Beautiful facade, balcony, and townhouse sunshade models 2025

Sun Louver is an architectural structure that has the function of shading, blocking rain and wind, protecting the building from direct environmental impact. The 6 facade sun louver models leading the market trend this year include: Box-shaped louver (most popular, easy to construct), 85C louver (C-shaped cross-section 85mm wide), 132S louver (S/Z-shaped cross-section 132mm wide), diamond/elliptical louver (sophisticated design), willow leaf louver (softly curved) and bullet-shaped louver (modern, angular).

A 2023 study by Shenzhen University demonstrated that exterior shading devices, including sunshades, can reduce the cooling load of buildings by 25-40% by directly blocking solar radiation.

According to a market survey in March 3, the price of completed sunshade louvers ranges from 2025 - 150.000 VND/m², depending on the material, size and installation method. To optimize sunshade efficiency, Kosmos recommends that East and West-facing houses should install vertical louvers with a tilt angle of 2.000.000°, while South and North-facing houses are suitable for horizontal louvers, with tilt angles of 30° and 37° or more, respectively.

What are the advantages of sunshades?

Sunshade louvers offer three main advantages: Effectively reduce heat for living spaces, protect users' health by blocking ultraviolet rays, and create a unique appearance for architectural works.

• Sun protection, heat reduction: According to a 2024 study by the Vietnam Institute of Construction Science and Technology conducted on 50 projects in Hanoi and Ho Chi Minh City, sunshades reduce up to 90% of heat absorbed through glass doors, helping to save 30-40% of electricity costs for air conditioning systems.

In particular, with the moving louver, users can adjust the tilt angle from 0-180°, precisely controlling the amount of natural light entering the house, creating an airy space and optimal energy savings.

• Block UV rays, protect health: UV (ultraviolet) rays are harmful to the skin and eyes. According to the World Health Organization (WHO), long-term exposure to UV rays can increase the risk of skin cancer, cataracts, and macular degeneration.

Thick sunshades act as a “shield”, blocking up to 90% of UV rays from entering the house, providing comprehensive health protection for the whole family. Especially for families with young children and the elderly, this is an extremely important benefit.

• Enhance aesthetics, create unique highlights: With a variety of materials (powder-coated aluminum, composite wood, etc.), designs (box-shaped, willow leaf, bullet, Z-shaped, C-shaped, diamond/elliptical, etc.) and colors (monochrome, imitation wood, etc.), sunshade louvers are not only a shielding item but also a unique architectural highlight.

Surveys by the Vietnam Association of Architects show that box-shaped louvers are often suitable for modern minimalist styles, willow leaf louvers create accents for Asian-style buildings, while bullet-shaped louvers often appear in industrial-style buildings. The trend in 2025 is leaning towards a combination of functionality and aesthetics with louver models that have smart adjustment capabilities.

What is the general structure of a sunshade project?

A complete sunshade system includes louver blades and louver frames firmly connected together with specialized accessories such as bolts, screws, locating pins, anchors, etc. Including:

• The louvers are the main part responsible for the function of blocking sunlight, rain, and wind. These louvers are made from many different materials such as aluminum, wood plastic, natural wood, cement, concrete, etc. with a variety of shapes such as rectangle, square, Z, C, diamond, ellipse, willow leaf, etc. They are arranged parallel, perpendicular or at an angle to the horizontal to form a unified block.
• The skeleton is the part that helps fix the slats, ensuring stability and firmness for the entire system. The skeleton is usually made of aluminum, stainless steel or square steel, with anti-corrosion and heat-resistant electrostatic paint.

How many types of balcony sunshades are there?

There are 2 types of facade sunshades: fixed and moving, specifically:

• Fixed sunshade: The louvers are fixed in one position and cannot be adjusted in angle. This type is often used for buildings with stable orientation and less affected by storms such as North and South facades.

According to Kosmos Vietnam, the advantages of fixed sunshades are low installation costs, quick and easy construction. However, the disadvantage is that it is not possible to actively adjust the amount of sunlight and wind entering the house.

• Motion sunshade: The louvers can be rotated or slid to adjust the angle and amount of light entering. This type is more flexible, suitable for buildings with seasonal orientation or strong impact of storms such as East and West facades.

According to statistics from 200 projects of Kosmos Vietnam, the advantage of movable sunshades is the ability to be flexibly adjusted, optimizing the effectiveness of sunshade and wind protection, helping to save an additional 15-20% of electricity costs compared to fixed louvers. However, the disadvantage is that the cost is 30-50% higher and requires periodic maintenance every 6 months.

6 popular facade sunshade models?

According to the Q1/2025 construction materials market report of the Vietnam Construction Materials Association, the current Vietnamese sunshade louver market is extremely diverse with 6 most prominent louver models accounting for 85% of the market share: Box-shaped louvers, 85C louvers, 132S louvers, diamond/elliptical louvers, willow-leaf louvers and bullet-shaped louvers.

The current trend is shifting from simple louver patterns to more complex designs with the ability to integrate smart technology, forecast to grow 12-15% per year in the period 2025-2030.

Frequently asked questions when constructing sunshade louvers

How to install sunshade louvers for west and east facing houses?

For houses facing West and East, vertical sunshades (also known as vertical blinds) are the most suitable choice. Because the sun will shine horizontally in these two directions, installing vertical blinds will help limit direct sunlight into the house.

According to information collected by Kosmos, to optimize sun protection, you should adjust the angle of the slats to about 30°.

How to install sunshade louvers for houses facing south and north?

For houses facing south and north, where the sunlight is not too harsh, horizontal sunshades (also known as horizontal bars) will be the optimal choice. Because the sunlight shines from above, the horizontal bars will have a more effective effect of blocking the sunlight.

According to a survey by Kosmos with more than 500 construction workers, for the South direction, the installation angle of the sunshade louvers should be from 37° or more. Meanwhile, for the North direction, the installation angle should be from 10° or more, because the amount of sunlight in the South direction is often greater than in the North direction.

How much does it cost to complete the construction of sunshade louvers for a townhouse?

The price for completing the construction of sunshade louvers for townhouses is about 150.000 - 2.000.000 VND/m² depending on the material, size, specifications,... excluding VAT. The price was updated in March 3 and is for reference only.

Should I use wood plastic or aluminum sunshade?

The choice of using wood-plastic or aluminum slats to shade the house depends on the needs of the user.

• Wood plastic sunshade slats are made from composite wood plastic (HDPE/PVC plastic, natural wood powder, additives), usually have wood grain color and rectangular or elliptical cross-section, durability from 10 - 15 years with price 20 - 30% cheaper than aluminum slats.
• Aluminum sunshade louvers are made from high-grade aluminum alloy, with a variety of colors (monochrome to wood grain) and designs (willow leaves, bullet heads, Z-shaped, C-shaped, etc.), with a durability of 15-25 years and a price 20-30% higher than wood-plastic louvers.

With more than 10 years of experience in the field of distributing interior and exterior decoration materials, Kosmos Vietnam has constantly searched for quality sources of supply, promptly responding to the pace of modern life. In early 2025, Kosmos launched ASA wood plastic rotating slats. The ASA rotating louver remote control system operates with a control range of up to 10m, allowing users to precisely adjust the rotation angle from 0-180 degrees. The louver covers 15-20m²/day and only requires periodic cleaning with a damp cloth every 6 months to remove dirt.

With outstanding advantages in terms of heat insulation, UV protection and creating impressive architectural highlights, sunshades are becoming a popular trend in green construction and energy saving.
