Tilt and Turn
Tilt and Turn
Tilt & Turn windows combine functionality with security. All functions are one-handed, one move operated.
It is smooth, easy and safe. The multi-point locking mechanism also keeps the sash/frame from twisting or bending.
Using the most advanced manufacturing techniques, the windows and doors are manufactured using laminated and finger jointed sections of carefully chosen timber. This method of manufacture eliminates knots and other imperfections, reduces wastage and increases the rigidity and quality of timber, providing a high quality finish to the product.
For the manufacturing of wooden windows only timber from sustainable and environmentally managed forests will be used.
Following types of wood species have been specifically chosen for our windows:
Main hardwood for our BALTwin windows
Main softwood for our BALTwin windows
High quality finishes are specifically designed for each particular wood species, protecting the wood from harmful UV rays as well as enhancing the natural character.
- high quality stains
- micro-porous paints
- environmentally friendly REMMERS products

Annealed Glass -
is the basic flat glass product that is the first result of the float process. It is the common glass that tends to break into large, jagged shards. It is used in some end products -- often in double-glazed windows, for example. It is also the starting material that is turned into more advanced products through further processing such as laminating, toughening, coating, etc. “Ref: Glass for Europe”
Toughened Glass –
is treated to be far more resistant to breakage than simple annealed glass, and to break in a more predictable way when it does break, thus providing a major safety advantage in almost all of its applications. “Ref: Glass for Europe”
Toughened glass is made from annealed glass treated with a thermal tempering process. A sheet of annealed glass is heated to above its "annealing point" of 600 °C; its surfaces are then rapidly cooled while the inner portion of the glass remains hotter. The different cooling rates between the surface and the inside of the glass produces different physical properties, resulting in compressive stresses in the surface balanced by tensile stresses in the body of the glass. “Ref: Glass for Europe”
These counteracting stresses give toughened glass its increased mechanical resistance to breakage, and are also, when it does break, what cause it to produce regular, small, typically square fragments rather than long, dangerous shards that are far more likely to lead to injuries. Toughened glass also has an increased resistance to breakage as a result of stresses caused by different temperatures within a pane.
Laminated Glass –
is made of two or more layers of glass with one or more "interlayers" of polymeric material bonded between the glass layers. Laminated glass is produced using one of two methods:
Poly Vinyl Butyral (PVB) laminated glass is produced using heat and pressure to sandwich a thin layer of PVB between layers of glass. On occasion, other polymers such as Ethyl Vinyl Acetate (EVA) or Polyurethane (PU) are used. This is the most common method.
For special applications, Cast in Place (CIP) laminated glass is made by pouring a resin into the space between two sheets of glass that are held parallel and very close to each other.
Laminated glass offers many advantages. Safety and security are the best-known of these -- rather than shattering on impact, laminated glass is held together by the interlayer, reducing the safety hazard associated with shattered glass fragments, as well as, to some degree, the security risks associated with easy penetration. But the interlayer also provides a way to apply several other technologies and benefits, such as colouring, sound dampening, resistance to fire, ultraviolet filtering, and other technologies that can be embedded in or with the interlayer.Laminated glass is used extensively in building and housing products. Most building façades and most car windscreens, for example, are made with laminated glass, usually with other technologies also incorporated. “Ref: Glass for Europe”
Low-E Glass –
is achieved by coating glass during the manufacturing process. The purpose of this coating is to increase thermal efficiency by limiting the amount of heat that is transferred through the glass. By reflecting the heat back to its source, it keeps your home cooler in the summer and warmer in the winter. There are two types of Low-E coatings on glass: Soft coat and Hard coat.
Soft coat Low-E is achieved by subjecting a finished piece of glass to a chemical process which leaves a thin metallic coating on one side of the glass. This method produces thermally greater product than its hard coat counterpart, which is why it is the most common form of coating.
Hard Coat Low-E also known as “Pyrolytic”, hard coat Low-E is achieved by subjecting glass to a chemical process during its production. The resulting product is much more durable than soft coat, which is why it’s primarily used in single-glazed applications where the glass would be open to the environment.
To explain U-Value (click for description)
Thermal conductivity U measures the heat energy that will be transmitted through 1 m2 of material in one hour when there is a difference of 1 Kelvin across two surfaces of the material. The unit of measure of thermal conductivity is W/m2K.
The thermal conductivity of glass units depends on the type of glass used (customary glass, selective glass with different emission factors), the number of glass sheets in the glass unit, the width of air space and the type of the filler gas.
Uw (w = window) – overall value of the window
Ug (g = glazing) - U-value of the glazing
Ψg (linear heat transfer coefficient)
Uf (f = frame) – U-value of the frame
The heat transfer coefficient Uw relates to the entire window. This value also includes the U-values for the glazing and the frame Uf. The overall value Uw is also influenced by the linear heat transfer coefficient Ψg (g = glazing) and the size of the window.
U-value of window glazing: Ug
The Ug value is a function of the type of gas filling of the intermediate space between the glass sheets, the distance between the sheets and the number of sheets.
Typical U-values for thermally insulated windows are:
Double insulated glazing 24 mm with argon filling - 1.1 W/m2K
Triple insulated glazing 36 mm with argon filling - 0.7 W/m2K
Triple insulated glazing 44 mm with argon filling - 0.6 W/m2K
Triple insulated glazing 36 mm with krypton filling - 0.5 W/m2K
U-value of window frame: Uf
The Uf value for the frame-sash combination is defined by means of measurement or calculation. The area for the calculation of the Uw value is the cross-section of the profile.
Linear heat transfer coefficient Ψg
The value Ψg for the edge seal of the glazing is first and foremost a function of the used material for the insulated glazing spacer. The standard material with the worst thermal properties is Aluminium. Spacers with improved thermal insulation are referred to as “warm-edge” spacers. These spacers are made of stainless steel or plastic. A larger edge cover of the insulated glazing in the sash profile further enhances the Y-value of the edge seal.
Examples of Ψ-values:
Aluminium spacer: approx. 0.08 W/m2K
„Warm edge" spacer: approx. 0,04 W/m2K
U-value of window: Uw
The heat transfer coefficient for windows and window doors Uw is usually calculated in the standard window size 1230x1480mm
Window U-value worsens as the size decreases, larger windows feature better values. This is because U-values achieved in glazing are better than in the frame material and therefore a larger glass area is able to produce a better thermal insulation value.
The following formula is used to determine the heat transfer coefficient:
Ug = heat transfer coefficient of the glazing
Uf = heat transfer coefficient of the frame
Ψg = linear heat transfer coefficient of the insulated glazing edge seal
Ag = glass area
Af = frame area
Aw = Ag + Af
lg = length of inside edge of frame profile
Glazing bars, transoms and mullions can be added into the frame to form different glazed or sashed configurations. Individual designs can be created within the glazing areas by using a variety of 'add-on-bars'.
The sealing between the sash and frame is achieved by two or three continuous weather-strips. This is compressed by the sash onto the frame rebate thus ensuring maximum weather tightness when subjected to severe weather conditions.
