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.

The present invention describes a method for thermo-treatment of wood, where said method comprises the following steps: a) selecting the wood to be as free from knots as possible b) introducing the wood to a temperature increase up to approximately 173° C.; c) maintaining the wood at an ambient temperature of 173° C. for 3-5 hours; d) decreasing the temperature to approx. 20° C.; e) introducing the wood into an autoclave wherein a mixture of linseed oil and mineral oil is applied to the wood, and allowing the mixture to penetrate the wood f) retrieving and storing the treated wood. Furthermore a timber member made with wood treated according to the method is disclosed.

A window system according to an aspect of the invention includes: a window frame; an inner window installed at an indoor side of the window frame; an outer window fixed to the window frame and spaced apart from the inner window with a predetermined distance at an outdoor side to form a hollow layer between the outer window and the inner window; an air-flowing opening formed between the outer window and the window frame to form a flow path in which air in the hollow layer flows or circulates; and an opening and closing device provided at one side of the inner window to open and close the inner window from the window frame. The outer window may include a tinted glass or a glass having a high absorption rate and a bracket for fixing the tinted glass to the window frame.

A refrigerator is disclosed including a refrigerator compartment configured to store food, and a door configured to selectively open and close the refrigerator compartment. The door includes a first frame disposed on a front surface and side surfaces of the door, and second frames connected to a top and a bottom of the first frame, where the first frame and/or the second frames including fixing portions configured to fix the first frame to the second frames. A manufacturing method for efficiently manufacturing a refrigerator is also disclosed.

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.

A cover for closing an access opening that leads to an infrequently used space within a building, such as an attic, that generally provides an air seal, thermal insulation and/or acoustic insulation at the access opening. The cover may be in one or two portions, including a closure alone or a closure and a frame having an aperture that can be closed by engagement between the closure and the frame. When the cover is used alone it engages a frame or a wall circumscribing the access opening. The cover is sized and shaped to close a stairwell, or the opening at one end of a stairway, an opening in a generally vertical wall, a hatch, or a pull down ladder. The closure and frame are each made of one or more components.
