Knauf Insulation’s Earthwool Building Slab was chosen for The Queen’s Terminal at Heathrow.
The task was to develop a roofing structure that would be vital to the overall appearance of the building and one that would fulfil the stringent acoustic criteria – whilst working to tight deadlines.
Knauf Insulation’s Earthwool Building Slab RS45m product in 50mm and 75mm were specified within the 40,000m2 Kalzip System in the AluPlusPatina finish.
Heathrow’s Terminal 2, also known as The Queen’s Terminal, boasts exceptional architectural design and is 40% more carbon efficient than the previous building. Kalzip’s large waveform roof bestows one of the iconic features of the terminal.
A multi-layer approach was taken when it came to installing Earthwool Building Slab RS45. By layering the insulation products in different densities across the Kalzip standing seam roof, rigorous sound absorption and sound transmission measures were met, whilst retaining the form and functionality required by the designers.
As a robust, resilient and dense rock mineral wool insulation slab, Earthwool Building Slab RS45 has excellent acoustic properties that help to reduce the impact of airborne and rain impact noise. It also has an excellent thermal conductivity of 0.035W/mK, helping to provide passengers with a comfortable environment.
