How do your systems compare on price, quality and reliability?
Sunflex folding sliding doors are designed and manufactured in Germany to the highest of standards and have been supplied to many countries throughout the world for in excess of 15 years. Recognised as setting the benchmark in both design and technology, the standards of our product testing far exceed those required by the British Regulations, i.e. weather rating, insulation, safety and security.

What are the standard sizes?
All Sunflex doors are made to measure; as such there are no standard sizes.

What are the restrictions on maximum width and height of the panels?
The maximum width of each panel is 1100mm and the maximum height is 2800mm, however, we do not manufacture to both extremes in one panel. The taller the panel, the narrower the width, please contact us for advice.

What is the maximum number of panels I can have?
There is no limit to the number of panels you can have, but we generally recommend a maximum of 25 meters (12 panels in any one direction).

How much do they cost?
As each system is custom-manufactured, it is always difficult to provide an accurate estimation unless a quotation is prepared. However, for approximate budgeting purposes, a cost of £1,200.00 - £1,600.00 per panel, supplied and fitted exclusive of VAT can be assumed based on average door height of 2100mm and panels of around 1000mm wide.

What different configurations are available?
There are a large variety of different opening configurations available. For more information on the different opening variations (click here)

Have your systems achieved a severe weather rating certificate?
All Sunflex folding sliding doors systems have been rigorously tested and provide a severe weather rating when used with the weathered track option.
(Tested at the Institute of Window Technology Rosenheim: achieving DIN18055, Category C performance for wind loading and water leakage). You should only trust certified systems that have been laboratory tested.

Does your system enable a level floor finish for disabled access?
The flush track option is recessed into the floor providing an uninterrupted floor finish. The bottom seal between the door and the flush track is via double, twin nylon brush piles separated by a fin seal, giving an effective seal. It is recommended that some form of drainage and a slope away from the doors are integrated ­ such as a sunken drain with a grill above ­ to avoid pooling of water. Please be aware that the flush track reduces the weather rating.

How secure are your doors?
The locking offered as standard provides a very high level of security as well as a quick, smooth and easy operation. It consists of a three-point top and bottom shoot bolt mechanism, which is incorporated into the framework within each intermediate panel. For improved security, all Sunflex folding sliding door systems are internally glazed as standard with interlocking gaskets.

What are the restrictions on maximum width and height of the panels?
The maximum width of each panel is 2500mm and the maximum height is 3000mm, however, we do not manufacture to both extremes in one panel. The taller the panel, the narrower the width, please contact us for advice.

General Questions

How do I obtain a quote?
There are a number of options. You can either fill out our online estimate form and someone from SKG will e- mail you a full written quote based in the information provided.

Alternatively you can sketch some dimensions and/or extra details you may have and fax or email them to us.

Can you colour match any existing doors and windows?
Whether you currently have aluminium or timber we offer an extensive range of over 300 colour finishes, including dual colour.

What warranty do you offer on your door systems?
With the quality of our products, combined with a high standard from our installation team, we are able to provide a full five-year insurance backed warranty on our systems and workmanship, ensuring complete peace of mind.
Plus, unlike some warranties, our guarantee is fully transferable. If you decide to sell your home, the new owner benefits from the remainder of the guarantee period. (Please note that supply-only doors carry a full one-years manufacturing warranty.)

Can you make windows and fixed frames to match your door systems?
Whatever type of door system you choose, we can also manufacture single doors, French doors, tilt-and-turn windows, fixed glazed screens or even gable ends using matching profile sections to achieve an aesthetically uniform appearance throughout.

Do you offer supply only, and are the products easy to install yourself?
Yes we do; and we can supply full installation instructions. Please be aware that we offer a one years warranty with doors purchased on a supply only basis, as we have no control over the quality of final installation.

Do you offer an insurance backed guarantee?
Yes, all of our installations come with a five year insurance backed guarantee as standard.

Do you do site surveys?
Yes we can carry out a site survey and this will be included in our price and not as an extra like many other companies do.

What do you mean in your quotation, by fitting to a prepared opening by others?
We do not undertake any structural building work or removal of existing doors or windows and, therefore, the opening would need to be fully prepared by a builder prior to our installation engineers arriving to fit the doors.
For quotation purposes it is assumed that the installation location is a ground floor level, unless otherwise specified.

What methods of payment do you accept?
A 25% deposit with confirmation of your requirements, with the balance due on delivery or installation (depending on how the doors are being purchased). Payment can be by cash, cheque or BACS transfer. Please note for all orders over £20,000 will require an interim payment of a further 50% prior to installation although we do reserve the right to alter payment terms of any order value subject to status and authorized credit worthiness.
