For applications requiring an optimised Ug value we introduce a new concept for the ultimate in thermal efficiency. By combining Pilkington K Glass™ OW on Surface 4* of an IGU with Pilkington Optitherm™ S1 Plus ultra low-emissivity glass on Surface 2** a very low Ug-value of 0.9 W/m²K can be achieved. Put simply you get triple performance with only two panes of glass! Pilkington K Glass™ OW has always been the ideal choice for clarity. As an advanced form of the original Pilkington K Glass™ it provides better light transmission and allows in more free heat from the sun to enable householders to reduce energy usage and save money on heating bills.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Pilkington is consulted before specifying.
