Laminated glass is typically used in areas in the home most susceptible to injury from human effect such as restrooms, doors, around staircases and in areas close to the floor (it satisfies the requirements of 'shatterproof 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 again. This procedure makes it much stronger than standard glass it can withstand higher effect loads prior to breaking. It also makes it more secure due to the fact that, when it does shatter, it breaks into lots of small cubic pieces rather than dangerous shards.
Toughened glass has no thermal or acoustic advantages 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 attached to the within the frame or openable sash with a secondary frame or with magnetic strips.
Secondary glazing will not carry out as well thermally as a produced IGU, given that it is difficult to absolutely seal the boundary, however it can supply great sound control. Window films are a thin polymer film consisting of a soaking up color or reflective metal layer, with an adhesive support. They stay with your glazing to alter its colour or make it reflective.
Applied to existing glass, some window movies can halve the general SHGC of the window by taking in and/or showing solar radiation. This can be especially beneficial in hotter climates where cooling is the main issue, or on east and west elevations directly exposed to long durations of sunlight. Window movies may also minimize visible light transmittance.
For this factor, it is generally best to use an accredited installer of window movie. Frames have a significant impact on the thermal efficiency of windows and doors, due to the fact that energy can be gained and lost through the frame, in addition to through the glass. Different kinds of frame will allow various levels of heat gain and loss, so careful choice of frame is essential for reliable passive style.
However, aluminium is likewise a very excellent conductor of heat and will decrease the insulating value of a glazing system, unless particularly engineered to minimize this. A 'thermally broken' frame is comprised of 2 aluminium sections connected by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and reduces the heat flowing through the frame.
They can be expensive, but costs are reducing as they end up being more typical. Wood frames are a good natural insulator that can match some home designs. Wood frames must be made from species that have naturally high durability or be dealt with to prevent decay and deformation. Inspect that the timber is sourced from a sustainably handled forest.
Nevertheless, this can result in gaps that enable air infiltration unless great draught sealing (weather stripping) is installed. u, PVC is a kind of plastic (unplasticised polyvinyl chloride, also understood as rigid PVC). u, PVC frames provide excellent thermal performance, typically better than wood or thermally broken aluminium. u, PVC is long enduring and needs very little maintenance, and can be moulded into intricate profiles that offer exceptional air seals.
u, PVC doors and windows have exceptional thermal performance Photo: Ben Wrigley (Light House Architecture and Science) Composite frames use aluminium profiles on the external sections with either a timber or u, PVC inner section. These combine the low maintenance and resilience of aluminium with much enhanced thermal performance.
