Fitting Ultralite 500 Roof-in-a-Box

The Ultralite 500 is designed as a complete roof system and is manufactured to offer a product that can be fitted quickly and easily.

To help with this, each Roof-in-a-Box is supplied with a comprehensive Installation Guide, which steps through the process from preparation right through to completion.

Get the Right Size Roof-in-a-Box

Whenever possible, the structure should be designed to use panels in full widths and standard lengths, as this can leads to cost and labour savings.

The following tables show standard pack lengths and widths and the external frames sizes that they are built for.

Design to Modular Sizes

To reduce labour time and minimse cost, make the most of the modular sizes by designing new-build projects to the external frame sizes shown here.

Fitting to Non-Modular Sizes

Panel length and width can be cut to fit to an existing, non-modular frame size. If necessary, the length should be cut at the opposite end to the Pre-Cut Drip.
