Laminated glass is often utilized in locations in the house most vulnerable to injury from human effect such as restrooms, doors, around staircases and in areas near to the floor (it meets the requirements of 'shatterproof glass' that is mandated for use in these locations by Australian Standard AS 1288 Glass in structures).
Toughened glass has actually been 'tempered' by being reheated and rapidly cooled again. This process makes it much more powerful than standard glass it can withstand greater effect loads prior to breaking. It also makes it safer due to the fact that, when it does shatter, it breaks into many small cubic pieces rather than unsafe 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 connected to the within of the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not perform too thermally as a manufactured IGU, considering that it is impossible to totally seal the border, but it can offer great noise control. Window movies are a thin polymer film containing a taking in color or reflective metal layer, with an adhesive support. They adhere to your glazing to change its colour or make it reflective.
Applied to existing glass, some window films can halve the total SHGC of the window by absorbing and/or reflecting solar radiation. This can be particularly helpful in hotter environments where cooling is the main issue, or on east and west elevations directly exposed to extended periods of sunlight. However, window films might also minimize visible light transmittance.
For this reason, it is typically best to use a certified installer of window film. Frames have a considerable effect on the thermal efficiency of windows and doors, because energy can be acquired and lost through the frame, as well as through the glass. Various types of frame will enable various levels of heat gain and loss, so cautious choice of frame is essential for effective passive style.
Aluminium is also a really good conductor of heat and will reduce the insulating value of a glazing unit, unless specifically crafted to lower this. A 'thermally broken' frame is comprised of 2 aluminium sections linked by a structural insulator (normally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and reduces the heat flowing through the frame.
They can be costly, however rates are reducing as they become more common. Wood frames are a good natural insulator that can suit some house designs. Lumber frames need to be made from types that have naturally high resilience or be dealt with to avoid decay and contortion. Check that the timber is sourced from a sustainably handled forest.
(weather condition stripping) is installed.
u, PVC doors and windows have outstanding thermal performance Image: Ben Wrigley (Light House Architecture and Science) Composite frames use aluminium profiles on the external areas with either a timber or u, PVC inner area. These integrate the low maintenance and sturdiness of aluminium with much improved thermal efficiency.
