At Eco Sash & Case, we believe your home should be both stylish and sustainable. By choosing us, you’re making a smart investment in energy efficiency and eco-friendly windows that reduce your carbon footprint and enhance the comfort of your home.
How Do Energy Efficient Windows Affect the Environment?
When you upgrade to energy efficient windows, you can improve your home’s overall energy efficiency. This reduces the amount of energy your home needs to stay warm in the winter and cool in the summer. Providing a direct impact on the environment by reducing fossil fuel consumption and greenhouse gas emissions, which are the primary causes of climate change. Using less energy also means fewer harmful emissions from power stations and a lower demand on non-renewable resources. That is not only good for the planet but also saves you money on your utility bills.
Are Double-Glazed Windows Good for the Environment?
Double-glazed units have two panes of glass separated by a layer of air or inert gas, which acts as insulation. This design reduces heat transfer. Preventing warmth from escaping during cold months and keeping unwanted heat out during the summer. The thermal effectiveness of double-glazing is often measured by its U-value. The lower the U- values the better thermal performance. Not only does this help reduce your reliance on heating and cooling systems, but it also lowers your carbon emissions by minimizing heat loss. At Eco Sash & Case, we specialize in retrofitting traditional sash windows with energy efficient glazing. This helps maintain their historic appearance while bringing them up to modern standards of thermal efficiency. If your windows aren’t able to be upgraded because of their condition, we are also offer a full replacement with a double-glazed unit.
What Is the Most Environmentally Friendly Wood?
Timber is a core component of our windows. The most environmentally friendly wood comes from sustainably managed forests that are certified by the FSC (Forest Stewardship Council) or PEFC (Program for the Endorsement of Forest Certification). These certifications guarantee that the wood is harvested in a way that protects biodiversity, prevents deforestation, and ensures fair working conditions. At Eco Sash & Case, we also ensure that the wood we use is FSC and PEFC certified, contributing to sustainable forestry practices.
Our promise
We stand by our values with the Eco Sash & Case Promise. That means we promise to give you an honest opinion about the condition of your windows and only recommending replacement when absolutely necessary. We conduct a comprehensive inspection for rot or structural damage before we begin any work. Our approach prioritizes restoration over replacement, which preserves the original character of your home and reduces environmental waste.
Our Use of Eco-Friendly Materials
As part of our commitment to sustainability, we only use eco-friendly materials in our window. Our paints are low-VOC or zero-VOC, meaning they emit fewer harmful chemicals into your home and the environment. Our sash ropes are made from 100% natural organic cotton and are completely plastic-free, yet remain strong and durable. Our glues and fillers are all environmentally safe, ensuring that our repairs are as kind to the planet.
Responsible Waste Recycling
We also take waste management seriously. During our renovation work, we separate recyclable and non-recyclable waste on-site. Glass, wood, and metal fixtures are all recycled wherever possible. Our team uses green bags for recyclable waste and black bags for general waste, making sure nothing ends up in the landfill unnecessarily. Responsible recycling is just one more way we lower the carbon footprint of every project we complete. We also ensure that all our practices comply with current building regulations and contribute to improved energy performance of the properties we work on.
How We Offset Our Carbon Footprint
To go a step further, we offset our carbon footprint by planting a Scots Pine for every completed sash window project. We do this through Trees for Life, an award-winning Scottish charity working to restore the Caledonian Forest in the Scottish Highlands. This forest is a vital ecosystem that provides a home for rare wildlife and helps combat climate change.
A single Scots Pine can absorb up to 22 kg of CO₂ per year and sequester up to 1 ton of CO₂ over its lifetime. It’s our way of giving back to the environment while making your home more sustainable.
