Glazing and Energy Efficiency This Winter

June 20, 2017

Did you know that windows are one of the most interesting parts of your home? They let in air and light, they let you look out and they connect the inside and the outside of your home. While they do this, they also, unfortunately, let in heat during the summer and let heat out during the winter. Energy efficient windows will make your home more comfortable and reduce your energy costs which lead to a cleaner, healthier and brighter environment. Windows impact the heating and cooling loads of your home with up to 40% of the home heating loss during winter and up to 87% of its heat gained through windows in the summer. Improving your homes thermal performance reduces greenhouse gas emissions and reduces energy costs.

Glazing and Energy Efficiency This Winter

The actual impact glazing and thermal performance have in your home is dependent on –

The building materials – the mass and the insulation
The climate you live in – temperature, humidity, sunshine and wind
The thermal properties of the window glazing
Building design – the form and layout of your home
The size of the windows, their location, and the amount of shading

The most cost-effective way of achieving a good thermal presence is by incorporating passive solar principles into your home at the design stage. Some simple principles that can be incorporated include –

Placing seals on openings to stop unwanted draughts
Locate the size and the windows based on shading – to let the sun in when it’s needed (winter) and keep it out when it’s not wanted (summer)
Place window and door openings to allow natural cooling through cross ventilation

When it comes to thermal comfort the choice of glazing improves this, especially on large windows. Comfort isn’t defined just by air temperature; the temperature of surrounding surfaces has an impact as well. It is important to choose the right window – windows add to the energy performance of your home through conductive and solar heat gain. There are literally thousands of types of glass and frames to choose from, so selecting the right one is critical for improving the energy efficiency of your home. Products have been designed to keep heat in or out and have impacts on noise control, security, maintenance and daytime lighting. By reducing the amount of solar radiation that comes through your windows you can reduce the amount of daylight that enters your home. There are many different types of glazing available –

Toned glass – has a colouring added to it, and comes in colours such as grey, blue, green and bronze
Low emissivity glass – has either a vacuum deposited thin film metal coating or a pyrolytic coating
Laminated Glass – has a plastic glazing layer to improve impact performance
Insulated Glass – is a combination of two or more glazing layers, sealed with a gap between the layers
