ENERGY REFURBISHMENT OF 854 APARTMENTS USING ROCKWOOL REDAIR FLEX SYSTEM

ROCKWOOL REDAir FLEX was used to externally re-insulate and renovate 854 apartments from 1968

ROCKWOOL REDAir FLEX ventilated façade system was used to externally re-insulate and renovate 854 apartments from 1968. The system is mounted to the existing concrete façade elements.

Windows mounted with less risk of thermal bridges
The project has also used another ROCKWOOL system as an installation base for the windows named REDAir LINK system. Client adviser Niels Ole Overgaard says:
“The windows are positioned well out in the insulation, so here we should have a robust and thermal bridge free solution. REDAir Link system uses hard-pressed insulation as an in-organic support frame for the windows. It has made it simple to install and close around the windows in this highly insulated facade.

Easy and simple to work with
The contractor responsible for the installation was positive. Brian Hasfeldt, Project Director of NCC, said:
“We’ve experienced that the system is simple and easy to work with, so installation goes fast. The materials have proven fire safety, which means that we can meet the fire safety requirements for buildings over five stories.”

Better energy solution and better total economy
Niels Ole Overgaard from architect firm Paludan & Ramsager was also positive and says:
“At first we had planned with a traditional façade solution but decided to change when we became aware of REDAir FLEX system. We found that the system guarantees a facade nearly free of thermal bridges. It is also easy to mount, with few building processes. The result is that we both have a better insulation solution and an improved overall economy.”

The weather forecast doesn’t delay progress
Usually, Danish weather is a challenge for contractors, but here the system also has an advantage:
“REDAir system can be exposed to weather, so we can work in all conditions. It also means that we don’t need to cover the scaffolds. This makes it less dark in the apartment during the renovation for the benefit of the residents,”says Brian Hasfeldt.
