If you are swapping out your windows, choosing the Eco-Friendly est. the option is not only good for the planet but also for your bank balance. Inefficient windows can cost you money by wasting energy and allowing heat to escape from your home. Double and triple glazed windows provide a barrier to heat loss and reduce your energy bills. But with so many different options available, all claiming to be Eco Friendly windows, how can homeowners make the right choice?
- Energy efficiency rating of windows
To help consumers choose energy-efficient windows, the British Fenestration Rating Council across the UK has developed a system to measure the efficiency of windows. The rating system uses the letters AG, where G is the worst performing window, the window energy rating is assigned to each and every window
- The rating is calculated based on three different factors of the window:
U-value (thermal efficiency): The U-value checks the heat loss of the window and is measured by the amount of heat transferred from one side of the window to the other, the lower the U-value, the warmer the house because less heat is lost.
Solar Gain – Homeowners wish to use as a large amount of natural energy as possible from sunlight instead of paying to heat the home. How much warmth of the sun’s rays goes through the window?
- Air leak (L value): Air leak is the technical term for the draft, so the L value measures how tight the windows are. If there is any weak position around the window, you need to aspire for a 0 for L value the most energy-efficient window.
Taking these values into account, you should aim for an AC window energy class in order to optimize the energy efficiency of your home.
- Environmentally friendly materials
Not only glass should be considered as an environmentally conscious homeowner, but window frames also play an important role in the decision. Aluminum windows are likely the material of choice because they are durable, efficient, and sustainable. Since aluminum is a recyclable material, owners don’t have to worry about the environmental impact.
Wooden windows are also a great option as they use a natural material. They look great but aren’t known to offer the same durability or efficiency is PVC and aluminum. For this reason, we also offer a composite window option, for the best of both worlds. The inside of the window frame is made of sustainable wood, while on the outside a sturdy aluminum frame ensures maximum performance.
