aluplast has continued its investment in the UK window and door industry with the launch of a new slim-sightline and modular PVC-U flush casement.

Defined by a slim-sight line chamfer to the IGU, the new aluplast flush sash maximises the glazed area of the window.

Designed to integrate seamlessly with the German-system house’s Ideal 70 and Ideal 4000 systems, it features a choice of standard and heritage, deep bottom rail, increasing its appeal among owners of period properties, while also minimising additional stock holding.

This includes integration with aluskin, aluplast’s highly innovative external aluminium cladding system for the contemporary SquareLine Ideal 4000 system, allowing fabricators to replicate an aluminium flush casement in an energy efficient PVC-U system.

aluplast has also used the launch of its new flush casement to unveil its new ‘pencil-line’ welding technology. This allows fabricators to deliver an ultra-fine 45°weld using standard welders through aluplast’s investment in specially developed welding blocks.

Seamless welding technology has set a new standard in window and door manufacture – but that takes investment and investment that’s not going to be accessible to every fabricator. The new sash can be either mechanically jointed or with this unique new welding block technology, which allows fabricators manufacturing the flush fit sash to achieve a 45°weld with an ultrafine joint, using their existing welders.

This leaves a very thin pencil-line joint, which doesn’t require penning on foils – it’s a premium finish for a very small investment compared to the outlay that accompanies seamless welding technologies.

In addition to aluskin, aluplast offers a range of 27 ex-stock and special colours on lead times of 15 working days or less.
