FRP Louvers
Corrosion-proof ventilation louvers with insect screen
Muwi FRP louvers are built from pultruded glass-fibre reinforced plastic profiles: C-channel top and bottom frames, rectangular-tube posts and crossbeams, Z-section blades and flat retaining strips for the insect screen, all fixed with 304 stainless steel rivets and finished with a transparent anti-corrosion coating. FRP has a quarter of the density of mild steel and is about a third lighter than aluminium, yet its tensile strength matches mild steel and its strength-to-weight ratio is 4 to 5 times higher. It does not rust or corrode, resists acids, alkalis, salt spray and seawater, insulates against heat (thermal conductivity 0.35 to 0.47 W/m·K, a fraction of metal) and electricity, and keeps its shape under wind and sustained load. With an outdoor service life of 20 to 30+ years and little or no maintenance, FRP louvers are recommended for coastal areas with high salt spray, chemical plants, electroplating workshops, wastewater treatment plants and other corrosive environments.
- About 75% lighter than mild steel, 30% lighter than aluminium
- Strength-to-weight ratio 4 to 5 times that of steel
- Non-rusting, non-corroding, non-conductive
- 20 to 30+ year outdoor service life, virtually maintenance free
- Insect screen included
