Laminated glass is typically used in locations in the home most vulnerable to injury from human impact such as restrooms, doors, around staircases and in areas near 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 structures).
Toughened glass has actually been 'tempered' by being reheated and rapidly cooled once again. This process makes it much stronger than standard glass it can resist greater effect loads prior to breaking. It also makes it safer because, when it does shatter, it gets into many small cubic pieces rather than dangerous shards.
Toughened glass has no thermal or acoustic benefits over other glass of the exact same toning or thickness. 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, considering that it is impossible to absolutely seal the border, however it can provide great noise control. Window movies are a thin polymer film containing a soaking up color or reflective metal layer, with an adhesive backing. 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 absorbing and/or reflecting solar radiation. This can be particularly useful in hotter environments where cooling is the primary concern, or on east and west elevations directly exposed to extended periods of sunlight. Window films might also decrease noticeable light transmittance.
For this factor, it is normally best to use a certified installer of window film. Frames have a significant influence on the thermal performance of doors and windows, since energy can be gained and lost through the frame, in addition to through the glass. Various types of frame will allow various levels of heat gain and loss, so careful option of frame is necessary for effective passive style.
Aluminium is also a really great conductor of heat and will decrease the insulating worth of a glazing system, unless particularly crafted to minimize this. A 'thermally broken' frame is made up of 2 aluminium areas connected by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and decreases the heat streaming through the frame.
They can be expensive, however prices are decreasing as they become more typical. Wood frames are a great natural insulator that can fit some home designs. Timber frames need to be made from species that have naturally high toughness or be dealt with to prevent decay and deformation. Check that the timber is sourced from a sustainably handled forest.
Nevertheless, this can lead to spaces that permit air infiltration unless great draught sealing (weather condition removing) is installed. u, PVC is a type of plastic (unplasticised polyvinyl chloride, also known as stiff PVC). u, PVC frames supply outstanding thermal efficiency, frequently better than wood or thermally damaged aluminium. u, PVC is long lasting and needs extremely little upkeep, and can be moulded into intricate profiles that offer excellent air seals.
u, PVC doors and windows have outstanding 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 section. These combine the low maintenance and resilience of aluminium with much enhanced thermal efficiency.
