Description

The object of the invention is an insulating bead for window installation in building wall openings, used mostly as a bead installed under windows, adapted to installation of window sills, and an insulating window frame made of insulating beads, installed in the window opening and blocking flow of heat between the building wall and the window frame. This frame is useful from the point of view of window installation in traditional and framework constructions, in particular in energy-efficient and passive buildings.
Polish utility model disclosure No Ru 67895 provides a profile installed under windows, used in construction joinery applications. The transverse outline of the profile is approximately rectangular, wherein four closed side compartments, adjacent in pairs and with rectangular outlines are formed inside the profile, with said compartments being separated at the bottom by a rectangular compartment, and with an open-top central channel located above the rectangular compartment. One of the side compartments is filled with foamed polyethylene or polyurethane. Pairs of longitudinal, angled mounting ribs are formed on top and under the profile.
Protruding edges of top ribs of this profile are adapted to mesh with side edges of its bottom ribs, facing one another. Similar solutions of insulating glazing beads are known from utility model disclosures DE 299 24 754 U1 , DE 20 2008 015 551 U1 and DE 299 20 777 U1 , which disclose profiles with two, three and four circumferentially closed compartments. On the other hand, Polish patent disclosure PL 202876 discloses a known insulating frame of a roof window made of four individual, oblong insulating pads which form a quadrilateral set and are joined at the corners. Each pad is formed by an insulating profile made of a foamed plastic and a stiffening profile glued thereto. This frame known in the art adheres to the circumference of a window frame and is installed on rafters and roof structure battens using flange joints. Patent disclosure EP 2639394 A2 also discloses an insulating window frame, made of four oblong supporting-insulating pads attached to the circumference of a quadrilateral window frame and to the edges of the window opening made in a building wall. The supporting-insulating pads are stretched along the sides of this opening and attached to the front bearing surface of the wall layer. If a wall is installed in a frame made of such placed pads, the window frame protrudes out of the wall and beyond the edge of the opening made in the bearing layer of the wall. Only once the external insulating layer is applied on the frame, usually comprised of a styrofoam or a mineral wool layer, the frame and the window installed therein are located within the layer, practically
outside the bearing layer of the wall. The cross-section of the known supporting-insulating pad is approximately that of a triangle or a trapeze. An embodiment of this known solutions uses a pad made of two glued parts, wherein each of said parts has triangular cross-section. One part of the pad provides support and is made of thermoinsulating material with high mechanical resistance, whilst the other is made of foamed thermoinsulating material. Both variants of this known solution include an insulating frame tightly surrounded by the insulating coating of the wall.
The insulating bead for window installation in building wall openings according to the invention has an approximately rectangular outline of its cross-section, and it is at least partially filled with a foamed insulating material and it is provided with two opposite sets of protruding, longitudinal mounting ribs on its top and bottom surfaces. Protruding outside, attaching side projections of top ribs of the insulating bead are adapted to mesh with mounting ribs of the window frame and with attaching side projections of bottom ribs of a twin insulating bead, facing each other. The insulating bead according to the invention is characterised in that it has the shape of an open profile with a shape generally that of a U-profile, the interior of which is limited by side walls, top ribs and by the bottom and it is completely filled with foamed insulating material. In another, similar embodiment of the invention, the insulating bead also has an approximately rectangular outline of its cross-section, and it is at least partially filled with a foamed insulating material and it is provided with two opposite sets of protruding, longitudinal mounting ribs on its top and bottom surfaces. Protruding outside, attaching side projections of top ribs of the insulating bead are adapted to mesh with mounting ribs of the window frame and with attaching side projections of bottom ribs of a twin insulating bead, facing each other. In the case of this different embodiment of the invention the insulating bead is characterised in that it is formed as a closed, multi-compartment profile with an approximately rectangular outline, and at least one of its compartment is hollow. In both solutions of the insulating bead longitudinally placed, facing each other and concave ribs protrude from the top of the shelf, whilst the bottom of the insulating bead is provided with longitudinal and protruding downwards sealing ribs. Shelves of top ribs of the insulating bead and sealing ribs of its bottom have approximately triangular, matching outlines, providing tight connections of insulating beads, placed one on top of the other. Side walls of the insulating bead are provided with retaining grooves, in order to facilitate installation of additional elements, in particular of window sills. It is preferred, if retaining grooves are provided with T-shaped outlines.
