After the innovative products of our smartwin family earnd world wide acceptance as pioniering window developments, the window freaks do a further step on the way to energy efficient and economic buildings.

The start up of smartshell familiy is well done with even four wall and building systems certified by Passive House Institute. The names are smartshell timber frame G, smartwin timberframe E, smartshell solid and smartshell reno.

smartwin partners are now able to offer, beside the world wide known smartwin windows, very detailed knowledge about energy and cost efficient wall and building systems.

A close bond between this groups of craftsmen opens unforeseen saving potential. This gets most obvious with the certifiied enerPHit-system smartshell reno.

World wide we are the first that are able to abstain from the window frame and link window sash directely into the smartshell reno wall.
