Energy-efficient Windows

Save energy AND money!

You've probably heard that the amount of CO2 that you produce in your day-to-day life is directly linked to climate change. The fuel that you use to heat your home is likely to generate CO2.  By becoming more energy-efficient, you can help to decrease the amount of fuel needed to heat your home, which means less CO2 waste and smaller monthly bills.  One way of making your home more energy-efficient is to install energy-saving windows.

Energy-saving windows make your home more energy-efficient

You may be shocked to know that up to 25% of the heat in your home can be lost through your windows.   By installing energy-saving windows containing Pilkington energiKare™, you can reduce the amount of energy lost through your windows by up to 75%!

Energy-efficient windows save you money

Energy-efficient windows help to reduce the amount of energy needed to maintain an ambient temperature in your home, which subsequently reduces your monthly bills.  By choosing Pilkington energiKare™ insulating glass units, you can reduce your heating bills by up to 20% every year.  A typical semi-detached house can save up to £7000 over the lifetime of the windows.

Energy-saving windows make your home more environmentally friendly

By installing energy-efficient windows containing Pilkington energiKare™, you can take satisfaction in the fact that you will be doing your bit for the planet!  Pilkington energiKare™ insulating glass units will reduce your home’s CO2 output, making your carbon footprint smaller.  In a gas-heated semi-detached house, you could save 0.72 Tonnes of CO2 per year by switching from single glazing in timber to Pilkington energiKare™ in a PVCu frame.
