Laminated glass is frequently used in locations in the home most prone to injury from human impact such as bathrooms, doors, around staircases and in areas close to the flooring (it meets the requirements of 'security glass' that is mandated for usage in these locations by Australian Standard AS 1288 Glass in buildings).
Toughened glass has been 'tempered' by being reheated and rapidly cooled again. This process makes it much stronger than standard glass it can resist greater effect loads before breaking. It likewise makes it safer since, when it does shatter, it burglarizes numerous small cubic pieces rather than harmful fragments.
However, toughened glass has no thermal or acoustic advantages over other glass of the very same toning or thickness. Secondary glazing is where single-glazed windows are retrofitted with a transparent acrylic or glass sheet connected to the inside of the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not perform too thermally as a produced IGU, considering that it is difficult to absolutely seal the perimeter, but it can supply excellent sound control. Window movies are a thin polymer movie including an absorbing dye or reflective metal layer, with an adhesive backing. They stick to your glazing to alter its colour or make it reflective.
Applied to existing glass, some window films can cut in half the overall SHGC of the window by absorbing and/or showing solar radiation. This can be particularly advantageous in hotter climates where cooling is the primary issue, or on east and west elevations directly exposed to long durations of sunshine. Nevertheless, window movies might also decrease visible light transmittance.
For this reason, it is typically best to use a certified installer of window film. Frames have a substantial impact on the thermal performance of doors and windows, since energy can be gained and lost through the frame, in addition to through the glass. Various kinds of frame will permit different levels of heat gain and loss, so cautious option of frame is important for reliable passive design.
However, aluminium is also a great conductor of heat and will decrease the insulating worth of a glazing unit, unless particularly engineered to lower this. A 'thermally broken' frame is made up of 2 aluminium sections linked by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and decreases the heat streaming through the frame.
Lumber frames are an excellent natural insulator that can suit some house designs. Timber frames need to be made from types that have naturally high resilience or be dealt with to prevent decay and deformation.

u, PVC doors and windows have outstanding thermal performance Picture: Ben Wrigley (Light House Architecture and Science) Composite frames use aluminium profiles on the external areas with either a lumber or u, PVC inner area. These combine the low maintenance and toughness of aluminium with much enhanced thermal efficiency.
