Our RX 450 frames are used for both doors — with single- or double-leaf construction — and windows — with single- or multi-leaf construction — in open joint or double rebate seal versions, coplanar outside and overlapping inside. This special seal easily meets the most stringent requirements and offers greater insulation from external agents, thus improving the energy performance of your home.
Casement, fixed glass, tilting, tilt and turn, or parallel sliding windows may be installed.
