufacturer for detailed fire performance information and compliance.

Yes, the white surface can be painted. Use emulsion paints and avoid solvent-based paints, which can damage the polystyrene. Ensure the surface is clean before painting.

The U-value reduction depends on the existing construction and the total insulation thickness. Adding this 25mm board will improve the U-value of the element it is applied to, reducing heat loss.

Use a fine-toothed saw or a specialized insulation knife. Ensure the blade is sharp and cut with a steady motion. Score the board first for a cleaner initial cut.

Re-measure and re-cut boards for a precise fit. Use a suitable expanding foam or sealant to fill small remaining gaps after installation.

Ensure both the board surface and the substrate are clean, dry, and free from dust or debris. Use an adhesive specifically recommended for polystyrene insulation.