According to the invention, the insulating frame of the window is made of oblong insulating pads, which are attached to the circumference of its polygonal frame and to the frames of the window opening provided in the building wall. According to the invention, the insulating frame is characterised in that each of the pads is made of at least one insulating bead, provided with mounting ribs on top and on the bottom surface, wherein the side attaching projections of the top mounting ribs of an insulating bead are meshed with mounting ribs of a window frame, and also match the outline of side attaching projections of the mounting ribs formed on the bottom of a twin insulating bead. The top and the side pads of an insulating frame are formed as single insulating beads. The top pad of the insulating frame is made of two twin insulating beads placed one on top of the other and press-fit meshed with each other using their mounting ribs. In another, improved embodiment of the invention, the insulating frame of a window is also made of oblong insulating pads, attached to the circumference of its polygonal frame and to the frame of the window opening. This improved insulating frame is characterised in that each pad is made of at least one insulating bead, provided with longitudinal mounting ribs on the top and on the bottom, wherein side attaching projections of mounting ribs of the insulation bead are meshed with mounting ribs of the window frame, and match the outline of side attaching projections of mounting ribs, formed on the bottom of a twin insulating bead. Sills and insulating panels adhere to individual pads, attached with their longitudinal edges to the side walls of the insulating beads. In order to immobilize the insulating beads, their bottom mounting ribs are embedded in a layer of foamed insulating material, filling the space between the frame of the window opening and the internal sill and internal insulating panels. In a preferred embodiment of the invention, sills adhere to both sides of the bottom pad of the insulating frame, whereas insulating beads adhere to both sides of the top pad and of the side pads. If the window has to be provided with an external roller blind, sills adhere to both sides of the bottom pad of the insulating frame, insulating beads adhere to both sides of side pads, and only the internal insulating panel adheres to one side of the top pad. A simplified solution is also used in this situation, in which sills adhere to both sides of the bottom pad of the insulating frame and only the internal insulating panels adhere to one side of the top pad and of the side pads. Longitudinal edges of sills and of insulating panels are provided with T-shaped protrusions, in order to enable insulating panels to be joined with insulating beads of pads of the insulating frame, which are meshed with longitudinal T-shaped retaining grooves provided in side walls of the insulating beads. The top and the side pads of an insulating frame are formed as single insulating beads. The bottom pad of the insulating frame is made of two insulating beads, placed one on top of the other and press-fit meshed with each other using their mounting ribs. A spacing bushing with a front-mounted flange is provided in order to reinforce the insulating frame between each of the internal, side insulating panels and the frame of the opening window, the terminal section of said bushing being retained in this insulating panel, and the flange adhering to the frame of the window opening. A bolt is placed inside the spacing bushing, which retains the insulating panel on the frame of the window opening. In another embodiment of the invention, each of the sides of the insulating frame is provided with an angled sheet of reinforcing mesh in order to reinforce the frame, wherein one part of the sheet is permanently attached to the surface of the internal insulating panel and the other part of the sheet adheres to a building wall on the inside.
Thanks to such solutions according to the invention the insulating bead, as well as the insulating frame of the window, formed using insulating beads, is characterised by high mechanical resistance and low thermal conductivity.

An insulating bead according to the invention, intended for installation of windows in building wall openings, according to Fig.1 and 2 has the form of an open-top profile 1 with an approximate U-shaped outline, made of rigid plastic. Two sets of opposite, protruding and longitudinally extending retaining ribs 2 and 3 are formed on the top and on the bottom of profile 1. The top part of profile 1 is provided with a pair of angled, top mounting ribs 2, which form an extension of the side walls 4 of the profile and which are provided with outwardly formed, side attaching projections 5. A pair of angled, bottom ribs 3 protrudes from the bottom of profile 1 with opposite side attaching projections 7. The top ribs 2 of profile 1 are adapted to press-fit meshing with T-shape mounting ribs 8 of the window frame 9. The distance D between projections 5 of top ribs 2 of profile 1 is slightly bigger than distance d of projections 7 of its bottom rims 3, which allows top ribs 2 of the first profile 1 to be meshed with bottom ribs 3 of the second profile 1' of two, or more twin insulating beads are placed one on top of another. The interior of profile 1, limited by its side walls 4, top ribs 2 and the bottom 6, is fully filled with insulation material 10 provided as a foamed plastic, in particular with polyurethane. Opposite, longitudinally formed and concave on top shelves 11 protrude from top ribs 2 of profile 1. On the other hand, the bottom 6 of profile 1 is provided with two longitudinal and downwardly protruding sealing ribs 12. Shelves 11 of top ribs 2 and sealing ribs 12 of the bottom 6 have matching, approximately triangular outlines. Side walls 4 of profile 1 are provided with longitudinal retaining grooves 13 with approximately T-shaped outlines on the outside. In a different embodiment of the invention according to Fig.1a the insulating bead comprises a closed, three-compartment profile 104' with an approximately rectangular outline, in which terminal compartments 104a, 104c are filled with a foamed insulating material 10, whilst the internal compartment 104b is hollow. Fig.3 presents a set of two profiles 1 and 1' placed one on top of the other and meshed together, wherein aperture 17formed between them, limited by shelves 11 and by sealing ribs 12 on the side, is filled with foamed insulation material. Insulating