Laminated glass is typically utilized in areas in the home most prone to injury from human impact such as restrooms, doors, around staircases and in areas close to the floor (it satisfies the requirements of 'shatterproof glass' that is mandated for use in these areas by Australian Basic AS 1288 Glass in structures).
Toughened glass has actually been 'tempered' by being reheated and rapidly cooled once again. This process makes it much more powerful than basic glass it can resist higher effect loads before breaking. It also makes it safer since, when it does shatter, it gets into lots of small cubic pieces rather than harmful fragments.
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 inside of the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not perform as well thermally as a manufactured IGU, given that it is difficult to absolutely seal the perimeter, however it can supply excellent sound control. Window movies are a thin polymer movie containing a soaking up 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 films can cut in half the total SHGC of the window by absorbing and/or showing solar radiation. This can be especially useful in hotter climates where cooling is the main issue, or on east and west elevations straight exposed to extended periods of sunlight. However, window movies might also lower noticeable light transmittance.
For this factor, it is usually best to utilize a recognized installer of window movie. Frames have a significant effect on the thermal efficiency of windows and doors, due to the fact that energy can be gotten and lost through the frame, as well as through the glass. Different types of frame will allow various levels of heat gain and loss, so mindful option of frame is very important for efficient passive design.
Aluminium is also a really great conductor of heat and will decrease the insulating worth of a glazing unit, unless particularly engineered to reduce this. A 'thermally broken' frame is comprised of 2 aluminium areas connected by a structural insulator (usually a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and reduces the heat streaming through the frame.
Wood frames are an excellent natural insulator that can suit some house designs. Timber frames should be made from types that have naturally high resilience or be treated to avoid decay and contortion.
However, this can result in spaces that enable air seepage unless good draught sealing (weather removing) is set up. u, PVC is a type of plastic (unplasticised polyvinyl chloride, likewise referred to as rigid PVC). u, PVC frames provide outstanding thermal performance, typically better than wood or thermally damaged aluminium. u, PVC is long enduring and needs really little upkeep, and can be moulded into intricate profiles that provide exceptional air seals.
u, PVC doors and windows have excellent thermal performance Photo: Ben Wrigley (Light House Architecture and Science) Composite frames utilize aluminium profiles on the outer sections with either a lumber or u, PVC inner area. These combine the low maintenance and resilience of aluminium with much improved thermal efficiency.
