D_F flat roof windows

Flat roof deck mounted skylight D_F

The benefits of natural illumination of the building are unquestionable but it happens that in buildings with flat roofs it is not always possible to install standard vertical windows. Ideal solution in such cases is installation of specially designed products for flat roofs.

 

Characteristics:

  • FAKRO thermo flat roof skylights illuminate interiors with natural light, provide room ventilation and combine high functionality with perfect thermal insulation parameters.
  • Now every room under the flat roof can be warm and full of natural light.
  • Every room should provide a source of natural light for a dweller to feel comfortable.
  • The ideal solution in such cases is the installation of specially designed flat roof skylights.

DEF SOLAR

The autonomous DEF Solar window is powered by solar energy through the special PV panel, therefore the product does not require connection to the electrical system in the building. The PV panel integrated with the battery allows for operation even on cloudy days. Proven design ensures excellent performance and impeccable aesthetics. Convenient operation with the wireless Z-Wave system using the remote control. Remote control is included to window.

 

GLAZING

The type F has energy-efficient with triple DU6 glazing. The external glass is 1/4" (6mm) thick and laminated for superior protection against impact such as hail. The high R-value and tightness of the triple and quadruple glazed skylights make this skylight suitable for energy-efficient and passive house projects. The heat transmittance co-efficient for the whole skylight with triple glaze (DU6) is U=0.70 W/m2K*(to EN 14351-1) while the heat transmittance co-efficient for the whole skylight is U=0.64 W/m2K** (to EN 14351-1), making.

*equivalent R-Value 8.1

**equivalent R-Value 8.9

SOUND INSULATION

The DEF flat roof window featuring a double-chamber DU6 glazing has been tested for sound insulation during heavy rain. The result, LIA= 36 [dB]*, confirms the high level of resistance against sound penetration making the skylight ideal for sound reduction. 

*as per ISO 10140-1/A2:2014; The result also applies to skylights: fixed DXF DU6, manual DMF DU6, fixed DXF SECURE (PK) DU6, manual DMF SECURE (PK) DU6, roof access DRF DU6

Please note, standard glazing units are only suitable for installation of up to 3,000 feet above sea level.

 

ACCESSORIES
External and internal blinds are available in a variety of colors and can be installed while the skylight is being installed or anytime after the skylight’s installation. External awning blinds are the most effective method of protecting rooms from overheating from the heat of the sun. Both internal and external blinds are available in solar, electrical or manually operated versions. Various control accessories such as a wall switch and opening rods are also available for the electrically (DEF) and manually (DMF) operated skylights.

 

INSTALLATION RANGE
The D_F flat roof skylight is suitable for roof pitches between 2 and 15 degrees (maximum slope up to 3/12).

 

AVAILABLE SIZES
A wide range of standard sizes make the D_F skylight suitable for retrofits and new builds in North America. Standard sizes available here.
