Topglass® GC is the flagship of the Topglass® natural lighting family of products, and uses an innovative manufacturing process developed by Alsynite NZ whereby Silmar® SIL12BE-1659 100-micron gel-coat is applied to the weather surface of the sheeting.
Offering exceptional resistance against corrosive atmospheres and providing protection against solar deterioration, Topglass® GC brings additional benefits to building designers and owners. Topglass® GC can also be supplied in solid colours, providing an excellent alternative to metal roofing and cladding systems in corrosive environments.
Features and Benefits
- Manufactured from an acrylic modified polyester resin system and incorporating additional ultra violet stabilisers, Topglass® GC utilises antistatic high quality glass fibre rovings to give maximum strength during the curing and bonding process.
- The ultimate benefit of the Topglass® GC product over general purpose grades of GRP natural roof lighting products is the addition of a UV stabilised 100-micron Silmar® SIL12BE-1659 gel-coated surface which is reactive thermo-set to provide a high gloss surface.
- Topglass® GC, which is manufactured to meet the requirements of AS 4256:3, is economical and provides flexibility whilst resisting UV degradation and yellowing much longer than is commonly experienced with general purpose-grade translucent roofing products.
- Harmful ultraviolet rays remain a major concern for today’s building designers. Topglass® GC can be supplied in a variety of pigments, and can also be supplied as Topglass® GC SPF.This innovative gel-coat additive provides excellent UVA and UVB protection and offers exceptional heat and light data.
Applications
- Roof and wall lighting to all commercial, industrial, institutional and other buildings requiring long term natural lighting without early surface degradation.
- Schools and childcare centres
- Public outdoor areas requiring good UV protection
