wooden doors and windows, etc.
I. Building aluminum alloy doors and windows
features of aluminum alloy doors and windows for buildings:
(1) the color is single, mainly including fluorocarbon Gray (used for balcony size sliding window) and electrophoresis Silver (there are many doors and windows);
(2) the frame type of the profile is single, and the fluorine carbon gray and electrophoresis silver are only different according to the region, and the style is not much;
(3) the profile structure is simple: the product is difficult to fit tightly;
(4) electrophoresis silver is used for single glass: suitable for southern market; Fluorocarbon Gray is used for double glass. If it is produced in workshop, the product quality is average;
(5) the quality of hardware accessories is average;
(6) poor thermal insulation.
II. Home aluminum alloy doors and windows
features of home aluminum alloy doors and windows:
(1) rich colors, including white maple, Golden Oak, electrophoresis champagne, Rosewood, Golden Oak, sand gray, brown, etc;
(2) strict structural design: elaborate design and self-development of hardware accessories. After many strict Assembly tests, in terms of color, style, width and finished accessories, to the market;
(3) affordable and widely used. The disadvantage is that the aluminum profile has the same color inside and outside, and the heat conduction is fast.

III. Bridge-cutoff aluminum alloy doors and windows
bridge-cutoff aluminum alloy doors and windows is an upgraded version for improving the thermal insulation performance of doors and windows on the basis of aluminum alloy doors and windows ". The principle is to divide the aluminum alloy profile into two parts inside and outside, and then use PA66 nylon material to connect the aluminum alloy profile to form a hot and cold bridge, so that the hot and cold energy inside and outside cannot be exchanged through the aluminum alloy profile, the internal and external colors can be matched arbitrarily, which is beautiful and has good performance. It is a new type of heat insulation aluminum profile. There is no heat insulation strip for aluminum alloy doors and windows, and the heat preservation and energy saving are far less than bridge-cutoff aluminum alloy doors and windows.
Bridge-cutoff aluminum alloy doors and windows features:
(1) reduce heat conduction. Adopting heat insulation broken bridge aluminum alloy profile, its heat-conduction coefficient is much lower than that of ordinary aluminum alloy profile; Adopting hollow glass structure, its heat-conduction coefficient is much lower than that of ordinary aluminum alloy profile, effectively reducing the heat conduction through doors and windows.
(2) prevent condensation. The temperature of the inner surface of the profile with heat insulation strip is close to the indoor temperature, which reduces the possibility that indoor moisture condenses on the profile surface due to saturation.
(3) Energy Saving: in winter, the window frame with heat insulation strip can reduce 1/3 of the lost heat through the window frame; In summer, if there is air conditioning, window frames with heat insulation strips can reduce energy loss and protect the environment more; Through the application of heat insulation system, energy consumption can be reduced, and environmental radiation caused by air conditioning and heating can be reduced at the same time.
(4) comfort and health: the heat exchange between human body and environment depends on indoor air temperature, air flow speed and outdoor air temperature. By adjusting the indoor temperature of doors and windows, it is not lower than 12 ~ 13℃ to achieve a comfortable environment.
(5) noise reduction: the hollow glass structure with different thickness and the cavity structure of heat insulation broken bridge aluminum profile can effectively reduce the resonance effect of sound waves, prevent the transmission of sound and reduce noise.
(6) colorful colors: Hundreds of aluminum profiles of different colors can be produced after surface treatment with anodic oxidation and powder spraying. After rolling combination, insulated aluminum doors and windows can produce indoor, two-tone windows of different colors outside.
Broken bridge aluminum doors and windows there are many advantages, but the disadvantage is that it is more complicated to make, and its hardware accessories are more expensive, which indirectly leads to higher cost.
IV. Aluminum-wood composite doors and windows
aluminum-wood composite doors and windows are made of wood on the outer layer and aluminum alloy on the inside, which is a new category of doors and windows combining aluminum and wood. It also reflects the "wood" culture in door and window products. Its characteristics:
(1) measures to resist temperature and humidity changes: changes in temperature and humidity will cause shrinkage of rod parts, etc. Aluminum-wood composite doors and windows are between aluminum and wood, there is a certain gap between the frame and the fan, which can eliminate the influence caused by deformation, thus avoiding quality problems caused by temperature resistance and humidity change;
(2) insulation and sound insulation performance: Glass generally adopts 5mm 12A 5mm hollow glass, the wood is specially degreased and dried, and the moisture content of the wood is strictly controlled within the required range, and cut the wood into short materials first, which are integrated by teeth, and are not easy to deform. Aluminum and wood are connected through special connectors, with a certain distance left in the middle, and the hollow gap of hollow glass reaches 12mm, after the whole window is installed, the indoor and outdoor air cannot communicate, thus making the heat preservation and sound insulation performance reach the ideal effect;
3) material: the hardware adopts high quality hardware, and the paint does not contain heavy metals. It has good waterproof and breathable effects, and has good adsorption force, no falling off and no discoloration. Profiles are produced by well-known domestic brands, and sealant strips are produced by better EPDM strip at present, which reduces the disadvantages of easy deformation and aging, etc;
(4) waterproof, moisture-proof and other properties: special glass mats are used to pad and connect the hollow glass to the frame body, which plays a certain shock absorption role. Special isolation adhesive strips are used to isolate the outside of the overlapping room between the fan and frame, prevent rainwater from penetrating into the room directly;
(5) the interior side of aluminum-wood composite doors and windows is mostly solid wood, which improves the grade of buildings and also reflects good visual effects.
Disadvantages of aluminum-wood composite doors and windows: the majority of profiles are solid wood, and the main stress materials and solid wood of doors and windows are scarce, and the cost is expensive; The manufacturing process of profiles and doors and windows are various and complicated, and the equipment is expensive, the threshold is high, it is difficult to reduce the comprehensive cost.
