GloWorks – Welsh Larch – Revisited

Project: GloWorks, Porth Teigr, Cardiff

Timber Species:  FSC Welsh Larch

Timber Treatment: “MicroPro” Treated

Main Contractor: Vinci, Cardiff

Project Start date: 2013, (completed May 2014)  See original case study/ photos here.

A prestigious project designed to meet BREEAM Excellent, in an area that is becoming a hub for Wales’ dynamic creative sector. A 50 x 150 specially sawn and selected FSC Welsh Larch was used.

NORclad “MicroPro” treatment was used and the product was selected based sustainability, a 30 year Koppers treatment warranty against rot and fungal (out of ground contact) with little or no maintenance required, and other important considerations such as cost and ease of installation. This treatment allows the timber to still naturally weather to a silver/ grey which was desired by the Architects.

Revisited: May 2016

The project has started to weather now, the natural variation is starting to show across the boards. Certain boards are not weathering as quickly, typically through elevation or the shade that may have been created. Overall the project looks great, and will be a nice project to monitor over the next 12 months to see further change.
