Sunglaze Gasket Roll (10m or 25m)
The Sunglaze Gasket Roll is an EPDM rubber gasket used with the Sunglaze side joiner, and it is the part you reach for when a sheet has been cut down in width. Polycarbonate sheets are made to a set width, but roof designs rarely work to the sheet width exactly. When you trim a sheet, you expose a raw cut edge, and that edge needs a gasket to seal the joint properly.
The gasket sits inside the side joiner assembly and beds against the cut edge of the sheet. Because it is EPDM, it stays flexible across temperature changes, which matters because a solid polycarbonate panel moves noticeably between a cold winter morning and a hot summer afternoon. The gasket keeps that joint sealed without cracking or going hard.
The roll is supplied in 10m or 25m lengths and is trimmed to fit on site. Order the longer roll if you are covering a large roof area or a run of several cut sheets, and keep a roll spare for future maintenance.

What You Need To Complete The Job
The gasket is used with the Sunglaze Side Base and Sunglaze Side Cap joiner profiles that finish a trimmed sheet edge. If you are trimming sheets to width for the first time, the whole side joiner set belongs in the same order. The full range is in the Sunglaze category, and the sheets themselves sit under Polycarbonate Roofing.
Frequently Asked Questions
When do I need the gasket roll?
You need it whenever a Sunglaze sheet is cut down in width. A trimmed sheet leaves a raw cut edge, and the gasket seals that edge inside the side joiner so the joint stays watertight. Sheets used at their full manufactured width do not need it.
How much gasket do I need?
Measure the total length of cut sheet edges you need to seal and add a little for waste and joins. A 10m roll covers a typical small pergola; a 25m roll suits a larger veranda or a run of several cut panels.
Is the gasket easy to fit?
Yes. It is fitted into the side joiner assembly and trimmed to length with a knife or scissors on site. Because it is EPDM it is flexible and easy to work with, even in cooler weather.
Why EPDM rather than a cheaper rubber?
EPDM stays flexible across a wide temperature range and resists UV and ozone, so it does not crack or go hard the way cheaper rubber can. On a roof that moves with temperature, that flexibility is what keeps the joint sealed for years.
Does the gasket suit both 10m and 25m rolls the same way?
Yes, the material is identical; only the roll length changes. Choose the roll that best fits your project size so you are not left short or paying for a long roll you do not use.
