Laminated glass is frequently utilized in locations in the house most prone to injury from human effect such as bathrooms, doors, around staircases and in areas near to the flooring (it satisfies the requirements of 'safety glass' that is mandated for use in these locations by Australian Standard AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and quickly cooled once again. This procedure makes it much stronger than standard glass it can withstand higher impact loads prior to breaking. It also makes it safer because, when it does shatter, it gets into many small cubic pieces rather than hazardous fragments.
Toughened glass has no thermal or acoustic advantages over other glass of the very same toning or thickness. Secondary glazing is where single-glazed windows are retrofitted with a transparent acrylic or glass sheet attached to the inside of the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not carry out as well thermally as a made IGU, given that it is difficult to totally seal the perimeter, however it can supply great noise control. Window films are a thin polymer film including a soaking up dye or reflective metal layer, with an adhesive support. They stay with 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 taking in and/or showing solar radiation. This can be particularly advantageous in hotter climates where cooling is the main issue, or on east and west elevations directly exposed to long durations of sunlight. However, window films may also reduce visible light transmittance.
For this reason, it is typically best to use an accredited installer of window film. Frames have a considerable influence on the thermal performance of doors and windows, due to the fact that energy can be gained and lost through the frame, as well as through the glass. Various kinds of frame will enable various levels of heat gain and loss, so careful choice of frame is essential for effective passive style.
Aluminium is likewise a really great conductor of heat and will reduce the insulating value of a glazing system, unless specifically engineered to decrease 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 decreases the heat streaming through the frame.
Wood frames are an excellent natural insulator that can suit some home designs. Timber frames should be made from types that have naturally high sturdiness or be dealt with to prevent decay and contortion.

u, PVC windows and doors have outstanding thermal performance Image: Ben Wrigley (Light Home Architecture and Science) Composite frames utilize 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 performance.
