Wooden Folding DoorsThe SUNFLEX SF65 wooden folding door system has the slimmest sightlines in Europe. Unlike other solid timber folding doors the Sunflex SF65 is manufactured using triple solid timber sections, this prevents the warping and twisting associated with cheaper timber doors.
All timber is sourced from sustainable forests; standard timbers include Pine (knot free softwood) and Meranti (hardwood) while other timbers such as American White Oak and European Oak are avaliable on request.
Wooden Folding Doors Features
Minimal slim profile with excellent thermal properties
Flush track available ensuring level floor finish inside and out
Bottom running mechanism with ball bearing running carriages
Choice of Timbers – Available in a large range of stains and paint finishes
Standard glass – 28mm double glazed units, 4mm toughened glass, soft coat, argon gas & warm edge spacer
Overall system U Value of 1.4 W/m2K
Dimensions
We do not recommend panel widths exceed 1100mm and a maximum height of 2800mm. Heights greater than this can be achieved, please contact our technical department for advice. The Sunflex SF65 Wooden Folding Doors system is able to span opening upto 15mts in length and 2.8 mts in height.
 Operating system
The SF65 is available as a top or bottom running Timber Folding Doors system, consisting of wheels which are manufactured from tough glass fibre reinforced polyamide set around a maintenance-free sealed bearing, giving quiet smooth operation.
Track options
There are two choices of track on our Wooden Folding Doors; a standard stepped track for a severe weather rated system or an aluminium flush track recessed into the floor. This provides a level walkthrough with an uninterrupted floor finish.
Furniture
Handles and hinges are made of cast alloy, handles are sprung-loaded and flush-fitted to enable door panels to stack flat when fully opened. Optional lever handles are available upon request for single access door or lead doors.
Security
Where there are an odd number of panels, a five-lever profile cylinder is fitted to the end lead door or to the first opening pair in an even number of panels. Meeting the requirements of the Association of British Insurers.
Discreet finger safe gaskets
The gaskets (consisting of long-lasting EPDM) between the door panels and side jambs are continuous and have a unique chamfered design. This means that they interlock and form a highly efficient double seal.
Pull handles
When the folding door system opens externally the intermediate panels are fitted with a moulded ‘D’ shaped handle, this sits neatly within the gasket line enabling easy closure of the panels against the compression top and bottom gasket seal.
Ventilation
Trickle vents of either 2500mm2 or 5000mm2 can also be incorporated to the head profile to satisfy building regulations

Sunflex Wooden Folding Doors are manufactured in Pine (knot free softwood) and Meranti (hardwood) as standard while other timbers such as American White Oak and European Oak are avaliable on request.
The natural character of wood is perfectly presered by using a Sikkens micro porus wood stain or alternatively the timber can be paint finished to any Ral Colour
All handles are specially designed to complement the door system; standard colours are Black RAL 9011, White RAL 9016 or Silver anodised. Gaskets are in Black, with hinges mounted within seal sightline available in black or white. A Marine environment finish that is required to all systems within 5000m of a shoreline is also available.

