Fiberglass reinforcement (also written as fibreglass or GFRP reinforcement) is a non-corrosive alternative to reinforcing steel and bed joint reinforcement, made from alkali-resistant (AR) glass fibre. GRID Glass, FLEX GRID AR-glas and BRIKSY AR-glas are the products designed for concrete and masonry reinforcement with glass fibre.
Fiberglass reinforcement consists of alkali-resistant (AR) glass fibres that, like reinforcing steel or bed joint reinforcement, absorb the tensile forces in concrete or masonry. Because glass fibre does not corrode, the reinforcement stays intact when exposed to moisture, unlike steel which can rust and cause cracking. Note that this is a different application from fibreglass mesh for render or plaster; for that, see Primafas for ETICS systems.
GRID Glass is a high-strength, lightweight, corrosion-resistant glass fibre reinforcement grid for load-bearing concrete structures. FLEX GRID AR-glas is a flexible mesh for walls, facades and floors. BRIKSY AR-glas is bed joint reinforcement for masonry, available in 6 widths from 40 to 300 mm.
| Product | Application | Feature |
|---|---|---|
| GRID Glass | Load-bearing concrete structures | High-strength, lightweight, corrosion-resistant |
| FLEX GRID AR-glas | Walls, facades, floors | Flexible, cut to size |
| BRIKSY AR-glas | Bed joint reinforcement for masonry | 6 widths, 40-300 mm, 860 g/m² |
GRID Glass and FLEX GRID AR-glas are placed as reinforcement mesh in the formwork or on the substrate, BRIKSY AR-glas is placed in the bed joint of the masonry. The exact overlap, fixing and layer thickness are given on the technical data sheet of the chosen product.
BRIKSY AR-glas is CE marked in accordance with EAD 260057-00-0303. The design values and application limits of GRID Glass and FLEX GRID AR-glas are given on the technical data sheet of the chosen product.
No. This page covers fiberglass reinforcement for concrete and masonry (GRID Glass, FLEX GRID AR-glas, BRIKSY AR-glas). For render or ETICS mesh, Primafas is the suitable product.
Glass fibre is more cost-effective than carbon and basalt at a somewhat lower tensile strength. Carbon offers the highest tensile strength, basalt a heat-resistant alternative.
Load-bearing concrete structures (GRID Glass), walls, facades and floors (FLEX GRID AR-glas) and masonry (BRIKSY AR-glas).
No, glass fibre is non-metallic and does not corrode, unlike steel reinforcement.
