Laminated glass is frequently utilized in areas in the house most prone to injury from human effect such as bathrooms, doors, around staircases and in locations close to the flooring (it satisfies the requirements of 'shatterproof glass' that is mandated for usage in these locations by Australian Standard AS 1288 Glass in buildings).
Toughened glass has been 'tempered' by being reheated and rapidly cooled once again. This process makes it much more powerful than basic glass it can withstand higher impact loads before breaking. It also makes it safer due to the fact that, when it does shatter, it breaks into numerous little cubic pieces rather than hazardous fragments.
Toughened glass has no thermal or acoustic advantages over other glass of the 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 carry out as well thermally as a made IGU, given that it is difficult to completely seal the boundary, but it can supply good noise control. Window movies are a thin polymer movie consisting of an absorbing dye or reflective metal layer, with an adhesive backing. They stay with your glazing to alter its colour or make it reflective.
Applied to existing glass, some window films can cut in half the general SHGC of the window by absorbing and/or showing solar radiation. This can be particularly useful in hotter climates where cooling is the primary issue, or on east and west elevations directly exposed to long periods of sunlight. Nevertheless, window movies may also reduce noticeable light transmittance.
For this factor, it is generally best to use a recognized installer of window film. Frames have a significant effect on the thermal efficiency of windows and doors, due to the fact that energy can be gained and lost through the frame, as well as through the glass. Various types of frame will allow different levels of heat gain and loss, so careful option of frame is essential for reliable passive design.
Nevertheless, aluminium is likewise a great conductor of heat and will reduce the insulating value of a glazing unit, unless specifically engineered to minimize this. A 'thermally broken' frame is made up of 2 aluminium sections linked by a structural insulator (generally a low-conductivity structural polymer). This 'breaks' the thermal connection through the aluminium and lowers the heat streaming through the frame.
They can be expensive, however rates are decreasing as they end up being more typical. Timber frames are a good natural insulator that can suit some house designs. Lumber frames need to be made from types that have naturally high toughness or be dealt with to prevent decay and contortion. Check that the timber is sourced from a sustainably handled forest.
(weather stripping) is set up.
u, PVC doors and windows have excellent thermal efficiency Picture: Ben Wrigley (Light Home Architecture and Science) Composite frames utilize aluminium profiles on the outer sections with either a lumber or u, PVC inner area. These combine the low maintenance and durability of aluminium with much enhanced thermal performance.
