Roland Sini doors and windows the use is made of a partition material applied between double glazing, which aims to achieve the function of heat preservation and noise reduction. At present, hollow glass can choose a variety of glass to make hollow glass according to different needs, for example, hollow glass composed of laminated glass has better sound insulation effect; The hollow structure with three glasses and two cavities is more energy-saving. However, it determines the effect of each sound insulation and energy saving. Taking common specifications as an example, the 2cm warm edge spacing strip in the middle of the glass plays a vital role.
Roland Sini systematic door and window series adopts multi-cavity broken bridge aluminum structure, with special multi-layer sealing design, which makes water and gas divided into two independent chambers, thus improving the water of doors and windows to a certain extent, air tightness can greatly reduce the indoor and outdoor heat conduction caused by air convection.
On the basis of broken bridge aluminum design, Roland Sini chose 6063 high-strength original aluminum profiles high-speed rail EPDM strip to create a more durable and sealed high quality door and window system, meeting the strict performance standards of Europe.
