All windows provide a certain degree of noise control but where noise is a particular problem choosing the right glass is critical in providing a solution to the problem. Several options can be chosen - high performance acoustic laminates, laminated glass, a thicker float glass or glass insulating units with a combination of these glasses.
Low Emissivity Glass
Emissivity is the rate heat is radiated through an item. Low emissive glasses have been developed to provide increased thermal insulation This has a coating on the surface that faces into the air gap of double glazed units. The microscopic coating of the pane of glass makes a difference to its performance by inhibiting the radiation of heat from within a room and instead the heat is reflected back into the room by the coating.
Heat losses can be compared by their U values. The higher the U value the greater the heat loss. Ordinary glass has a U value of 2.8 and double glazing with Pilkington K as used by ourselves has a U value of only 1.9 which is considerably better than conventional double glazing. Low emissivity glass such as Pilkington K have been designed for use in double glazed units only.