beads according to the invention may be used to form a quadrilateral insulating frame 19 of a window, which surrounds the window frame 9 on the outside and adheres to frames 20 of the window opening on the inside. Insulation frame 19 of a window is made of four oblong pads 102, which surround the window frame 9 on the outside and adhere to the circumference of frame 20 of opening window 119 in a wall 30 of the building. Pads 102 of top and bottom parts of the insulating frame 19 are made of single insulating beads 103 provided as open profiles 104. On the other hand, the bottom pad 102 of the insulating frame 19 presented in Fig.6 is made of twin insulating beads 103 and 103' provided as open profiles 104, placed one on top of the their and meshed with their mounting ribs 2 and 3. In the embodiment according to Fig. 10 and 11 pad 102 of the top part of the insulating frame is made of three identical beads 103 and 103' provided as open profiles 104, installed one on top of the other and press-fit meshed with their mounting ribs 2 and 3. This solution provides a thicker insulation frame, and the window frame 9 may be installed in a wider opening window 119, ensuring even lower thermal conductivity. This solution additionally provides the option of including a roller blind case therein, which is placed in the space occupied by top insulating edges 103', if necessary. T-shaped protrusions 14 of the internal and of the external sill 15, 16 are retained in grooves 13 of side walls 4 of profile 1' of the bottom pad 102. Both sills 15, 16 are additionally glued to side walls 4 of profile 1' in order to reinforce the joints. In order to provide a tight joint of two overlapping beads 103 and 103', their separating aperture 17, limited by sealing ribs 12 of the top bead 103 on the sides, is filled with a layer of foamed insulating material 10. In another, improved embodiment, the insulating frame 19 of a window is made of oblong insulating pads 102, which adhere to the circumference of the quadrilateral frame 9 and to frames 20 of the window opening 119 provided in the wall 30 of a building. According to Fig.16 pad 102 comprises an insulating bead 103 provided as an open profile 104. Its interior, limited by side walls 4 and by the bottom 6, has an approximately U-shaped outline and is completely filled with insulating material 10 provided as a foamed plastic, in particular as polyurethane. The pad 102 may also be provided as an insulating bead 103 according to Fig.1a in the form of a closed, three-compartment profile 104' with an approximately rectangular outline, in which terminal compartments 104a, 104c are filled with insulating material 10, and the middle compartment 104b is hollow. Longitudinal mounting ribs 2 and 3 are formed on the top and on the bottom of the insulating bead 103. External, side attaching protrusions 5 of top ribs 2 of bead 103 are meshed with mounting ribs 8 of the window frame 9, and they are matching the outline of internal, attaching side protrusions 7 of ribs 3, formed on the bottom of the twin insulating bead 103'. Sills 15, 16 and insulating panels 15a, 16a adhere to the sides of individual insulating pads, joined on their longitudinal sides 21 with side walls 4 of the insulating bead 103, 103'. Bottom mounting ribs 3 of the insulating bead 103, 103' are embedded in a layer 22 of foamed insulating material, which fills the space between frame 20 of the opening window 119 and the internal insulating panel 15a. In the embodiment according to Fig.12 and 13 internal sill 15 and external sill 16 adhere to both sides of the top pad, and internal insulating panels 15a and external insulating panels 16a adhere to the top pad 102 and to side pads 102 of the insulating frame. If an external roller blind not presented in the figure has to be installed in the top part of the window opening 119, then according to Fig. 14 internal sill 15 and external sill 16 adhere to both sides of the bottom pad 102, internal insulating panels 15a and external insulating panels 16a adhere to side pads 102, and only the internal insulating panel 15a adheres to one side of the top pad 102. In a simplified embodiment of the insulating bead, the internal sill 15 and the external sill 16 adhere to the bottom pad 102, and only internal insulating panels 15a adhere to one side of the top pad 102 and of side pads 102. Side walls 4 of the insulating bead 103, 103' are provided with longitudinal retaining grooves 13 with T-shaped outlines on the outside. Retaining grooves 13 mesh with T-shaped protrusions 14 on longitudinal edges 21 of sills 15, 16 and of insulating panels 15a, 16a. The top and the side pads 102 of the insulating frame 19 are formed as single insulating beads 103. According to the solution presented in Fig. 12 - 14 the bottom pad 102 of the insulating frame 19 is made of two insulating beads 103 and 103', placed one on top of the other and press-fit meshed mounting ribs 2 and 3. This solution provides an elevated insulation frame, and the window frame 9 may be installed in a tall window opening 119, ensuring even lower thermal conductivity. In order to achieve tight connection of two beads 103 and 103' adhering together each of the beds is provided on its bottom with two longitudinal sealing ribs 12 with a triangular outline. The top surface of each bead 103, 103' is additionally provided with a longitudinal groove 18 formed therein, filled with flexible sealing material when the insulating frame 19 is joined with the window frame 9. As it is shown in Fig.18 and 19, between each of the internal, side insulating panels 15a and the side frame 20 of window opening 119 a spacing bushing 23 with a front-mounted flange 24 is provided. The terminal section 25 of the bushing 23 is embedded in the insulating panel 15a, and the flange 24 of bushing 23 adheres to the frame 20. Bolt 26 is placed inside the bushing 23, which attaches panel 15a to the frame 20. Stable installation of the insulating frame 19 in the window opening 119 may also be achieved using the solution according to Fig.20 and 21, in which each of the sides of the insulating frame 19 is provided with an angled sheet 27 of reinforcing mesh. First part 28 of the sheet is permanently moulded into the surface of the internal insulating panel 15a, whilst the second part 29 of the sheet adheres on the inside to the building wall 30. When the window frame 9 is installed in the window opening 119 both parts 28, 29 of the sheet 27 of reinforcing mesh are coated with a layer of plaster not presented in the figure.
