2 Upstairs windows using energy-efficient gazing. Downstairs windows using origina singe gazing. warm wecome to Pikington K Gass Therma efficiency made cear For over two decades the Pikington brand has been the driving force behind the deveopment of energy-efficient gazing. This expertise has been used to strengthen the Pikington K Gass range, which now boasts more choice than ever. So you have even more ways to achieve the Window Energy Rating (WER) you want and to compy with Part L of the Buiding Reguations, now and in the future. Don t waste energy ooking around the idea soution is right here Each product from the Pikington K Gass range usuay forms the inner pane of an Insuating Gass Unit (IGU), aso commony referred to as doube gazed unit, and has a specia ow-emissivity (ow-e) coating which is a good refector of ong wave radiation (heat). This aows ess heat to escape through windows, as it refects heat from within the room back into the buiding. t the same time, ow-e gass ets the sun s heat pass through the windows, thus aso contributing to its energy efficiency. This free heat from the sun is known as passive soar gain or g-vaue. higher g-vaue can be achieved when Pikington K Gass is combined with a ow-iron gass such as Pikington Optiwhite as the outer pane of an IGU. The Window Energy Rating (WER) is the Government-backed method of assessing and ranking the energy efficiency of a compete window. Taking into account its U-vaue, g-vaue and air infitration, the scheme aows easy comparison of the energy efficiency of competing windows on a scae of -G with being the best. The energy performance of an IGU or the window itsef can be improved in a series of steps to graduay improve the WER band achieved; firsty argon fiing improves the U-vaue, then a ow-iron gass such as Pikington Optiwhite as the outer pane improves g-vaue. The addition of a warm edge spacer bar improves the U-vaue of the whoe window. Currenty Buiding Reguations in Engand and Waes demand a minimum of band C but we expect this wi tighten with changes to Part L in 2013 and then again in Outside Shortwave radiation (eg sun) Inside Longwave radiation (eg radiators) Doube Gazed unit incorporating Pikington K Gass

3 coser ook at the range Did you know? Pikington K Gass OW can be used as the inner pane (Surface 4) of an IGU to achieve a U g -vaue as ow as 0.9 when combined with Pikington Optitherm S1 Pro T (Surface 2). Pikington K Gass The origina hard coated ow-emissivity gass, Pikington K Gass is designed to refect heat back into a buiding, greaty improving its therma efficiency and maximising the use of free heat. Pikington K Gass remains the UK s best known and most recognisabe brand name in both trade and consumer markets. Hard-coat Highy durabe Easy to hande and process Cost effective When combined with Pikington Optiwhite can easiy achieve a WER C in most frame types Readiy avaiabe from stock Doesn t have the shef ife imitations of a soft-coat product No edge deetion required Pikington K Gass OW For -rated windows with unrivaed eves of carity, Pikington K Gass OW is the cear choice. n advanced form of the origina Pikington K Gass, it aows better ight transmission, improves g-vaue and heps achieve a WER band in the greatest range of window profies when used within Pikington energikare IGUs. Hard-coat When combined with other products from our range within a Pikington energikare IGU, it s even easier to achieve a WER of Improved carity compared to standard ow-e gazing options Readiy avaiabe from stock Doesn t have the shef imitations of a soft coat product No edge deetion required Pikington K Gass OW on Surface 4 For the utimate in therma insuation Pikington K Gass OW can be used on Surface 4 (the exterior surface of the inner pane) of an IGU to provide the performance of a tripe gazed unit with doube gazing. Pikington K Gass S The atest product in our ow-e range is Pikington K Gass S, a high performance, ow-e soft-coat option, for outstanding energy-efficient gazing. Offering exceent therma insuation when incorporated within Pikington energikare IGU, Pikington K Gass S has a highy neutra appearance with optima g-vaue, therma insuation and ight transmission to provide the highest WER performance. Soft-coat The utimate high performance ow-e product highy neutra appearance with optima soar heat gain Heps windows exceed Part L reguations both now or in the future Singe Stock product

4 The benefits of using gass from the Pikington K Gass range are easy to see The Pikington brand is trusted and we recognised by consumers When combining Pikington K Gass and Pikington K Gass OW in a Pikington energikare unit you can achieve a WER band in most framing systems When Pikington K Gass S is combined with Pikington Optiwhite in a Pikington energikare IGU, -rated windows are easiy achievabe Increased ight transmission reduces the need for artificia ighting Pikington K Gass has been recognised by the Energy Saving Trust as a significant means of improving energy efficiency Pikington energikare units which hep windows to achieve WER B or above quaify for Energy Saving Recommended status Suitabe for use in PVCu, timber and auminium profies in both new and repacement windows Enabes househoders to reduce energy usage and save money on heating bis Heps Governmenta targets of reducing CO2 emissions from homes Heps to reduce window drafts, making rooms more usabe Enabes gazed areas of a buiding to be extended without increasing heat oss Reduces unsighty interna condensation Keeps conservatories more comfortabe than ordinary doube gazing Singe stocked product which is avaiabe in anneaed form and can be toughened or aminated for safety and greater security products manufactured in St Heens, Engand Note: Pikington energikare is the brand name given to doube gazed units containing any product from the Pikington K Gass Range when combined with Pikington Optiwhite (as outer pane) that wi achieve a WER of at east band C in a given window framing system.
