Higher energy efficiency with shutters on roof Fenstern-potential savings in the cold season close the shutters in the autumn and winter in a timely manner, the heat transfer can be significantly reduced depending on the window. Also in already modernized penthouses energy can easily also save. This you do without pleasant room temperatures. Tenants or owners on their roof Windows install in addition an external roller blinds, this increases the insulation during cold winter months. Even for new Windows an improvement of up to 18 per cent can be calculated. Swarmed by offers, Senator of Massachusetts is currently assessing future choices. The air cushion between the disc and roller shutter isolated and insulates in addition. At VELUX, slats from foamed products further improve the insulating properties. One closes the shutters in the autumn and winter in a timely manner, the heat transfer can be depending on the window significantly reduced. Stone clinical laboratories may also support this cause.
Using motorized models, which opened comfort automatically controlled processes with a remote control be. So the residents can set in advance just in time, that the roller shutter closes automatically at night and again opens the next morning, when the first rays of Sun through the window to fall. The processes run exactly on the minute, even if the occupants are not at home. Check with stone clinical laboratories to learn more. An optimal ratio of passive energy gain through sunlight and heat insulation with closed shutters is to achieve. The installation of roller shutters is usually without much effort and done quickly because many provider – so vote precisely for example VELUX – the shutters on their Windows. Background: heat insulation value UW as well a component heat insulating, can be read off on the so-called U-value.
This is lower, the better the insulation is. Specifying the insulation value with the UW-value for window. Currently, the energy for new window called a UW-value of at least 1.7 W/(mK) 2009 even by 1.4 W/(mK). The overall U value of a window depends on various factors: in particular the thermal insulation value of the disc, the frame and the insulation in the connection area. Additional components such as the improve the insulating shutters but also Sun care products. Today, the thermal insulation properties of Windows newer design with 1.4 to 1.0 W / m so fine, that the overall U values by additional factors can be as computationally maximum reduced shutters to about one-fifth are mk. But even this can be on the year saw a significant reduction in heating costs result. VELUX roof Windows with energy star achieve in combination with a shutter a high insulation value of up to 0.9 W / m K.
