Laminated glass is frequently used in areas in the house most prone to injury from human impact such as restrooms, doors, around staircases and in areas close to the floor (it satisfies the requirements of 'shatterproof glass' that is mandated for use in these areas by Australian Standard AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and rapidly cooled once again. This process makes it much more powerful than standard glass it can withstand higher impact loads prior to breaking. It likewise makes it safer since, when it does shatter, it breaks into lots of small cubic pieces instead of unsafe shards.
Toughened glass has no thermal or acoustic advantages over other glass of the same toning or density. 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 as well thermally as a manufactured IGU, considering that it is difficult to totally seal the perimeter, however it can supply excellent sound control. Window movies are a thin polymer movie consisting of 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 movies can halve the overall SHGC of the window by soaking up and/or reflecting solar radiation. This can be especially helpful in hotter environments where cooling is the primary issue, or on east and west elevations directly exposed to long durations of sunshine. However, window films may also lower noticeable light transmittance.
For this factor, it is generally best to use an accredited installer of window movie. Frames have a considerable impact on the thermal performance of windows and doors, due to the fact that energy can be acquired and lost through the frame, as well as through the glass. Various types of frame will permit different levels of heat gain and loss, so mindful option of frame is important for effective passive style.
Nevertheless, aluminium is also an excellent conductor of heat and will decrease the insulating value of a glazing system, unless particularly engineered to minimize this. A 'thermally broken' frame is made up of 2 aluminium areas connected by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and lowers the heat flowing through the frame.
Wood frames are a good natural insulator that can match some house styles. Lumber frames must be made from types that have naturally high sturdiness or be dealt with to avoid decay and contortion.

u, PVC doors and windows have excellent thermal performance Photo: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the external sections with either a timber or u, PVC inner area. These combine the low upkeep and toughness of aluminium with much enhanced thermal efficiency.
