Neat finishing of the rooflight with the Kerb Top Trim finishing profile

Back to all blogs | Glazing Vision Europe | Tutorials

When placing a rooflight or roof access hatch, of course you want the finishing to be proper on all fronts. One of the options when ordering a rooflight or roof access hatch, is the so-called ‘Kerb Top Trim’. Our customer often ask us what this is exactly and what the advantage is. In this article we explain what a Kerb Top Trim is and how it works.

What is a Kerb Top Trim?

A Kerb Top Trim is a finishing profile. It has two purposes. Firstly, it neatly covers the top side of the raised edge. Secondly, it is used on the inside to neatly finish the recess.
The finishing profile is a coated aluminium profile and is delivered in off-white (RAL 9010) as standard. It is however available in any desired RAL-colour.

How does it work?

You place Kerb Top Trim before the rooflight or roof access hatch is placed. It falls across the raised edge and over the end of the plasterboard. There are grooves to cut the finishing profile to size, to prevent a thermal bridge. There is also a groove in which the screws can be placed to fasten the finishing profile.
Detailed sketch below indicates how the profile falls across the plasterboard, how it should be fastened with the screws and how the slope can be adjusted to an angle of 5 degrees.

How much do I need?

Trim is supplied in two metre lengths so please order the appropriate amount for your rooflight, for example:

  • A 2m x 1m rooflight will require 3 x 2m lengths
  • A 3m x 1m rooflight will require 4 x 2m lengths

What is the standard colour?

The Kerb Top Trim is standard RAL9010 Pure White
