The new, highly insulated Sunflex SF75 is the market leader in folding sliding doors. It sets new parameters of insulating levels in folding door systems without compromising comfort or design. The slim profile of the frame matches that of the SF55 doors which enables maximum light into spaces. The frame on the SF75 has an extra 20mm depth, enabling the use of 48mm triple glazed units and a 44mm thermal barrier; this is where the higher levels of insulation come from.

 

The advanced technology used ensures that not only does the SF75 exceed current building regulations but any other likely stringent changes in the future.

Operation

Designed predominately to be bottom running, the stainless steel running mechanisms consists of four wheels, manufactured from tough glass fibre reinforced polyamide, set around a maintenance-free sealed ball-bearing, giving a quiet, smooth operation with optimum resistance to extreme weather and temperatures fluctuations. Each wheel and guide mechanism can carry up to 200 kilograms.

 

The advanced pioneered technology in this system is designed to be completely fitter friendly and upon installation enables the height of the system to be easily adjusted with the simply use of an Allen key.

 

Self-lubricating collar type bearings provide quiet operation without squeaking hinges.

 

There is a vast range of different configurations the SF75 can be made in &  the doors can either be opened to the inside or outside.

Profiles

The Sunflex SF75 is the most thermally efficient system in the market, triple glazed as standard provides an overall u-value of less than 1.0W/m2K. Narrow sightlines ensures maximum glass area and contemporary styling, without compromising the severe weather rating.

 

The aluminium frame profile is constructed from a strong aluminium extrusion, which has been thermally broken by a 44mm polyamide insulation bar, guaranteeing it optimum resistance to combat heat loss and condensation. The minimal framework is offered as a (WE) square edge profile.

Security

A high level of security is provided as standard, with an effortless, quick, smooth and easy operation. It consists of a two-point top and bottom shoot bolt mechanism, with additional central locking point to end lead door.

 

The locking system is incorporated within the framework within each intermediate panel, operated by an internal flush handle. The shoot bolt rods are manufactured in aluminium and linked by a corrosion resistant cam. In addition, they are capped with polyamide cones that prevent any metal damage to the tracks when locking, whilst compressing the panels tight against the top and bottom seals.

SF75c

The SF75c is, at heart, the same product as the SF75 but with one difference - timber cladding.

 

With timber cladding on the internal faces of the doors, a truly natural, warmer feel can be achieved by finishing your choice of timber in a natural stain. Pine or Meranti timber is available.

 

On the timber cladding there are two types of milling finish - either a rounded edge or a straight edge.
