In the door and window system

If profiles are the bones of doors and windows,

So hardware accessories are the heart of doors and windows.

Both profiles and hardware are the core of doors and windows,

Who should the immune system of doors and windows be?

The answer is - sealing strip

Door and window sealing strips are mainly used as elastic strip or rod materials on building door and window components (such as glass and pressure strips, glass and frame sashes, frame sashes, and between sashes).

Although door and window sealing strips may not be eye-catching, they have a great effect! As one of the important factors affecting the quality of doors and windows, sealing strips with good flexibility, oxidation resistance, and erosion resistance play a crucial role in sound insulation, shock resistance, dust prevention, insulation, and other aspects of door and window sealing. They play a vital role in the overall performance of doors and windows, including waterproofing, sealing, and energy efficiency.

Types of sealing strips

1. Modified PVC rubber strip

The quality of modified PVC rubber strips varies and the price is relatively low; Modified rubber strips on the market are often filled with waste materials and substitute plasticizers, resulting in poor overall elasticity, easy hardening, pungent odor, and short service life.

2. Vulcanized EPDM rubber strip

The vulcanized EPDM rubber sealing strip has stronger sealing elasticity and durability than PVC rubber strip, but the product (sulfur-containing) cannot be reused and is not environmentally friendly, which is not the environmentally friendly rubber strip advocated by the country.

3. EPDM (Ethylene Propylene Diene Monomer)

EPDM (Ethylene Propylene Diene Monomer copolymer of ethylene, propylene, and non conjugated diene) is a new material developed on the basis of imported technology from abroad and domestic independent research and development. The EPDM rubber strip originally used for automobiles is gradually being applied to building doors and windows; Its high-quality antioxidant, weather resistance, flexibility, and long-term stability in high/low temperature environments have established its indispensable position in door and window sealing.

Distinguishing the quality of sealing strips

1、 Measure tensile strength

As a sealing material, the rubber strip should have a certain tensile strength (standard requirement: strength≥ 5Mpa). Generally speaking, the higher the adhesive content of the sealing strip, the better its tensile strength, service life, and sealing effect.

2、 Smell the scent

Smell the rubber strip with your nose for any unusual odor. The normal PVC material adhesive strip may have a slight alcohol odor, but there is rarely any odor (such as sulfur odor).

3、 Testing method

Wrap the sealing strip tightly around the profile as much as possible, place it on the roof or in a sunny place for a period of time, and observe whether the contact surface between the profile surface and the sealing strip is stained or discolored, whether the dust on the surface of the sealing strip is yellow (oil is easy to absorb soil), whether there is oil leakage, and whether it is dirty on hands.

4、 Observation method

Some low-quality rubber strips may not have a very shiny surface; After stretching back and forth several times, a small amount of powder will appear on the surface of some sealing strips with added heavy calcium.

Quality of New Residence

Doors and windows are endowed with deeper connotations

In modern urban life

Besides redeeming the window

Sunshine, breeze, and beautiful scenery, while living an ideal life

We also need to address issues such as noise, rainwater, and thermal insulation

Issues closely related to human habitation and daily life

When sealing strip+insulated glass+Suifu doors and windows

When the Trinity is present

Life will present another scenery

Significantly reduce noise! Super sound insulation

The multi cavity profile system, stable sealing system, and large insulated glass system are integrated into a three-layer sound insulation system, creating a more soundproof, quiet, and comfortable living environment for families. According to testing, the Suifu Broken Bridge Window Three in One Sealed Sound Insulation System can reduce outdoor noise to 35 decibels.

Wind and rain resistance! Extra safe

When the storm comes, doors and windows (sealing, drainage, safety) are an important line of defense. The three sealing systems inside and outside Suifu doors and windows and the profile drainage structure of the high and low structure complement each other, which can drain the accumulated water in rainstorm in time, ignoring the rain and fearless seepage. The aluminum profiles of Suifu doors and windows are made of original building standard strength aluminum profiles, with stable alloy composition: stronger oxidation resistance and longer service life; The wind resistance strength is two to three times that of ordinary aluminum alloy.

There is a way to save energy! Thermal insulation

Summer heat and winter cold are good opportunities for energy-saving doors and windows to showcase their skills. The bridge broken casement windows and sliding window systems of Suifu doors and windows use scientific and reasonable sealing profiles, flexible and anti-aging EPDM rubber strips for seamless sealing and overlapping, and super large glass hollow layers for protection, which greatly improve the air tightness and thermal insulation of doors and windows, reduce the loss of indoor temperature, greatly reduce the energy consumption of air conditioning and heating, and save electricity and money.

Customize your exclusive aluminum alloy doors and windows: Suifu Door and Window Product Series (swing doors/windows, sliding doors/windows, heavy-duty folding doors) can be modern or simple, elegant or generous, luxurious or rustic; Do the best for what you want! In addition to shedding busy work, let you carefully enjoy life and enjoy comfortable quality.
