Laminated glass is frequently used in areas in the house most vulnerable to injury from human effect such as bathrooms, doors, around staircases and in locations near to the flooring (it satisfies the requirements of 'safety glass' that is mandated for usage in these locations by Australian Basic AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and quickly cooled once again. This process makes it much more powerful than standard glass it can withstand greater effect loads before breaking. It also makes it more secure due to the fact that, when it does shatter, it breaks into numerous small cubic pieces rather than dangerous shards.
Toughened glass has no thermal or acoustic advantages over other glass of the exact same toning or thickness. Secondary glazing is where single-glazed windows are retrofitted with a transparent acrylic or glass sheet attached to the inside of the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not carry out also thermally as a produced IGU, because it is impossible to totally seal the border, however it can supply great noise control. Window films are a thin polymer film including a soaking up dye or reflective metal layer, with an adhesive support. They stay with your glazing to change its colour or make it reflective.
Applied to existing glass, some window films can cut in half the overall SHGC of the window by taking in and/or reflecting solar radiation. This can be especially helpful in hotter climates where cooling is the primary issue, or on east and west elevations directly exposed to long periods of sunshine. Window films may also decrease noticeable light transmittance.
For this reason, it is typically best to utilize an accredited installer of window film. Frames have a considerable effect on the thermal efficiency of doors and windows, because energy can be acquired and lost through the frame, as well as through the glass. Various kinds of frame will permit different levels of heat gain and loss, so mindful choice of frame is very important for effective passive design.
Nevertheless, aluminium is also an extremely great conductor of heat and will decrease the insulating value of a glazing system, unless specifically crafted to minimize this. A 'thermally broken' frame is comprised of 2 aluminium sections linked by a structural insulator (typically a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and lowers the heat streaming through the frame.
They can be costly, but rates are reducing as they become more typical. Wood frames are an excellent natural insulator that can match some house styles. Lumber frames must be made from types that have naturally high resilience or be treated to avoid decay and contortion. Check that the wood is sourced from a sustainably handled forest.

u, PVC windows and doors have exceptional thermal performance Image: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the external areas with either a timber or u, PVC inner area. These integrate the low maintenance and toughness of aluminium with much improved thermal efficiency.
