It is needless to say that you should like the style of doors and windows. You should also consider the quality of aluminum alloy profiles, sliding door hardware and accessories, door and window paint, tempered glass, pulleys and rails.
1) Frame profile of sliding door
The common aluminum alloy raw materials in the market include recycled aluminum, aluminum magnesium alloy, titanium magnesium aluminum alloy. On the one hand, the service life of doors and windows is determined by the frame structure, but the most important thing is the quality of aluminum.
Low quality recycled aluminum not only has a short service life, but also affects the performance of thermal insulation and sound insulation.
High quality aluminum alloy, or bridge breaking aluminum alloy, is generally high-quality raw aluminum, and PA66 insulation strip is used in the middle, which has good compression resistance, heat insulation and corrosion resistance.
When selecting, in addition to identifying the production brand of aluminum materials, you can also observe whether the surface and cross-section of aluminum materials are flat and whether there are burrs and bumps.
2) Hardware and accessories
Hardware includes upper and lower pulleys, handles, buffers, etc., and accessories include sealing strips, edge wrapping materials, etc.
Pulley is very important. The handle depends on the usage habits. It can be installed or not. However, it should be noted that different types of sliding doors should be equipped with different handles. When purchasing, you can pay attention to the brand of the handle.
The buffer can effectively solve the problem that the impact force is too large when the doors and windows are closed, resulting in door rebound and even door frame damage. The buffer with good quality can feel very smooth and even damping when opening and closing the door.
As for the quality of sealing strips and edge wrapping materials, it determines the effect of sound insulation and the durability of the effect. Verify the sound insulation effect of the sliding door and go to the store to experience it.
3) Paint finish of door frame
Quality manufacturers need to remove dust and impurities on the surface before spraying paint, spray with automobile grade metal powder, and then bake at high temperature to ensure that the surface has strong adhesion and does not fall off.
This is a detail that can easily be ignored. After all, the samples placed in the exhibition hall have not been exposed to the sun for a long time.
4) Tempered glass
The quality of glass also varies from manufacturer to manufacturer. Regular manufacturer, basically using tempered glass
Ordinary glass will break into many sharp small pieces after being damaged by force, while tempered glass will still be connected together in granular form after breaking.
There are also many types of glass, which can be selected according to your preferences. The popular ones are transparent and frosted glass, and the personalized ones are gray, Tan glass, and Changhong glass. Specific differences will be described in another article later.
As for the choice of glass color, as well as single-layer and double-layer insulating glass, it needs to be determined according to different places. For example, the bathroom door and kitchen door can be frosted, and other spaces can be determined according to different decoration styles. For single and double-layer glass, consider whether sound insulation is required.
In addition to the glass quality, the use experience of sliding doors should also check the tightness of the glass interlayer, whether the outer glass and the sealing strip are flat, and whether there is degumming and crimping.
5) Pulley mass
As the key part of the sliding door, the pulley directly affects the use experience of the sliding door.
Commonly used pulleys are divided into plastic pulleys, metal pulleys and glass fiber pulleys according to materials. The quality of the pulley is mainly determined by two parts: the material of the pulley and the internal bearing of the pulley.
Naturally, plastic pulleys are not recommended. It is recommended to go to the experience store to listen to whether there is noise during opening and closing. Push and pull to feel whether there is smooth and uniform damping and vibration frequency.
6) Sliding door track
The track of the lifting rail sliding door is located above, and the quality of the track can be mainly considered.
The selection of ground rail sliding door mainly considers indoor and outdoor, whether to use embedded or convex. For example, the sliding door of the balcony should use high and low rails to facilitate drainage. The built-in type can be used indoors for fear of hitting the ground rail when walking. However, the height of the ground rail of some sliding doors can be only about 1cm.
The simplest way to identify the stability of sliding door is to shake the sliding door and judge according to the shaking degree.
Maintenance
No matter how good the quality of doors and windows is, if they are not properly maintained, their service life will be shortened. How to do it?
When cleaning, clean water or neutral detergent shall be used. Never use corrosive liquid such as soap, washing powder and toilet detergent, which will directly corrode the adhesive strip and glass joint and affect its sealing property.
Pay attention to regularly cleaning the groove of the ground rail to prevent dust and sand from damaging the hardware and pulley.
Regularly check the hardware status of the sliding door to see if it is damaged, if the bolts are loose, if the sealing strip and glue fall off, and add lubricating oil.
If there is rust on the surface, pay attention to rust removal and waxing to prevent the spread of rust spots.
