At SlidingbiFolds we have developed a variety of internal sliding folding doors to meet the needs and desires of our clients; one system we use allows us to leave a 5mm gap above finished floor level which is perfect for disabled access or leaving any existing floor undisturbed.

We manufacture all our timber bifold doors in our own workshops to the very highest of standards. Each set is individually customised to your choice of engineered timber to ensure structural stability and prevent twisting or warping. All our timber is picked from sustainable, replenishable, monitored forests.

At SlidingbiFolds through past experience in dealing with different clients and their homes we realised there was a need for an insulated internal folding door system.  The main reason clients have asked for such a system is that their existing conservatory or sunroom looses a vast amount of heat during the winter months and causes the adjoining room or the rest of the house to feel cold during this period. In warm weather this can cause the opposite problem to happen and overheats the house.

We have spent time and investment, developing and creating an insulated internal bi folding door system that solves these problems.  Using double glazed units in a fully sealed bi fold door system we prevent the cold from penetrating during the winter months and reflecting heat during the summer months.

This is not only a more cost effective solution to replacing an existing conservatory or insulating a sun room but will add character and value to any property.

 SlidingbiFolds U Values 

 

Slidingbifolds has a hardware system for almost any internal bi fold door system.  We can use a range of different hardware systems to allow for top-hung or bottom-rolling that meets the needs of not only residential premises but commercial properties as well.   Most of our internal folding doors are top hung allowing a greatly reduced threshold or completely flush transitions between rooms. Where the structural head is not sufficiently secure to allow a top-hung system we can use one of our many bottom rolling systems.

Without the need for a bottom sill on some of our internal folding doors no costly tile or concrete cutting is required for installation. Based on SlidingbiFolds standard hardware system for external applications, it offers the same smooth operation and configuration flexibility.

EQUAL SIZED PANELS

Slidingbifolds innovative hinge system provides symmetry to the door design and simplifies the door manufacturing process.

NO FLOOR GUIDE

No sill (guide) means seamless transitions between indoor spaces and no costly tile or concrete cutting.

SIMPLE ADJUSTMENT

Easy screwdriver access and simple vertical and horizontal adjustment of the patented Surelock mechanism on pivots and carriers allows adjustment of 10 mm making our hardware the most practical system for folding doors.

DURABILITY

Tested to exceed 50,000 opening and closing actions at maximum load, without any component failure, we can confidently offer our 10-year warranty. 

INSULATION

Combining our state of the art hardware with recommended exterior weather-seals and double glazed units we can create an insulated internal bi fold door system.

SECURITY

Slidingbifolds systems incorporate locking screws, secure hinges and non-removable components. Our dropbolts are specifically designed for use with folding doors.  So are substantial, robust and lockable so door systems can withstand physical attack.

WALL PIVOT

The floating wall pivot is used to control normal door deflection on tall doors it also enhances security by reducing any leverage applied to door panels and preventing their removal.

 

A typical 3 Door Configuration

A popular choice for smaller openings, a 3-panel system like this ‘3 right’ layout provides a single access panel for entry from inside or outside just like a regular door. However, with fingertip-light operation, all three panels fold neatly to one side allowing for more open living space.

 

3 Door Configuration Min width 1500mm – Max width 3000mm, Max Height 3300mm

All configurations show outward opening doors but inward opening configurations are also available

4 Door Configuration Min width 2000mm – Max width 4000mm, Max Height 3300mm

4 Doors All one Way

.The layout of this typical 4+0 or ‘4 left’ configuration offers a clean external appearance. It can be designed to match the sight lines of any glazed gables. Plus you benefit from even more impressive system stability, because concealed hardware anchors the panels on both sides of the opening. Once closed they are totally secure, with no access from outside.

3 Doors Left One Right

An alternative option to a 4-panel one-way system for wider openings, a typical 3+1 layout like this ‘3 left, 1 right’ option has an access panel that allows entry from  inside or outside just like a regular door. Of course, it could also be ‘1 left, 3 right’  if you prefer. The panel next to the access panel is secured with a Twinpoint lock and both sets of panels fold neatly back to stack against both sides of the  opening when the doors are fully opened.

5 Door Configuration Min width 2500mm – Max width 5000mm, Max Height 3300mm

5 Doors All One Way

A 5-panel one-way system like this typical ‘5 right’ layout is often used to open up an entire wall of a home to the outside environment. This configuration provides an access panel for entry from inside or outside, just like a regular door. All panels can then also fold neatly and smoothly back to one side, stacking against the wall to maximise your available living space.

