Laminated glass is frequently utilized in locations in the house most vulnerable to injury from human effect such as bathrooms, doors, around staircases and in locations close to the floor (it meets the requirements of 'shatterproof 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 quickly cooled once again. This process makes it much stronger than basic glass it can withstand higher effect loads before breaking. It also makes it much safer due to the fact that, when it does shatter, it gets into numerous little cubic pieces instead of hazardous shards.
However, 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 connected to the within of the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not perform also thermally as a made IGU, since it is impossible to completely seal the perimeter, but it can offer good noise control. Window movies are a thin polymer film including a soaking up color or reflective metal layer, with an adhesive support. They stick 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 taking in and/or reflecting 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 periods of sunlight. Window movies may likewise reduce visible light transmittance.
For this factor, it is generally best to utilize an accredited installer of window movie. Frames have a considerable impact on the thermal efficiency of doors and windows, since energy can be gotten and lost through the frame, along with through the glass. Various kinds of frame will allow different levels of heat gain and loss, so careful option of frame is essential for efficient passive design.
Aluminium is also a very excellent conductor of heat and will reduce the insulating value of a glazing unit, unless specifically crafted to reduce this. A 'thermally broken' frame is comprised of 2 aluminium sections connected by a structural insulator (typically a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and reduces the heat streaming through the frame.
They can be expensive, however prices are reducing as they become more typical. Timber frames are a great natural insulator that can match some house styles. Lumber frames must be made from types that have naturally high durability or be dealt with to prevent decay and deformation. Inspect that the lumber is sourced from a sustainably managed forest.

u, PVC windows and doors have excellent thermal performance Photo: 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 integrate the low upkeep and sturdiness of aluminium with much improved thermal performance.
