Laminated glass is frequently used in areas in the home most susceptible to injury from human effect such as restrooms, doors, around staircases and in areas near the flooring (it satisfies the requirements of 'shatterproof 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 resist greater effect loads prior to breaking. It likewise makes it safer since, when it does shatter, it burglarizes numerous little cubic pieces instead of hazardous shards.
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 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 manufactured IGU, given that it is difficult to totally seal the boundary, but it can provide good noise control. Window movies are a thin polymer movie consisting of a taking in dye or reflective metal layer, with an adhesive backing. They stick to your glazing to alter its colour or make it reflective.
Applied to existing glass, some window films can cut in half the total SHGC of the window by taking in and/or showing solar radiation. This can be especially useful in hotter climates where cooling is the main issue, or on east and west elevations directly exposed to extended periods of sunlight. Window movies might also minimize visible light transmittance.
For this factor, it is usually best to use a certified installer of window film. Frames have a significant effect on the thermal performance of windows and doors, because energy can be gained and lost through the frame, in addition to through the glass. Different kinds of frame will permit different levels of heat gain and loss, so cautious option of frame is necessary for reliable passive style.
Aluminium is also an extremely great conductor of heat and will reduce the insulating value of a glazing system, unless specifically engineered to reduce 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 flowing through the frame.
Lumber frames are a good natural insulator that can fit some house designs. Timber frames need to be made from species that have naturally high toughness or be dealt with to avoid decay and contortion.

u, PVC doors and windows have excellent thermal performance Photo: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the external sections with either a timber or u, PVC inner area. These integrate the low maintenance and toughness of aluminium with much enhanced thermal performance.
