With changes to the Building Regulations and European Standards looming, we take a look at the products on the market that are already up to scratch
Disabled-use fire doors for health buildings
HA group of UK manufacturers has produced a set of product specification packages for fire doors. The partnership called Build for Health has devised the solutions to help designers specify the most appropriate combination of door components for healthcare buildings.

The construction details are designed to meet the Disability Discrimination Act, BS8300:2001 and Part M of the Building Regulations. The companies involved include Dorma Door Controls, HEWI, Kaba Door Entry Systems, Lorient Polyproducts, LS Leaderflush Shapland and Royde & Tucker. Build for Health is concentrating on offering specification guidance to designers working in NHS LIFT schemes. In the future, it aims to expand the scheme to other sectors, such as schools and legal buildings.

European-standard fire doors
Door manufacturer Shadbolt has tested all its doors to the first part of the new BS EN 1634-1: 2000 standard. Shadbolt claims it is the only UK manufacturer to have tested all its fire doors to the European standard, which will eventually replace BS 476: Part 22, according to the company. The fire test exposes the door to a higher temperature for a longer period of time. Parts 2 and 3 of the standard, dealing with hardware and smoke control doors, have been drafted but not yet ratified. The recently published amendments to Part B of the Building Regulations state that doorsets tested in accordance with BS EN 1634-1 will be deemed to satisfy the relevant parts of the Building Regulations.

Advice on thermal conductivity changes
Kalzip has published a booklet on the new thermal insulation measurement Lambda 90/90 and its impact on Building Regulations. One of the effects of the new European Construction Products Directive, due to be implemented later this year, is that the quoted thermal conductivity value (lambda value) of insulation products will be lower because of a new method of calculation – Lambda 90/90. This means that insulation must be increased to ensure compliance with Part L of the Building Regulations. Every type of insulation is affected and the Kalzip technical department has made sure that all its insulants comply with the new requirements.

Concrete floor goes down well with Part L
Tarmac Topfloor has launched a new pre-cast concrete flooring system to help housebuilders meet Part L of the Building Regulations. FastFloor Heatsave consists of a suspended flooring solution using pre-stressed concrete T-beams, infilled with expanded polystyrene (EPS) panels. Topfloor claims the EPS panels (which replace normal lightweight concrete blocks) enables the flooring to attain U-values of less than 0.25 W/m2K and negates the need for further floor structure insulation. Topfloor says the flooring system can simply be topped up with a power-floated C35 concrete topping, which is reinforced with an A98 mesh or fibre. The floor is completed with a 75 mm screed.

Acoustic regs guide from Thermalite Aircrete
manufacturer Thermalite has published a guide to Part E of the Building Regulations. As well as containing a summary of the principle changes in Part E, it also presents details which Thermalite says can be used in new dwellings to comply with the changes in Part E. There is also a section on the House Builders Federation's Robust Standard Details programme, as well as detailed drawings of three separating wall Candidate RSDs that include aircrete blocks in their construction.

Steel use guides for acoustic performance
The Steel Construction Institute is publishing three articles to help designers using steel meet the requirements of the Part E of the Building Regulations. Guides covering the acoustic performance of light-steel framing, of Slimdek and of shallow-deck composite floors will be available in the summer. They will be available from SCI publications on 01344 623345 and at the websites below.

Kent homes tested for noise insulation
H+H Celcon has been carrying out acoustic tests on homes on Kent to prove its aircrete products comply with changes to Part E of the Building Regulations. The tests at a Hillread Homes site in Kent showed an average sound insulation of 53 dB, says to Celcon.

Priorsford Court, Peebles

These apartments in Peebles, Scotland meet the latest version of Part E of the Building Regulations, according to the Stewart Milne Group. Priorsford Court in Peebles consists of three blocks of 12 two- and three-bedroom apartments, which were built using timber walls and floors from Stewart Milne. The floor construction consists of a prefabricated floor cassette with I-beam flooring components and 70 mm acoustic floor battens. To prevent the transition of noise between floors, the plasterboard resilient bars are used to decouple the ceiling from the floor cassette. Stewart Dalgarno, managing director of Stewart Milne Timber Systems in England and Wales, says “the combination of mass, decoupling floor depth and design“ provides the floors with their high level of acoustic performance and enables them to exceed the new requirements of Part E. Dalgarno says it has been building these types of constructions in Scotland for 10 years to meet the requirements of the onerous Scottish Building Regulations, where testing has been in place for some time. The company is hoping that its new £10m factory in Witney, Oxfordshire, will enable it to increase its market share for timber walls and floors in England and Wales when Part E of the regulations comes into force on 1 July 2003.

CPD-compliant thermal insulation

Knauf Insulation has introduced a range of new CE-marked thermal insulation products fully compliant with the Construction Products Directive 89/106/EEC. In response to the standards, the company has launched a range of higher specification products, including new Crown Dritherm Plus – a glass-mineral wool cavity wall insulation – in 75 mm, 85 mm and 100 mm thicknesses. There is also now a higher 140 mm specification for Crown Factoryclad Plus, a high-strength glass-mineral wool product for the thermal and acoustic insulation of roofs and walls of profiled metal clad buildings. The existing Crown Factoryclad range will also now be available in a greater range of thicknesses up to 200 mm. Knauf has launched a new booklet explaining CE marking and the requirements of the directive. Knauf Insulation
