£50 Million Air Traffic Control Tower Gets Foamglas®
|
The new £4.2bn Terminal 5 at Londons Heathrow Airport is one of the biggest and most complex building projects in recent times in the UK. The 862 tonne control room and upper mast section for the new £50m steel air traffic control tower were fabricated off site and then lifted into their final position on top of a 4.8m diameter 65m high steel mast.
The uninsulated single-skin steel construction led to a risk of internal condensation in the plant rooms and lift shafts/stairways. FOAMGLAS® cellular glass insulation was chosed to be adhered to the inner faces of the upper mast section and underneath the floors. FOAMGLAS® was selected as the only insulation capable of giving decades of maintenance-free installed life without risk of internal condensation and offering complete non-combustibility.
The inherent strength and stability of FOAMGLAS® meant that it could be installed both locally and in Sheffield before the tower was moved to its final location.
Whilst the Heathrow control tower is an unusual application, FOAMGLAS® has been used successfully for many years on airport projects around the world.
The catastrophic fire at Dusseldorf airport in 1996 was caused by the use of plastic-foam insulation in ceiling voids. The fire and smoke led to 17 fatalities and an estimated £200m of damage. When Dusseldorf airport was rebuilt FOAMGLAS® cellular glass was specified for the roof, terraces, basements, ventilation and air conditioning ducts and chilled-water pipe insulation. Similarly 40km of chilled water lines up to 24 diameter were insulated with FOAMGLAS® for Frankfurts new Terminal 2 project. Reports on these projects are available on request.
FOAMGLAS® is the only truly 100% closed-cell, non-combustible (Euroclass A1) insulation material; its thermal conductivity is uniquely constant over time. These properties make it ideal for the demanding environmental and safety requirements of todays public buildings, particularly for air-conditioning and chilled water systems.
