Why do hinged systems insulate better than sliding ones?

Because the sash presses against continuous perimeter gaskets, there are none of the unavoidable joints created along the tracks of a sliding frame. Air infiltration is practically eliminated, which improves both thermal and acoustic performance.

What exactly is a tilt-and-turn mechanism?

It is a mechanism that offers two operating positions with a single handle: full inward opening and tilting of the sash from the top. This way you ventilate the room in a controlled manner without the sash swinging in the wind.

Do inward opening sashes take up room space?

The sash needs a clear path towards the interior, so furniture and curtains must be planned accordingly. In narrow spaces we suggest tilt-only operation, single sashes or a combination with a fixed section.

Can the sashes be adjusted over time?

Yes, modern hardware allows three-dimensional adjustment, so the position of the sash and the pressure on the gaskets can be corrected. A single technician visit is usually enough to restore perfect operation.

What certificates accompany your frames?

Every unit is delivered with CE marking and a technical data sheet stating thermal transmittance, air permeability, water tightness and wind load resistance. These documents are also required for energy upgrade programmes.
