Laminated glass is typically utilized in locations in the house most vulnerable to injury from human impact such as bathrooms, doors, around staircases and in areas near the floor (it satisfies the requirements of 'security glass' that is mandated for use in these locations by Australian Standard AS 1288 Glass in structures).
Toughened glass has been 'tempered' by being reheated and quickly cooled once again. This process makes it much more powerful than standard glass it can resist greater effect loads before breaking. It likewise makes it safer since, when it does shatter, it burglarizes many little cubic pieces rather than unsafe 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 attached 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 manufactured IGU, because it is difficult to absolutely seal the border, however it can provide good sound control. Window films are a thin polymer movie containing an absorbing 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 movies can cut in half the overall SHGC of the window by taking in and/or reflecting solar radiation. This can be especially advantageous in hotter environments where cooling is the primary concern, or on east and west elevations directly exposed to extended periods of sunlight. Window movies may also minimize visible light transmittance.
For this factor, it is normally best to utilize a certified installer of window film. Frames have a considerable influence on the thermal efficiency of doors and windows, due to the fact that energy can be gained and lost through the frame, as well as through the glass. Different kinds of frame will permit different levels of heat gain and loss, so cautious choice of frame is very important for efficient passive design.
Aluminium is likewise a very good conductor of heat and will decrease the insulating worth of a glazing system, unless particularly crafted to decrease 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 flowing through the frame.
They can be expensive, however prices are reducing as they end up being more common. Timber frames are a great natural insulator that can fit some home styles. Lumber frames must be made from species that have naturally high toughness or be treated to avoid decay and deformation. Check that the wood is sourced from a sustainably managed forest.
This can result in gaps that permit air seepage unless good draught sealing (weather condition stripping) is set up. u, PVC is a form of plastic (unplasticised polyvinyl chloride, also known as rigid PVC). u, PVC frames offer excellent thermal performance, frequently much better than wood or thermally damaged aluminium. u, PVC is long enduring and requires extremely little maintenance, and can be moulded into intricate profiles that provide exceptional air seals.
u, PVC doors and windows have exceptional thermal performance Image: Ben Wrigley (Light Home Architecture and Science) Composite frames utilize aluminium profiles on the outer areas with either a lumber or u, PVC inner section. These combine the low maintenance and toughness of aluminium with much enhanced thermal performance.
