Measures against heatstroke! External blinds to protect the elderly who have difficulty regulating body temperature.

basic information

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 near the windows. Relying solely on air conditioning to dissipate this heat is inefficient. The rational method to block sunlight from outside the windows is "external blinds," which are already standard in Germany, an environmentally advanced country. These 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 basic energy-saving measure is 'window insulation.'】 You often hear the terms "high insulation" and "external insulation." This refers to buildings designed structurally to be less affected by outside temperatures, allowing for a comfortable indoor temperature with less energy. Among these, the most crucial 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.

  Cuts solar energy from window glass by about 80%. The external blinds from "Valema" have a low solar energy transmission rate, blocking about 80% of it outside the window. Since they are installed outdoors, the air between the window and the blinds circulates, making it difficult for heat to accumulate and increasing 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 a rise 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 we consider the air conditioning operating rate of a room using regular glass (single) without sunshades on the windows to be 100%, the air conditioning operating rate of a room with external blinds installed is only 25%. Compared to the 75% of indoor blinds, it 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 also have the drawback of causing excessive increases in room temperature. With Valema, which can be installed in large 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. The gaze from outside can be blocked by slightly darkening the interior. It is difficult to see inside 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 "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, or to serve as accents in design. They contribute to the beautiful scenery of the city through various buildings, including single-family homes.

• 

  Fix the rail guides on both sides of the window. Typical external blinds are fixed to the wall or ceiling (hidden inside the cover panel). The self-standing type secures the left and right guide rails on both sides of the window, providing strong support for the blinds.
