How To Assemble A Multiwall Polycarbonate Roof - Tuflite Polymers

Choosing a multiwall polycarbonate sheet to build your roof is a great choice, but you also need to know how you can assemble the sheet to build the roof for your structure. So, here’s the perfect guide.

Cutting the polycarbonate

Before building a roof, you need to know the right dimensions you require for the roof. Only with the right dimensions can you cut the sheet to the required size. So, take up the dimensions, and mark the same on the sheet. After marking the sheet with a pen or marker, you can easily cut the sheet with the help of sharp-toothed scissors or a circular saw. It is very easy to cut the sheet on your own, which does not produce any harmful or toxic shards.

Taping it up

Once cut, you can then apply solid tape to the top of the sheet, which is nearest to the wall. You must also apply a vented tape to the other end, which runs near the gutter. Such taping can help protect the sheet from any water ingress. To protect the same from the gutter, you can have a U-profile clipped over the vented tape. Also, once the sheet is in position, you can apply a capping bar.

Rafting the sheet

You can then have a rafter gasket, which will be sitting down on a jointing rafter, where you will have 2 sheets coming side by side. You must allow for an expansion on the sheet, so that when the sheet heats up during the day, and cools down at night, the sheet will expand and contract due to the co-efficient of linear expansion. You must thus leave a 10-12 mm gap between the 2 sheets. Taking care of all of this, you must then insert screws to tighten the sheets in place. But remember not to over-tighten the screws, as you need to leave some space for expansion and contraction. Lastly, you must install an aluminum F-profile on the gable end of the sheet, for a last finish and fix.

Water-tight sealing

Once all of it is done, you can then achieve a water-tight seal between the house wall and the multiwall polycarbonate sheet. This can be achieved by using a butyl-backed lead flashing, which can be easily adhered to the sheet and the wall. Moreover, the butyl backing makes it a very easy process, as compared to using standard lead. 

You can see how it is so easy to assemble a multiwall polycarbonate roof. You may thus call on a professional to build your roof, or build it up on your own as it is such an easy procedure.
