How to Store Polycarbonate Sheets?
+
Polycarbonate sheets are tough and durable and guaranteed to last for years.
Here are some tips for storing polycarbonate sheets to ensure you get the most out of your investment.
Polycarbonate should be stored 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 polycarbonate panels and placing heavy or sharp equipment on them.
Store the polycarbonate sheet in a dry, cool, ventilated, shaded area away from direct sunlight.
Keep your stack dry to prevent whitening and water spots.
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.

What Is the Right Saw for Cutting SUNTUF Corrugated Polycarbonate Sheets?
+
Safety First: Protect yourself by using professional equipment, keeping your surroundings neat and tidy, and using tools with caution and care.
 
Power tools
Circular table saws are the most efficient and accurate way to cut plastic sheets. This option, however, is rarely available on home improvement sites.
A portable fine-toothed circular saw is ideal for cutting on-site. High blade speed and moderate feeding rate will give you the best results.
A jigsaw also produces clean, accurate cuts, but requires better control. It is most suitable for cutting complex shapes and curved lines
 
Manual tools
Working with manual tools is time-consuming, but it reduces the possibility of sheet damage.
Manual handsaws with fine teeth provide accuracy and control.
Hand tools such as tin snips, scissors, or even a utility knife are useful when working with thin polycarbonate sheets or for making small notches.
 
Additional tools
You will need a flat, stable workbench to work on.
To set guidelines, you will need a tape measure, a ruler, and a marking pen.

How to Cut SUNTUF Corrugated Polycarbonate Roofing Sheets DIY
+
Corrugated polycarbonate sheets are common roofing materials for DIY garden shelters and outdoor canopies. On-site tailoring and trimming is simple. Follow these guidelines to ensure quality results.
Safety First: Protect yourself by using professional equipment, keeping your surroundings neat and tidy, and using tools with caution and care.
 
Place a layer of cardboard or plywood on the workbench before placing the sheets. This will protect the surface from scratches.
Place the polycarbonate panels on your workbench.
Clamp a few sheets together. This will reduce vibrations.
Polycarbonate sheets come with a removable protective film or marking strip. This film indicates which side of the panel is UV-protected. Do not remove it. You will need it later.
Use a measuring tape to measure the sheet, and make pen marks at each end. Join the marks with a ruler.
Do not rush measuring and marking. Once trimmed, you cannot patch the sheets together.
Secure the polycarbonate sheets to the workbench surface to prevent movement and vibrations.
Support the sheets near the cutting line. You can do this by placing a timber plank on top of the sheets, parallel to the markings.
Cut along the marked pen line. The preferred method is to use a fine-tooth saw that rotates at high speed. 
Advance the saw slowly and steadily and do not stop once you have begun. It will ensure a clean, consistent edge.
Remove leftover cuts and scraps from the cutting table.

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

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

What is the recommended purlin spacing for SUNTUF corrugated polycarbonate roofs?
+
The required purlin spacing for corrugated polycarbonate roofing depends on a number of factors, including the size and type of corrugated sheets. In addition, the type of support structure, and local building codes.
Follow Palram’s technical guidelines for the specific SUNTUF product you have chosen. This will ensure that the roofing is properly supported and able to withstand the loads and stresses it will be subjected to.

Which side of the SUNTUF roofing sheet should face up?
+
Look for a removable strip that indicates which side of the sheet is UV-protected.
It is critical to install the sheets with the UV-protected side facing up. 
Remove the marking strip after installation.

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

How to accommodate SUNTUF polycarbonate roofing sheets’ thermal expansion?
+
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.

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

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.

Which screws to use for fixing corrugated SUNTUF and PALRUF roofing sheets?
+
Use corrosion-resistant screws for optimal long-term service
Use screws with an outside thread diameter of ¼”
Screw shaft length varies with corrugation profile and fixing location (crest or valley).
Use self-tapping screws for timber purlins, and self-drilling screws for metal purlins.

What kind of gasket is suitable for corrugated SUNTUF and PALRUF sheets?
+
Flexible EPDM gaskets with metal washers.
Flexible EPDM gaskets allow just enough free movement for the sheets as they contract and expand. This ensures an effective seal against leaks and reduces stress and micro cracks. The metal washers will distribute the fastener load and will support the gasket.
Gaskets should conceal holes properly.
Use a 25mm gasket for a 10mm drill. A 19mm gasket is the alternative when the corrugation profile does not allow a wider gasket (if the valley or crest is too narrow).

Can polycarbonate light transmittance be degraded over time?
+

SUNTUF roofing sheets are made with a UV protection layer. This layer protects the sheets from UV radiation harm and maintains light transmittance and quality for many years.
