FAQs

Yes, this has the same characteristics: virgin polycarbonate material, 0.8mm thickness and UV protection. It is also the same profile and runs into coloursteel easily.

SUNCOVER sheets come with a 10 year warranty and STARCOVER with a 15 year warranty.

They don’t look too different. However, the Suncover has a 0.04mm UV protective coating and the Starcover has a 0.06mm coating.

This is why Starcover has a 15 year warranty and Suncover has 10. Starcover is also processed slightly differently making it optically clearer.

Polycarbonate is a thermoplastic polymer. It is very strong, flexible and does not shatter. It also has a UV protective coating applied to it giving protection from the sun.

PVC is very cheap to produce however it goes brittle quickly and will generally only last a couple of years. This is because it’s usually only UV stabilised, not UV protected.

You’ll probably need fasteners which are specifically for polycarbonate roofing.

We also stock accessories: noise stop tape to stop creaking due to temperature change, foam infill to stop wind or debris going in-between the sheets and the purlins and we stock flashings.

If you don’t know what accessories you need, feel free to contact us, we’re happy to help.

Yes, the corrugated profile has the same wave length and pitch, and runs easily into coloursteel.

We also have Greca and 5-Rib profiles. The 5-Rib matches Styleline, T-Rib, or Trimdek.

All colours block out 99.5% of harmful UV rays for SUNCOVER and 99.9% for STARCOVER. This is because the UV protection is applied to the top side of the sheet, and has nothing to do with the colouring in the sheet.

It’s important to ensure the sheet is installed with the UV coating facing upwards towards the sun.

The Twinwall has UV protection both sides, so either side can go towards the sun.

The profiled polycarbonate has UV protection on one side only. This will be clearly marked with a sticker and writing on the sheet.

Custom Glaze can only be installed one way, with the interlocking ridges facing up.

Yes. Clearlite roofing generally refers to any type of clear plastic roofing.

There are three main types – polycarbonate roofing, fibre reinforced plastic (FRP) and PVC.

Polycarbonate roofing is the clearest and strongest.

Condensation is caused when warm air collides with cold surfaces. So if the sheets are cold and the air inside is warm (i.e. you have it installed in a sun-room or similar) you will get condensation on the inside.

The only way to stop this is to ensure that the temperature under the sheets is the same as the temperature outside, by using adequate ventilation.

Because Twinwall is insulated (like double glazing), it reduces the chances of getting condensation. So it’s more suitable for enclosed areas.

You should try to build your structure in such a way so you don’t have to use any sealants.

If you do need to, there are only a few that are suitable (most will adversely affect the polycarbonate). Ensure it says that it’s suitable for polycarbonate on the back.

The following are suitable:
HOLDFAST FixAll 220 MS
HOLDFAST FixAll MS Crystal

Yes! We have a whole section with technical data sheets and further information.

You can use a sponge or very soft brush with soapy water or detergent. It is very easy to scratch so don’t use any hard bristles or brooms.

It’s also not recommended to waterblast it.

Some household cleaners will adversely affect the polycarbonate. The following are suitable though:

• 30 Seconds Roof Treatment
• Wet & Forget Moss, Mould, Lichen & Algae Remover

Yes! We’ve had lots of customers using it for a greenhouse.

Whilst it blocks UV within a certain wavelength, it still allows the necessary light and heat through for plants to grow.

No. It’s nice to have them installed at 600mm to hide the joins, but they don’t have to be at that distance.

The purlins (going cross ways) are the ones actually supporting the sheets, and they need to be at 1500mm apart.

No. Plenty of customers have used different joining systems, such as aluminium, or existing systems they’re just replacing the sheets on.

The sheets need to be supported every 600mm for 6mm and 800mm for 8mm.

The 5-Rib or Custom Glaze is better for low pitched roofs.

This is because they have a higher ridge on the joins, so less chance of water coming up and in-between the joins or fasteners.

Yes, if you’re picking up we can help you roll it into a tube. I.e. 2.4m sheets will roll into a tube about 200mm wide and 2.4m long.

It’s then quite easy to tie onto roof racks or a trailer, the shorter sheets will even fit in a van or station wagon.
