WHAT DO WINDOWS CONSIST OF?
The main parts of a window are a frame, a sash, fittings and a glass structure:
Frame – the immovable part of a window that holds the window sash.
Sash – the movable part of a window.
Glass structure – a transparent structure consisting of two or more consisting of two or more hermetically interconnected glasses. Depending on how many glass sheets are used, glass structures are divided into two types – a single-chamber window structure, which consists of two glasses and one chamber, and double-chamber window structure, which consists of three glasses and two chambers.
Fittings – handles, locking mechanisms and devices for opening, fixation and closing the window.
Armour profile – a steel element inside the profile that ensures the stability of the structure.
Window structures are made from a standard set of profiles. The most commonly used are two profiles. Frame profile – used for making a basic structure (frame). Sashes – sashes and other opening elements. Impost or crossbar serves as a frame divider in contours that can include a sash or sash hanger in three or more sash windows.
Glazing bead – the construction that serves to stabilize the glass structure.
Outer sill – the lower outer part of the window sill that protects the frame from entering the water.
Sill – the lower inner part of the frame, which protects the building from the entrance of the cold and the loss of heat, and regulates the heat and cold flow.
Window reveal – a plasterboard used for finishing the side zones.
Windows, as a construction product of building envelopes, are the weakest elements of the building from the point of view of thermal insulation. If the windows made of PVC profile systems are used, it is important that they comply with the requirements for the Regulations Regarding Latvian Construction Standard LBN 007-10 LBN 007-10 for the non-use of lead compounds in PVC compositions.
Particular attention should be paid to ensuring that the windows are properly installed and fixed in the window reveals, as well as that the window assembly joints are installed technologically correctly and according to appropriate sizes. It is also necessary to provide that the laying of the heat insulation material is performed correctly, insulation vapour barrier is used properly and the waterproofing barrier is made from the inside and the outside.
Equally important is the high quality finish of window reveals and the installation of window sills from the inside and outside, leaving no empty space under the rigips layer of window reveals and sills.
Every detail is important during the window installation process, so if you want to get high quality windows, do not try to save money at their expense.
The window structures of three glasses become increasingly popular. It is important to pay attention to the distance between the glasses and the profile system. From the point of view of thermal insulation, for 70mm thick profile systems it is inappropriate to use the structure of three glasses with a distance of 10-12mm between the glasses, because the benefits do not always correspond to the product price. It would be more rational to use the structure of three glasses for 88mm thick profile systems.
The main advantages of timber windows are naturalness and aestheticism, they fit into every interior. Nowadays, timber windows are different from the Soviet windows. Thanks to the developed technologies, they are much better in quality with the sealing materials incorporated in the frame concerning protection against rain and provision of ventilation. Timber windows are made of the preparation of glued pine timber in three layers, incorporating in them glass structures that can be of different thickness. The surface of timber windows can be stained, varnished or painted.
Timber aluminium windows
Timber aluminium windows are essentially timber windows with aluminium clad. Such windows have a much longer service life. Timber aluminium windows can be used in the places where the window is exposed to direct rainfall, balconies, loggias, winter gardens, etc. There are different variations of timber aluminium windows, for example, timber windows with aluminium clad on the outside, but the inside is made of timber, or vice versa.
