Laminated glass is frequently utilized in locations in the home most susceptible to injury from human effect such as bathrooms, doors, around staircases and in areas near the flooring (it satisfies the requirements of 'shatterproof glass' that is mandated for use in these locations by Australian Standard AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and rapidly cooled again. This process makes it much stronger than standard glass it can withstand greater effect loads before breaking. It also makes it more secure since, when it does shatter, it gets into lots of small cubic pieces instead of dangerous shards.
Nevertheless, toughened glass has no thermal or acoustic advantages over other glass of the same toning or thickness. Secondary glazing is where single-glazed windows are retrofitted with a transparent acrylic or glass sheet connected to the within 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, considering that it is impossible to completely seal the perimeter, but it can offer good sound control. Window movies are a thin polymer movie including an absorbing dye or reflective metal layer, with an adhesive support. They stick to your glazing to change its colour or make it reflective.
Applied to existing glass, some window films can cut in half the general SHGC of the window by taking in and/or reflecting solar radiation. This can be especially beneficial in hotter environments where cooling is the primary issue, or on east and west elevations directly exposed to long periods of sunshine. However, window movies might also decrease noticeable light transmittance.
For this factor, it is generally best to utilize a certified installer of window movie. Frames have a considerable impact on the thermal performance of doors and windows, since energy can be gained and lost through the frame, along with through the glass. Different kinds of frame will enable different levels of heat gain and loss, so mindful option of frame is important for reliable passive style.
However, aluminium is likewise a great conductor of heat and will decrease the insulating worth of a glazing unit, unless specifically crafted to reduce this. A 'thermally broken' frame is made up of 2 aluminium sections connected by a structural insulator (usually a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and decreases the heat streaming through the frame.
Wood frames are a good natural insulator that can match some house styles. Lumber frames ought to be made from types that have naturally high durability or be treated to prevent decay and deformation.
This can result in spaces that enable air seepage unless great draught sealing (weather condition removing) is installed. u, PVC is a kind of plastic (unplasticised polyvinyl chloride, also called stiff PVC). u, PVC frames offer outstanding thermal performance, often much better than wood or thermally broken aluminium. u, PVC is long lasting and requires very little maintenance, and can be moulded into intricate profiles that offer outstanding air seals.
u, PVC windows and doors have excellent thermal efficiency Photo: Ben Wrigley (Light House Architecture and Science) Composite frames utilize aluminium profiles on the outer sections with either a wood or u, PVC inner section. These integrate the low maintenance and resilience of aluminium with much enhanced thermal performance.
