Prefabricated Sunshade Panel Outside House
The prefabricated sunshade panel outside a house is a building component used to block sunlight and regulate the indoor light and thermal environment, offering functions such as energy conservation, sound insulation, and protection of the building structure. The following provides an introduction from four aspects: functional roles, material costs, installation points, and types and styles.
Functional Roles:
The core function of a prefabricated sunshade panel is to regulate the indoor light and thermal environment. Its effects vary depending on the orientation of the windows: For south-facing windows, installing horizontal sunshade panels can effectively block direct sunlight in summer, reducing indoor radiant heat by about 15%; in winter, when the sunlight angle is lower, it allows sunlight to enter the room, achieving an energy-saving effect of 'warm in winter and cool in summer'. For east- and west-facing windows, if no sunshade panels are installed, the glass surface temperature can reach 62°C, raising the indoor temperature by more than 4°C within half an hour, significantly increasing air conditioning energy consumption (electricity bills can be 2.7 times those of neighbors); vertical or honeycomb louvered sunshade panels can accelerate heat dissipation while avoiding blocking ventilation, reducing energy consumption. Additionally, in public and industrial buildings, sunshade panels can extend the service life of glass curtain walls by reducing direct exposure to sunlight and provide certain sound insulation and protection functions.
Material Costs:
Material selection directly affects the performance and cost of sunshade panels. Aluminum alloy offers high strength and weather resistance but comes at a higher price, with a market price range of 32-1047 yuan per square meter in 2026, suitable for scenarios requiring high durability; PC panels (polycarbonate panels) offer excellent cost-effectiveness, with transparent models from Funaijia selling over 3,000 units per month, making them a good choice for ordinary households. Additionally, customized products vary greatly in price, such as outdoor transparent polycarbonate rain-proof sunshade awnings in Baoding, Hebei, priced at 248 yuan per square meter, and 8mm hollow blue sunshine panels in Hengshui, Hebei, priced at 26 yuan per square meter, allowing users to choose based on their budget and needs.
Installation Points:
When installing, space must be reserved for thermal expansion and contraction, with a gap of 2.8 millimeters per meter length to prevent panel deformation; sealing materials must be neutral adhesives, as acidic or alkaline adhesives may corrode the panels. For houses with severe westward sun exposure, improper sealing leading to water leakage may cause cracks (up to 1 millimeter) in solid wood furniture, so installation quality must be strictly controlled.
Types and Styles:
According to control methods, they can be divided into mechanical, electric, and intelligent types, with blade shapes including single-wing, double-wing, and airfoil types; installation methods include horizontal, vertical, and combined types to suit different building orientations and sunshade needs. In residential buildings, common styles include canvas temporary sunshades, fixed plastic panel external sunshades, retractable canvas sunshades, forward-cap-style gypsum board sunshades, arch-shaped sunshades, movable baffle sunshades, and electric sunshade curtains, allowing users to choose flexibly based on architectural style and functional needs.
