The Dickson SLF Premium Range is manufactured by Saint Clair Textiles, a member of the Dickson Group. These high-performance architectural membranes are engineered for demanding outdoor structures where durability, dimensional stability, flame safety, and long-term surface protection are important.
Each membrane is built with an 1100 dTex high-tenacity polyester support cloth, PVC Lowick coating technology, and a PVDF finish on both sides. This combination helps protect the fabric from moisture penetration, mold formation, dirt buildup, pollution, and weather-related wear while maintaining a clean architectural appearance.
The Lowick system helps seal the internal polyester yarns against moisture penetration, reducing the risk of mold, delamination, and dark stains caused by inner wicking.
Both sides are finished with a Cleangard PVDF lacquer coating, helping the surface resist soot, dust, organic debris, and pollution while making cleaning easier.
Designed for large-span and high-tension structures, with strong tensile capacity, tear resistance, and low residual deformation under load.
The SLF range can be welded directly on both sides using high-frequency or hot-air welding without prior mechanical grinding or chemical stripping of the lacquer.
The range includes certified flame-retardant performance including M2, B1, BS 7837, EN 13501-1 B-s2-d0, and NFPA 701 certified pass.

The membrane range is rated M2, B1, BS 7837, EN 13501-1 B-s2-d0, and NFPA 701 compliant/certified pass. For the opaque white option, solar reflection is listed at 78%, solar absorption at 8%, and translucency at approximately 12%, while the blackout variant has 0% translucency.
The SLF range is suitable for hot-air and high-frequency welding. To protect the PVDF surface, avoid dragging the membrane over rough ground or steel cables during installation. Use ground canvases or smooth tarpaulins during handling, hoisting, and deployment.
