The continuous innovation of architecture has allowed people to quietly change their lifestyles while enjoying the fruits of architecture.

However, it is not an easy task to create a new experience of comfortable and warm living, and truly achieve the goals of noise reduction, sound insulation, energy saving and heat preservation. System upvc doors and windows with truly energy-saving effects have strict quality requirements in terms of material, sealing, and structure.

The ultra-low energy system upvc doors and windows with excellent system performance are sturdy, safe and recyclable, with a modern minimalist aesthetic appearance. Crown clearly understands the needs of architects, developers, contractors, manufacturers and individual users, so as to design innovative, technologically advanced and highly flexible product portfolios.

Hollow glass, heat insulation

Crown chooses double-layer or triple-layer tempered insulating glass, which can perfectly form a fully enclosed hollow layer with a noise reduction of 35-42dB. In addition, the integrated bending technology of aluminum spacers makes the insulating glass "seamless and leaky" ", to ensure the sound insulation of upvc doors and windows and energy saving and heat preservation.

The EPDM material sealing strip used by Crown is different from the common rubber sealing strips on the market, and has stronger high temperature resistance, low temperature resistance and corrosion resistance. At the same time, the corners of doors and windows are designed with integrated vulcanization and corner forming technology, which has better sealing and sound insulation performance.

Innovative structure, thermal insulation

The polymer composite profile, multi-chamber structure design, layer-by-layer sealing, and strong thermal insulation performance ensure that Crown doors and windows can reduce the loss of indoor air-conditioning and heating, and achieve the effect of "five-constant" comfortable space.
