Laminated glass is frequently used in areas in the house most vulnerable to injury from human impact such as bathrooms, doors, around staircases and in areas near the flooring (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 stronger than standard glass it can resist greater effect loads before breaking. It also makes it much safer because, when it does shatter, it gets into lots of little cubic pieces instead of dangerous fragments.
Toughened glass has no thermal or acoustic advantages over other glass of the exact same toning or density. 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 carry out too thermally as a made IGU, given that it is difficult to completely seal the perimeter, but it can supply good noise control. Window films are a thin polymer film containing a taking in color or reflective metal layer, with an adhesive backing. They stay with your glazing to change its colour or make it reflective.
Applied to existing glass, some window films can halve the total SHGC of the window by taking in and/or reflecting solar radiation. This can be particularly useful in hotter environments where cooling is the main issue, or on east and west elevations straight exposed to long periods of sunshine. Window films may also lower noticeable light transmittance.
For this factor, it is generally best to use a recognized installer of window movie. Frames have a substantial influence on the thermal performance of windows and doors, because energy can be gotten and lost through the frame, in addition to through the glass. Different types of frame will enable different levels of heat gain and loss, so careful option of frame is important 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 lower 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 streaming through the frame.
They can be costly, however prices are decreasing as they end up being more typical. Timber frames are a great natural insulator that can suit some house designs. Timber frames should be made from species that have naturally high sturdiness or be treated to prevent decay and deformation. Check that the lumber is sourced from a sustainably managed forest.
This can result in spaces that allow air infiltration unless great draught sealing (weather condition stripping) is set up. u, PVC is a form of plastic (unplasticised polyvinyl chloride, likewise known as stiff PVC). u, PVC frames supply exceptional thermal efficiency, often better than timber or thermally broken aluminium. u, PVC is long enduring and needs extremely little upkeep, and can be moulded into complex profiles that provide exceptional air seals.
u, PVC doors and windows have excellent thermal performance Picture: Ben Wrigley (Light House Architecture and Science) Composite frames use aluminium profiles on the outer sections with either a lumber or u, PVC inner area. These integrate the low maintenance and sturdiness of aluminium with much improved thermal efficiency.
