Product Information

Full details

The PolyX Sheet End Closure 35mm is an essential finishing component for homeowners and contractors installing 35mm polycarbonate roofing systems. It provides a professional, clean edge to exposed sheet ends while actively directing rainwater into the gutter system to prevent structural damage. While it is highly effective for protection and aesthetics, it is strictly designed for 35mm sheets and requires the prior application of breather tape to maintain long-term weatherproofing.

Extended Product Information

FAQs

Does this closure seal the sheet against moisture?

No, this closure is a finishing profile. You must use anti-dust breather tape on the sheet edges to prevent moisture and dirt from entering the flutes.

Can I use this on 25mm sheets?

No, this product is precision-moulded specifically for 35mm polycarbonate sheets.

Do I need adhesive to install this?

Typically, the profile is designed to be a push-fit. Adhesive is generally not required unless the sheet end is damaged or uneven.

What is the purpose of the lip on the bottom?

The lip acts as a drip edge to divert rainwater away from the building structure and directly into the gutter system.

Is the material UV stable?

Yes, the PolyX range is designed for exterior use and can withstand typical environmental exposure.

Troubleshooting

Profile feels loose on the sheet

Check that the breather tape is applied evenly and is not too thick. Ensure no debris is trapped inside the channel of the closure.

Water is dripping behind the gutter

Ensure the closure is pushed fully onto the sheet so the drip lip extends past the edge of the polycarbonate.

Pros and Cons

Pros

  • Prevents water ingress behind gutters
  • Provides a clean finished appearance to roofing edges
  • Easy push-fit installation
  • Durable construction ensures long-term edge protection

Cons

  • Compatible only with 35mm polycarbonate sheets
  • Must be used in conjunction with breather tape
  • Not suitable for curved or non-standard sheet profiles

Setup, Compatibility & Care

  1. Preparation: Ensure the end of the 35mm polycarbonate sheet is cut square and clean.
  2. Tape Application: Apply anti-dust breather tape along the bottom edge of the sheet. This is a non-negotiable step to prevent condensation and debris buildup.
  3. Installation: Firmly press the PolyX closure onto the sheet end. Use light taps with a rubber mallet if the fit is particularly snug, ensuring the profile is fully seated.
  4. Compatibility: This profile is exclusively for 35mm thickness sheets. Do not attempt to force it onto thinner or thicker panels.
  5. Care: Clean the closure periodically with mild soapy water and a soft cloth during routine gutter maintenance to keep the drip lip free of debris.
