Description
End Closures for Polycarbonate Sheets and Glass Units
Protects your polycarbonate or glass roof sheets!
Also known as "U" Drips or "U" profile, these End Closures are designed to protect both polycarbonate and glass roofing material.
Fitted to the gutter end of a pitched roof, such as a conservatory, or to both ends of a free-standing roof. End Closures act as a protective and decorative finish while providing a flexible barrier against water ingress. Drainage holes on the underside of the end closure help to reduce moisture and prevent the forming of condensation.
Features & Benefits
- Seals open end of sheets and glass units
- Prevent dust and insects entering sheets
- Protects vented anti-dust breather tape
- Prevents UV light breaking down glass unit seals
- Low-profile top stops water settling on closure
- Drip face prevents water running towards roof
- Drainage holes prevent moisture build-up
With three sides protected by glazing bar and ridge cappings, the gutter end is often the only edge exposed. When left exposed, the sun's UV can affect the seals around the glass unit, which could lead to units failing within just 12 months. End Closures helps stop this from happening and the 'drip' face to the front stops water running back up under the roofing material.

Fitting and Usage
Prepare Roof Material
Whether fitting to glass or polycarbonate, it's important that the material is cleaned and dried thoroughly to ensure that the End Closure works effectively. This is particularly significant on the top face, which will be sealed with silicone.
Anti-Dust Breather tape seal
If fitting to a polycarbonate sheet, ensure that Anti-Dust Breather tape is used to seal where the End Closure is being applied to. If breather tape is missing, or in a poor state, then the end of the sheet should be re-sealed.
Anti-Dust Breather tape allows the movement of air inside the panel and the draining of any condensation, while preventing insects and dust from getting inside. The maximum breathability offered aids the dispersal of moisture that could otherwise lead to unsightly algae and mould. Anti-Dust Breather tape is not weatherproof and should therefore be protected by an End Closure.
Fitting the End Closure
Cut the End Closure to the desired length, ideally the same width as the existing roofing material. Remove any swarf created when cutting the End Closure.
We recommend that a small bead of silicone is applied to the top edge along the entire length of the End Closure. This will seal the top face of the sheet and prevent water from entering the End Closure and making contact with the breather tape. It is important that polycarbonate compatible silicone is used as standard silicone may release an acid which can cloud the polycarbonate.
Further Advice
To helps the polycarbonate or glass sit flush on the glazing bar gasket, we recommend that a section of drip is removed from the ends where the End Closure rests on the glazing bars.
