Over many years a standard industrial grade, glass reinforced, polyester sheeting was the only type of grp roofing product available to the new zealand market. Although these types of translucent roofing products continue to perform adequately, the industry was seeking a superior product to resist new zealand`s harsh ultra violet climate. Utilising advances in fibreglass technology, alsynite nz ltd worked with the company`s raw material suppliers to develop a cost efficient product incorporating both uv-stabilised polyester weather surface technology and encompassing a purpose developed uv-stabilised core resin system. Key benefits
Topglass® is manufactured from an acrylic modified resin system, reinforced with high quality glass fibre rovings;
Technology developed in the united kingdom ensures only the highest quality uv-stabilised resins and weather surface protection coating is used in the manufacturing of the topglass® sheeting; topglass® encompasses in-built uv inhibitors which prevent early degradation, yellowing and embrittlement of the sheet; the product is oven cured and profiled to ensure maximum binding and strength; the non-porous weather surface prevents water absorption and osmosis; reduced fibre show in comparison to standard commercial grade translucent roofing products; the weather surface retains its smooth finish for a greater period of time providing self cleaning benefits; an extremely flexible product providing unique variation to meet design criteria;
Topglass® is an extremely cost effective uv resistant translucent roof sheeting. Harmful ultra violet rays remain a major concern for today’s building designers. Only topglass opaque uv smart pigment specifically developed by alsynite, provides 100% uvb block. This innovative pigment is also available included in topglass cool.
Applications
Commercial, industrial, institutional and other projects where long-term high quality lighting is required;
School/kindergarten and public outdoor areas requiring excellent uv protection.
Special applications
Topglass® can be supplied encompassing a purpose developed corrosive resistant resin for use in areas of extreme corrosion.
All topglass® products can be supplied in various twin skin systems providing excellent thermal benefits and energy savings.
Topglass® can be supplied tinted with variations to reduce light and heat transmission. This is recommended due to the long term clarity of the sheet; topglass® roofing profiles can be supplied in reduced width sheet if so required.
