Some time ago, Roland Sini explained the importance of wind pressure resistance, air tightness and water tightness for everyone. Today, we will continue the water tightness (Portal) of the previous issue to tell you why the system
the watertightness of doors and windows is stronger than that of ordinary doors and windows.
Watertightness is one of the important performances of doors and windows, and is the most important one in the performance index of doors and windows!
What is the watertightness of doors and windows
watertightness refers to the ability of closed doors and windows to prevent rainwater leakage under the simultaneous action of wind and rain. If the watertightness of the outer window is not good, when it comes to windy and rainy weather, rain will leak to the room through the window with the help of wind.
What is the watertightness level of doors and windows
the watertightness of doors and windows is divided into 6 levels. The higher the level, the stronger the waterproof performance. Doors and windows with good waterproof performance can effectively prevent rainwater from intruding into the internal structure of doors and windows, and the service life of doors and windows will be longer.
Why are system doors and windows watertight
roland Sini high-performance system doors and windows adopt the combination of system glue injection technology and internal drainage principle to ensure the watertightness of the whole window. Between the Casement and the window frame, the glass and the Casement are sealed with anti-aging and elastic sealant, and its material reaches the physical performance index GB1200289 stipulated by the national standard (sealing strip for plastic doors and windows). When Casement is closed, the adhesive strip can be pressed on the window frame well, reducing the possibility of rainwater penetration.
Roland Sini high-performance system doors and windows adopt multi-channel high-performance sealing design. A sealing strip is installed between the Casement inner and outer sides, the center and the inside, and the window frame to form a multi-channel seal. The outer seal blocks rainwater, the inner seal blocks outdoor gas, and the central seal forms a cavity, so as to effectively block rainwater into the room through the effect of outdoor wind pressure, and the interior wall of the window frame is heightened to block rainwater and improve the overall watertightness of doors and windows.
At the four corner joints of Casement, gaps will occur at the joints between muntin and window frames. If the machining accuracy is poor and the angle error is large, the gaps will be large and water will easily enter. Roland Sini adopts international advanced technology and European imported flexible production line automation, refinement, information operation, so that the joints are closely coordinated, the gap is extremely small, to prevent rainwater from penetrating through the gap.
At the same time, due to the high precision, the Assembly precision of profiles and accessories such as dagger, corner set, hinge, etc. is high, and the whole is tight, reducing the passage of rainwater infiltration from the outside to the inside.
Outdoor under the influence of wind often produces pressure on the indoor, and rainwater will permeate into the indoor along this pressure. The middle sealant strip is added to the center of the Casement and window frame of the high-performance system doors and windows of Roland Sini, which divides the cavity between the frame and the fan into two chambers, the outside is a watertight chamber, and the inside is an airtight chamber, an isobaric chamber is formed on the outside. The pressure in the isobaric chamber is equal to the outdoor pressure, preventing rainwater from entering the chamber. According to the siphon principle, rainwater flows out to the outside through its own gravity.
The watertightness of doors and windows is related to the strength of doors and windows bars, the section and material of adhesive strips, drainage system, window structure design, etc. Roland Sini doors and windows integrate system thinking to develop sustainable high-performance high-end doors and windows, meet the diversified individual needs of users, provide intelligent and practical space design and elegant and luxurious life experience, provide more families with the enjoyment of quality and taste.
