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.
Sound effects on timber frame
The UK Timber Frame Association is planning to publish a guidance document to Part E of the Building Regulations later on this summer. It will give detailed technical guidance on designing Part E-compliant timber construction details.

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.
