High insulation and heat shielding performance. External blinds available in 26 color variations.
"Achieve a life without relying on air conditioning with high insulation and heat shielding performance." ★ External blinds, a common practice in environmentally advanced Germany. ★ Ideal for Japan's hot summer climate. Even if you block the intense summer sunlight with indoor blinds or curtains, heat continues to accumulate by the window. Relying solely on air conditioning to dissipate heat indoors is inefficient. The rational method to block this sunlight from outside the window is "external blinds," which are already standard in environmentally advanced Germany. External blinds create shade outside the window and share a mechanism with traditional Japanese sunshades like "yoshizu" and "sudare," making them the best solution for solar radiation in Japan's climate. "In summer, about 70% of energy flows in through the windows. The fundamental energy-saving measure is 'window insulation.'" You often hear the terms "high insulation" and "external insulation." This refers to buildings designed structurally to minimize the influence of outside temperatures on indoor conditions, allowing for a comfortable indoor temperature with less energy. Among these, the most critical point for improving a building's energy efficiency is the "windows." By blocking heat from direct sunlight in summer and allowing it in during winter, significant savings on heating and cooling costs can be achieved.

Detailed information
-
Cuts solar energy from window glass by about 80%. The external blinds from "Valema" have a low solar energy transmittance rate, blocking about 80% of it 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 ordinary glass (single) without sunshades on the windows is set at 100%, the air conditioning operating rate for a room with external blinds installed is only 25%. Compared to the 75% for indoor blinds, this is about one-third, making it economical.
-
Supports a maximum size of 5m x 5m. Large windows are essential for creating an open space that incorporates natural light. However, large openings also 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 the view and the passage of wind, privacy is also well secured. Concerned about outside gazes? They can be blocked by slightly darkening the interior. The interior is hard to see from 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 outdoors.
-
Slats are available in 26 colors. The slats of "Valema" 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, or to serve as accents in design. They contribute to the beautiful scenery of the city 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. Depending on the type, it can vary, but 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 feeling of confinement. In fact, having the privacy screen outside the building allows you to feel the spaciousness of the interior even more than indoor blinds.
-
Slats with eyelets The cable guide type slats have cable holes (holes for passing cables). It is also possible to attach a resin part called an eyelet to reinforce the cable hole. (Example of flat slats)

Fixed with a tension angle. The cable is a steel cable coated with plastic on the surface. This protects the slats from the wind. It is securely fixed with a tension angle attached to the lower end.
