Our double glazed windows come in a full range of styles and colour choices available to suit everyone. They are designed to offer better home's security, appearance and energy performance giving our customers peace of mind. Whether you are thinking about double glazed windows MuMullanODonnell can help. According to the British Fenestration Rating Council, an average, semi-detached house can reduce 18% of energy usage (or 0.30 tonnes) by investing in double glazed windows. Every MuMullanODonnell double glazed window is designed to fit perfectly.

Adding triple glazed windows to a property will improve its energy efficiency. McMullanODonnell's triple glazed system incorporates a twin sealed unit and our custom designed bead co-ordinates with the contours of the sculptured profile. A triple glazed standard specification window will allow you to achieve a U-value of 0.8, well ahead of the equivalent typical double glazed option of 1.4 for an A rated window. The noise reduction benefits will vary depending on glass thickness and prevailing environmental conditions.

Windows aren't just part of your home's framework. They can add light and life, warmth and beauty. By understanding the different types available and how they work, you can better match windows to your needs and your lifestyle.

By making the most of modern designs and materials, the sliding sash window can be made so that either or both sashes tilting inwards sashes have an optional 'tilt inwards' facility* incorporating stay arms for safe use. This can help with ventilation and make cleaning much easier. To produce that aesthetic Georgian appearance, Neo glazing bars can be applied to the centre of the double glazed unit or, for the most authentic appearance, glazing bars can be added to both the inside and outside of the double glazed sealed unit.
