Description

Technical Field

[0001] This utility model relates to the field of energy-saving doors and windows technology, specifically to a building PVC energy-saving door and window. Background Technology

[0002] Plastic steel windows are still widely used after wood, iron, and aluminum alloy windows due to their lower price and better performance. The window frame is made of polyvinyl chloride resin as the main raw material, with a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., and is extruded into a profile.

[0003] The utility model with announcement number CN214576545U discloses an energy-saving thermal insulation PVC window and door, which includes a PVC frame, a glass strip set in the PVC frame, and thermal insulation glass located between the PVC frame and the glass strip. The PVC frame has an installation groove for placing the thermal insulation glass on the side near the glass strip. The PVC frame has multiple movable grooves along its thickness on the side away from the glass strip on the side of the installation groove. One end of the movable groove is connected to the installation groove, and the other end of the movable groove is closed. Multiple movable blocks are fixedly connected to the side of the thermal insulation glass away from the glass strip. The multiple movable blocks slide in the multiple movable grooves respectively. A locking element is provided between the PVC frame and the movable blocks to limit the sliding of the movable blocks.

[0004] The above technical solutions reduce the swaying of insulated glass, improve the sealing and insulation performance of PVC windows and doors, and help extend the service life of PVC windows and doors; however, the large gaps between PVC window slats can easily cause air leakage, which reduces the indoor insulation performance. Low insulation performance leads to high energy consumption for indoor insulation, and PVC window slats are not easy to disassemble and replace quickly after damage, which cannot reduce the impact of material replacement on the overall structure.
