AshGrid™ was the first spacer system for built-up metal roofing and cladding developed for the building envelope market. AshGrid™ has maintained its market leading position since its launch through a continued programme of research and innovative development.

As part of this programme, a new ABV Bracket has been introduced, incorporating four points of contact with the bar and requires no sway brackets. The ABV Bracket is available in a range of depths from 180mm-400mm to comply with any building regulations.

The installation is a simple three step method which saves time and costs for onsite construction. A new SafeLoc bar and bracket has also been introduced, tight fitting and reliable bar connections are essential to ensure the stability of all spacer systems during constructions.

Unlike some systems that rely on fixings to prevent the bars separating the enhanced AshGrid™ AG40 spigot design with its new SafeLoc security feature provides enhanced structural performance and reduces risks on site at the click of a tab.

Manufactured to the highest standards including BS EN ISO 9001:2008, all AshGrid™ components are produced to Ash & Lacy design and performance specifications following stringent quality control procedures. Offering a wide range of bracket height and an assessed firewall solution, AshGrid™ is available nationwide from strategically positioned manufacturing locations.
