Folding-sliding (outward opening Bi-Folding doors) let large surfaces to be simply swept aside. The door parts fold on hinhes on one side: to the exterior. They are ideal for generous living spaces, or for conservatories and vary large areas. Whole glass wall may be almost entirely opened while the indywidual elements are folded and pushed aside to the left or right into a corner.
Folding sashes lok just like outward opening Casement or like traditional Sliding Sash windows. The folding sashes have almost identical glazing beads.
Bifolds are folding sliding doors that open up an entire wall to really give your home the wonderful “outdoor-indoor” feeling all year long. The design is able to support panels weighing up to 150kg with precision and ease. A maximum of 6-8 equal size panels can fold seamlessly in each direction in a number of different configurations while doors can slide either inwards or outwards.
Our bifold doors are secure and safe. Our internal beading, shoot bolt and cam locking mechanisms will provide solid barriers against forced entry. Don’t risk the security of your home and family – make sure the doors that you buy make you feel safe and sound at your living place.
We supply windows manufactured from multi-layered laminated woods in Mahogany and Pine designed not to twist or warp. Other woods including oak and larch will be supplied for special projects where the volume is of sufficient size to not make the cost too prohibitive.

Joinery is painted with water base, ecological, transparent or opaque Teknos varnishes. As standard, the inside and outside color are identical. We paint with coating paints and on the so-called stains, or paints that make the wood structure visible. The basic covering colors are white (according to RAL 9016) or brown (RAL 8017). Others are available for a small additional fee. We do not use surcharges for orders for a larger amount. The covering color should be determined according to the RAL or NCS template. In special cases, the colors are selected individually.
We present the stain colors below, but the actual coloration may differ from that of the monitor. Stain colors are divided into price groups and are presented below; on every type of wood, the same stain color is slightly different. It is possible to paint in a way that a different color is inside and a different one outside. This method of painting is called bicolor. It is required to specify which color to be on each side.
