A typical window insulation film kit, consisting of plastic shrink film (folded-up) and a roll of double-sided tape. One commonly used film is a heat-shrink plastic which is attached to the window frame using double-sided pressure-sensitive tape. A hair dryer is used to remove creases and improve optical clarity.
One university study shows that this heated glass technology is more efficient than other electric heating and can be more efficient than natural gas heating. [5] Some environmentalists dispute the idea that this is an efficient heating system because even high e-value windows are poor insulators compared to insulated walls, and they believe ...
It is the ratio of solar gain (due to direct sunlight) passing through a glass unit to the solar energy which passes through 3mm Clear Float Glass. [1] It is an indicator of how well the glass is thermally insulating ( shading ) the interior when there is direct sunlight on the panel or window.
Window insulation reduces heat transfer from one side of a window to the other. The U-value is used to refer to the amount of heat that can pass through a window, called thermal transmittance, with a lower score being better. [1] The U-factor of a window can often be found on the rating label of the window.
When the sun heats a roof, it's primarily the sun's radiant energy that makes the roof hot. Much of this heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor.
Living in an apartment with old, single pane windows? Brr! If you're one of the estimated 3/4 of renters who pay separately for utilities you'll quickly discover the cost. Pull out the thermal ...
An attic fan installed underneath a roof. A powered attic ventilator, or attic fan, is a ventilation fan that regulates the heat level of a building's attic by exhausting hot air. A thermostat is used to automatically turn the fan off and on, while sometimes a manual switch is used. An attic fan can be gable mounted or roof mounted. Additional ...
Brise-soleil can comprise a variety of permanent sun-shading structures, ranging from the simple patterned concrete walls popularized by Le Corbusier in the Palace of Assembly [3] to the elaborate wing-like mechanism devised by Santiago Calatrava for the Milwaukee Art Museum [4] or the mechanical, pattern-creating devices of the Institut du Monde Arabe by Jean Nouvel.