Three Doors Left Two Right

For a wider opening, perhaps even an entire wall of a room, this typical 3+2 configuration or ‘3 left, 2 right’ layout is ideal. With an access door built in to either the left or right, depending on your specification it allows entry like a regular door when the doors are fully closed. However, they can also be partially opened to either side – or fully folded back, stacking flat against both sides of the opening.

Each door and frame will be machined and joined in our workshop, using our unique engineered timber to prevent warping and twisting. A wide range of timbers are available, as standard these include; Pine, Mahogany, Iroko and Oak. Other hardwoods are available on request. The most common type of internal bi fold door will be one that is fully glazed.  This is known as a Pattern 10 door which is shown right.  As each client has their own individual tastes we can make any type of door whether it is a full timber door or partially glazed, we can also match the existing doors of a client’s house to keep and preserve the traditional look.   

Door frames are be made from an appropriate hardwood to match the door construction. The construction of the frame will vary depending on drive track (top or bottom) depending on the opening requirements.

We offer an almost infinite range of finishes to suit your individual preference, each coat expertly applied in our fully equipped spray shop.

Quality Assured

The entire process is under the control of our team of experienced joiners ensuring that each finished product leaves our workshop fully factory finished, wrapped and ready for installation.

  Slidingbifolds Pattern 10 door

Your new timber bifolding door is supplied fully factory finished in your choice of translucent stain finish or sprcified RAL colour. To maintain the integrity of the product it is important that all timber bifold doors are factory finished. Many suppliers offer an unfinished product which means you are responsible for applying at least three coats of wood stain or paint which can be very time consuming and could compromise the warranty if not applied correctly.

Standard Spray Finishes

Our timber folding doors are factory sprayed with three coats of 250 microns per coat which provides a finish comparable with up to 15 coats of brush applied paint. Factory finished doors are low maintenance and have a very long life span of up to 10 years before they require attention.

Translucent Stain Finishes

Choose from a translucent wood stain from the Morrell’s wood finishing range which provides a high quality finish whilst protecting the timber against every day use.  The natural colour of the wood can be perfectly preserved by using Morrell’s 2 pack lacquer, which is available from 10% sheen (deep matt) to 90% sheen (high gloss) in a variety of different wood stains.  We have a sample range that we can post to you before confirming your order

RAL Paint Colours

Alternatively, you can also choose from over 200 different RAL colours available in matt, satin and gloss finish. You can download a RAL colour chart here for guidance purposes but we recommend you obtain a printed RAL colour chart to confirm your colour choice at the time of order. A few RAL colours may require an additional set-up fee, please check with us prior to ordering. Morrell’s also offer the Fastmatch Colour Matching Service to meet our customers’ colour matching requirements so we can match your existing decor.

 

Depending on the requirements and design of your interior bi folding door we offer a wide range of possible timber and glazing options. As standard in our most common internal bifold door we use 6.4mm laminated (safety glass). This can come as clear, tinted, sandblasted and obscure. To view all the possible colour configurations please click the link . If the internal folding doors are required to be insulated we can use our standard Low-E double glazed units (1.2 U-Value).

We use PLANITHERM

PLANITHERM is Europe's best selling range of high performance low-emissivity glass (low-E glass). The glass utilises the very latest advancements in thermally insulating glass coating technology.

Specially manufactured by Saint-Gobain Glass for the UK market, PLANITHERM products are specifically designed to keep interiors more comfortable in the winter months and improve your home's energy efficiency.

The thermal insulation provided by low-E double glazing is three times more efficient than that of standard double glazing and PLANITHERM products are the ideal low-e solution to meeting and exceeding the newly revised Building Regulations energy efficiency requirements.

 SlidingbiFolds Laminated Glass

PLANITHERM products use a special coating to reflect heat from domestic heat sources back into the room, rather than allowing it to escape through the windows. At the same time, this coating allows free heat and light from the sun to pass through the glass, warming the room and further contributing to the energy efficiency of the windows and helping to reduce your energy bills.

Additional Options

The PLANITHERM range can be combined with many other Saint-Gobain Glass products, providing a multitude of high performance, multi-functional glazing options, including:

 • Self-cleaning and/or solar control glazing
 • Acoustic insulation
 • Obscured and/or decorative glazing

This combination of excellent thermal insulation with high solar heat gain makes PLANITHERM the most energy efficient window glass available and the best possible choice for energy savings
