Laminated glass is frequently used in locations in the house most prone to injury from human effect such as bathrooms, doors, around staircases and in locations near to the flooring (it meets the requirements of 'shatterproof glass' that is mandated for usage in these areas by Australian Standard AS 1288 Glass in buildings).
Toughened glass has been 'tempered' by being reheated and quickly cooled again. This procedure makes it much stronger than standard glass it can withstand greater impact loads before breaking. It likewise makes it safer due to the fact that, when it does shatter, it gets into many little cubic pieces instead of dangerous fragments.
However, 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 attached to the within the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not perform too thermally as a produced IGU, given that it is impossible to totally seal the border, however it can provide good noise control. Window films are a thin polymer movie containing a soaking up dye or reflective metal layer, with an adhesive backing. They adhere to your glazing to change 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 advantageous in hotter environments where cooling is the main issue, or on east and west elevations directly exposed to extended periods of sunlight. Window movies might also lower visible light transmittance.
For this factor, it is normally best to use an accredited installer of window movie. Frames have a substantial influence on the thermal efficiency of windows and doors, since energy can be acquired and lost through the frame, as well as through the glass. Various types of frame will enable different levels of heat gain and loss, so careful option of frame is essential for reliable passive design.
However, aluminium is also an extremely great conductor of heat and will decrease the insulating worth of a glazing unit, unless specifically engineered to reduce this. A 'thermally broken' frame is made up of 2 aluminium areas connected by a structural insulator (typically a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and minimizes the heat flowing through the frame.
Lumber frames are a good natural insulator that can fit some home styles. Lumber frames must be made from types that have naturally high toughness or be dealt with to avoid decay and deformation.
(weather stripping) is set up.
u, PVC windows and doors have outstanding thermal performance Image: Ben Wrigley (Light House Architecture and Science) Composite frames use aluminium profiles on the outer areas with either a lumber or u, PVC inner area. These integrate the low maintenance and durability of aluminium with much improved thermal efficiency.
