High-pressure laminate
Alloc Commercial says its flooring now has a thicker and stronger high pressure laminate surface and an integral Silent System sound absorbent underlay. Alloc says the surface resists damp, diluted chemicals and cigarette burns and has been designed to endure heavier impacts. Alloc has also launched the new StoneStructure decor, which is designed to look like stone and comes in travertine, granite and slate versions.

Eco-friendly floor hits the high street
Clothing retailer H&M has specified Amtico's Stratica eco-polymeric flooring as part of its commitment to eliminate PVC from its stores. Amtico says that Stratica contains no plasticisers and so emits a very low level of volatile organic compounds (VOCs). It also requires no dressing or cleaning with caustic chemicals, thus minimising lifetime cost and environmental impact. H&M has chosen Stratica Oak and Stratica Limestone flooring for its 43 UK stores. Stratica flooring has a 10-year guarantee on its wear layer.

Treat concrete floors in one
Laybond has introduced ScreedMaster One Coat Membrane for power-floated concrete floors. The One Coat Membrane is applied by trowel or roller and is ready for overcoating after approximately eight hours at 200C. This enables the early laying of moisture sensitive floor coverings according to Laybond. One Coat Membrane is black, which Laybond says makes it easier to identify treated areas.

Quick-drying floor screed
CG Flooring Systems has launched a cementitious floor screed that can be laid at a rate of 1000 m2 a day and will take wheeled traffic within 24 hours of being laid. Fastfloor-IT is a water-based pump-applied material that CG says allows a large quantity to be laid in a short time. The fast curing time is a combination of special cements and acrylics. The company says the material contains no solvents and is odourless. The screed can be between 5 mm and 25 mm thick, and has self-smoothing properties. Before laying the screed, CG carries out the preparation work to BS8204 Part 3.

Recycled carpet backing

Tandus has introduced a carpet recycling system to the UK. Tandus says it will collect any used vinyl-backed carpet and take it to its facility in Blaina, Wales, where it will be baled and shipped to the firm鈥檚 recycling factory in the US. It claims that 100% of the returned carpet is processed into vinyl backing. The carpet fibres become an integral part of the backing, adding structural strength, which Tandus calls upcycling. The company will accept its competitors鈥� carpets and says that the vinyl backing can be recycled indefinitely.

Air apparent: The next generation of flooring

Corus has developed a structural flooring system that uses thermal mass to regulate a building鈥檚 internal temperature. Airdek is a composite steel and concrete flooring system that works by bringing air into contact with the concrete slab. The thermal mass of the concrete then retains the temperature of the air and is later used to heat or cool the internal environment. Corus says that Airdek can eliminate or reduce the need for air-conditioning because cool evening air can be introduced to the slab passively through exterior vents (鈥淣ight-time purge鈥� digram, below). This is then released during the day through floor vents to cool the internal environment (鈥淧assive cooling鈥�, below). The system does allow chilled air to be introduced mechanically if the slab is not cool enough to reduce the room temperature during the day. Airdek鈥檚 structure consists of concrete poured on to a profiled metal deck that is supported by steel beams. An insulated liner called Coolduct from Kingspan Insulation is fixed to the underside of the steel profile to ensure that no cool air escapes to the interior below. Coolduct is used because of its ability to be easily shaped into the structural deck to form air ducts. The insulation means that the slab is cooled more efficiently as the air cannot escape. On ground floors where a ground-bearing slab is used, air can be introduced to the occupied space from the slab above. In this case, air has to be cooler, at 13掳C, than if it is delivered from the floor below, when it should be 18掳C. One benefit of Airtek is that the slab can be cooled without lowering the temperature of the inhabited environment, which means that the workspace can be used 24 hours a day. Another plus is that the system can take cold air deep into the plan of the building, where air conditioning would usually be required. As the air needs are catered for within the structural floor deck, Corus says that its system does away with the need for raised access flooring. This would have the advantage of either increasing floor to ceiling heights or reducing the floor-to-floor distance, allowing architects to increase the number of storeys in buildings. Corus also believes that the growth of wireless ICT will mean that less space will be required for cabling in the future. In the Airtek system, ICT cabling and power lines are catered for in a shallow trench cast in the surface of the concrete slab. The depth can be increased according to the client鈥檚 requirements. Another benefit is that by using a steel deck in the floor structure architects can also benefit from steel鈥檚 fast erection time. Corus has already built a mock-up of the Airdek flooring system and it is aiming to launch the system in spring 2004. Corus
