Osaka Airport also adopted! The exterior blinds for buildings 'Valema' recognized by the world.

basic information

Terms like "high insulation" and "external insulation" are often heard and seen. This refers to buildings that are structurally designed to be less affected by outdoor temperatures, allowing for a comfortable indoor temperature with less energy consumption. Among these, the most important point for energy efficiency in buildings is the "windows." By blocking heat from direct sunlight in the summer and allowing it in during the winter, significant savings on heating and cooling costs can be achieved. ★As parts incorporated into facade design 【Roll Slat Specification】【Flat Slat Specification】 ● A type that holds both ends of the slat with rail guides ● Various types of rails are available, making it possible to install on any exterior wall or window ● Smooth operation with minimal noise ● There are two types of slats: roll slat and flat slat. ● The rail guide type slats are equipped with guiding nipples fixed with three-point welding at both ends.

Detailed information

• 

  Cuts solar energy from window glass by about 80%. The external blinds from "Valema" have a low transmittance of solar energy, blocking about 80% outside the window. Because they are installed outdoors, the air between the window and the blinds circulates, making it difficult for heat to accumulate, thus enhancing heat insulation. In contrast, with indoor blinds, the heat that accumulates between the window and the blinds or curtains leads to a greenhouse effect due to reflection, resulting in an increase in room temperature.

• 

  The air conditioning operating rate is about one-third when indoor blinds are installed. This can significantly reduce air conditioning costs. If the air conditioning operating rate for a room using regular glass (single) without sunshades on the windows is set at 100%, the operating rate for a room with external blinds installed is only 25%. Compared to the 75% operating rate with indoor blinds, this is about one-third, making it economical.

• 

  Compatible with a maximum size of 5m x 5m. Large windows are essential for creating an open space that incorporates natural light. However, large openings have the drawback of causing the room temperature to rise too much. With Valema, which can be installed in openings up to 5m, you can enhance the design of the building while keeping the exterior looking sleek.

• 

  In addition to a view and a pathway for the wind, privacy is also well secured. Concerned about outside gazes? They can be blocked simply by slightly darkening the interior. The interior is hard to see from the outside, while the view from inside to outside is clear. Changing the angle of the slats does not obstruct ventilation, allowing you to secure privacy while inviting in the pleasant natural breeze from outside.

• 

  Slats are available in 26 colors. The "Valema" slats come in a rich variety of 26 colors. For metal components such as cover panels and guide rails, you can choose from about 200 colors. They can be freely coordinated to harmonize with the building's exterior walls and facades, as well as to serve as design accents. They contribute to the beautiful scenery of the town through various buildings, including single-family homes.

• 

  Achieve an open view with slat widths of 60mm to 100mm. The standard slat width for blinds is 80mm. While it varies by type, you can choose from almost 60mm to 100mm according to your preference. With ample spacing between the slats during use, even when installed across the entire window, the view from indoors is excellent, and there is no sense of confinement. In fact, having the privacy barrier outside the building allows you to feel the spaciousness of the interior even more than with indoor blinds.

• 

  Rail guide type slats are equipped with two fixed guiding nipples welded at both ends, ensuring stability against wind and smooth raising and lowering. (Example of roll slats) Plastic eyelets can also be added as an option. (Standard equipment for roll slats)
