Laminated glass is often utilized in areas in the house most vulnerable to injury from human impact such as bathrooms, doors, around staircases and in locations near to the floor (it fulfills the requirements of 'shatterproof 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 quickly cooled once again. This procedure makes it much more powerful than standard glass it can resist greater effect loads prior to breaking. It also makes it more secure because, when it does shatter, it gets into many little cubic pieces instead of hazardous shards.
However, 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 attached 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 manufactured IGU, given that it is difficult to completely seal the border, but it can offer excellent 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 movies can cut in half the overall SHGC of the window by soaking up and/or reflecting solar radiation. This can be especially advantageous in hotter environments where cooling is the main issue, or on east and west elevations directly exposed to extended periods of sunshine. However, window movies might likewise lower noticeable light transmittance.
For this reason, it is generally best to use a recognized installer of window movie. Frames have a significant impact on the thermal performance of windows and doors, because energy can be acquired and lost through the frame, as well as through the glass. Various types of frame will permit different levels of heat gain and loss, so cautious option of frame is very important for effective passive design.
Aluminium is also a very good conductor of heat and will reduce the insulating worth of a glazing system, unless specifically crafted to lower this. A 'thermally broken' frame is comprised of 2 aluminium areas linked by a structural insulator (normally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and reduces the heat flowing through the frame.
They can be expensive, but rates are reducing as they become more common. Lumber frames are an excellent natural insulator that can match some home styles. Lumber frames must be made from species that have naturally high durability or be dealt with to prevent decay and contortion. Inspect that the lumber is sourced from a sustainably managed forest.
However, this can lead to gaps that enable air infiltration unless good draught sealing (weather removing) is set up. u, PVC is a type of plastic (unplasticised polyvinyl chloride, also referred to as rigid PVC). u, PVC frames offer excellent thermal performance, frequently better than timber or thermally broken aluminium. u, PVC is long enduring and requires extremely little maintenance, and can be moulded into complex profiles that supply excellent air seals.
u, PVC windows and doors have exceptional thermal efficiency Picture: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the external sections with either a lumber or u, PVC inner area. These integrate the low upkeep and resilience of aluminium with much improved thermal efficiency.
