modern roof windows - ecowise and beautiful

Plenty of light, a feeling of space, fresh air, pleasant and elegant attic element and full functionality with low thermal-transmission.

1) Frame and wing of a roof window

Quality and aesthetic properties, as well as finishing of the material used are of key importance. We produce wooden roof windows and use the best quality wood with the highest coefficient of elasticity: seasoned, dried and beautiful solid pine wood. In our philosophy such material can not be compared to PVC or trusses glued from small pieces.

The wood is protected against mould and fungi and than provided with primer and a final high-pressure sprayed paint coat of water-dilutable glazing paint.

2) Glazing units, low thermal transmission

We use double-glazing units by Pilkington, including the patented "self-cleaning" units ActivTM, frequently also Heat Mirror system (patented double-glazing units with a third foil layer, performing impressive thermal-transmission coeficient Ug=0,33W/m2K).

3) Glazing technology

The technology of glazing is the key to low thermal losses of a house. In case of Solara roof windows, the double-glazing units are together with the wing of the window deeply embedded into the window frame, which - in combination with double-edge sealing - allows us to achieve top quality thermal insulation. That is of key importance not only during winter season, but also in burning summer heats, when a roof is loaded enormously.

4) Outside flashings and lining

The material, its surface and processing, is also important for the outside sheating. We use rolled paint aluminium sheets (with a warranty of 60 years), copper, Rheinzink or titan-zinc.

 

Frequently we customize our products – just choose the colour shade, kind of wood, size and shape...

Advantages of Solara roof windows

  • the frames and wings are made of beautiful, seasoned and dried solid pine wood with perfect finishing
  • we develop and use non-complicated and efficient control systems; Solara roof windows have "invisible" fittings 
  • Solara roof windows are fully adjustable, i.e. the wing maintains its position at all levels of opening and the opening stiffnessis variable,
  • the thermal transmission of used double-glazing units reaches the level of Ug=1,1W/m2K; on request down to Ug=0,33W/m2K

System of opening

We produce centre-pivot models (Lido, Happy), top-hung models (Praktik) and side-hinged model (Side). While choosing the right option it is important to consider the actual use. The centre-pivot roof windows are simpler and less expensive; however, they open "at head level" and occupy space in the room. The quiestion is to what extent you wish to use the area at the bottom of your roof window and at what height above the floor level the roof window will be positioned.

The golden rule is to have the axis of the roof window wing opening at least 20 cm above head height.

 

I wish you a pleasant living ín attic.
