Visofold 1000 Aluminium Bifold Doors
Aluminium folding doors with exceptionally slim sight lines of just 132mm!
Hartley Glazing bifold doors are manufactured from slim 60mm thermally broken profiles to ensure maximum glass widths can be achieved using the minimum number of panels. There are no additional mullions required between the panels that broaden the sight lines so when panels are folding sliding in the same direction the width of the aluminium from edge of glass to edge of glass is just 132mm.
There is a choice of weathered or low thresholds and with standard solar control double glazing and options such as our exclusive concealed trickle vent facility our Visofold 1000 aluminium bifolding doors have become our best-selling folding door.
Luxury aluminium folding doors
Our range of aluminium folding doors are manufactured from dedicated profiles designed by one of the UK’s leading architectural aluminium system suppliers Smart Systems. Smarts Visofold series of bifolding doors have been available in the UK and Europe for a number of years offering both domestic and commercial folding door applications.
Aluminium doors are particularly renown for their ease of operation and reliability in service and our doors also benefit from a dual roller system at the bottom with the panel tops also guided by rollers for smooth running and easy operation. There are no heavy-weight lintels required as the doors are bottom rolling and not hung from the top.
Individual door panels can be up to 1 metre wide to provide wide glass apertures using minimum aluminium profiles which allows natural light to flood into the room.
Fully Integrated Trickle Ventilation
Most bifold door installations will require trickle vents to meet building regulation requirements. Our unique and exclusive frame extender is designed to provide integrated trickle ventilation to your new aluminium folding door so the slim sight lines are not spoilt by ugly face fixed trickle vents. Fitted to the top of the door frame the profile conceals the trickle vents from view and also provides a weather bar feature to enhance weather protection at the top of the door.
Standard size bifold doors
In addition to a full made to measure service we also offer a standard size range of our aluminium bi folding doors which can save you up to 10% on our made to measure prices. Ideal for new build openings where you can construct the aperture to suit a standard size door you can still choose handle finish and door style as although they are standard sizes the doors are still made specifically to your order.
Bring the outside inside!
Add the WOW factor to your home and seamlessly merge your patio and garden with your new living space to create a visually stunning addition to your home.
Our aluminium bi-folding doors can be installed with flush threshold opening onto your patio or courtyard to provide a fully integrated door solution bringing the outside truly inside.
Low Threshold Option
The Visofold 1000 series features strong, durable profiles and a choice of low or weathered thresholds. The non-weathered low threshold provides the opportunity to create flush floor levels between two living spaces by sinking the threshold into the floor merging the two floor areas into one. This is particularly useful for internal doors between the main house and conservatory or as shown here between the kitchen and the outside decking.

Visofold 1000 folding sliding doors are manufactured from thermally broken aluminium profiles that are available in over 200 RAL powder paint finishes and can also be supplied with a dual paint colour finish so you can select an external colour and an internal colour.

Conservatory Bifold Doors
Aluminium folding doors are ideal for use as conservatory doors and are often requested by customers who feel aluminium provides a stronger durable door especially when wider openings are required. When fitted in conjunction with a steel portal frame doors up to 6 metres or wider can be fitted to open-up the complete front of a conservatory or as shown here two bifold doors can open up the corner of the structure with stunning effect.
