Laminated glass is frequently used in locations in the house most vulnerable to injury from human effect such as bathrooms, doors, around staircases and in locations near to the flooring (it meets the requirements of 'safety glass' that is mandated for usage in these areas 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 stronger than standard glass it can resist greater impact loads before breaking. It also makes it much safer since, when it does shatter, it gets into lots of little cubic pieces rather than hazardous fragments.
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 made IGU, given that it is difficult to totally seal the border, however it can supply excellent sound control. Window movies are a thin polymer film containing an absorbing color or reflective metal layer, with an adhesive backing. They stay with your glazing to alter its colour or make it reflective.
Applied to existing glass, some window movies can halve the general SHGC of the window by absorbing and/or showing solar radiation. This can be particularly beneficial in hotter environments where cooling is the primary issue, or on east and west elevations straight exposed to long periods of sunlight. However, window movies may also reduce visible light transmittance.
For this factor, it is generally best to utilize a certified installer of window film. Frames have a considerable effect on the thermal performance of doors and windows, due to the fact that energy can be acquired and lost through the frame, as well as through the glass. Various types of frame will permit different levels of heat gain and loss, so careful option of frame is essential for efficient passive style.
However, aluminium is likewise a great conductor of heat and will reduce the insulating value of a glazing unit, unless particularly crafted to reduce this. A 'thermally broken' frame is made up of 2 aluminium areas connected by a structural insulator (normally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and lowers the heat flowing through the frame.
Lumber frames are an excellent natural insulator that can match some home designs. Lumber frames must be made from species that have naturally high toughness or be treated to avoid decay and contortion.

u, PVC windows and doors have exceptional thermal performance Photo: Ben Wrigley (Light Home Architecture and Science) Composite frames utilize aluminium profiles on the outer sections with either a lumber or u, PVC inner area. These integrate the low maintenance and resilience of aluminium with much enhanced thermal efficiency.
