Special Purpose - Webglas GC

Webglas GC by Ampelite is proving its worth in buildings where steel and other roofing or wall cladding materials deteriorate or corrode at an unacceptable rate. The sheet weight is 3660 grams per square metre, 2mm thick and is reinforced with a heavy gauge woven glass mat which provides continuous strength and protection in every direction. The overall strength is such that wire safety mesh is not required. This is of particularly importance in chemically aggressive and corrosive environments where safety mesh can eroded and traditional steel cladding can quickly deteriorate.

Where corrosion resistance is vital, complete buildings can be clad and roofed with "Webglas GC" which can be either 100% opaque, or translucent to transmit natural light. For extreme environments, where high levels of acids or alkalinise may occur, "Webglas GC+" which incorporates vinyl ester resins, will provide additional protection. What really sets Webglas GC apart is its combination of strength, high resistance to a wide range of chemicals and very low surface erosion. The warranty covers surface erosion for 20 years.

The special resin technology used in the highly UV resistant surface coating and sheet is the same as that used for Ampelite's premium grade "Wonderglas GC", now very widely used in major projects around Australia. "Webglas GC" therefore provides a maintenance free roofing and cladding guaranteed for a specific lifetime.

The physical properties highlight the benefits of "Webglas GC"

• The additional reinforcing provided by the heavy woven mat construction eliminates the need to install wire mesh below the sheeting. This makes "Webglas GC" particularly suitable for use in public buildings and schools, or wherever there may be access to the roof.
• Strong looking. Weave pattern has good visual appeal.
• The standard thickness of 2.2mm has greater spanning capacity due to being heavy gauge combined with the additional strength of the woven mat.
• The top (weatherside) is gel coated with a specially formulated highly UV resistant resin. This part of the process is identical with Ampelite "webglas GC" premium grade sheeting and provides virtually undiminished performance for 20 years.
• Loss of light transmission after 10 years is just 10% compared to a loss of 30% for standard fibreglass. Very high resistance to yellowing and discolouration. Over 10 years change is negligible and covered by Warranty, only minor changes occur in later years. In addition, inbuilt UV protection eliminates 99% of harmful rays.
• Surface erosion is eliminated and covered by Warranty for 20 years. Low surface erosion also improves weathering properties. The gel coated surface provides an almost impenetrable barrier and is warranted against water penetration for 20 years.
• Better resistance to a range of commonly used chemicals than standard fibreglass (which is good), details can be provided.
