ROCKWOOL insulation has been installed on the external envelope of a new housing development in Dublin to provide low-energy housing for its residents.
Durkan Residential’s Silken Park features a combination of two, three and four bedroom housing, designed to offer sustainable living environments that are both healthy and comfortable to live in.
Main contractor Ecofix Ltd adopted a ‘fabric-first’ approach to the project to build well-insulated and airtight properties through the use of an external wall insulation system that completely wraps the houses and therefore minimises thermal bridging.
The external wall insulation incorporated ROCKWOOL External Wall DD Slab, ROCKWOOL’s BrickShield and ROCKWOOL REDArt Silicone render systems.
BrickShield was installed to provide a real brick finish on external wall insulation. ROCKWOOL insulation boards were fixed around the perimeter of each piece of insulation and mechanically fixed with thermally-broken insulating wall anchors.
Renowned for its thermal performance, fire protection and aesthetics, the ROCKWOOL REDArt Silicone EWI System was installed to minimise the resident’s heating requirements and provide a high standard of thermal comfort at Silken Park.
Jay Stuart, technical director at Ecofix UK and Ireland, explained how ROCKWOOL’s dual density system was ideal for the project at hand:
“[Dual density] means it is impact resistant on the outside, and slightly softer on the inside where it is fitted against the masonry wall. This means that the slab compresses and fills all the unevenness on the masonry wall achieving a perfect fit of insulation. In addition, the technical support ROCKWOOL provided was second to none which helped in the delivery of the project on time.”
ROCKWOOL’s thermally engineered and environmentally-friendly solution has helped to provide energy efficiency and reduced heating consumption. Durkan Residential’s commercial director Andrew Kinnear commented that the development is seeing savings of approximately 10 percent in the external walls.
