Laminated glass is frequently utilized in locations in the house most susceptible to injury from human impact such as restrooms, doors, around staircases and in locations close to the floor (it satisfies the requirements of 'security glass' that is mandated for use in these areas by Australian Standard AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and quickly cooled again. This process makes it much more powerful than standard glass it can withstand greater effect loads prior to breaking. It likewise makes it safer since, when it does shatter, it breaks into many little cubic pieces rather than hazardous shards.
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 too thermally as a manufactured IGU, given that it is difficult to completely seal the border, however it can offer great noise control. Window movies are a thin polymer movie including an absorbing color or reflective metal layer, with an adhesive support. They adhere to your glazing to change its colour or make it reflective.
Applied to existing glass, some window movies can halve the overall SHGC of the window by absorbing and/or showing solar radiation. This can be especially beneficial in hotter climates where cooling is the main concern, or on east and west elevations directly exposed to extended periods of sunlight. Window films might also reduce visible light transmittance.
For this factor, it is typically best to utilize an accredited installer of window movie. Frames have a considerable effect on the thermal performance of doors and windows, due to the fact that energy can be gained and lost through the frame, along with through the glass. Different types of frame will permit various levels of heat gain and loss, so mindful choice of frame is essential for reliable passive style.
Nevertheless, aluminium is also a great conductor of heat and will reduce the insulating worth of a glazing system, unless specifically engineered to lower this. A 'thermally broken' frame is made up of 2 aluminium sections linked by a structural insulator (typically a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and lowers the heat streaming through the frame.
Lumber frames are a great natural insulator that can fit some home designs. Wood frames must be made from types that have naturally high toughness or be treated to avoid decay and contortion.
However, this can lead to gaps that enable air seepage unless great draught sealing (weather condition stripping) is installed. u, PVC is a kind of plastic (unplasticised polyvinyl chloride, likewise understood as stiff PVC). u, PVC frames provide outstanding thermal performance, typically much better than wood or thermally damaged aluminium. u, PVC is long enduring and needs extremely little upkeep, and can be moulded into complex profiles that provide outstanding air seals.
u, PVC doors and windows have excellent thermal performance Image: Ben Wrigley (Light House Architecture and Science) Composite frames use aluminium profiles on the outer sections with either a lumber or u, PVC inner section. These combine the low maintenance and durability of aluminium with much enhanced thermal efficiency.
