CDM Fibran XPS-500C

Fibran XPS-500C Insulation Board – High-Performance Thermal & Waterproofing Solution

The Fibran XPS-500C Insulation Board is a 50mm thick, closed-cell extruded polystyrene (XPS) board designed for superior thermal insulation and waterproofing applications. Manufactured to EN 13164 standards, it offers exceptional durability, water resistance, and high compressive strength, making it ideal for cavity drain waterproofing, external wall protection, and green roof systems.

Key Benefits:

✅ Excellent Thermal Insulation – Low thermal conductivity (0.035 W/mK) for efficient energy retention.
✅ Waterproof & Vapor-Resistant – Closed-cell structure prevents water absorption and vapor diffusion.
✅ High Compressive Strength – Rated at 500 kPa, ensuring long-term structural stability.
✅ Permanently Water-Resistant – Can be fully submerged without degradation.
✅ Long Lifespan – Estimated 50-year durability, matching the lifespan of the building.
✅ Eco-Friendly & Safe – 100% recyclable, CFC & HCFC-free, and resistant to rodents, insects, and mold.

Typical Applications:

✔ Cavity Drain Waterproofing – Used as a 50mm spacer in the Newton CDM System for drainage support.
✔ Protection for Waterproofing Membranes – Shields Newton liquid-applied waterproofing membranes on retained walls.
✔ Insulated Support for HydroBond 403 Plus – Enhances thermal and structural performance.
✔ Parking Decks & Green Roofs – Provides insulation and drainage for rooftop applications.
✔ External Insulation for Subterranean Structures – Ideal for buildings within the water table.

Suitable Substrates:

✔ Compacted, clean, and level surfaces
✔ Basement concrete floor slabs and rafts
✔ Earth-retained concrete walls, mortar, or ICF
✔ Compacted blinding layers
