Laminated glass is often utilized in locations in the home most vulnerable to injury from human impact such as bathrooms, doors, around staircases and in areas near to the floor (it fulfills the requirements of 'shatterproof glass' that is mandated for usage in these areas by Australian Standard AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and quickly cooled once again. This process makes it much stronger than standard glass it can withstand greater impact loads before breaking. It also makes it much safer since, when it does shatter, it burglarizes lots of small cubic pieces instead of unsafe fragments.
Toughened glass has no thermal or acoustic benefits over other glass of the very same toning or density. Secondary glazing is where single-glazed windows are retrofitted with a transparent acrylic or glass sheet attached to the within the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not perform too thermally as a made IGU, considering that it is difficult to completely seal the border, but it can provide great noise control. Window films are a thin polymer film containing an absorbing dye or reflective metal layer, with an adhesive support. They stick to your glazing to alter its colour or make it reflective.
Applied to existing glass, some window movies can cut in half the general SHGC of the window by soaking up and/or reflecting 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 periods of sunshine. Nevertheless, window movies may also minimize visible light transmittance.
For this factor, it is typically best to utilize a recognized installer of window film. Frames have a substantial influence on the thermal efficiency of windows and doors, due to the fact that energy can be gotten and lost through the frame, as well as through the glass. Different kinds of frame will permit various levels of heat gain and loss, so cautious choice of frame is important for reliable passive design.
Aluminium is also an extremely excellent conductor of heat and will decrease the insulating worth of a glazing unit, unless specifically crafted to decrease this. A 'thermally broken' frame is comprised of 2 aluminium sections linked by a structural insulator (normally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and minimizes the heat streaming through the frame.
Lumber frames are an excellent natural insulator that can suit some house designs. Lumber frames should be made from species that have naturally high resilience or be dealt with to prevent decay and deformation.

u, PVC windows and doors have excellent thermal performance Image: Ben Wrigley (Light Home Architecture and Science) Composite frames utilize aluminium profiles on the external sections with either a wood or u, PVC inner area. These integrate the low maintenance and resilience of aluminium with much improved thermal performance.
