Laminated glass is frequently used in locations in the house most prone to injury from human effect such as restrooms, doors, around staircases and in areas near the floor (it meets the requirements of 'shatterproof glass' that is mandated for use in these areas by Australian Basic AS 1288 Glass in buildings).
Toughened glass has actually been 'tempered' by being reheated and quickly cooled again. This procedure makes it much more powerful than standard glass it can resist greater effect loads prior to breaking. It also makes it safer because, when it does shatter, it gets into lots of small cubic pieces instead of dangerous fragments.
Toughened glass has no thermal or acoustic advantages over other glass of the very 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 too thermally as a produced IGU, because it is impossible to completely seal the boundary, however it can offer excellent noise control. Window films are a thin polymer film 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 overall SHGC of the window by absorbing and/or reflecting solar radiation. This can be especially beneficial in hotter environments where cooling is the main issue, or on east and west elevations straight exposed to long durations of sunlight. Nevertheless, window films might also reduce visible light transmittance.
For this factor, it is normally best to use a recognized installer of window film. Frames have a considerable effect on the thermal performance of doors and windows, because energy can be acquired and lost through the frame, along with through the glass. Various kinds of frame will allow different levels of heat gain and loss, so cautious choice of frame is essential for reliable passive design.
However, aluminium is likewise an excellent conductor of heat and will reduce the insulating value of a glazing unit, unless specifically crafted to minimize 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 great natural insulator that can match some house designs. Wood frames need to be made from types that have naturally high durability or be treated to avoid decay and deformation.
(weather removing) is installed.
u, PVC doors and windows have outstanding thermal efficiency Picture: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the outer areas with either a lumber or u, PVC inner area. These combine the low maintenance and toughness of aluminium with much enhanced thermal efficiency.
