TECHNICAL GUIDE

Step-by-Step Installation

Ensure your project meets British Building Regulations with our verified fitting process[cite: 1, 4].

01

Structural Prep

The upstand opening must allow for a 5mm tolerance on each side. The internal distance must be 10mm larger than the quoted size[cite: 40].

02

Support Timber

Install 25x50mm timber support[cite: 49]. Ensure the top of the support for triple glazed units is exactly 42mm below the upstand top.

03

Seal & Level

Apply foam rope on the timber support to level discrepancies and prevent glass cracking[cite: 69]. Failure to use foam rope voids your warranty[cite: 70, 83].

Pro Tip: Use DOWSIL 791 Weatherproofing Sealant[cite: 103]. DO NOT use acrylic sealants as they cause loss of adhesion and leaks[cite: 104, 82].
