Curtain wall locates between the indoor space and outdoor space and play a role in both insulation and communication. Besides sound insulation, thermal conductivity, light transmittance adjustment & controlling, weatherproofing, curtain wall also contributes to the ventilation and air exchange of indoor space (e.g. add vents or air exchange device on the curtain wall). The ventilation products integrated within the curtain wall mainly include ventilation louver and specialized ventilation device etc.

Aluminum Alloy Rain-proof Louvers

Used in ventilation projects , the rain-proof louver with a long-term of required ventilation for engine room or other public places, comprising of gully rain-proof leaves and side frame with drop box .
Even in the pouring rain, the louvers not only can effectively prevent rainwater into the interior, but not formed the water curtain on the windward of entire rain-proof louvers, thus ensuring the normal design ventilation requirements.
The main technical features are as follows:
●Used as vents to connect with fresh air and exhaust pipeline tube from the building ventilation system.
●Connected directly to the indoor space and used as the duct for natural ventilation, e.g. at MEP storey or refuge storey etc.
●Can be used to separate the ventilation vents, also be embedded in the required ventilation of the various curtain wall systems, to realize closely combination with a variety of curtain wall systems.
●Adjusting and rotating the blade by electric or manually so that the louvers can be opening and closing, forming electric or manual adjustable rain- proof louvers. Also, you can achieve the automatic control for the louvers by a linkage both the ventilation system and fire system.
●To select the appropriate finish of aluminum and color as required, to meet the requirements on anti-corrosion and decorative effectiveness.

Aluminum Sand-proof Louvers

The sand-proof louvers are primarily used with ventilation requirements of power plant steam room, boiler room and building equipment layer in larger sand area, It not only can effectively trap sand in the air, but also with a function of strong rain-proof in the rainy season.
The main technical features are as below:
●Used as vents to connect with fresh air and exhaust pipeline tube from the building ventilation system.
●Connected directly to the indoor space and used as the duct for natural ventilation, e.g. at MEP storey or refuge storey etc.
●Can be used to separate the ventilation vents, also be embedded in the required ventilation of the various curtain wall systems, to realize closely combination with a variety of curtain wall systems.
●Not only it has a function of good sand collection, but also with good rain-proof performance, the good rain-proof louvers in the rainy season.
●Can be selected in aluminum alloy profile or Stainless steel etc.
●To select the appropriate finish of aluminum and color as required, to meet the requirements on anti-corrosion and decorative effectiveness.

Aluminum Alloy Acoustic Louvers

Acoustic louver is one type of noise control louvers , one is the ventilation for heat elimination, another is the noise elimination, acoustic, deduct or isolate the noise to spread. It is more suitable for the requirements of ventilation and noise reduction on industrial and commercial projects, as the entrance where the fresh air entering in the ventilation system, the return air mouth in corridor, cooling tower ventilation silencers, noise barriers air conditioning vents and cooling vents and other kinds of occasions to meet the requirements of ventilation, lighting, building envelope and control of radiated noise.
The main technical features are as below:
●Can be used as vents, various types of machine rooms, equipment rooms with the requirements of ventilation and acoustic.
●Connected directly to the indoor space and used as the duct for natural ventilation, various occasions required for the ventilation and acoustic.
●Can be used as the opening with the requirements of separate acoustic, also be connected with various types of curtain wall systems, to achieve the closely connection with various types of curtain wall systems.
●To control the outgoing noise radiation, to achieve the noise reduction with good effect.
●Can be selected in aluminum alloy profile or Stainless steel etc.
●To select the appropriate finish of aluminum and color as required, to meet the requirements on anti-corrosion and decorative effectiveness.
