Gel-Coated Natural Roof Lighting

Introduction

Topglass® GC is the flagship of the Topglass® natural lighting family of products, and uses an innovative manufacturing process developed by Alsynite NZ, whereby a 130 micron*.

EXO-SET 206 Premium Gelcoat 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 (see Topclad page 8).

Key Benefits

Manufactured from an acrylic modified polyester resin system and incorporating additional ultra violet stabilisers, Topglass® GC utilizes 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 Alsynites UV-stabilised 130 micron* EXO- SET 206 Gelcoat surface which is a reactive thermo-set to provide a high gloss surface.

Topglass® GC which is manufactured to meet the requirements of AS 4256:3.2006, is economical and provides flexibility whilst resistring UV degradation and yellowing much longer than is commonly experienced with general purpose grade translucent roofing products.

Harmful Ultra Violet Rays remain a major concern for today’s building designers. Topglass® GC can be supplied in a variety of pigments and can be supplied as Topglass® GC SPF. This innovative Gel-Coat additive provides excellent UVA and UVB block and offers exceptional heat and light data (refer page 7).
