Laminated glass is frequently used in areas in the home most susceptible to injury from human impact such as bathrooms, doors, around staircases and in locations 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 procedure makes it much more powerful than basic glass it can withstand greater effect loads prior to breaking. It also makes it more secure since, when it does shatter, it gets into lots of small cubic pieces rather than dangerous fragments.
Toughened glass has no thermal or acoustic benefits over other glass of the very 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 perform as well thermally as a manufactured IGU, since it is difficult to absolutely seal the boundary, but it can supply excellent sound control. Window movies are a thin polymer film including a taking in dye 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 films can halve the overall SHGC of the window by taking in and/or reflecting solar radiation. This can be particularly useful in hotter environments where cooling is the primary issue, or on east and west elevations directly exposed to long periods of sunlight. Window movies may also reduce visible light transmittance.
For this factor, it is typically best to utilize a recognized installer of window movie. Frames have a considerable effect on the thermal performance of doors and windows, because energy can be acquired and lost through the frame, along with through the glass. Different kinds of frame will enable different levels of heat gain and loss, so careful choice of frame is necessary for reliable passive style.
Aluminium is likewise a very great conductor of heat and will reduce the insulating value of a glazing system, unless particularly engineered to lower 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 costly, but rates are reducing as they end up being more typical. Timber frames are a good natural insulator that can suit some home styles. Lumber frames need to be made from species that have naturally high resilience or be treated to avoid decay and contortion. Examine that the lumber is sourced from a sustainably managed forest.
This can result in spaces that permit air infiltration unless excellent draught sealing (weather condition removing) is installed. u, PVC is a kind of plastic (unplasticised polyvinyl chloride, also known as rigid PVC). u, PVC frames supply exceptional thermal efficiency, typically better than timber or thermally damaged aluminium. u, PVC is long enduring and needs really little upkeep, and can be moulded into intricate profiles that offer excellent air seals.
u, PVC windows and doors have exceptional thermal performance Picture: Ben Wrigley (Light Home Architecture and Science) Composite frames utilize aluminium profiles on the outer sections with either a timber or u, PVC inner area. These combine the low upkeep and sturdiness of aluminium with much improved thermal efficiency.
