Product Information

Full details

The Ogee Fascia Internal Corner is designed for professional roofline installers and DIY enthusiasts looking to achieve a seamless finish on their roofline projects. It serves as the critical solution for concealing the mandatory 10mm expansion gap between PVC fascia boards at internal corner points, such as the foot of a valley. While it provides an essential aesthetic and functional bridge, users must be careful to follow specific bonding techniques to allow for thermal expansion, or the installation may suffer from bowing or joint failure.

FAQs

Can I use this on non-Ogee fascia?

No, this corner is specifically profiled to match the Ogee aesthetic and will not provide a flush fit on square or bullnose fascia boards.

What tools do I need for installation?

You only need a standard fine-toothed saw or hacksaw for cutting, a tape measure, and a silicone applicator gun.

Do I need to glue both sides?

No. Only glue one side. The other side must be sealed with low-modulus silicone to allow the material to move during temperature changes.

Is the 10mm gap mandatory?

Yes, PVC expands and contracts significantly with temperature changes; failing to leave a gap can result in structural failure of the fascia joints.

Can I paint these to match a custom color?

Generally, PVC roofline products are designed to be maintenance-free and are not intended to be painted. Painting may void warranties or cause the PVC to absorb more heat, leading to distortion.

Troubleshooting

Joint is buckling or bowing

This indicates the fascia boards were installed without the required 10mm expansion gap. You may need to trim the fascia back to allow for movement.

Silicone is pulling away from the joint

Ensure the surface was cleaned with a solvent wipe before applying the silicone. Use only low-modulus silicone to ensure enough flexibility for thermal movement.

Pros and Cons

Pros

  • Seamless aesthetic integration with Ogee fascia profiles
  • Essential for preventing water ingress at valley foot corners
  • Simple to cut and customize with basic workshop tools
  • Provides necessary clearance for material thermal expansion

Cons

  • Requires specific adhesive and silicone application to function correctly
  • Improper installation can restrict expansion and cause board warping
  • Limited to use with Ogee-style fascia boards only

Setup, Compatibility & Care

To install, ensure your fascia boards are cut with a consistent 10mm gap at the corner junction. Use a fine-toothed saw or a standard hacksaw to trim the internal corner component to the required height of your fascia.

Installation Steps:

  1. Measure the required length and cut the trim accordingly.
  2. Clean the surface of the fascia boards to remove dust or grease.
  3. Apply PVC adhesive to one side of the trim and press firmly onto the first board.
  4. Apply a bead of low-modulus silicone to the interior of the opposite side of the trim before slotting it over the second board.
  5. Wipe away any excess silicone immediately to prevent staining.

For care, simply wipe down with a damp cloth and mild soapy water during your routine gutter cleaning schedule. Avoid abrasive sponges or harsh solvent-based cleaners that may damage the PVC finish.
