This is a heat-shielding film for windows that can be removed with a self-adhesive sheet that does not have adhesive (glue) on the sheet. By simply applying it, it retains the light transmission of the window glass while cutting approximately 99% of ultraviolet rays, which are the cause of sunburn and deterioration. Additionally, it cuts about 70% of near-infrared rays, which are responsible for heat, and measurements taken after application showed a temperature difference of up to 12°C at the window. Furthermore, it is expected to provide a glass shattering prevention effect against debris from typhoons and other sources. The recommended replacement period is 7 years (the replacement period may vary depending on usage conditions and environment).

• Glass construction

With a visible light transmittance of over 70%, it boasts a high transmittance, allowing the glass to maintain its beautiful transparency even after painting. It cuts over 80% of the near-infrared wavelength range of 980 to 1280 nm, which causes discomfort by piercing the skin. By simply applying it to windows, it can suppress the indoor temperature rise by 5 to 10°C, resulting in an expected energy-saving effect of about 20%. Additionally, it cuts over 90% of ultraviolet rays, protecting the body from spots and freckles, and preventing browning and deterioration of furniture and products.

• Glass construction accessories and films

The Obayashi-style greening method has a significant feature of using "E Soil," a non-decaying bark soil developed by Obayashi Environmental Technology Research Institute Co., Ltd. "E Soil" is made from specially processed bark of cedar and cypress, and is a 100% natural recycled building material. The characteristics of "E Soil" are as follows: 1. It has the natural antibacterial and insect-repelling properties of cedar and cypress, which suppresses the growth of root rot fungi and other bacteria in the soil, thereby reducing the occurrence of diseases in grass and flowers. 2. Since the bark of cedar and cypress does not decompose, it maintains its fibrous state for a long time, eliminating the need for soil replacement or addition. 3. It is lightweight, allowing it to accommodate the load-bearing capacity of existing structures. 4. It does not get blown away by the wind or washed away by rain, making it easy to install by simply placing "E Soil." There is no need for the drainage layer typically required in conventional greening. 5. Due to its high gas phase ratio, the soil can be kept shallower than usual, while sufficiently storing and supplying oxygen, water, and nutrients to plants, promoting good root growth and supporting plant development over many years. These features allow for low-cost installation, and after installation, the use of pesticides and other chemicals is almost eliminated, enabling low maintenance.

• Wall and rooftop greenery

By painting the roof and exterior walls, it efficiently reflects solar heat and mitigates the rise in temperature inside the building. ProTsubaru is a residential paint developed by Japan ProTsubaru Co., Ltd., under a technology licensing agreement with the Japan Aerospace Exploration Agency (JAXA). Among various JAXA technologies, it has particularly advanced the paint materials that withstand high temperatures during rocket atmospheric flight, integrating unique technologies and exploring alternative materials to meet various needs, resulting in a thermal control paint. ProTsubaru employs a selected acrylic silicone resin, which causes the resin components to come together and bond as water evaporates, creating a new, strong paint film. This is the only technology that achieves a homogeneous and stable paint film from the surface to the interior. With special pigments and ceramic balloons, it has high thermal control properties and excellent dirt-repellent performance, allowing dirt to wash away with rain, thus protecting the building over the long term and maintaining durability. It is available in a wide range of colors, with 20 standard colors and the option for custom mixing. Photo provided by the Japan Aerospace Exploration Agency (JAXA).
