Contributing to Addressing Climate Change through Products and Services

Policy

The Sanwa Group contributes to the realization of an enriched, sustainable society by promoting mitigation and adaptation that reduces or prevents the effects of climate change through business activities.

Sales Progress of Products Contributing to Addressing Climate Change (consolidated)

Worldwide, the Sanwa Group supplies a wide array of products that address climate change using two separate approaches: mitigation by reducing emissions of CO2 and other greenhouse gases; and adaption by responding to the various phenomena brought about by climate change.
We track Japanese, North American (ODC), European (NF Group), and Asian sales of products that contribute to the mitigation of climate change and products that contribute to adaptation to climate change. In FY 2020, sales in the first category (mitigation) totaled ¥68.6 billion (16.1% of consolidated net sales), while sales in the second category (adaptation) reached ¥11.2 billion (2.6%).

  • "Madomore Screen S Built-In Mesh Screen Type"
    (Sanwa Shutter Corporation)
  • Environment Technology Verification Logo

To improve cooling, the mesh screen built into the shutter box can fully cover the sash to lessen the penetration of solar heat in summer. This was demonstrated as a solar-shielding screen door (a technology that lessens the penetration of solar heat by covering the entire window with a screen door) in the 2009 Environmental Technology Verification (ETV) Program by the Ministry of the Environment.

Products That Use Renewable Energy

SUNGATE Solar and Madomore Screen S Solar Type are eco-friendly products that can be operated just by using renewable energy from solar panels.

  • "SUNGATE Solar" solar power system
    (Sanwa Shutter Corporation)

    This shutter gate for residential use opens and closes using the natural energy of the sun.
    Since there is an onboard battery, these products can be used as an emergency power source for electrical products in the event of a disaster.

  • "Madomore Screen S Solar Type"
    (Sanwa Shutter Corporation)

    This environment-friendly window shutter has a built-in solar panel and opens and closes using solar power.
    Power is supplied from a solar panel and a battery attached to the shutter so that there is no need for onsite electrical work.

Greening Products

Rooftop greening and wall greening have the energy-saving effect of moderating heat islands and decreasing air-conditioning loads, as well as CO2 absorption, which contributes to mitigating climate change.

  • "Coffret Garden" rooftop greening system
    (Sanwa Shutter Corporation)

    In addition to enhancing the landscape, this product supports comfortable living environments by reducing the temperature increase inside the garage and reflection of heat into the main building in summer.

  • "Aquavert" wall greening system
    (Showa Front Co., Ltd.)

    This system is wall greening system that combine building faced and plant. This is jointly developed with Sakata seed corporation, realized high sense of design and safety.

Climate Change Adaption Product Groups

Waterproof Products

In recent years, natural disasters due to climate change and abnormal weather have been increasing, and catastrophic floods caused by large typhoons and sudden, record-setting downpours have been more frequent. As an adaptation strategy to such changes and a measure to prevent urban flood damage, our waterproofing products contribute to the safety of cities by protecting entrances to buildings and underground shopping malls from flooding.
Demand for this product range is expected to see significant growth in the coming years due to the ability to save lives and property from floods in a world in where global warming is intensifying.

Water Guard Waterproof Shutter
(Sanwa Shutter Corporation)
Water Guard Single-tight Door
(Sanwa Shutter Corporation)
Water Guard Double-tight Door
(Sanwa Shutter Corporation)

The industry's first waterproof electric panel shutter can be used as a shutter for security and it resists flooding up to 3 meters in an emergency.

Easy to operate, it can handle up to a flood level of 2 meters. A steel door that can also be used as a fire door.

Supports the design range (2,500 mm x 3,000 mm) required for waterproof fittings defined by the Japan Sewage Works Agency. With a high-strength structure that can withstand tsunami loading, it is ideal for machine room and equipment room entrances.

Development History of "Water Guard Waterproof Shutter"

Sanwa Shutter Corporation's Water Guard Waterproof Shutter, launched throughout Japan in October 2014, is an electric panel shutter that resists flooding up to 2.5 meters in height. It can also serve as a shutter for security purposes for daily use. When the threat of flooding is detected, the shutter is made watertight by sealing the shutter closed and pressing the compression button to put the compression structure into operation.

The impetus for development was the 2011 Great East Japan Earthquake. The city of Sendai in Miyagi Prefecture incurred extensive damage from the tsunami, but the wastewater treatment plant building at Sendai Shiogama Port remained unscathed because steel doors had been installed in the engine room. After receiving this information, Sanwa Shutter Corporation puts its efforts into developing waterproofing products, and went to work on development of waterproof doors and waterproof shutters. In the development stage, the development of rubber that could withstand the water pressure and suppress leakage took time, but Sanwa Shutter Corporation was able to develop the industry's first waterproof shutter in less than a year.

Our diverse product lineup meets requirements for expectedly deep floods, use case, size, and location, among others. Our lineup includes waterproof panels and sheets that can be installed quickly and easily.

  • Apia Guard Okudake Railless model
    (Suzuki Shutter)

    Waterproof panels specifically for front entrance sashes can be set up without having to install rails. The panels are made from three lightweight aluminum subpanels that can be easily assembled without tools.

  • アピアガード 防水シートⅢ(鈴木シャッター)
    Apia Guard Waterproof Sheet Ⅲ
    (Suzuki Shutter)

    This sheet is assembled from pieces that fit into bottom and side rails, enabling it to be set up quickly and easily—wherever it is installed. Sheets are available in widths up to 8 meters, and they protect against water up to 1 meter deep.

Products with high Wind Resistance

Disaster risks, such as wind damage, are predicted to go up as climate change increases, and in recent years massive typhoons have occurred almost every year.
Due to increased awareness of the importance of disaster prevention/mitigation and national disaster resilience, advanced wind-resistance that factors in unprecedented large-scale disasters are more frequently being required for openings at commercial buildings, factories, distribution centers, and homes.

  • "High-strength shutter and wind-resistant guards"
    (Sanwa Shutter Corporation)

    A high-strength shutter optimally suited for large openings in commercial buildings, factories, airports, etc., where even more advanced wind pressure-resistance is required, or for openings in coastal areas, truck berths for large logistics warehouses, and upper floors. High-strength wind-resistant hooks and integral steel wind-resistant guiderails are standard.

  • Integral steel guiderails

    Beginning with guiderails that were previously welded and assembled, we have developed an integral-shaped steel guiderail. Assembly without welding has improved productivity in plants and ensured more consistent quality.
    Also, by reducing the weight of guiderails by approximately 30% to 50%, we have lowered the environmental burden.

  • "Madomore wind-resistant guards"
    (Sanwa Shutter Corporation)

    A high wind pressure-resistant window shutter that protects window glass from flying objects caused by strong winds such as typhoons.
    By ensuring maximum wind pressure resistance (negative pressure) of 2,400 Pa —three times more than conventional products— Madomore guards can be used not only in detached houses but also in mid-rise apartments of about 45 m (equivalent to 14 or 15 floors). In addition, fireproofing means it can be used for openings that require fireproof equipment to be installed due to the risk of a fire spreading. It also works as an effective way to prevent condensation on aluminum sashes.
