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 locations near to the flooring (it satisfies the requirements of 'shatterproof glass' that is mandated for use in these areas by Australian Basic AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and rapidly cooled once again. This procedure makes it much more powerful than standard glass it can withstand higher impact loads before breaking. It also makes it much safer since, when it does shatter, it gets into lots of small cubic pieces rather than dangerous shards.
Toughened glass has no thermal or acoustic benefits 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 attached to the within the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not carry out as well thermally as a produced IGU, given that it is difficult to absolutely seal the border, however it can supply great sound control. Window films are a thin polymer film consisting of a soaking up color or reflective metal layer, with an adhesive backing. 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 particularly helpful in hotter climates where cooling is the main concern, or on east and west elevations directly exposed to long periods of sunlight. Window movies might likewise decrease visible light transmittance.
For this factor, it is generally best to utilize an accredited installer of window film. Frames have a considerable influence on the thermal performance of windows and doors, since energy can be gained and lost through the frame, in addition to through the glass. Various kinds of frame will enable different levels of heat gain and loss, so mindful choice of frame is very important for efficient passive design.
Aluminium is likewise an extremely great conductor of heat and will reduce the insulating value of a glazing system, unless particularly crafted to lower this. A 'thermally broken' frame is made up of 2 aluminium sections connected by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and minimizes the heat flowing through the frame.
They can be costly, but prices are decreasing as they become more common. Lumber frames are a good natural insulator that can match some home designs. Timber frames should be made from species that have naturally high resilience or be treated to avoid decay and contortion. Check that the wood is sourced from a sustainably managed forest.

u, PVC doors and windows have outstanding thermal efficiency Image: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the outer sections with either a timber or u, PVC inner area. These combine the low upkeep and resilience of aluminium with much improved thermal efficiency.
