In a rural atmosphere, cleaning may not be needed more frequently than every 6 months. In industrial and marine environments, more frequent cleaning (e.g. monthly, every 3 months is necessary). It is important that non-abrasive mild detergent solution is used for cleaning. Add the non-abrasive mild detergent solution to a bucket of warm water. Wet a clean soft, non-abrasive damp cloth then wipe the aluminium. Make sure that the surfaces are thoroughly rinsed after cleaning to remove all residues.
All glass surfaces should be kept clean by prompt removal of all dirt. Use clean water and soft clean rags as buttons or grit can scratch the glass. In some instances, a small amount of mild detergent may be of some benefit. However, DO NOT use any form of abrasive cleaner or household cleaners. When using detergent make sure that the surfaces are rinsed well after cleaning to remove any detergent residue.
The special coating on these types of glass is generally more difficult to clean.
|Type of Environment Definition of Environment||Maintenance Intervals|
|Mild||Being rural, away from the coast and remote industry and urban activity||6 months|
|Moderate||Being mainly urban, inland and away from heavy industrial activity||3 months|
|Tropical/Severe||Being coastal/marine, subject to salt deposition and within 15km of the eastern coast or 10km of the western coast of Australia||2-4 weeks|
This table represents an extract from AS1288-2006 and should be used as a guide only. Maximum areas do not take into account design wind pressures. To calculate minimum glass thickness for stress at ultimate limit state and deflection at the serviceability limit state pressures, AS1288-2006 Supplement 1 must be used. For a complete version including minimum thickness of annealed glass, refer to the published standard.
Note: AS1288-2006 states that the maximum area for 3mm annealed (float) glass is: n 0.85m2 for monolithic annealed glass or; n 1.36m2 for annealed glass incorporated in an IGU.
In the example, the product configuration on the left would be comprised of a combination of 4mm and 5mm monolithic annealed (float) glass. However, if the same opening was replaced by a single fixed lite, the minimum glass requirement is 8mm toughened glass at the very least. As a result, the product on the right would, in most circumstances, be site glazed with additional costs (i.e. crane lift, on-site labour) accounted for in the final price. Although more visually appealing, this product would be significantly more expensive due to size restrictions imposed through AS1288-2006.
Glazing in all doors (including but not limited to hinged, sliding, stacking and bi-folding) shall be Grade A safety glass in accordance with AS1288-2006 Table 5.1 and AS1288-2006 Supplement 1. Side panels next to doors are deemed to be subject to human impact where the nearest vertical sightline is less than 300mm from the nearest edge of the doorway opening and within 1200mm of the floor level and therefore glazing in this instance shall be of Grade A safety glass.
Glazing capable of being mistaken for a doorway or opening must be Grade A safety glass. By definition, glazing is considered to be capable of being mistaken for a doorway if all the following conditions are met:
Ensure that the motif has sense of permanency which includes etched or applied that are difficult to remove (kiss or security cut). They cannot be able to be pulled off easily. Standard industry practice is to have etched markings on doors leaves to ensure compliance. If the presence of glass in a door, side panel or a panel capable of being mistaken for a doorway or opening is not made apparent by transoms, colonial bars, or other components of the glazing system, or other decorative treatments, the glass shall be marked to make it visible. However, making glass visible by marking is not a substitute for safety glass where required in this standard.
Marking shall be in the form of an opaque band not less than 20mm in height and located so that the vertical distance from the floor level is:
Marking is required on any glazing where all of the following applies:
Glazing where the lowest sightline is within 500mm of the floor level shall be Grade A safety glass. Ordinary annealed (float) glass may be used providing glazing is fully framed and not less than 5mm thickness up to a maximum area of 1.2m2. Larger areas are not permitted regardless of thickness.
All glazing including mirrors within 2000mm of the floor level in wet areas shall be Grade A safety glass or Grade B safety glass in accordance with the requirements of AS1288-2006 Table 5.1.Note: Ordinary annealed glass may be used provided it is fully backed by and completely adhered to a solid material in such a way that all pieces remain bonded to the backing in the event of breakage.
Special care needs to be taken when toughened glass is to be used as a wall material or wall covering near a gas cooking appliance.
