Suncall Translucent Corrugated Plastic Roofing

Suncall is a low cost translucent corrugated sheet, which is ideal for use around the home. Suncall corrugated sheets allow light to be gently and evenly diffused and reduce the glare from direct sunlight. They provide protection from the extremes of weather while making available ample natural light. When used around patios and pools they can serve as both privacy screen and windbreak but do not exclude the warmth of the sun. Suncall corrugated sheets are lightweight, flexible and easy to handle.

Suncall is inexpensive, so it is good value lightweight and easy to handle or store. Suncall has effective sheet coverage of 610mm.Before you order materials and commence building, please check the spanning table below will give you the maximum distance between battens and purlins.

Sheeting Information

Correct installation is important.

Suncall is fixed and flashed on similar principles as steel roofing. Start by fixing the first sheet at the end farthermost from the usual wind direction. If end laps are necessary, start at the bottom corner.

Allowance needs to be made when drilling screw holes so that the sheet can move freely as it expands and contracts. Screw holes must have a minimum diameter of 10mm. Avoid over tightening as this may cause the sheet to crack or split.

Before fixing sheets apply white paint along the battens or purlins to minimise heat build-up under the sheet. Heat build-up will cause damage to the sheet and cause it to discolour and deform.

The standard corrugated profile is side lapped by one corrugation, but depending on the degree of exposure and weatherproofing required, this can be increased to 2 ribs.

Handy tips:
You could try some practise holes using an off cut or part of a sheet which would be covered by ridging, flashings etc. You may find it easier to drill the hole for the screw first and then enlarge this to 10mm for the washer.

Important.
Do not store stacks of sheets in direct sunlight because sheets at top of the stack will act like a magnifying glass and could cause damage or distortion to the sheets at the bottom of the stack.

Like all plastic roofing products Suncall is subject to the effects of weathering and the very high levels of ultra violet light which are present in New Zealand. This means that over the years there will be some loss of light transmission and impact resistance. Please consult our Suncall brochure for the warranty.
