Laminated glass is typically used in locations in the house most prone to injury from human impact such as bathrooms, doors, around staircases and in locations close to the flooring (it satisfies the requirements of 'shatterproof glass' that is mandated for usage in these locations by Australian Basic AS 1288 Glass in buildings).
Toughened glass has been 'tempered' by being reheated and quickly cooled again. This process makes it much more powerful than standard glass it can resist greater effect loads before breaking. It also makes it much safer because, when it does shatter, it gets into numerous little cubic pieces rather than unsafe fragments.
Toughened glass has no thermal or acoustic benefits 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 made IGU, given that it is difficult to completely seal the boundary, but it can provide good noise control. Window films are a thin polymer movie containing a soaking up color or reflective metal layer, with an adhesive backing. They adhere to your glazing to alter its colour or make it reflective.
Applied to existing glass, some window films can halve the general SHGC of the window by soaking up and/or reflecting solar radiation. This can be particularly advantageous in hotter climates where cooling is the primary concern, or on east and west elevations directly exposed to extended periods of sunlight. However, window films might likewise lower visible light transmittance.
For this factor, it is normally best to use a recognized installer of window movie. Frames have a significant influence on the thermal performance of doors and windows, since energy can be gotten and lost through the frame, as well as through the glass. Different types of frame will enable various levels of heat gain and loss, so careful option of frame is important for efficient passive design.
However, aluminium is also a very good conductor of heat and will decrease the insulating value of a glazing system, unless particularly engineered to minimize this. A 'thermally broken' frame is comprised of 2 aluminium sections connected by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and lowers the heat streaming through the frame.
Lumber frames are a good natural insulator that can match some home designs. Lumber frames need to be made from species that have naturally high resilience or be treated to prevent decay and deformation.

u, PVC doors and windows have exceptional thermal performance Photo: Ben Wrigley (Light House Architecture and Science) Composite frames use aluminium profiles on the external areas with either a wood or u, PVC inner area. These integrate the low upkeep and durability of aluminium with much enhanced thermal performance.
