Laminated glass is frequently used in areas in the home most susceptible to injury from human effect such as restrooms, doors, around staircases and in locations close to the floor (it fulfills the requirements of 'security glass' that is mandated for usage in these areas by Australian Basic AS 1288 Glass in buildings).
Toughened glass has actually been 'tempered' by being reheated and quickly cooled again. This procedure makes it much stronger than basic glass it can withstand greater effect loads before breaking. It likewise makes it safer because, when it does shatter, it gets into numerous small cubic pieces rather than unsafe fragments.
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 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, because it is impossible to absolutely seal the border, but it can supply great noise control. Window films are a thin polymer movie including a soaking up color or reflective metal layer, with an adhesive backing. They stay with your glazing to alter its colour or make it reflective.
Applied to existing glass, some window movies can halve the overall SHGC of the window by soaking up and/or showing solar radiation. This can be especially useful in hotter environments where cooling is the primary issue, or on east and west elevations straight exposed to long durations of sunshine. However, window movies might also minimize noticeable light transmittance.
For this factor, it is typically best to use an accredited installer of window film. Frames have a significant impact on the thermal efficiency of windows and doors, because energy can be gained and lost through the frame, as well as through the glass. Different kinds of frame will permit various levels of heat gain and loss, so cautious choice of frame is crucial for effective passive style.
Aluminium is also an extremely good conductor of heat and will decrease the insulating value of a glazing system, unless particularly crafted to reduce this. A 'thermally broken' frame is made up of 2 aluminium sections connected by a structural insulator (typically a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and reduces the heat flowing through the frame.
They can be pricey, but prices are decreasing as they end up being more common. Timber frames are a good natural insulator that can suit some house styles. Wood frames must be made from types that have naturally high sturdiness or be dealt with to avoid decay and deformation. Check that the wood is sourced from a sustainably handled forest.
This can result in gaps that allow air infiltration unless good draught sealing (weather condition removing) is set up. u, PVC is a form of plastic (unplasticised polyvinyl chloride, also called stiff PVC). u, PVC frames provide excellent thermal efficiency, frequently much better than timber or thermally broken aluminium. u, PVC is long lasting and requires really little upkeep, and can be moulded into complicated profiles that provide excellent air seals.
u, PVC doors and windows have exceptional thermal efficiency Image: Ben Wrigley (Light Home Architecture and Science) Composite frames use aluminium profiles on the outer sections with either a timber or u, PVC inner area. These combine the low upkeep and toughness of aluminium with much improved thermal efficiency.