What is a U-Value
A U-value is the measurement of the amount of the rate of heat loss through a material. The value is calculated as heat lost per hour per square metre (W/m2K); a low U-value therefore indicates a more thermally efficient building material.
Document L (Document J in Scotland) is part of the Government’s Building Regulations. Revised October 2010, following the Regulatory Impact Assessment, which controls the acceptable U-value of your home – in general terms, an average U-value of 1.8W/m2K is now required.
All new housing and replacement doors and windows must comply with Document L (Document J in Scotland), unless specifically excluded. If you are planning any new building or renovation work, it is always advisable to contact your local planning office for advice on how the building regulations affect you and your project. Although SKG London can offer general help and assistance based on past experience, we are not an authority on the building regulations and are unable to offer professional advice.
Low ‘e’ (Emissivity) glass
Our standard quotation includes the application of low ‘e’ (emissivity) to the inside of the inner pane that reduces the amount of heat loss through the glass. In addition, an inert argon gas can be added to the cavity between the glass sheets, thereby reducing the u-value by a further 0.15W/m2K. A ‘soft coat’ low ‘e’ (emissivity) glass represents a revolutionary development in so far as improved thermal performance providing an environmentally friendly solution, given the lower CO2 emissions associated with reduced energy consumption and a considerable reduction in heating bills, when compared to the tradition ‘hard coat’ low ‘e’ glass.
Warm edge spacer
Our standard quotation also includes warm edge spacer. Up to 80% of energy loss through a window occurs due to the spacer bar being a conductive material, a warm edge spacer reduces these thermal heat losses which is good news to the environment and even better news to you, further benefits include up to 70% reduction in condensation and improved noise reduction.
Solar control or comfort glass
The sun can make glass roofs, conservatories or south facing elevations quite unbearable in the depths of the summer months like stepping into a greenhouse. A solar control glass is a glass with a special coating designed to reduce the amount of heat entering a building. It reflects and absorbs heat as well as filtering light for reduced glare. Using a solar control glass can reduce the need for air conditioning and blinds. Please ask for further details.
Toughened glass
We include as standard a double-glazed unit comprising of 4mm toughened glass complying with BS6206. The glass has been heat hardened (tempered), increasing its strength over ordinary annealed glass by up five times. There is also an added advantage that, should it break, it would shatter into hundreds of tiny non-sharp fragments.
Laminated glass
The benefit of laminated glass is that, if broken, the glass cracks while still remaining attached to the plastic interlayer rather than falling and possibly causing injury; it also provides secure protection from unwanted visitors. In addition, laminated glass reduces bleaching of carpets, curtains and furniture by reducing the amount of ultra-violet rays that penetrate the glass.
Improved visual qualities
Due to the heat-tempering process used, 4mm toughened glass can sometimes suffer a slight visual rippled distortion. Although this is acceptable under British Standards, using 6mm toughened glass helps to reduce this distortion or 6.4mm clear laminate will eliminate the distortion altogether.

As specialist installers we have the experience, product knowledge and technical skills to ensure that your project runs smoothly and on schedule. We strongly believe that an important aspect to providing a high level of customer satisfaction is to minimise the number of different individuals you deal with throughout your order. On single and multi-orders you will be assigned a maximum of 2 contact people who will be assigned your contract and will assist you from initial estimate through to final installation and after sales.
Providing a quotation
We are able to provide a fast turnaround in preparing a quotation. For single and multi orders we will only require opening dimensions, these can be provided via our online estimate form, e-mail, telephone or fax.
We will provide you with the required technical information including detailed drawings of track, head and frame dimensions. We can arrange to visit you on site or you can visit our showroom to run through specification and the options available.
Contracts
Should our quotation be favorable we will need to arrange a site survey. During the survey we use laser-measuring equipment to take the necessary measurements required for manufacture, ideally both the building contractor and home-owner would be present. In most cases we will provide our contract and CAD drawings for your approval with 48 hrs. To order your doors we require a 25% deposit and the signed contract, an additional 65% is due 7 days prior to installation, the balance is due on the final day of installation.
For extra piece of mind we include an insurance indemnity with all of our orders.
Installation
You will be contacted at least two weeks prior to installation. Our installation team are all employed by SKG London allowing us to fully guarantee the quality of their workmanship, with complete confidence. Once your doors have been installed to your satisfaction and upon final payment, our engineers will explain the operating instructions, care and maintenance procedures, warranty and keys.
Guarantee
In the unlikely event that you encounter any problems with your installation, however small, we will always respond promptly and efficiently. Our insurance backed guarantee covers parts and labour for 5 years from installation date.
For clients who opt into our service plan we can extend the guarantee to 10 years. For as little as £20.00 per panel per year we will send an engineer to service the doors. Our service includes lubricating the running mechanisms, making any adjusting to the doors and testing the door hardware.
