Laminated glass is typically utilized in locations in the home most vulnerable to injury from human impact such as restrooms, doors, around staircases and in locations near to the floor (it fulfills the requirements of 'security glass' that is mandated for usage in these locations by Australian Standard AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and quickly cooled again. This process makes it much more powerful than basic glass it can resist greater impact loads prior to breaking. It also makes it safer because, when it does shatter, it breaks into lots of small cubic pieces rather than dangerous shards.
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 connected to the within 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, because it is difficult to totally seal the boundary, but it can provide great sound control. Window films are a thin polymer film containing a soaking up color or reflective metal layer, with an adhesive backing. They adhere to your glazing to change 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 reflecting solar radiation. This can be especially helpful in hotter environments where cooling is the main issue, or on east and west elevations directly exposed to extended periods of sunlight. Window films may also lower visible light transmittance.
For this factor, it is normally best to use an accredited installer of window movie. Frames have a substantial effect on the thermal efficiency of windows and doors, since energy can be gained and lost through the frame, in addition to through the glass. Various types of frame will allow various levels of heat gain and loss, so careful choice of frame is necessary for reliable passive style.
Aluminium is likewise a really good conductor of heat and will decrease the insulating value of a glazing system, unless particularly crafted to minimize this. A 'thermally broken' frame is comprised of 2 aluminium areas linked by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and minimizes the heat flowing through the frame.
They can be costly, however costs are decreasing as they end up being more common. Wood frames are an excellent natural insulator that can match some home designs. Timber frames must be made from species that have naturally high resilience or be dealt with to prevent decay and contortion. Inspect that the lumber is sourced from a sustainably managed forest.
Nevertheless, this can result in spaces that allow air infiltration unless great draught sealing (weather stripping) is set up. u, PVC is a type of plastic (unplasticised polyvinyl chloride, also referred to as rigid PVC). u, PVC frames supply excellent thermal performance, typically better than lumber or thermally broken aluminium. u, PVC is long enduring and requires very little maintenance, and can be moulded into complicated profiles that provide exceptional air seals.
u, PVC windows and doors have outstanding thermal efficiency Photo: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the external areas with either a lumber or u, PVC inner area. These combine the low maintenance and resilience of aluminium with much enhanced thermal efficiency.
