Laminated glass is often utilized in areas in the home most vulnerable to injury from human impact such as restrooms, doors, around staircases and in areas near the floor (it meets the requirements of 'safety glass' that is mandated for use in these areas by Australian Standard AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and rapidly cooled again. This procedure makes it much more powerful than standard glass it can resist higher impact loads before breaking. It likewise makes it safer because, when it does shatter, it gets into many small cubic pieces rather than harmful 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 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, since it is difficult to totally seal the boundary, but it can provide great sound control. Window films are a thin polymer movie 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 cut in half the overall SHGC of the window by taking in and/or showing solar radiation. This can be particularly beneficial in hotter environments where cooling is the primary concern, or on east and west elevations straight exposed to extended periods of sunlight. Window films might also decrease noticeable light transmittance.
For this reason, it is normally best to use a recognized installer of window film. Frames have a considerable influence on the thermal performance of windows and doors, since energy can be gained and lost through the frame, as well as through the glass. Different types of frame will permit different levels of heat gain and loss, so mindful option of frame is very important for efficient passive design.
However, aluminium is also a really excellent conductor of heat and will decrease the insulating value of a glazing unit, unless specifically engineered 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.
Lumber frames are a good natural insulator that can fit some home styles. Timber frames need to be made from types that have naturally high resilience or be dealt with to prevent decay and deformation.
(weather condition stripping) is installed.
u, PVC doors and windows have outstanding thermal efficiency Image: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the outer sections with either a wood or u, PVC inner section. These combine the low upkeep and durability of aluminium with much improved thermal efficiency.
