Drainage slots should be checked on a regular basis to ensure they have not become blocked with residual dirt or grime, to allow maximum drainage. After cleaning, a light silicon spray may be applied to the track and woolpile seals to ensure quiet and smooth operation of the locks should be checked from time to time for satisfactory operation and may require adjustment to compensate for building rollers are factory set and should not require any adjustment. If however, due to building settlement an adjustment needs to be made, the door panel must fi rst be lifted to relieve weight from the roller assembly.

For the purpose of determining the varying housing energy requirements the Building Code of Australia has divided Australia up into 8 climate zones.

8 * The SWA project has run over 4000 simulations in all 8 BCA climate zones in 3 house types with a wide range of windows to show the impact of high performance windows on the energy efficiency or star rating of the home9 Dowell Window Solutions | February 2013 Energy EfficiencyFundamentally Window energy performance is based on the following criteria: U value of the Window this figure indicates the amount of thermal transmittance through the Window based on as a rule the lower the figure the better. Solar Heat Gain Coefficient (SHGC) this figure as a % indicates the amount of solar heat that will pass through the Window on the climate zone solar heat gain can be an advantage or a rule cooling climates require low SHGC windows while heating climates may require high SHGC windows particularly on the North facing windows which provide free heating by the winter is able to produce a range of products designed to meet the increasing impact of today s environment.