In a residential building where the distance from the nearest burner to the surface of the glass is greater than 200mm, ordinary monolithic annealed (float) glass can be used. However, where the distance is 200mm or less and greater than 140mm, a minimum 6mm toughened glass is required.
The recommended minimum clearance from the nearest burner to the surface of the glass is 140mm. Ordinary annealed (float) glass is limited to between 40°-50° where toughened float glass can be used in situations up to 250°Note: Splashbacks near a cooker require a fire retardant board behind them.
Glass within 2000mm horizontally from the bottom of the stairs and 1000mm either side of the stairs is deemed to be subject to human impact and therefore all glazing surrounding a stairway in this high risk zone shall be Grade A safety glass.
Stairways include stairwells, landings or porches where the stair flight has a minimum of two risers
The guide below outlines C-View’s direction in regards to restricted openings in all building types and exceeds requirements prescribed in the Building Code of Australia.
In today's climate where summer conditions are turning extreme, bushfires are becoming a regular occurence around Australia.
If you are contructing a house in a bushfire-prone area, you are required by new building codes to use bushfire rated building materials for construction.
To help you meet these requirements, Bradman's have devoloped FlameShield, a range of bushfire rated window and door products.
Featuring fire rated seals, toughened glass and superior air infiltration, the FlameShield window and door system complies to AS3959 standards
As a general rule, increasing mass will improve sound insulation. Brick and concrete walls have stronger sound insulating values because they are of greater mass when compared to glass. But because we need glass to see through, to provide natural daylight and to enhance a buildings look and appeal, the need for greater sound control when using glass becomes more important.
Sound reduction will improve with increased glass thickness due to the greater mass involved;
Sound reduction will decrease somewhat with increasingly larger glass areas but not enough to make much difference in the majority of architectural glass sizes;
Sound reduction will improve with the use of laminated glass due to the vibration dampening effect of the PVB interlayer.
Sound reduction will improve with the use of glass/ airspace combinations, but the performance is critically dependent upon the width of the airspace. An airspace of 100mm is generally regarded as a minimum for reasonable benefits at medium to high frequencies. The optimum airspace is about 300mm.
The RW Ratings refer to the measure of sound reduction through a wall or other building element. Since the sound reduction may be different at different frequencies, test measurements are subjected to a standard procedure which yields a single number that is about equal to the average sound reduction in the middle of the human hearing range.
Choosing energy efficient windows will make your home more comfortable, dramatically reduce your energy costs and help to create a brighter, cleaner and healthier environment. Windows are possibly the most complex and interesting elements in the fabric of our homes. They provide light and fresh air and offer views that connect our interior living spaces with the great outdoors.
However, windows can represent a major source of unwanted heat gain in summer and significant heat loss in winter. Windows can severely impact the heating and cooling loads of a building. Between 46%-61% of a home’s heating energy can be lost and between 79%-86% of its heat gained through windows. Improving their thermal performance increases comfort and reduces energy costs and Australia’s greenhouse gas emissions.

|Considerations||Keep solar radiation out of the home Retain coolness of air-conditioned air|
|Other Factors||Windows with high operable areas to maximise opportunity for air movement for natural cooling|
|Star Impact||SHGCw optimised (tinted) - has the potential to improve up to approximately 1 star. U-Value - has the potential to improve up to approximately 0.25 stars for each unit reduction in U-Value. Ventilation - has the potential to improve up to approximately 0.25 stars per additional 20% of openable area.|
|Heating/Cooling Impact||Each star corresponds to reduction in Heating/Cooling requirements of 15% to 30% on pre improved level. Star uplift due to reducing SHGC reduces cooling load but may marginally increase heating load in cooler months.|
|Cost and Green House Gases (GHG) Savings||Approximately 3,000MJ of energy saved per star, mostly cooling - worth about $150-$250 and up to 0.35t of GHG. (Based on Brisbane, 240m house)|
Everything in the 'building envelope' contributes to the overall energy rating. The most important factor is adequate insulation - but windows and doors are also important.
The star system used for window and door performance is to show relative performance, the same way fridged do. A 6 star house need to achieve a specific rating based on its location, and that rating is for the performance of the whole building - with each separate part doing its job.
