Energy saving blinds and automated external shading can influence how much solar heat enters through windows. Depending on glazing, orientation, control strategy and season, sun shading solutions can help reduce cooling demand and support thermal comfort.
A study by the Industrial Association of Roller Shutter Sun Shading Automation (IVRSA) confirms that, depending on the building, the correct combination of windows and automated sun shading can save up to 70% of cooling energy and up to 30% of heating energy compared to windows without sun shading systems.
The cited study indicates that automated external shading can contribute to lower heating and cooling energy demand, depending on the building and control strategy. Modelled savings vary with glazing, facade orientation, climate and operation.
For us, CO 2 reductions and sustainability are part of the high quality and longevity of our products. This is highlighted by our services , such as the 5-year manufacturer's warranty or the 10-year protection package for our outdoor living products. Curtain replacements or repairs instead of buying again - the serviceability of our products speaks for itself and thus also protects both the environment and your wallet.
Buildings are not yet sufficiently geared towards the advancing climate change - neither in external shading for home renovation nor in blinds for new build Therefore, these buildings increasingly threaten to overheat in summer. Current forecasts show that the number of days on which the thermometer exceeds 30 degrees will increase. The use of air conditioning systems seems like an obvious solution, but would lead to a massive increase in energy consumption.
A new study by the engineering firm Hauser (IBH) on behalf of the Repräsentanz Transparente Gebäudehülle (Transparent Building Envelope Representative Office) shows that various sun shading measures are an effective means of preventing overheating and can minimise or, in many cases, completely prevent energy consumption for air conditioning.

Clear facts are needed about the climate transition in the construction sector. This applies to planners, project managers and property developers. For this reason, WAREMA has analysed the CO 2 footprint of its three best-selling products - the so-called Product Carbon Footprint (PCF) .
The result clearly shows that an external sun shading system can save up to 28 times more CO 2 in its use phase than is produced during its entire life cycle, from raw material procurement, production and logistics through to use and disposal.
With an external venetian blind from WAREMA, for example, you save 5.8 tons of CO 2 over the entire service life of the product. It's a true "climate protection system".
We have a clear goal: we want to reduce CO 2 emissions from our products by a further 30% by 2030.
That's why we do the research: we have calculated the CO 2 footprints of our most popular products. The results clearly show that an external sun shading system can save up to 28 times more CO 2 in its use phase than is produced during its entire life cycle, from raw material procurement, production and logistics through to use and disposal.
But that's not enough for us: using this information, we have set ourselves the clear goal of reducing the CO 2 emissions of our products by a further 30% by 2030. We therefore continuously review the raw materials we use and try to exploit existing potential. As a first step, we have already successfully achieved savings with CO2-reduced aluminum.
We are certified.
A key requirement for WAREMA is ensuring and continuously improving the high quality standards of our products, services, occupational safety and environmental protection through a comprehensive management concept.
The management system covers product and service quality, occupational safety and environmental protection. Product performance and service life depend on the selected system, installation, operation and maintenance.
We are on the way together.
As well as measuring our product carbon footprints (PCFs), we have also drawn up environmental product declarations (EPDs) in collaboration with the German Association of the Roller Shutter, Sun Shading and Automation Industry (IVRSA e.V.) and the German Institute for Construction and the Environment (IBU e.V.) to provide detailed information about the environmental impacts of our external venetian blinds, roller shutters and window awnings.
We are the first member from the sun shading sector.
A|U|F e.V. is an association that maintains a closed material cycle for aluminium in the window, door and facade sectors. The goal: The environmentally friendly and resource-conserving reuse and recycling of aluminium.
Scrap from production and dismantled components are collected, shredded, sorted and cast into new extrusion billets for aluminium profiles by certified environmental partners at the end of the usage phase. WAREMA became the first member company in the sun shading sector in February 2024.
Doing business sustainably is an all-embracing subject that nowadays applies not only to production processes. As well as manufacturing high-grade products with a long life that improve the energy footprint of buildings, WAREMA has also been working for years to expand its comprehensive range of services and to continuously improve its own environmental management and efficiency.
To us, sustainability means holistic responsibility – and is deeply rooted in the WAREMA Group's DNA. Sustainability is not new for us. For many years, people, cooperation, and the protection of the environment have been at the heart of our work. We are already on our way to achieving this using of a range of measures.
WAREMA stands for quality. It is the starting point for our sustainability initiatives and the key idea behind them. This is because the longer a product is used for, the more sustainable it is, as it allows valuable resources to be saved and waste to be avoided. WAREMA uses high-grade raw materials from certified suppliers and applies defined social standards in its supply chains. WAREMA Life Cycle Service supports maintenance, repair and continued product use. A network of service partners, spare parts and services such as fabric replacement can support repair and continued use of WAREMA sun shading products.
The times when the value chain ended with the delivery of the product are long past. Reliable, comprehensive services are of crucial importance. They not only make a key contribution to a high level of customer satisfaction, but also meet the requirements for increased sustainability by allowing the products to be used for longer. For example, with our outstanding service , we help our partners to provide all-inclusive service packages. We were awarded the "Service Champion 2022" seal of quality for our high quality standards and our exceptional performance in the area of service and support.
WAREMA offers a 5-year manufacturer warranty for eligible outdoor living products. The applicable scope, services and conditions are defined in the current warranty terms.
For eligible products, the WAREMA 10-year protection package can extend cover and include defined service and maintenance benefits. The applicable scope and conditions depend on the current package terms.
As long ago as 2002, WAREMA introduced a certified environmental management system which was re-certified in 2006, 2015 and 2021 according to ECOPROFIT criteria. ECOPROFIT stands for "Ecological Project for Integrated Environmental Technology". The project is a cooperation between administrative districts and companies at the local level. Its goal is to reduce the operating costs incurred by businesses and conserve natural resources.
