best aluminum fixed windows

⒉The color matching of doors and aluminium fixed window(including the color of glass and profile)
The color selection of doors and windows is an important part that affects the final effect of the building. The color of doors and aluminium fixed window must be matched with the characteristics of the building. When determining the color, it must be negotiated with architects, owners and other parties.
⒊Personalized design of doors and best aluminum windows
According to customers' different hobbies and aesthetic viewpoints, unique door and window facade shapes can be designed.
⒋Permeability of doors and windows
The elevation of doors and windows is within the sight height range of the main viewing part (about 1.5m～1.8m). It is best not to install horizontal and vertical frames to avoid obstructing the sight. Some doors and windows need to use glass with high light transmittance or require a larger open field of view to facilitate viewing of outdoor scenery.
⒌Lighting and ventilation of doors and windows
The ventilation area of doors and windows and the number of movable fans should meet the requirements of building ventilation; at the same time, the lighting area of doors and windows should also meet the requirements of the "Architectural Lighting Design Standard" (GB/T50033-2001) and the requirements of architectural design drawings. Article 4.2.4 of the "Design Standard for Energy Efficiency of Public Buildings" (GB 50189-2005) stipulates that the ratio of the window-to-wall area of each direction of the external windows of the building shall not be greater than 0.70. When the window-to-wall area ratio is less than 0.40, the visible light transmittance of the glass should not be less than 0.4.
Door and window safety design
⒈Wall thickness requirements of aluminum profiles for doors and windows
Classical style aluminum doors and best aluminum windows
Classical style aluminum doors and windows
The wall thickness of the window aluminum profile conforms to the current national standard high-precision level, and the minimum wall thickness of the stressed member is ≥1.4mm.
⒈The force-bearing members of doors and windows (such as light hooks of sliding windows, center pillars, bright sliding, bright up sliding, bilateral fronts, etc.) must undergo strict compression calculations. When the profile is used as a stressed member, its profile wall The thickness should be selected by calculation according to the conditions of use. The force-bearing members of aluminum alloy doors and windows shall be determined by tests or calculations.
⒉Safety design of door and window glass
⑴The choice of glass: the thickness of the glass is determined by calculation and should not be less than 5mm. Safety glass (tempered glass or laminated glass) must be used for doors and windows in the following parts of the building:
(A) Open windows outside buildings with 7 floors and above;
(B) Window glass with an area greater than 1.5 square meters;
(C) Floor-to-ceiling windows with the bottom edge of the glass less than 500mm from the final decoration surface;
(D) Inclined windows with an inclined roof with an angle of less than 75° to the horizontal and a distance of more than 3m from the indoor ground;
(E) Framed glass doors with glass area greater than 0.5 square meters;
(F) Frameless glass doors should adopt toughened glass with a thickness of not less than 10mm.
⑵The amount of overlap between the glass and the notch and other matching dimensions should meet the requirements of Table 5 and Table 6 in "Aluminum Alloy Window" (GB/T8479).
⑶ The glass and aluminum alloy frame groove should be in flexible contact with rubber gaskets.
⑷The glass should be mechanically edged, and the mesh number of the grinding wheel should be above 180 mesh.
⒊The choice and design of hardware accessories.
⑴ When choosing hardware accessories, try to choose products with guaranteed quality. The quality level of hardware accessories should be consistent with the quality level of doors and windows. The structure and shape of hardware accessories should match the profile, the colors are coordinated and beautiful, the function is correct, and the operation is flexible. , Easy to install.
⑵The installation of hardware accessories should be complete, standardized, reliable, and accurate. After installation, the doors and windows have beautiful appearance, flexible and convenient opening, without deformation, obstruction and collision.
⑶The exposed fasteners of hardware accessories should be made of stainless steel.
⑷Multi-lock points should be used when closing side-hung doors and best aluminum windows and large sliding doors and aluminium fixed window, otherwise the air-tightness will be greatly reduced under the action of negative pressure. Considering the convenience of operation, it is best to use multi-lock point handles or actuators.
⑸The length of the sliding support of the casement window is generally 2/3 of the width of the sash, if the sash is lighter, it can be 1/2, and the length of the sliding support of the upper-hung window is generally 1/2 of the sash.
⑹When opening windows outside typhoon areas and high-rise buildings, it is recommended that window sashes be installed with sliding braces instead of hinges.
