Insulation refers to an energy savings measure, which provides resistance to heat flow. Naturally, heat flows from a warmer to a cooler space. By insulating a house, one can reduce the heat loss in buildings in cold weather or climate, and reduce the heat surplus in warmer weather or climate. Insulating a house has several benefits such as energy savings and therefore cost savings and increased comfort.
There are several types of insulation against heat loss in cold climates, each with its own technical characteristics and financial costs and benefits. Insulation measures are generally one of the most cost effective energy savings measures.
Thus, insulation limits the need for heating or cooling the house. Heat losses or heat surpluses arise because of differences between the indoor and outdoor air temperature. Heat, normally flows from a warmer to a cooler space, and the temperatures will converge to an equilibrium temperature, a physical phenomenon based on mechanisms like transmission (the heat flow through materials) and ventilation (heat flow by air). Insulation aims at reducing the speed of this convergence of temperature in order to decrease the need for heating or cooling and thus a lower dependence on the use of energy.
FAKRO roof windows are designed not only to provide a focal point for any room whether you use them individually or in combinations, but also promote saving of energy. Their stylish appearance is matched by the highest standard of manufacturing and finishing which means one can rest assured they will go on looking good apart from accruing savings for years to come. FAKRO windows offer the perfect combination of style, sustainability, security and long life.
To achieve such high performance involves ongoing refinement and improvement to every roof window that is designed by FAKRO.
What really sets FAKRO windows apart is their low level of heat loss. Unlike some manufacturers who provide U-values just for glazing units, FAKRO provides information for the whole window. When comparing their performance with other products you will see how their non-vented, quadruple glazed FTT U8 Thermo, with a U-value of 0.58 W/m2K, leads the market. Their standard FTP-V centre pivot windows also offer a level of performance which competing windows invariably fail to match.
The FTT window with innovative structure ensures excellent thermal insulation performance and large energy savings. The FTT U8 Thermo window featuring Uw = 0.58 W/m2K is the most energy-efficient roof window with a single glazing unit available in the market. It already significantly exceeds the energy-efficiency requirements for roof windows which will become effective from 2021. The FTT U8 Thermo complies with passive construction requirements, which is confirmed by the Passive House certificate.
Triple chamber glazing unit U8 with Ug = 0.3 W/m2K is set in a specially designed sash frame, which offers wider wooden profiles in comparison with standard windows. The window is equipped with five seals. Such a structure minimises thermal bridging and provides improved insulation.
The FTT U8 Thermo window is supplied and installed with EHV-AT Thermo flashing, which enables window insulation above the roof surface. Flexible insulating material is glued to the inside of the flashing which adheres tightly to the window frame forming thermally insulated frame.
As standard, the window is equipped with XDK insulation flashing kit, which enables fast and proper installation of thermal insulation, air permeable membranes and air tight membranes around the window.
Application of comprehensive solution ensures a fulfilling of the energy-efficient function of the window which in turn reduces heat loss as well as bills for heating the building.
The FTT U8 Thermo window is equipped with a glazing unit consisting of four toughened panes featuring increased resistance. This improves safety of use in the attic even during heavy rain or hail. Therefore, these windows come with a lifetime warranty against hail.
