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.

• Use only soft, clean cloth, free from grit or buttons with a mild soap or detergent and water or recommended glass cleaner solution.
• Make sure to dry off excess water.
• DO NOT use abrasive cleaning agents.

• Excess dirt or grit should be removed from window and door tracks, either by vacuuming or brushing out.
• Windows and Doors are designed to allow water into the sill channel, which is then drained through drain holes. The drain holes must be cleared of any obstruction.

• Remove the sliding panel of the product from the inside of the house. With the window or door partly open, lift the sliding panel up into the head while tilting the bottom of the panel towards you, out over the sill. Slide the panel downwards to remove it from the frame.
• Use a vacuum cleaner with a narrow nozzle to clean the track thoroughly.
• Use a soft rag and water mixed with mild detergent to wipe the track and rollers.
• It is important that rollers are cleaned 3-4 times a year.

• General periodic maintenance is required on all hardware supplied such as locks, hinges, catches, closers and the like.
• The external finish of hardware must be kept clean by removing any harmful residue (especially salt spray) from the surface using a non-abrasive cleaning agent.
• Internal mechanisms of locks, catches, etc should be kept in good working order by applying a light spray of lubricant (WD40, RP7 or similar).
• Care should be taken during maintenance of internal mechanisms that any finished surface (e.g. paint etc) is well protected to avoid damage.

Critical Locations for Doors

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 Mistaken for a Doorway

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:

• The daylight width is greater than 500mm
• The daylight height is greater than 1000mm
• The lowest sightline is within 500mm of the floor level
• The glazing is not opaque, patterned or leadlight
• Where a transom or hand rail is not incorporated within 700mm – 1000mm of floor level
• Where a louvre has blade widths greater than 230mm

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:

• not less than 700mm from the upper edge of the band; and
• not more than 1200mm to the lower edge of the band.

Marking is required on any glazing where all of the following applies:

• The height of the glazing is greater than 1000mm at any part; and
• The width of the glazing is greater than 500mm at any part; and
• Any part of the glazing falls within 700mm of the floor level; and
• The glazing is not provided with at least one fixed glazing bar, firmly attached to the styles to locate and protect each face of the glass. At least one glazing bar shall be located with its upper edge not less than 500mm, and its bottom edge not more than 1000mm above the floor level. The glazing bar shall have a face width not less than 40mm.

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.

• Restricted openings apply when it is possible for a person to fall from an openable window, where the distance to the nearest surface level below (eg. ground, balcony, roof, pool) is 2700mm or greater (A); and
• Where the openable portion of a window is within 865mm of the floor level (B), or the lowest climbable part of the frame falls between 150mm and 760mm of the floor level (C), or if the room is a bedroom and the opening portion of the window is within 1700mm of the floor (D), the openable portion must be restricted to facilitate a 100mm opening or be fitted with a permanent screen.
• The above rules apply to any openable window (eg. louvre, awning, double hung) of any size located on an external wall.

Note: Where the openable portion of a window is permanently fitted with a safety grill or security screen so as to prevent access to the outside or where the openable portion of a window is equal to or above 865mm from the floor level and no climbable horizontal elements (eg. transoms) exist below the openable portion within 150mm and 760mm from the floor level, no sash restriction is required.

Bushfire attack levels and corresponding sections for specific construction requirements

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.

Notes:

• This information is a guide only.
• For more specific information refer to your window or glass supplier or the WERS Website (www.wers.net)
• For window selection, Australian Building Code requirements and energy raters will specify actual U-Values and SHGCw for BCA-DTS or simulation tools such as AccuRate, FirstRate 5 or BERS Pro.

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.
