Unusual Bifolding Doors & Windows Installation in Hertfordshire

Barn doors on an outbuilding in the Hertfordshire countryside reveal a surprise when opened ... bifolding doors and windows from Luton-based manufacturer/installer, SunSeeker Doors.

Made to order to fit your exact requirements, our bi-folding doors have sturdy aluminum frames, BSI Kite-marked double glazing and a ten-year track record.

Slimline Bifolding doors and our UltraSlim slide-and-turn patio doors are both fully retractable. Their aluminium frames are available in a range of colours.

For interiors, we manufacture a frameless tempered glass door.

Slimline & UltraSlim Doors Sales and Installations

Owners of SunSeeker Bi Folding Doors benefit from our 10 years of development which has been carried through to our newer, innovative, retractable sliding doors products, UltraSlim and Frameless Glass Doors.

Despite the recession, our dedicated, hard-working team and many of our satisfied customers have helped to spread the word about our good quality, value-for-investment doors. Business has been steadily rising year-on-year and, so far, 2013 is no exception.

Thank you to everyone who is helping to make this possible.

A family run business based in Bedfordshire near the M1, SunSeeker Doors is a British manufacturer of aluminium framed bifolds and slide-pivot retractable doors.

Optional Extras with UltraSlim Doors

If you love glass but sometimes need privacy - or if you love the sun but occasionally it's too bright, we can supply UltraSlim doors with integral horizontal blinds, encapsulated within the double glazing cavity.

The blinds are worked by a magnetic 'pull' that attaches to the top of the doors, keeping the mechanism safe from over-zealous tugging - and the blinds NEVER NEED DUSTING!

Here is another UltraSlim door installation with 'wow' power - the horizontal bar detail was added to complement the style of the home. We think it looks stunning!

UltraSlim Doors for 10% more than Bi Folds

Our Slimline Bi Folding Door frames, at around 71mm (2¾") and with narrow profiles, has always been a market leader of contemporary doors but UltraSlim Door frames are 19mm (about ¾") at each side of each double glazed door, available in over 100 colour choices: white, black, silver, green, blue, sepia, grey and more.


Shown here is an 8-door UltraSlim Doors installation in a new extension, which has a viewing width in excess of 6.2m (approx 20ft) of glass interrupted by less than 27cm (under 11") of vertical frame. When all the doors are opened, there will be in excess of 6m of continuous access space between the house and patio, just like bifolds.

Unlike Bi Folding doors, UltraSlim door frames do not have hinges fitted, enabling us to reduce the frame width. The door on the right of the image will open just like a regular pivot door. Other doors are then able to slide along the guides to be positioned as required. To open more than one door, slide the nearest door towards the first (open) door and it will then pivot open in the same way. Repeat for as many doors as you require to open. You can have a pivot door at each end, if preferred.

Launched a couple of years ago, UltraSlim has rapidly become our best selling door and now we are able to offer this innovative product, made to measure and fully installed, for only 10% more than the price of our bifolds (compare door prices here).

Sightline Extra Large Glass Doors

Recently, Sightline Doors was launched to bring Extra Large Glass sliding doors to householders and owners of commercial premises who require large leaf glass doors. Each glass door has a maximum dimension of 3m x 6m, for extra wide or extra tall entrances.

There are two extra wide doors on this building. Either door may be opened with ease, creating ample room for people to pass through, several at a time! With the doors closed, there is a very slim sight-line as the side frames have only a 14mm width.

By contrast, the longer side of the glass  has been used to create height for the doors on this building - compare the height of the glass doors with the doors in the office wall inside.

Sightline extra large glass doors are available from SunSeeker Doors. We also install Slimline bifolds and UltraSlim glass doors.

A Warm Home in the Winter

This is not your usual "replace all windows and doors with double glazing" sales talk - we only manufacture glass doors (and not for front entrance doors, either). However, one of our clients who has our bi folding patio doors, told us that they really make the room warm whenever there is a glimpse of sunshine yet they are not cold to touch, even when it's cold outside ... and she likes the view through the bi folding doors.

As it's snowing today, we thought we'd pass it on. SunSeeker bi folding doors are made with thermally-broken aluminium frames and kite marked double glazing units; they exceed British standards for thermal values. SunSeeker bi folds can be installed between your home and conservatory, garden or balcony.

These clients have great views:

We manufacture all our doors in the UK and can often install in under four weeks. Feel free to browse our website and compare all our glass doors.
