Slim frame - SF25f

Slim frame slide & turn - SF25f

The SUNFLEX SF25f offers slim non-thermal aluminium interlocking frames to emphasise your view with only slender aluminium edges.

An ideal product for all year round, keeping away the worst of the winter weather with minimum impact on a buildings design. During the summer months it can be opened completely to make the most of these precious times. 

This style of door has a single track and offers a single panel opening with then the ability to slide and stack all the remaining panels open. With slide and turn systems the panels are easily slid open around corners, with then all panels stacking to one or both sides.

  • Garden room/winter garden

    We all love sitting out in the gardens, but we spend very little time participating in this pastime due to our unpredictable weather. But what if we could increase those few days when we do to all year round.

    The SF25 framed is ideal for a garden room as when closed, this system provides you with a sight line of only 45mm. Allowing you to sit and enjoy your garden, even on the most cold and blustery days. And yet still retain the ability to slide and turn the doors away to fully enjoy those hot days, and carry on in to the evening when it gets colder. Simply slide the system back to continue enjoying your garden space.

  • Internal partitions 

    Whilst creating the glazed extension of your dreams you may wish to have the option of closing this off from the main living area. Alternatively if you are creating a kitchen/diner an option of separating the kitchen certainly has its benefits. The slide and turn SF25 framed would be ideal as it comes with a bottom track which can be recessed in to the floor for a near seamless floor level.

  • Balcony enclosures 

    A balcony area can be enclosed making this an extension of your indoor living space. A balcony can offer the best views from your property, but the variable climate we live in restricts the time you spend on there. A framed SF25 surrounding the top of your balcony wall not only helps to keep out the cold wind and rain. But also reduces the surrounding noise making the balcony feel more part of your home. This glass enclosure can then be completely opened up to take advantage of those warmer times.

  • The small top and bottom frames can be supplied as standard in any semi-gloss RAL colour, DB703 textured or silver anodised. Other colours can be sourced if required.
  • Interlocking panels offer a very slim 45mm sight line maximising your view and the light into your room.
  • Each panel can be left without a vertical seal to maximise the transparency of the doors or alternatively to offer a better seal against winds and for better sound insulation slim vertical transparent plastic strips are coupled to the glass.
  • Supplied with toughened glass either 6mm, 8mm or 10mm, depending upon height and requirements, available in clear, obscured or satinated. Other patterns also available.
  • Panel widths start from 300mm up to 800mm wide. Panel heights are from 500mm up to 2600mm.

  • Key lock can be provided in the top and bottom rail for additional security.
