Timber, aluminium and highly thermally insulating thermal foam in between - this is a combination which promises only good results. Excellent thermal insulation values, beautiful natural timber refined with discreet varnishes and weather-resistant aluminium on the outside make HF 310 an instant classic among the timber/aluminium windows. Due to the same flush design of the aluminium clad, HF 310 can be combined with the UPVC window KF 410. All around gluing of the glass pane (I-tec glazing) ensures excellent stability and burglary protection. Three continuous gaskets protect the inside from the wet.
