Use self-tapping screws for timber purlins, and self-drilling screws for metal purlins.

Question 11

Why do polycarbonate roofing sheets require pre-drilling oversized holes?

Accepted Answer

Polycarbonate sheets are typically attached to support structures using screws or other fasteners. It is necessary to pre-drill oversized holes in the SUNTUF sheets to allow for expansion and contraction due to temperature changes. This is critical to ensuring the roof's quality and performance over time.

Question 12

How to accommodate SUNTUF polycarbonate roofing sheets' thermal expansion?

Accepted Answer

Polycarbonate roofing sheets can accommodate thermal movement by following these guidelines:

Keep a small gap where the SUNTUF sheets meet another object. Sheets expand most along their length, so pay attention to this direction.

Pre-drill oversize holes around the fixings. In this way, the screws won't stress the sheets.

Polycarbonate ridge caps, wall connectors, and flashings should also be predrilled with oversized holes.

Applying foam tape along structural elements that come in contact with sheets will reduce friction noise.

Leave a 5cm-10cm overhang over the lower purlin.

Question 13

Here are some tips for storing PVC sheets to ensure you get the most out of your investment.

Store your PVC sheets horizontally on a flat surface, such as a pallet or a shelf.

Ensure that no nails or bolts protrude from the platform. Even small rocks can leave permanent dents and scratches on the sheets.

Stack the largest sheets at the bottom, and the shorter, smaller panels on top.

Avoid stepping on PVC panels and placing heavy or sharp equipment on them.

Ensure that the PVC sheets are stored in a dry, ventilated, cool, shaded area away from direct sunlight.

Do not stack transparent or translucent sheets over opaque PVC sheets.

Avoid covering the sheets with dark films or other heat-absorbing materials.

Cover the panels with an opaque, bright, waterproof cover if you intend to leave them outdoors.

Keep your stack dry to prevent whitening and water spots.

Question 18

How many side overlaps does SUNTUF or PALRUF corrugates roofing require?

Accepted Answer

With a proper roof pitch, an overlap of one corrugation between sheets will keep the roof leak-safe, as long as the sheets are laid correctly.

Find the primary direction wind and rain are expected to come from and place the first sheet in the opposite direction. The next sheet will overlap the first, and so on. By doing so, you reduce the chance that water and dust will penetrate between the sheets.

Question 19

Question 21

Can SUNTUF corrugated polycarbonate or PALRUF PVC sheets be bent into arches?

Accepted Answer

Corrugated plastic sheets are tough and flexible. You can easily bend them to a curved roof without losing material integrity. There is only one rule: stay within the allowed arch radius.

In simple terms, an arc is a segment of a circle, and its radius is equal to its circle's radius.

Your sheet's minimum bending radius is determined by its profile (corrugation) and thickness.

Typical DIY polycarbonate corrugated sheets can bend to an arc radius of 4,000mm. Some of the more robust sheets require a minimum radius of 7,000mm. Check the specs of your sheeting to be sure.

Question 22

What is the right roof pitch for SUNTUF and PALRUF corrugated plastic sheeting?

Accepted Answer

A proper slope keeps water off the roof. It prevents leaks, keeps the roof clean, and ensures structural integrity.

Roof slope percentage indicates how much the roof falls over a given distance. For example, the roof slope would be 5% if it dropped 5 centimeters over one meter.

DIY corrugated plastic sheet typically requires a 10% slope. Some profiles call for a deeper slope. Check the specs of your sheeting to be sure.

Pay attention: If you expect leaves or snow to accumulate on your roof, consider a deeper slope.

Question 23

How to Install SUNTUF Corrugated Polycarbonate Roofing Sheets DIY?

Accepted Answer

Specifications vary between different products and sheet profiles. Read the installation instructions for the specific roofing sheet you have chosen and follow them carefully.

Here is a general outline of the steps involved in installing corrugated polycarbonate roofing panels:
