Insulated Flat-Roof Deck Mounted Skylights DEF, DMF, DXF - FAKRO

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.

D_F SKYLIGHT- COLORLINE VERSION

The ColorLine D_F thermo flat roof skylight is available in hundreds of different colors within the RAL Classic Palette to match a variety of exterior colors and designs.

GLAZING

The type F has energy-efficient with triple DU6 glazing. The external glass is 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 makes 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 8.9

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

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 overhearing 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 (minimum 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.

Flat roof skylights are available in three versions:

DEF - electrically opened

DMF - manually opened

DXF - non-opening

Skylight’s structure

The D_F flat roof skylight features a sleek modern look. It is characterised by excellent thermal insulation parameters. The structure of the frame is the same as for FAKRO domed skylights for flat roofs, however, the main difference is the glazing which is bonded using modern manufacturing technologies to produce a smooth and seam-free surface.

The electrically operated windows have a built-in sensor that automatically activates the sash closing function when it rains.

The structure and design of the DEF Z-Wave electrically-operated thermo flat roof skylight has earned it the prestigious German Red Dot Design Award in 2016.
