i3 BBA Approved Window Sealing System from illbruck

illbruck i3 provides a state-of-the-art universal sealing system for the perimeter sealing of windows, that seals OUT weather while sealing IN comfort and energy savings.
i3 is an externally weatherproof system, which also prohibits the formation of condensation. This is a problem that can lead to a reduction in the level of thermal insulation, damage to building components and mould formation.

Hi what's the procedure when replacing old double glazed windows in a traditional bungalow which has roughcast walls in UK. Or is this method just for new-builds?

Would you do it any differently if installting aluminium windows into a timber frame?
