Laminated glass is frequently used in locations in the house most vulnerable to injury from human effect such as bathrooms, doors, around staircases and in locations close to the flooring (it meets the requirements of 'shatterproof glass' that is mandated for usage in these areas by Australian Standard AS 1288 Glass in buildings).
Toughened glass has been 'tempered' by being reheated and rapidly cooled once again. This procedure makes it much stronger than standard glass it can resist higher impact loads before breaking. It also makes it more secure since, when it does shatter, it gets into many small cubic pieces rather than hazardous fragments.
Toughened glass has no thermal or acoustic benefits 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 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 made IGU, given that it is impossible to absolutely seal the perimeter, however it can offer good noise control. Window movies are a thin polymer movie containing a taking in color or reflective metal layer, with an adhesive support. They stick to your glazing to alter its colour or make it reflective.
Applied to existing glass, some window films can cut in half the overall SHGC of the window by taking in and/or reflecting solar radiation. This can be especially useful in hotter climates where cooling is the main concern, or on east and west elevations straight exposed to long durations of sunshine. However, window movies may likewise minimize visible light transmittance.
For this reason, it is usually best to use an accredited installer of window movie. Frames have a substantial influence on the thermal performance of doors and windows, due to the fact that energy can be gained and lost through the frame, in addition to through the glass. Different types of frame will allow different levels of heat gain and loss, so cautious option of frame is necessary for effective passive design.
Aluminium is likewise a very excellent conductor of heat and will decrease the insulating value of a glazing system, unless specifically engineered to reduce this. A 'thermally broken' frame is made up of 2 aluminium areas linked by a structural insulator (typically a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and minimizes the heat flowing through the frame.
They can be pricey, but costs are reducing as they end up being more common. Timber frames are a great natural insulator that can fit some house styles. Timber frames need to be made from types that have naturally high sturdiness or be treated to avoid decay and contortion. Examine that the lumber is sourced from a sustainably handled forest.
This can result in gaps that enable air seepage unless good draught sealing (weather stripping) is set up. u, PVC is a form of plastic (unplasticised polyvinyl chloride, likewise known as rigid PVC). u, PVC frames offer outstanding thermal performance, frequently better than wood or thermally broken aluminium. u, PVC is long lasting and requires very little maintenance, and can be moulded into complicated profiles that offer excellent air seals.
u, PVC doors and windows have exceptional thermal efficiency Photo: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the outer areas with either a lumber or u, PVC inner area. These combine the low upkeep and sturdiness of aluminium with much enhanced thermal performance.
