Synseal-Improved-Patio-ImageSynseal’s popular patio doors have benefited from a series of profile design improvements in preparation for the 2014 home refurbishment season.

In response to customer feedback, a new fitter-friendly J-bead has been introduced to make site glazing of Synseal patio doors both easier and quicker.

The PVC-U patio sliding sash profile has been redesigned with an internal web added to create a triple-chambered design for greater thermal efficiency. This also improves the U-value for a standard patio glazed with 28mm double glass including aluminium spacer bar from 1.6 W/m2K down to 1.5 W/m2K. The central chamber houses a 2mm steel reinforcement to give increased rigidity and an external drainage slope has been added to efficiently route rainwater to the concealed drainage slots and optimise weather performance.

While patio doors with external sliding sashes will always remain the most popular specification, an internal slider option has now been added to cater for occasional market demand.

The new improvements are completed by low threshold options in thermally-broken aluminium, to provide a comprehensive range of access solutions for Synseal patio doors.  Available in a choice of Gold or Silver anodised finish, these sturdy aluminium low thresholds can be selected with an internal trim and external ramp, as well as ramp/ramp and trim/trim configurations. Compared to a standard PVC-U sill, the new low threshold designs lower the step-over height by 47.5mm, ensuring ease of access for all the family.

Mark Schlotel, Synseal’s Head of Marketing, commented: “These profile design improvements will be introduced from February 3rd 2014 and are certain to be welcomed by all our many patio door customers, from bar length fabricators to purchasers of door kits and Evolve range patio door units, which are fully-manufactured and CE Marked by Synseal.”
