Laminated glass is often used in areas in the home most vulnerable to injury from human impact such as restrooms, doors, around staircases and in areas near to the floor (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 rapidly cooled once again. This process makes it much more powerful than standard glass it can withstand higher impact loads before breaking. It also makes it more secure due to the fact that, when it does shatter, it gets into numerous small cubic pieces rather than unsafe shards.
Toughened glass has no thermal or acoustic benefits 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 connected 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 manufactured IGU, since it is difficult to absolutely seal the boundary, but it can supply good sound control. Window films are a thin polymer movie including an absorbing dye or reflective metal layer, with an adhesive support. They adhere to your glazing to alter its colour or make it reflective.
Applied to existing glass, some window movies can cut in half the total SHGC of the window by soaking up and/or reflecting solar radiation. This can be especially advantageous in hotter climates where cooling is the primary issue, or on east and west elevations directly exposed to extended periods of sunshine. Window films may also decrease noticeable light transmittance.
For this reason, it is typically best to use a certified installer of window movie. Frames have a substantial effect on the thermal performance of doors and windows, due to the fact that energy can be acquired and lost through the frame, as well as through the glass. Different kinds of frame will enable various levels of heat gain and loss, so cautious choice of frame is necessary for effective passive design.
Aluminium is also an extremely excellent conductor of heat and will reduce the insulating value of a glazing system, unless particularly crafted to reduce this. A 'thermally broken' frame is made up of 2 aluminium sections connected 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.
Timber frames are an excellent natural insulator that can suit some house designs. Lumber frames must be made from types that have naturally high resilience or be treated to avoid decay and contortion.

u, PVC doors and windows have outstanding thermal performance Picture: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the outer areas with either a timber or u, PVC inner section. These integrate the low upkeep and toughness of aluminium with much enhanced thermal performance.
