FAQs
What is the R-value of this 50mm board?
The R-value depends on specific testing, but a 50mm polystyrene board typically offers good thermal resistance, contributing significantly to a building's insulation.
Can I use this insulation board outdoors?
This board is designed for internal insulation applications within walls, floors, and roofs. It should be protected from direct weather exposure and UV light.
Is this board suitable for use in a bathroom?
Yes, it can be used in bathrooms as part of an insulated wall or floor structure, but it must be properly sealed and protected by moisture-resistant finishes like tiles.
How do I dispose of offcuts?
Offcuts can often be recycled with rigid polystyrene waste. Check with your local waste disposal services for specific recycling guidelines.
What is the fire rating of polystyrene insulation?
Polystyrene is combustible. Depending on building regulations and the application, it may require a fire-retardant treatment or specific protective coverings.
Do I need a vapor barrier with this insulation?
The need for a vapor barrier depends on the climate, building construction, and the position of the insulation. Consult local building codes and best practices for your specific project.
Can I glue directly onto this board?
You can glue directly onto the board using adhesives compatible with polystyrene. For finishes like plaster, it's generally recommended to fix a substrate such as plasterboard first.
Troubleshooting
Boards difficult to cut cleanly
Use a very sharp utility knife or consider a specialized polystyrene hot wire cutter for precise edges.
Gaps between boards
Trim boards for a snug fit. Use expanding foam or a suitable filler to seal any remaining small gaps after installation.
Adhesive not bonding well
Ensure surfaces are clean, dry, and free from dust. Use an adhesive specifically recommended for polystyrene insulation.
Boards bowing or deforming
Ensure boards are adequately supported and fixed according to installation guidelines. Avoid excessive moisture during storage or installation.

Setup, Compatibility & Care
Installation:
- Measure and Cut: Accurately measure the required areas. Cut the Jablite boards using a sharp utility knife or a hot wire cutter for cleaner edges.
- Fit: Ensure a snug fit within studwork, joists, or desired spaces. Minimize gaps between boards and surrounding structures.
- Fixing: Secure boards using appropriate mechanical fixings (e.g., plasterboard screws with large washers for walls) or suitable insulation adhesives. Follow manufacturer guidelines for fixing density.
- Finishing: Cover with plasterboard, wood panelling, or other suitable finishing materials as required by the application and building regulations.
Compatibility:
The Jablite Insulation Board is compatible with most standard construction materials, including timber, metal framing, concrete, and masonry. Ensure all adhesives and fixing systems are compatible with polystyrene.
Care:
- Store boards flat in a dry location, away from direct sunlight and heat sources.
- Keep packaging intact until ready for use to protect from damage and moisture.
- Clean any dirt or debris with a dry cloth or brush. Avoid using solvents or harsh chemicals which can damage the polystyrene.
