Pattern description

The subject of the utility model is a window with special insulation and strength values, intended for use in residential houses and public utility buildings.

The current state of the art

It is known from Patent No. Pat. 178414 a window or other frame structure with a frame and a sash made of wooden profile (1) covered with a plastic shuttering profile (2) in such a way as to ensure ventilation and drainage of water from the "cold zone" windows and prevent damage to the wood caused by moisture penetrating between the profiles. The surfaces of the wooden profiles (1) mating with the shuttering profiles (2) are inclined. Wooden profiles (1) and plastic profiles (2) each have the same cross-sections.

It is also known from Pat. 201455 an openable window with cover elements of the window frame and sash, where in the roof window with the frame structure and the openable pane supporting structure, the window sash, the upper, lower and side elements (1-8) of the frame and the sash are mostly constructed as profiles wooden, which on their outer sides are covered with cover elements of weather-resistant material, connected to the wooden profiles by hooking and fastening means. The cover elements (11, 12, 15, 17, 20, 21, 32) include the upper and lower cap elements (20, 21) on the side elements (3, 4, 7, 8) constructed as flat profiles in the shape of a tray, the same cross section of a substantially U-shaped profile having an outer wall (20a, 21a) and two lower side walls (20b-c, 21b-c). At its upper end, the lower cap element (21) has a shoulder connection element (22) slid under the lower end of the upper cap element (20), the connecting element having such a shape that the cap elements (20, 21) in the closed position of the window are arranged with their outer walls (20a, 21a) and side walls (20b-c, 21b-c) in alignment with each other, the lower hood element (21), when the window is open, free to deviate outwardly with respect to the upper hood element (twenty).

It is also known from US Pat. 205293 roof window, where in the roof window with the openable window frame structure constituting the supporting structure of the window sash glass, the upper, lower and side elements (1 - 8) of the frame and the sash are mostly made of wooden profiles, which on their outer sides are covered with cover elements of weather-resistant material, connected to the wooden profiles by engaging and fastening means. The cover elements (11, 12, 15, 17, 20, 21, 32) serve as a tight cover for the underlying wooden profiles in the frame and sash structures on all surfaces outside the roof covering, and the latching and fastening means are designed in this way and / or positioned in relation to the sheathing elements such that it essentially prevents the penetration of moisture and water into the wooden profiles.

It is known from the utility model application W. 109827 a wooden window, made especially during the thermal renovation of windows in residential and industrial buildings. A wooden window has a built-in, profile cover strip (6) on the entire perimeter of the outer window frame (1), the fixing arm (7) of which is attached to the window frame (1) on a liquid nail, and the sealing arm (8) adheres to the sash with its end (2) and pressed against it.

It is also known from the utility model Wu. 66073 a window with external cladding, including a frame and sash, the frames (110, 120) of which are made of plastic and have a vertical plane (114, 124) on the outside and an inclined plane (115, 125) covered with claddings (130, 140) made of aluminum, with each cladding (130, 140) having along the edge shaped tabs (131, 132, 141, 142), with which it is attached to the edge (116, 126) of the vertical plane and the edge (117, 127) the oblique plane of the covered frame (110, 120), and moreover, it is glued on the inside (133, 143) to the oblique plane (115, 125) of the covered frame (110, 120) with a layer of glue (151, 152) continuously spread along the edge ( 117, 127) of the oblique plane and adjacent to the edge (117, 127) of the oblique plane.

A study of the state of the art shows that, until now, the purpose of using any type of cladding on jambs or window frames has been to protect the material of the jamb or frame from external weather conditions. This is done by covering the frame directly or through ventilation or moisture removal systems.

The purpose of the utility model is to reduce the heat transfer coefficients of the joinery, which is an expression of global trends. The concept of thermally insulated aluminum claddings is a solution that allows to obtain previously unattainable thermal insulation parameters of window joinery. Surprisingly, it turned out that the insulated aluminum cladding improved the thermal insulation compared to the windows of the order of 0.12 - 0.20 W / m2K, considered the best on the market in this respect.

These requirements are met by a utility model window.

The essence of a utility model

The essence of a utility model is that a window that opens inwards or outwards, built of a structural part, which consists of a frame and a sash with a frame structure, is characterized by the fact that the structural part is made of glued laminated timber and connected on the outside it is by means of appropriately arranged clips with a thermally insulated aluminum cladding covered with a high-strength powder paint coating. Moreover, the window is equipped with a triple glazing unit with an increased heat transfer coefficient, glued with special butyl masses, and the inter-pane spaces filled with argon. Moreover, the structure of the window enables the sash to be sealed with a special system of seals.

Preferably, the structural part, i.e. the frame and sash, are made of glued laminated timber with the use of composite inserts.

Preferably, the thermal insulator of the aluminum cladding is made of high quality PUR foam.

Preferably, the glazing unit has a heat transfer coefficient below 0.6 W / m2K.

Advantages of the utility model The main advantage of the utility model window are its thermal insulation parameters, which amount to approximately 0.78 - 0.80 W / m2K and are unique for the structures found and used on the market of windows. For comparison - the value of heat transfer Uw for a wooden window with improved thermal insulation parameters recognized on the market is about 0.9 - 1.0 W / m2K. The level of thermal insulation of windows according to the utility model allows them to be installed in Passive House buildings, for which external carpentry is required with the Uw heat transfer coefficient at a level not higher than 0.8 W / m2K.

An additional advantage of the window according to the utility model is glass glued to the wooden frame with special butyl masses. This innovative technology, borrowed from the automotive industry, allows for a significant improvement in the stiffness of the product while reducing the dimensions of the wing cross-section. This allows for a significant improvement in the ecological values of these products, because for the production of a window with reference dimensions of 1230 x 1480 mm, the demand for wood will decrease by approximately 14.0%.

Explanation of the figures of the drawing

The object of the utility model is shown in the drawing, in which Fig. 1 is a front view of the window with section A-A marked, Fig. 2 shows the vertical section A-A.

Execution example

The utility model window is a new generation product with a composite structure and consists of a wooden structural part, which consists of a frame 1 and a sash 2 with a frame structure, whose task is to transfer static and mechanical loads, and on the outside it is connected by appropriately spaced 5 clips with thermally insulated aluminum cladding 4 covered with a high-strength powder paint coating. The window is a modern concept of combining two materials - wood (1) and (2) with an insulated aluminum cladding (4) through appropriately placed clips (5) made of high-impact PVC and EPDM gaskets (6).

The window is equipped with a triple packet of 3 insulating glass units with a heat transfer coefficient below 0.6 W / m2K.

An extremely important modification in relation to standard windows is the introduction of the operation of sticking the glass to the wooden frame with the use of special butyl masses in this product, and the inter-pane spaces are filled with argon.

The structure of the window allows the sash to be sealed with a special system of seals.
