Windows: Timber / Aluminium: Home Soft: HF310


A combination of timber/aluminium and highly insulating thermal foam in between the frame & sash.

The HF 310 provides excellent thermal insulation values, natural timber refined with subtle paints, weather-resistant aluminium on the outside render the HF 310 the most attractive option among the timber/aluminium windows. Due to the same, flush design of the aluminium clad, HF 310 can be combined with UPVC window KF 410. All around bonding of the glass pane (I-tec glazing) ensures excellent stability and security protection. Triple continuous gaskets protect the interior area from exposure to the rain.


Classic rounded design outside and inside
Can be perfectly combined with UPVC/aluminium windows due to same outside appearance
