Exciting developments in the glazing industry are combining optimum functionality, energy efficiency and impressive aesthetic qualities, to provide a perfect glazing solution.
In the majority of homes double glazing or triple glazing has replaced single glazed windows, providing a real saving grace where home insulation is needed, with features like argon gas filled glass layers, low E coatings and warm edge spacers. These modern, innovative window solutions whilst proving extremely popular within most settings have not been particularly suitable for some others such as older commercial or domestic listed buildings. While there is no question that these types of property need thermal insulation to protect from deterioration caused by damp and condensation, double glazing is sometimes not an option as it would aesthetically damage the building. The ability to preserve the look and charm of these older properties has been addressed to some extent by the installation of aluminium and secondary double glazing.
A new product from glazing manufacturers Pilkington is causing a real stir within the glazing industry as it addresses many of the issues facing designers, architects, builders and home owners. The Pilkington Spacia is high performance ultra thin, energy efficient vacuum glazing and in installation, compares very favourably to double and triple glazing. The units are just over 6mm in thickness yet can reduce noise by 31dB [triple glazing noise reduction is 27dB using three layers of 4mm glass].
Three Victorian energy efficient homes at the Building Research Establishment have been insulated by incorporating Pilkington Spacia glazing. The buildings’ original sash windows were a major source of heat loss, and the refurbishment is expected to deliver an energy saving of more than 60% with a minimum SAP rating of 80 and less than 35Kg/m2/yr of CO2 emissions.
