What kind of door and window seals are good for winter?

1. Add sealing strips to doors and windows.

Heating and air conditioning are normal, but the indoor is not insulated, some old-fashioned aluminum alloy doors and windows and steel windows have no sealing strips, and some new doors and windows sealing strips will have aging problems after a period of use, resulting in indoor heat loss, you can install sealing strips and replace sealing strips.

2. Choose the window glass correctly.

40% of the heat in the winter is related to the heat loss of the window glass, if the original exterior window is a single-glass ordinary window, then it is best to replace it with energy-saving glass with better thermal insulation. The insulation effect of windows mainly depends on the quality of the glass of the window, because the vast majority of the area of the window is made up of glass. When people buy windows, they pay more attention to the frame material of the window and the style of the window, and ignore the choice of window glass.

At present, the window glass that is widely used and has good thermal insulation performance is insulating glass. Several layers of glass are effectively sealed, and molecular sieves are installed to absorb water vapor, and there is no water vapor and dust in the middle of the glass, and the thermal insulation is good.

When choosing window glass, be careful to choose inferior products. When purchasing, we should not only pay attention to the brand of the merchant, look at the quality inspection report of the product, but also carefully identify the thickness of the glass and the empty layer to see whether the product meets the specifications. However, do not fall into the mistake that the thicker the glass and air layer, the better, and pursue the thickness of the glass in order to keep warm.

3. Selection of window frame material.

The window frame is responsible for supporting the main structure of the window, and the sealing and thermal insulation of the material will also affect the warmth of the window. If home decoration has high requirements for indoor thermal insulation, when purchasing windows, it is necessary to pay attention to choosing window frame materials with better thermal insulation performance.

The window frame of the broken bridge aluminum alloy window is connected with resin material, which has the advantages of aluminum alloy doors and windows that are not easy to deform and age, strong and durable, and at the same time cut off the way of heat conduction, and has good sealing, heat preservation and heat insulation.

With the development of the industry, the sealant strip for doors and windows has also been better improved, from the first cheap rubber and plastic, PVC rubber strip gradually transitioned to the application of ethylene propylene diene monomer (EPDM) adhesive strip. EPDM adhesive strip has good elasticity, heat resistance, low temperature impact resistance and aging resistance.

At present, the sealant strip products used to replace EPDM on the market have appeared and have begun to be applied to engineering practice. It is a polyurethane foam sealing strip, commonly known as.

i-eco wrap-around seals. This material is both anti-aging and environmentally friendly, and is an upgraded version of high-grade sealant strips.

Rubber and plastic materials, EPDM, covered sealing strips, and plastic steel door and window sealing strips are all very good.

1. Rubber and plastic materials.

Rubber and plastic is a kind of PVC, the processing equipment is relatively simple, and the investment is also less, the material is very easy to obtain, the color of the finished product is rich, it can also be recovered, and the utilization rate is also very high, so the overall cost is relatively low. Rubber and plastic have a plastic smell, and even have a nasal odor, its elasticity, resistance and weather resistance are worse than the contrast, stretching will recover slowly in the future, and it is greatly affected by temperature.

2. EPDM

EPDM has many advantages, such as very good ozone and oxidation resistance, good heat resistance, and low temperature characteristics. In addition, it also has the advantages of good electrical energy and outstanding stress-strain characteristics, and the extrusion of the product is also relatively stable, and the dimensional accuracy is very high. However, the color of EPDM is more than one by one, and the self-adhesive type and mutual adhesion function are poor.

3. Wrapping sealing strip.

This kind of sealing strip has a very good function, and is an energy-saving, environmentally friendly international third-generation sealing product, made of different materials such as thermosetting core and tough outer skin layer. This ensures that the sealing strip is used in different environments for a long time, resulting in tightening and even deformation. This adhesive strip has a remarkable sound insulation and noise reduction effect and excellent thermal insulation and energy saving.

4. Plastic steel door and window sealing strip.

Plastic steel door and window sealing strip is a new generation of doors and windows that has been widely used in recent years, which is very good than the usual sealing strip of doors and windows with anti-corrosion and weather resistance, and has the effect of noise reduction and heat insulation. The appearance of this plastic steel door and window sealing strip is very bright, which not only has a very good sealing and waterproof function, but also has the role of a beautiful decoration home.

Polyurethane foam sealing strip.

Sealant strips that can be used as an alternative to EPDM have appeared on the market and have begun to be applied to engineering practice. It is a polyurethane foam sealing strip, commonly known as i-eco coated sealing strip. This material is both anti-aging and environmentally friendly, and is an upgraded high-grade sealing strip.

When fixing the glass with sealant caulking, the glass should be squeezed with rubber strips or rubber blocks first, leaving a gap for glue injection, and the glue injection depth should not be less than 5mm, and the glass should be kept from vibration before the glue cures.

If it is an aluminum alloy door and window, you can use a door and window seal in an aluminum store, and if it is a door and window, a building materials store will also buy it.

1. Plasticized PVC base leakage sealing strip: the material is cheap and easy to obtain, with corrosion resistance, wear resistance, combustion resistance, and high mechanical strength; The disadvantage is that the plasticizer in the system is easy to migrate, hardens and becomes brittle with the extension of time, loses elasticity, is not resistant to aging, and has poor weather resistance and low temperature performance. It is generally a dark-colored product.

It is suitable for occasions where the light is not strong, the temperature changes little, and the climatic conditions are not harsh.

2. EPDM sealing strip: excellent comprehensive performance, ozone resistance, high temperature resistance, low temperature resistance, chemical resistance, resistance to a variety of polar solutes, and low relative density. The disadvantage is that the expansion amount is large in general mineral oil and lubricating oil, and it is generally a dark-colored product.

The operating temperature range is -60 +150, and it has been widely recognized in the industry for its excellent comprehensive performance. It can be applied to high temperature, cold, coastal, ultraviolet radiation areas and front-buried medium and high-rise buildings.

3. Thermoplastic vulcanized rubber sealant: it has the flexibility and elasticity of rubber, which can be produced by plastic processing methods without vulcanization, and the waste can be reused. It is a material with a wide range of properties, good heat resistance and cold resistance, small relative density, oil resistance and solvent resistance similar to that of chlorine rot butadiene rubber, and compression set and wear resistance are not very good.

It can meet the requirements of various colors, and the operating temperature range is -40 +150. It can be used in cold, medium and high-rise buildings.

The above is an introduction to what material is good for door and window seals, and this has to be purchased according to your own needs.
