GLAPOR SG600 Recycled Foam Glass Insulating Gravel
GLAPOR SG600 is a lightweight insulating gravel manufactured from 100% recycled foamed glass. Designed as a load-bearing insulation layer and lightweight fill material, it combines thermal insulation, drainage, frost protection, and structural performance within a single product.
Its closed-cell structure makes it waterproof, non-combustible, rot-proof, and dimensionally stable, making it suitable for floor slabs, foundation insulation, limecrete floors, renovations, and civil engineering applications.

Key Benefits
Thermal Insulation & Structural Fill
Provides both insulation and load-bearing performance, helping simplify floor and foundation build-ups.
Lightweight
The low bulk density reduces loading compared to conventional hardcore and aggregate materials.
Waterproof & Frost Resistant
The closed-cell glass structure does not absorb moisture and retains its insulating properties over time.
Capillary Breaking
Helps prevent capillary moisture movement through the floor construction while maintaining drainage performance.
Non-Combustible
Manufactured from recycled glass and classified as A1 non-combustible.
Sustainable Construction
Produced from 100% recycled glass and fully recyclable at the end of its service life.

Why Use GLAPOR SG600?
GLAPOR SG600 combines insulation, drainage, frost protection, and structural support within a single material. Unlike traditional hardcore, it contributes to the thermal performance of the building while remaining lightweight and load-bearing.
Its waterproof closed-cell structure means the insulation performance remains stable over time, making it particularly suitable for floor slab construction, limecrete systems, foundation insulation, and sustainable building projects.
Installation Overview
1. Ground Preparation
Ensure the formation level is stable, level, and suitable for installation.
2. Placement
Spread the gravel evenly to the specified depth.
3. Compaction
Compact in accordance with the project specification and GLAPOR installation guidance.
4. Levelling Layer
Install the specified levelling or separation layer where required.
5. Floor Construction
Complete the floor build-up with limecrete, concrete, screed, or other specified floor systems.
