Timber Stormproof Windows

timber_stormproof_windowsOur stormproof timber window range has been developed as a truly versatile window that can easily be adapted into many differing situations.

The below specification details our timber stormproof window system. A range of cill, frame thickness, finish and ironmongery options are available together with your choice of sash option making this a highly bespoke product. Stormproof windows are supplied with ovolo edged sashes (except where decorative horns are required) and ovolo beads as standard. Square edged sashes, round beads and putty line beads are optional on written request.

Locking System

Utilising mushroom bolts and shootbolts, our standard espagnolette locking systems have achieved more than 7.4Kn – more than double the requirements of BS7950. They have also been endurance tested to 40,000 operations and have been salt spray tested for 500 hours by the BBA.

Friction Stays

We utilise the benefits of two different friction stays in our timber stormproof window range. All our top-hung windows and side-hung egress windows use a hinge that is manufactured in the UK and available as austenetic for enhanced corrosion resistance. For our heavier side hung sashes, we use a heavy duty hinge ensuring that the product will perform for many years to come.

Drainage

All Dempsey II timber windows are dry gasket glazed, with either sloped or concealed drainage systems. This ensures any moisture that penetrates the external glazing seals has an escape route and therefore eliminates standing water from the rebate thus significantly reducing the risk of rot, warping etc. For more extreme locations, there is the option to upgrade the bottom bead to an aluminium section thus further significantly reducing the risk of moisture ingress.

Energy Efficiency

Our timber stormproof windows are registered under the window Energy Rating Scheme. We currently are able to offer our customers the most efficient products available under this scheme – an “A” rating. This is available on the innovative Accoya timber species.

BS 7950 Security

Our externally beaded European Redwood timber stormproof casement window has achieved the standard of BS 7950 at Trada’s UKAS accredited test house. This window benefits from thicker timber profiles and anti-jemmy hinge devices.

Secured By Design

By utilising our BS 7950 security window and upgrading the glass in many circumstances to laminate, our timber stormproof window meets the requirements of Secured By Design. To ascertain project specific Secured By Design requirements, we offer a service that includes liaising with both the client and the Crime Prevention Design Advisors (Architectural Liaison Officers) to ensure that the specific specification requirements are met.
