Griffiths Wood

External Wall Insulation

Scaling to new heights: the first-of-its-kind apartment block to tackle housing crisis.

Following Dublin City Council’s relaxation of height restrictions in 2018 to address the city’s housing crisis, developer Cairn Homes built Griffith Wood, a six-storey apartment block consisting of 380 energy-efficient homes.

Situated on a three-hectare site in the prime location of Dublin’s Griffith Avenue, the development is set in parkland with residential amenities and a crèche on its doorstep.

Cairn made its application to build Griffith Wood directly to An Bord Pleanála under the fast-track process for large housing developments. The independent body makes decisions on major infrastructure projects in the Republic of Ireland and, as the height cap was no longer in effect, permission to build was granted.

The apartment block was constructed using a steel frame system (SFS) with cement board in-fill panels. For the final finish, architects O’Mahony Pike wanted a brick façade on the front elevation and render on the remaining sides. They specified webertherm XM External Wall Insulation (EWI) system which they knew would allow this design flexibility while delivering improved thermal performance, having worked with Weber on similar buildings. The webertherm XM system can be used on high-rise buildings and has A2 fire classification, making it non-combustible.

The EWI system was built up by attaching 180mm thick webertherm MFD insulation to the cement board substrate, with a breather membrane applied to insulate the steel structural frame.

For buildings higher than two storeys, a wind load assessment needs to be calculated by a structural engineer and, together with pull-out tests conducted on site, a fixing analysis will need to be determined. This process was supported by the Weber specification team to ensure a safe, durable and long-lasting installation was made.

Initial work on the project started just after lockdown in April 2021 with all of the components stored at Weber’s Ballyclare plant in preparation. When construction was given the go-ahead they were able to hit the ground running, meaning that the project was completed on time, in early 2022
