This utility model relates to the field of doors and windows, specifically to an energy-saving window frame and window system for curtain walls. The energy-saving window frame includes a sub-frame profile made of glass fiber reinforced composite material. A first end of the sub-frame profile is fixedly connected to a steel keel by a first screw. A second end of the sub-frame profile has an installation chamber containing a liner. A second screw passes through the liner and is fixedly connected to a pressure block. This utility model, by using a sub-frame profile made of glass fiber reinforced composite material, extends the heat transfer path, significantly reduces the thermal bridging effect, and thus achieves the goal of reducing the heat transfer coefficient. It is energy-saving and environmentally friendly, possessing good economic efficiency and practicality. The liner in the installation chamber effectively increases the screw holding force and enhances connection stability.

The utility model discloses a kind of push-pull windows with heat insulation function, it is related to push-pull window technical field, including fixed window frame and heat insulation component, the fixed window frame is integrated structure, and the inside surface slidingly connected with sash window frame in fixed window frame, the heat insulation component is set to sash window frame surface, and heat insulation component includes first fixed groove, second fixed groove, nylon sealing gasket, polyurethane filler, hollow glass, nano ceramic heat insulation film, Low-E coated glass and scratch-proof film, the first fixed groove is opened in the inside surface inner end of sash window frame, and the second fixed groove is opened in the inside surface outer end of sash window frame. The push-pull window with heat insulation function, by heat insulation component, so that the device can greatly enhance the heat insulation performance of push-pull window whole, can significantly reduce indoor and outdoor heat exchange, reduce air conditioning or heating energy consumption, save electricity expense, by movable assembly, so that the device can reduce the friction of slide rail, reduce slide rail abrasion, to prolong its service time.

The utility model discloses a glass film with low hemispherical radiance and glass, the film comprises a release film layer (00), a pressure-sensitive adhesive layer (10), a resin film layer (20) and a magnetic control metal layer, the magnetic control metal layer is located on the upper surface of the resin film layer (20), and the magnetic control metal layer is of a multi-layer structure and comprises 1-4 metal reflecting layers (30) and an outermost low-radiation anti-oxidation layer (40). The low-radiation anti-oxidation layer (40) can protect the surface of the glass film from being scratched in the transportation and construction process, meanwhile, the low-radiation anti-oxidation layer (40) has the low radiation rate, and when the indoor temperature is high, radiation is mainly transmitted from the interior of a room, and the low-radiation anti-oxidation layer (40) can reflect heat back to the interior of the room.

The utility model provides a kind of pasted glass energy-saving reconstruction window, comprising: existing glass window, including fixed frame, opening window sash and existing glass, the existing glass is set on the fixed frame or opening window sash;Flexible warm edge strip, continuous adhesion in the whole perimeter edge of indoor side of the existing glass;Pasted glass, located indoor side of existing glass, be located on the flexible warm edge strip, and parallel with existing glass, pasted glass and the existing glass form sealed heat-insulating gas layer;Silicone structural adhesive, filled in the U-shaped embedded joint enclosed by the fixed frame or opening window sash, existing glass, pasted glass and flexible warm edge strip.The utility model provides a kind of pasted glass energy-saving reconstruction window, through the innovative design of double-glazing structure, significantly solve the deficiency of existing single glazing in heat insulation, sound insulation, safety, lighting and so on, it is a kind of simple, economic, efficient energy-saving reconstruction scheme.
