What makes an internal door into a Josko top product? Josko internal doors are the trend setters in the market but we also meet the standard in terms of quality of workmanship and materials. For example, all Josko doors include a stable core of flax and therefore have many good properties by nature.
In addition, Josko uses edges and veneers made of real wood rather than plastic edges and patterned foils. You can choose any height and width – in increments of one centimetre, for every Josko door is an original and is manufactured to your specifications. People who carefully examine all required external and internal virtues of an internal door choose Josko.
Internal doors with a core of chipboard and paper honeycomb fail to attain the requisite "internal values".
A 40 mm Josko door panel incorporates a central layer of robust flax. This natural raw material is extremely fast growing and is therefore both an ecologically friendly and an economical material. In addition, it is durable and therefore an outstanding insulating material. Thus Josko internal doors make a valuable contribution to climate protection and score high in terms of longevity and good acoustic and thermal protection.
Over time thin veneers or foil edges can come loose at exposed points.
Josko protect their internal doors with solid, patented slotted glued edges. The real wood edges are produced with the ideal thickness, which prevents them from jutting out and coming loose. In this way wood, the most natural of construction materials, increases longevity and visual appeal if used intelligently.
Many internal doors are only coated with wood-pattern decorative foils made of plastic.
Josko make exclusive use of high-quality real-wood veneers for their interior doors, because no other material can imitate the beauty of real wood. In the "Exclusiv" design series all of the veneers are taken from a single tree trunk. Depending upon the type of wood used, about 6 to 15 door panels can be manufactured from a single trunk.
Most of the time the outer layer of an internal door is only made of medium-density fibre board (MDF) or chip board.
Josko uses high-density fibre board (HDF) for their outer layers as standard. This material is less sensitive to pressure points due to its greater hardness and, because of its higher moisture resistance it is also the ideal protection against door warping.
Door panel widths available in 5 cm increments cannot be called "variable".
Josko internal doors accommodate your requirements perfectly, namely in increments of 1 cm and that at no extra charge. It is not necessary to cut the door panel and frame or to modify the wall. Above all this makes them attractive in terms of conversions or renovations.
Of course the utility aspect is most important when it comes to security doors. But we at Josko think that this aspect need not be visible.
At first glance there is nothing to indicate the concentrated strength of the Securance security doors. Instead of the usual frame design for security doors, Josko can produce them in flush or wall-flush design. In addition you can realise your stylistic ideas with inlays, strips or RAL paints.
