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.

Improved sliding window or sliding door with a leaf with a leaf frame that is composed of leaf profiles which each comprise two half-shells which are thermally connected to each other by an intermediate thermal insulator, whereby in the leaf frame a rebate is provided for a panel which is supported by one or more glazing bead supports in the rebate and whereby the leaf frame is supported by one or more roller cassettes with rollers, wherein at least one glazing bead support comprises a feed-through section for transmitting the weight of the panel or a part thereof to at least one concerned roller cassette and that this feed-through section extends through a bottom leaf profile of the leaf frame up to a roller cassette.

The present application relates to an arrangement for reducing thermal energy loss through a sill assembly of the type used with a door or window. The sill assembly includes at least one sill member. The at least one sill member has a hollow region therein. The sill assembly further includes a baffle disposed within the at least one sill member. The baffle spans a length of the at least one sill member and divides the at least one sill member into a plurality of chambers thereby limiting interaction of warmer air and cooler air within the at least one sill member. The baffle reduces heat transfer through the hollow region via convection.

Example aspects of a shear plate for a window frame assembly, a window frame assembly, and a method for insulating a window frame assembly are disclosed. The shear plate for a window frame assembly can comprise a shear plate body defining an outer shear plate surface and an inner shear plate surface, the shear plate body defining a first end, a second end opposite the first end, and a pair of lateral sides extending between the first end and the second end; and at least one pair of shear plate holes extending from the outer shear plate surface to the inner shear plate surface, the pair of shear plate holes oriented such that a line running through a center of the pair of shear plate holes is substantially parallel to the first end and the second end.

A profile for window, door, facade or cladding elements is disclosed, which comprises a profile body (2) made from thermoplastic material and extending in a longitudinal direction (z) with an essentially constant cross-section (x-y) along the longitudinal direction (z) and having at least one outer surface (2a), and a inorganic containing layer (4) deposited on at least part of the at least one outer surface (2a), wherein the thermoplastic material comprises at least one thermoplastic selected from the group containing polyamide, polyethylene, polybutylene terephthalate, acrylonitrile styrene acrylate, wherein the inorganic containing layer (4) is deposited directly on the profile body (2) using a cold spray technology, and wherein the inorganic containing layer (4) has a thickness in the range from 30 μm to 450 μm.
