Laminated glass is frequently used in locations in the home most susceptible to injury from human impact such as restrooms, doors, around staircases and in locations near to the floor (it satisfies the requirements of 'shatterproof glass' that is mandated for use in these locations by Australian Basic AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and rapidly cooled again. This process makes it much more powerful than basic glass it can withstand higher effect loads before breaking. It also makes it more secure because, when it does shatter, it breaks into lots of small cubic pieces instead of harmful fragments.
Toughened glass has no thermal or acoustic benefits over other glass of the exact same toning or thickness. Secondary glazing is where single-glazed windows are retrofitted with a transparent acrylic or glass sheet connected to the within the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not perform also thermally as a produced IGU, since it is impossible to absolutely seal the border, but it can provide good sound control. Window movies are a thin polymer film including an absorbing 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 overall SHGC of the window by soaking up and/or showing solar radiation. This can be especially beneficial in hotter environments where cooling is the main concern, or on east and west elevations directly exposed to long durations of sunlight. Window films might likewise decrease noticeable light transmittance.
For this reason, it is typically best to utilize a recognized installer of window film. Frames have a substantial effect on the thermal performance of doors and windows, since energy can be acquired and lost through the frame, along with through the glass. Various kinds of frame will enable various levels of heat gain and loss, so careful choice of frame is very important for reliable passive design.
However, aluminium is likewise an excellent conductor of heat and will decrease the insulating value of a glazing system, unless particularly crafted to lower this. A 'thermally broken' frame is made up of 2 aluminium areas connected by a structural insulator (typically a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and lowers the heat flowing through the frame.
Timber frames are an excellent natural insulator that can suit some house styles. Lumber frames ought to be made from types that have naturally high toughness or be dealt with to prevent decay and contortion.

u, PVC doors and windows have excellent thermal efficiency Photo: Ben Wrigley (Light Home Architecture and Science) Composite frames utilize aluminium profiles on the external areas with either a lumber or u, PVC inner section. These combine the low upkeep and resilience of aluminium with much enhanced thermal performance.
