BOC TARGETS THE UK DOUBLE GLAZING INDUSTRY
07 April 2003 - BOC Gases

BOC is at the forefront of the UK double glazing industry’s drive to combat global warming through the use of gases. The move is in response to new UK building regulations for the double glazing of windows, which aims to cut carbon dioxide emissions, half of which come from heating and lighting buildings.

The thermal conductivity of argon, krypton and xenon is much lower than air, leading to reduced conductive and convective heat loss. Argon and krypton mixtures are already used extensively in double glazing in North America, Scandinavia and Germany.

Mark Leonard, one of BOC’s marketing managers, said: "As the number one gases specialist in the UK BOC has the ideal supply option for any customer’s gas requirements whether it be compressed gases in cylinders or large or small quantities of liquefied gases.

"BOC is the double glazing insulating gases specialist in the UK and can provide technical support on the use and application of gases with double glazing and gas filling machines. Our team of technical support engineers offer 24 hour service and we provide a comprehensive after sales service to our customers."

The new regulations state that anyone who installs or manufacturers replacement double glazing will now have to comply with strict thermal performance standards installations or face fines of up to £5,000. The Building Regulations 2000, which were introduced in October 2001, were extended in England and Wales to cover replacement window and door installations in April 2002. These changes also cover the construction of energy-efficient building elements, such as walls, floors and roofs, and building services, such as lighting, heating and ventilation.

To comply with the regulations window manufacturers have a number of options to achieve the required U values, which are an indication of the energy efficiency of the window. The lower the U value, the less heat lost by a window of a particular size.

The options include: increasing the cavity size, using wood or uPVC frames; using triple glazing or low emissivity glass that reflects heat back into a building or filling the cavity with argon gas or an argon/krypton mix, both of which have better insulation properties than air.

The legislation was introduced by the UK government following the Kyoto world climate summit agreement, by which each of the 38 participating countries agreed to reduce their greenhouse gas emissions in 2010 by 5 per cent from 1990 levels. The drive towards energy-efficient buildings is because the energy we use to heat, light and cool buildings accounts for almost half of the UK’s total carbon dioxide emissions. one of the ‘man-made’ gases contributing to the greenhouse effect.
