In April 2002 council tenants in Glasgow made the historic decision to vote in favour of transferring their homes to private ownership. The verdict ensured that the city’s 80,559 council homes would soon be operated by a privately-run housing association. The change would free up more than £1 billion of private money to replace where necessary and refurbish “crumbling damp houses into attractive modern homes”. A project planned over an 11 year programme.

The GHA is a registered charity and operates as a not-for-profit housing association. It has the distinction of being the largest social landlord in Britain.

In March 2004 Glasgow Housing Association launched a massive procurement process by placing notices inviting contractors to bid for work totalling over £750 million over five years. It included building new homes, providing new kitchens and bathrooms, insulatedovercladding, central heating and rewiring and demolition plus refurbishment of tower blocks. The project is set to deliver 4,511 new over-claddings to single and multi story blocks.

As may be expected from building work of such stature, there are a variety of substrates to be considered where rendered external wall insulation is to be installed. In addition to brick, concrete and concrete panel includes a high percentage of the more difficult no-fines.

Andy Wallace, Sales and Marketing manager for Dryvit UK said;
“EJOT has a wide range of quality fixings and anchors in addition to a reliable service offer which ticked all the boxes when we were selecting a key supplier of ancillary components to complement our range of insulated render systems. The Glasgow Housing Association projects presented a number of challenges, not least the number of different substrate types ranging form exposed pre-cast concrete panels to Wimpey no-fines. EJOT were able to carry pullout testing on each building type using various anchors within their portfolio to determine the most suitable anchor for use with the Dryvit Roxsulation system in terms of both performanceand cost. The results from the testing were then used by our engineer to establish number of anchors and layout per meter squared to satisfy wind loading and ultimately Building Control requirements”.
