Grid Bar Overcladding System

Grid Bar System
We offer a grid bar support system that can be used to overclad a leaking roof that cannot be removed.

This system can also be used to create a insulation gap over an existing single skin roof.

The grid bars must be installed over the existing purlins and is not advisable to use this system on a fragile roof.
Please contact us with your roof plan and purlin details for a quote or if you wish to discuss this system in more detail.


Gris system support bars are manufactured from 1.25mm thick galvanised steel and are supplied in either 1m 2m or 3m lengths to suit your purlin run. Grid bars incorporate a spigot end for easy on-site connection.


The brackets are manufactured from 1.6mm thick galvanised steel supplied with a 3mm thick EPDM base thermal pad. Brackets are installed using a twist and lock system.

Bracket sizes are as follows:

60mm, 80mm, 85mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, 210mm, 220mm, 230mm, 240mm, 250mm, 260mm, 270mm & 280mm
