Laminated glass is frequently used in locations in the home most vulnerable to injury from human impact such as restrooms, doors, around staircases and in areas close to the floor (it satisfies the requirements of 'safety glass' that is mandated for usage in these locations by Australian Standard AS 1288 Glass in buildings).
Toughened glass has been 'tempered' by being reheated and rapidly cooled again. This process makes it much stronger than standard glass it can withstand greater impact loads before breaking. It also makes it much safer due to the fact that, when it does shatter, it gets into lots of small cubic pieces instead of hazardous fragments.
Toughened glass has no thermal or acoustic benefits over other glass of the same toning or density. Secondary glazing is where single-glazed windows are retrofitted with a transparent acrylic or glass sheet attached to the within the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not carry out too thermally as a manufactured IGU, given that it is impossible to completely seal the border, but it can supply great noise control. Window films are a thin polymer film containing an absorbing color or reflective metal layer, with an adhesive support. They stay with your glazing to alter its colour or make it reflective.
Applied to existing glass, some window movies can cut in half the general SHGC of the window by soaking up and/or showing solar radiation. This can be especially helpful in hotter climates where cooling is the primary concern, or on east and west elevations directly exposed to long periods of sunlight. However, window movies might also minimize noticeable light transmittance.
For this reason, it is typically best to utilize a certified installer of window movie. Frames have a significant impact on the thermal performance of windows and doors, due to the fact that energy can be gained and lost through the frame, in addition to through the glass. Various kinds of frame will allow different levels of heat gain and loss, so mindful choice of frame is essential for effective passive design.
Aluminium is also a really good conductor of heat and will decrease the insulating worth of a glazing unit, unless specifically engineered to reduce this. A 'thermally broken' frame is made up of 2 aluminium areas linked by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and reduces the heat streaming through the frame.
Lumber frames are an excellent natural insulator that can suit some house designs. Lumber frames should be made from types that have naturally high durability or be treated to prevent decay and deformation.
This can result in spaces that allow air infiltration unless excellent draught sealing (weather condition stripping) is installed. u, PVC is a form of plastic (unplasticised polyvinyl chloride, likewise understood as rigid PVC). u, PVC frames offer outstanding thermal performance, frequently much better than wood or thermally damaged aluminium. u, PVC is long enduring and needs very little upkeep, and can be moulded into intricate profiles that supply exceptional air seals.
u, PVC doors and windows have excellent thermal performance Picture: Ben Wrigley (Light House Architecture and Science) Composite frames utilize aluminium profiles on the outer sections with either a wood or u, PVC inner area. These integrate the low maintenance and resilience of aluminium with much enhanced thermal performance.
