With today’s global awareness of climate change, many people are looking for new ways to reduce energy and carbon emissions. That’s why Senator Windows, having led the way in energy-efficient windows and doors for 30 years, is proud to launch the new Senergy+ range of products. Made exclusively from lead-free PVC material, these new energy efficient windows actually exceed the energy standards set down by the National Standards Authority of Ireland (NSAI) new Window Energy Performance (WEP) initiative. This means the Senergy+ window range will not only reduce your heating costs but will also help to reduce your carbon footprint, enabling us all to live in a greener environment. We have showrooms in Dublin, Cork, Limerick, Mayo, Clare, Cavan, Kildare, Kilkenny, Tipperary, Kerry, Wexford, Meath, Dundalk and Galway where you can view our wide range of energy efficient windows and doors; call any of these showrooms to make an appointment today to discuss your needs for high quality, energy efficient windows and doors.
We appreciate that it can be difficult to understand the industry jargon, so we have produced this information to help you understand more about Window Energy Ratings, current industry standards and why you should choose the new Senergy+ Windows.
What are Energy Efficient Windows?
They are windows that help to contain and conserve heat within the home by keeping out wind and rain and resisting condensation, while at the same time allowing natural ‘free’ energy – the warmth of the sun – to heat the home.
What is a Window Energy Rating?
Window Energy Ratings use a consumer-friendly traffic-light-style A-E ratings guide, similar to that used on ‘white’ goods such as fridges, freezers and washing machines. This ratings label can be used by you to make more informed choices about the energy efficiency of the windows you are buying.
So how do you know if a window is Energy Efficient?
Energy Rated Windows are easy to recognise – just look for the labels! If the window does not have a BFRC (British Fenestration Rating Council) or NSAI energy-rated certificate, it’s not a registered Energy Efficient Window. NSAI’s Window Energy Performance (WEP) Certificate displays an overall energy rating (similar to the Building Energy Rating BER label) for a defined window and window-frame assembly that helps consumers to make an informed selection. The scheme is applicable to window manufacturers and companies marketing imported windows for domestic buildings. The purpose of the scheme is to independently certify windows for an energy performance (WEP) rating.
How are windows rated?
Each window rated by NSAI or BFRC has a unique label. This label will display the following information:
- rating level – A, B, C, etc.
- window U-value (thermal transmittance), e.g. 1.4 W/(m2.K)
- effective heat loss due to air penetration (air leakage) as L, e.g. 0.01 W/(m2.K)
- solar heat gain (solar factor), e.g. g = 0.43
Simply put, this will determine how well a product will perform the functions of:
- helping you contain and conserve heat within your building in the winter
- keeping out the wind
