broken bridge aluminum series, the bigger the better?

At present, the mainstream broken bridge aluminum product series on the market are: 60, 70, 80, 90, 108, 130, etc. This type of model refers to the width of the profile (65mm,65mm,70mm and so on). The increase in the number of series does not represent the improvement of performance, but only represents the widening of the profile or the increase in function.


Safety of Glass

Generally, single-layer glass, laminated glass, vacuum glass and insulating glass are commonly used for door and window glass. laminated glass: is composed of two or more pieces of glass, sandwiched between one or more layers of organic polymer intermediate film, after high temperature and high pressure process after permanent bonding into one composite glass products, broken will adhere to the PVB film, glass slag will not fall.

hollow glass with three glasses and two cavities: hollow glass has the greatest function of heat insulation. The three glasses and two cavities are equivalent to the upgraded version of hollow glass. For homes with long-term air conditioning in summer, it is more cost-effective to add three glasses and two cavities.

The use of door and window glass should be within the load-bearing range of the frame. The thickness of tempered glass is usually above 5, which is more compressive and impact resistant to ensure the safety of doors and windows. If you need a large area of glass panoramic doors and windows, you can use laminated glass, laminated glass impact resistance is about 5 times stronger than tempered glass.


Height of Door and Window Handles

The windows in the home are not tailor-made for one person. Some door and window designs lack details. They do not pay attention to the height of the window sill and the user's situation. The handle is designed in the center directly. After installation, it will be found very inconvenient to open and close the windows. Handle height is only a small detail of the practicality of doors and windows, but should also fully consider the height of the window sill, the height of the window operator, and the direction of the window operator.

So the principle of determining this height is to make it comfortable for as many people as possible. It depends on the distribution density of the elbow joint height size. The distribution density should be selected. Generally, the 50th percentile is enough, because the human body size is roughly normally distributed.


The difference between the single size of doors and windows and the size of the hole

The installation of doors and windows needs to leave a gap between the wall and the window frame. The width and height of the single size of doors and windows are generally 1~4cm smaller than the size of the hole. About the size on the quotation: with the size of the hole or the size of the order to make the quotation, different regions have different choices or habits. Therefore, when the area of doors and windows installed in the home is large, it is best to ask the size first, especially when you encounter merchants whose prices of doors and windows are lower than those of the same kind, you can buy a ruler to enlarge the area of the hole if you are not afraid of trouble.


Selection of heat insulation strips

Similar door and window products, heat insulation strips exceed 24mm. If the height of the heat insulation cavity is large, heat insulation cotton needs to be added in the heat insulation cavity to prevent the formation of gas flow in the heat insulation cavity and bring heat transfer. Otherwise, the wider the heat insulation strips, the worse the heat insulation effect. There are two main types of heat insulation strips used in broken bridge aluminum doors and windows on the market, one is PA66GF25 heat insulation strips, and the other is PVC heat insulation strips.

PA66GF25 Insulation Strip: PA66 is a series of modified engineering plastic alloys with high melting point, excellent heat resistance and self-extinguishing properties.

PVC insulation strip: The main raw material is PVC resin powder plus 25% calcium carbonate. The surface of the PA66GF25 insulation strip of the broken bridge aluminum window is a frosted texture with anti-black color, but the PVC insulation strip looks smooth, smooth and anti-white color. The two can be clearly distinguished when put together.


invisible screen window and diamond mesh screen window

invisible screen window are made of aluminum alloy frame, glass fiber material, mesh screen, etc. It has been in the decoration market for many years. The invisible screen window is still ideal for indoor ventilation and outdoor landscape, and can play an anti-mosquito ventilation effect, but it has no protective effect. For children at home, installing a single invisible screen is less secure.

diamond mesh screen window can not only prevent mosquitoes, protection and thieves, but also has the characteristics of high strength, long service life and not easy to rust. Its service life is generally more than 15 years. The thicker the wire diameter of diamond mesh, the higher the strength, the more shear resistance, and the better the anti-theft effect.


The conversion frame of the outer window

The conversion frame of the outer window is a very hidden addition in the door and window. When a window has both a fixed window and an outer window, the conventional method can only allow the glass of the fixed window to be installed outdoors, because a circle of the conversion frame can be saved, one fan saves tens of yuan and hundreds of yuan of cost, but the fixed window is equipped with good anti-theft (especially the lower floor), and the advantages of convenient and safe glass replacement (especially the higher floor or the larger glass area), so the home improvement is also very simple to solve this kind of problem. uses a "conversion frame" to let the pressure line on the fixed frame install indoors, that is to ensure safety, but also for the future replacement of glass, rubber strip to provide convenience, the money is best not to save.


After-sales and Contract

Doors and Windows Whether it is good or not depends not only on the product and installation, but also on after-sales. When purchasing doors and windows and signing a contract, the after-sales service period, warranty scope and whether to charge can be agreed together.

When signing the contract, the information of the purchased doors and windows shall be clearly stated. The quotation sheet can indicate the product series, hardware configuration, opening fan, area, pricing method, installation fee, etc. All items that need to be paid shall be indicated one by one, and the expenses beyond the contract will not be paid.

The second is the design drawing. Each dimension needs to be clearly marked on the design drawing to avoid the discrepancy between the dimension and the design when the finished product is installed. Also agree on the price and payment method, each place's payment requirements are not uniform, agreed in advance to avoid disputes.

the terms of delivery and construction period, installation and acceptance. The agreed construction period is to ensure that the installation of doors and windows can be completed on time without affecting the overall decoration progress. The responsibility for the safety of workers at the time of installation, who is responsible for the removal of the old window, and whether the removal is charged, should also be indicated when signing the contract.
