A splicing pipe for installing a door or window includes a first frame profile, a second frame profile, a heat insulation strip and at least two fasteners. A first clamping groove is formed on each of two sides of the first frame profile, and a second clamping groove is formed on each of two sides of the second frame profile. The first clamping groove and the second clamping groove are both configured to be connected to the door or window having glass. At least one of the first frame profile and the second frame profile on the same side is provided with an installation groove, and the fastener is inserted into the installation groove. The splicing pipe provided has the advantages of simple splicing operation and easy implementation, which can not only improve the splicing speed, but also guarantee the performance of the doors or windows after being spliced.

There is included an intermediate element including one or more, but not necessarily limited to, an L-shaped profiled portion configured to receive a part of a panel of a door or window, a pad configured to be fit into at least one frame part and comprising a support strip groove, and an intermediate element extended from the L-shaped portion to the pad.

A window frame system for fixing at least a first panel, includes at least a first window frame structure which includes at least a first window frame profile having at least first and second holders, and at least a first thermally insulating element with sixth and seventh holders. The second holder and the sixth and/or the seventh holder of the first thermally insulating element include at least one internal corner with a radius smaller than 0.5 mm. In this way, the dimensions of the window frame profile may be smaller than in the known window frame profiles. This may be advantageous for the total insulation value of the window frame system and the quantity of material required/used for the window frame profiles. Also disclosed is a thermally insulating element, a method, a window frame structure, a flexible profile, a control system and a sun protection system.

Methods and apparatus are disclosed for an adjustable door frame for an HVAC air handler. An example adjustable door frame for access to an HVAC air handler includes a hinge-side frame configured to couple to a hinge of a door for access to the HVAC air handler, a hingeless-side frame opposite the hinge-side frame, and one or more extensions configured to be positioned between the hinge-side frame and the hingeless-side frame to adjustably expand a depth of the door frame.

There is included an intermediate element including one or more, but not necessarily limited to, an L-shaped profiled portion configured to receive a part of a panel of a door or window, a pad configured to be fit into at least one frame part and comprising a support strip groove, and an intermediate element extended from the L-shaped portion to the pad.

There is provided a sash apparatus for securing in a window or a door, and a methods making same. The sash apparatus comprises a frame with multiple segments securable to the window or door, where each of the segments has an internal passage therein. The multiple segments are arranged and coupled together at non-straight angles to form the frame, with the internal passages within the segments in fluid communication with one another. The sash apparatus also includes a bonding fill at least partially filling the internal passages within the frame to hold the multiple segments together.

A thermally-broken slidable panel frame assembly formed from a plurality of aluminum profile assemblies. The aluminum profile assemblies can include different shaped aluminum profiles that can be coupled together with thermal break strips. The aluminum profile assemblies, in turn, can be snap fitted together to form a complete frame assembly that can support slidable panels. The frame assembly can be integrated with other components to form a slidable panel system for sliding doors or windows or other slidable panels. The frame assembly is assembled from multiple individual components, providing for ease in setup and installation compared to previous implementations.

The invention relates to a profiled plastic section (1) for a metal/plastic composite profiled section (31). The profiled plastic section (1) comprises a first profiled element (2) and at least one second profiled element (3). The first profiled element (2) and the second profiled element (3) together form a latching mechanism (4, 9; 5, 10; 6, 11), by means of which a form-fitting connection can preferably be produced between the first profiled element (2) and the second profiled element (3) in a width direction (x) and in a height direction (y). The first profiled element (2) and the second profiled element (3) overlap preferably over a large area when the form-fitting connection is produced between the first profiled element (2) and the second profiled element (3), and the form-fitting connection can be produced on the cross-sectional plane (x, y) between the first profiled element (2) and the second profiled element (3) by latching the profiled elements (2, 3) of the profiled plastic section (1). The form-fitting connection between the first profiled element (2) and the second profiled element (3) is designed such that a movement of the first profiled element (2) and the second profiled element (3) in a longitudinal direction (z) of the profiled plastic section (1) is allowed when a first metal component (29) is connected to the first profiled element (2) and a second metal component (30) is connected to the second profiled element (3) preferably in a shear-resistant manner. The profiled plastic section (1) can likewise also be designed with more than two profiled elements (2, 3), and the basic principle according to the invention of generating a shear-free plastic/metal composite profiled section (31) can be carried over.
