External sunshade roller blinds can be seen in many construction facilities. They have good mechanical strength, heat and sound insulation effects, and good wind resistance. It is mainly used in buildings, mainly to play a role in shading, so it is widely used. Let Zhibo work with you to understand the main functional characteristics and technical requirements of external sun-shading roller shutters.

Features

1) Sun protection

Contrary to the winter people want to warm the room through the sunlight through the glass window, the hot sun in summer is undesirable. At this time, only a small part of the light is reflected by the glass window, and most of it is shot through the glass window. Indoors, as a result, people have put forward the requirements for shading.

Roller shutter windows can reflect most of the sunlight; you can also control the sunlight/light entering the room by adjusting the shading position; if you choose light-colored roller shutter profiles, it will better improve the reflection effect of the sun; its use Basically does not take up space, while keeping indoor furniture/fabrics from direct sunlight.

2) Heat preservation and energy saving

External sunshade roller shutters can greatly save energy for cooling and heating

In summer, the roller shutter window shading system adjusts the amount of sunlight to reduce heat entry, and cooperates with natural ventilation to reduce the cooling load; in winter, all the roller shutter windows can be opened during the day to ensure maximum light and heat entry and increase indoor air Temperature and night are also a barrier against the cold, saving heating energy consumption.

In order to obtain the ideal heat preservation effect, the following points should be paid attention to for the outer sunshade roller shutter:

1. The tightness of the shutter plate closure;

2. The airtightness of the contact part between the shutter plate and the shutter cover;

3. The tightness of the guide rail;

4. The tightness of the guide rail and the wall;

5. The airtightness of the roller shutter window seat bar and the window sill;

6. Thermal insulation performance of roller shutter cover

3) Sound insulation and noise reduction

The external sunshade roller shutter installed on the outside of the glass window can greatly improve the sound insulation effect of the window. The closed shutter window can reduce the noise by 16dB. If combined with the thermal insulation glass window, a comprehensive sound insulation effect of 35dB can be obtained.

4) Security and anti-theft

Use high-strength, high-density profiles; inside the shutter doors and windows can be equipped with anti-push and anti-prying devices; doors and windows cannot be opened from the outside after they are closed, and the time controller can be used to create an unmanned and human-like environment.

5) Comfortable and private

Closed roller shutter windows can replace curtains to block the sight from the outside; protect you and your family from being disturbed.

6) Weather resistance

Roller shutters installed outdoors can effectively resist wind, rain, snow, hail, damp and other bad weather; strong wind resistance prevents your home windows from being hit by any gale; the anti-corrosion performance of the profile curtains, Prevent your home windows from being corroded by the city’s acid rain and keep them beautiful as new; efficient airtight performance prevents the cold in the north from hitting your warm home; prevents the damp in the south from damaging your beloved walls and furniture Items; make your home very comfortable and pleasant all year round.

Skills requirement

The outer sunshade roller shutter is mainly composed of roller shutter bundles, shafts, guide rails and other parts. There are also some basic technical requirements for each component:

1. Due to the long-term exposure of the outer sunshade and roller shutters, the materials of each part have certain anti-corrosion and anti-weathering functions.

2. In the structural design, it is necessary to ensure that the blades and profiles that make up the roller shutter board cannot move in series with each other, so as to ensure the normal function of the roller shutter device.

3. In the completely closed state of the roller shutter, each leaf must be well sealed without light leakage; when the shutter is not completely closed, the small holes between the leaves must be exposed, which can transmit light well.

4. When using the pull-tape drive, ensure that the pull-out reel and the pull-out direction of the pull-tape are in the same plane. No sharp corners are allowed in the strap guide. The drawstring must be a flat woven fabric with reinforced edges, and the bandwidth should not be too small.

5. When using a manual drive device without a crank device, the pulling force on the strap cannot exceed a certain limit.

6. All parts including joints must be strong and durable, and be able to withstand certain distortions under certain wind or other external forces.
