Riverbank and Newbank Towers in Salford, are two high-rise residential tower blocks owned and maintained by award-winning housing provider Salix Homes. Built in the 1960s, both 16-storey tower blocks are identical in their face brick construction.
As part of the ongoing upgrade of its high-rise properties, Salix Homes embarked on a £6.6m improvement programme of both blocks, bringing them up to the Government’s Decent Homes standard.
3000m2 of Alumasc’s industry-proven Swisslab EWI was installed by BLD Construction (Facades) Ltd using 60mm Phenolic Insulation and finished with a combination of traditional clay brick slips to the lower floors – chosen for their high levels of impact resistance – with the remaining floors completed using silicone render, specified for its lightweight properties which minimise the structural impact of the system.
Alumasc’s technical team worked closely with the Rainscreen Manufacturer and the Project Architect to accommodate the inclusion of rainscreen cladding between the windows.
To ensure the interfacing detail between the EWI and the rainscreen panels was not susceptible to water ingress, the EWI was continued behind the rainscreen system with Alumasc’s hydrophobic scrim adhesive used to provide a waterproof seal around the brackets of the rainscreen system. This detail provides continuity to the thermal performance and eliminates cold bridging.
Commenting on the project, BLD Director, Bruce Day, said: “We have a successful track record of using Alumasc products on many high rise projects.
Alumasc EWI systems deliver really impressive results when it comes to improving energy efficiency. Swisslab was specified for this refurbishment due to its requirement of only 60mm phenolic insulation to achieve the required U target.”
Residents of Riverbank and Newbank Towers now enjoy warmer homes and lower energy bills with an achieved U value reduction from 1.47W/m2k to 0.26W/m2k.
