Graham Holmes Astraseal launches flametek fire door

In commercial applications where fire doors are required - for example communal entrances, staircases and balconies designated as escape routes - specifiers have up until now generally had to choose costly timber door sets with associated ongoing maintenance costs rather than cost-effective, low maintenance composite doors and PVC-U frame and side screens which match the rest of the design scheme.

However, an award winning new PVC-U product from specialist commercial fabricator Graham Holmes Astraseal is set to change all that.

Astraseal has launched FlameTEK a half hour fire resisting composite door and side screen fabricated in REHAU’s S706 profile system which was named Innovation of the Year at the recent LHC Annual Awards. It is on display at the forthcoming CIH exhibition on Astraseal’s stand no 95, Hall B.

From 12 submissions received for the award from the 34 members of the LHC approved supplier network, FlameTEK was judged by Bruce Meechan, Editor of Housing Association Magazine as the best example of product design innovation.

The technology behind FlameTEK is based around the RAUFERNO product which REHAU itself launched in 1997. The company’s renowned late technical manager Dick Weatherall developed a way of using intumescent material - which expands in heat - to create a barrier utilising the frame reinforcement, fire retardant glass and door panel sufficient to fully comply with BS476 Parts 20 and 22.

The technology was well proven but for many years the application was limited to one specific door leaf.

However, demand from within the LHC and from other social housing providers for a PVC-U/composite fire door prompted Astraseal to re-examine RAUFERNO last year to see whether there was an opportunity to exploit the technology to create a volume product for this market.

FlameTEK is the result of the company’s investment in a major research, development and testing programme and it has patents pending on both its design and manufacture features. The new solution has been tested to BS476 Pt 22, received a 30 minute fire certificate from Warrington Fire Research and FIRAS approval for installation.

FlameTEK combines Astraseal’s composite door leaf with a side panel in the RAUFERNO fire resistant PVC-U system. It looks like a conventional PVC-U frame and composite door and has all the inherent benefits in terms of high security options, low maintenance and thermal and acoustic performance but it can safely be used for escape routes where a 30 minute fire door is required.

Since its launch, Astraseal has received orders for more than 1000 door sets from its partners in the social housing sector and has begun supplying to other fabricators and installers who have a requirement for small quantities of fire doors in larger projects.

As well as the LHC award, orders have been received from Crosskeys, Whitefriars and Walsall Housing Associations. Further details of the product are available from
