DK Window
In ventilation position, the window tilts inwards from the top and stays slightly open, creating a pleasant flow of fresh air. When you want to ventilate the room, you do not have to remove things from under the window or from the windowsill. And, thanks to its design, the window keeps rain out even when tilted for ventilation.
For easy cleaning, these windows can be opened inward to the side. Because there is only one frame, there are just two glass surfaces to clean. When closed, the window is locked securely with a multi-point locking mechanism.
Our DK windows are also suitable for use as French balcony doors, for instance. The single-framed window swings open in the same way as a door and has the added benefit that it can be tilted and left in ventilation position. This kind of ‘door’ is safe for children and pets even when it is left slightly open.

Our fixed windows can be manufactured with any of three types of wood.
Close-grained premium-grade pine is a hard-wearing wood that does not shrink or expand when the temperature changes. We cut all pine along the grain, which brings out the texture of the wood beautifully, enhancing the appearance of the window frame.
Siberian larch is an excellent choice for humid and damp conditions, because the wood contains natural agents that prevent decay. The surface of larch wood is hard and very durable. Larch has traditionally been used in such applications as shipbuilding.
Finally, oak is a stylish and hard-wearing wood. It does not shrink or expand, and its high density makes it extremely durable.
Handles
Window handleStandard handles. We use Hoppe handles in our windows and doors. Our standard handles are from the Hoppe New York range and are available for all of our windows and doors. Other handles are available on request.
Glazing
Float glass
The name of float glass refers to its manufacturing process: the molten glass is floated onto a bed of molten tin and onto a cooling kiln. The manufacturing process enables excellent optical quality in the result. The most common float glass thicknesses are 4, 6, 8, and 10 mm.
Tempered glass
Tempered glass is physically and thermally strong, and it has excellent flexural strength. It is around 4–5 times stronger and more heat-resistant than non-treated glass. When tempered glass breaks, it shatters into small, dull pieces instead of sharp shards. Most types of glass can be tempered, except soft-coated glass and carved decorative glass.
Laminated glass
Laminated glass consists of two or more sheets of glass with inter-layer bonding, typically of polyvinyl butyral. When laminated glass breaks, the inter-layer structures hold the pieces of glass together, preventing injuries caused by falling or flying glass. Various types of glass, including energy-saving, sun-protection, and soundproof glass, are available laminated.
Safety glass
Safety glass is designed to prevent injuries from falling or flying glass. There are two types of safety glass, tempered and laminated glass, with individual subtypes of glass falling into personal safety classes F1–F3. Some types of safety glass can also have other features, such as energy-saving properties, protection against the sun, or soundproofing.
Selective glazing
A product with selective glazing is coated with a thin layer of metal that allows short wavelengths to pass through the window while reflecting long wavelengths. Selective glazing can reduce heat loss by up to 70%. The soft coating scratches easily, so the coated surface always faces the inside of the glass unit. Double-glazed units typically have one coating on the inner pane, while triple-glazed units have both the inner and the outer pane coated.
Sun-protection glass reduces the amount of solar radiation that passes through the glass unit. The thermal radiation and visible light from the sun is partly reflected and partly absorbed, with only some of the radiation passing through the glass. Sun-protection glass can also be tempered, or it might have features such as soundproofing. The pane with the sun-protection coating is always the outermost pane of a glass unit. The special coating on energy-saving sun-protection glass scratches easily, so it always faces the inside of the unit.
Safety glass can be used to protect people or property against vandalism, break-ins, or firearms. Resistance categories:
- Anti-vandalism P1A–P4A
- Protection against burglary P5A–P8B
- Bullet protection BR1–BR7
The safety feature can be combined with other features, such as energy-saving properties (selectivity), protection from the sun, or soundproofing.
The soundproofing characteristics of a glass unit can be improved through the use of panes with different thicknesses, by means of laminated glass, or with an increase in the amount of space between the panes. The best results are achieved with laminated glass that has a special soundproofing coating. Soundproofing glass can also have other features, such as energy-saving or sun-protection properties, or it can be tempered, for example.
Silk-screen and back-painted glass. Tempered silk-screen or back-painted glass is an excellent choice for portions of façades that do not have windows. The colours for back-painted glass are chosen from the RAL colour chart. Decorative patterns are created to order, by means of the screen-printing technique.
Insulated glass units Most of our insulated units feature Super Spacer warm edge spacers. The Super Spacer component is made of silicone foam without any metal parts, and it is a significant improvement over traditional metal spacers. It conducts 950 times less heat than aluminium spacers do and has been shown to reduce the pressure on the panes, decrease the passing of heat through the unit, prevent condensation, increase the surface temperature of the panes, and improve soundproofing. The Super Spacer product has undergone extensive testing, and it is widely used all over the world
Insulated glass units with Super Spacer warm edge spacers have the market’s best U values. Super Spacer spacers enable window- and door-manufacturers to meet tightening energy-efficiency requirements.
In addition, spacers made of aluminium or stainless steel are still available. Metal spacers can be used when the spacers have to be a certain colour or the glass unit must meet the requirements of a specific fire-resistance class.
