Laminated glass is often used in locations in the home most prone to injury from human effect such as restrooms, doors, around staircases and in areas close to the floor (it satisfies the requirements of 'safety 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 quickly cooled again. This process makes it much stronger than standard glass it can withstand greater impact loads prior to breaking. It likewise makes it much safer due to the fact that, when it does shatter, it gets into many little cubic pieces instead of hazardous shards.
However, 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 attached 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 made IGU, since it is impossible to totally seal the border, but it can offer great sound control. Window movies are a thin polymer movie containing an absorbing color or reflective metal layer, with an adhesive backing. They adhere to your glazing to alter its colour or make it reflective.
Applied to existing glass, some window movies can cut in half the overall SHGC of the window by taking in and/or reflecting solar radiation. This can be particularly advantageous in hotter climates where cooling is the primary concern, or on east and west elevations directly exposed to long periods of sunlight. However, window films might likewise decrease visible light transmittance.
For this factor, it is typically best to utilize a certified installer of window film. Frames have a substantial effect on the thermal efficiency of windows and doors, due to the fact that energy can be acquired and lost through the frame, as well as through the glass. Various types of frame will enable various levels of heat gain and loss, so mindful choice of frame is necessary for efficient passive design.
Aluminium is also an extremely excellent conductor of heat and will decrease the insulating worth of a glazing unit, 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 minimizes the heat flowing through the frame.
They can be pricey, however prices are reducing as they end up being more common. Timber frames are a good natural insulator that can fit some house designs. Wood frames must be made from types that have naturally high resilience or be dealt with to prevent decay and contortion. Inspect that the wood is sourced from a sustainably managed forest.
However, this can result in spaces that permit air infiltration unless good draught sealing (weather condition removing) is installed. u, PVC is a type of plastic (unplasticised polyvinyl chloride, likewise referred to as rigid PVC). u, PVC frames supply exceptional thermal performance, often much better than timber or thermally damaged aluminium. u, PVC is long enduring and requires very little maintenance, and can be moulded into complex profiles that supply outstanding air seals.
u, PVC doors and windows have exceptional thermal efficiency Photo: Ben Wrigley (Light House Architecture and Science) Composite frames use aluminium profiles on the outer areas with either a wood or u, PVC inner section. These integrate the low maintenance and toughness of aluminium with much improved thermal efficiency.
