Ventrolla's unique Perimeter Sealing System and Wood Repair System mean renovation rather than replacement, so that all the charm and original character of Sash Windows can be retained.
Traditionally, a sash window requires a 3 mm gap around the sashes for functionality. Inevitably, this gap allows in draughts, dust and noise and is the source of annoying rattles. The installation into each window of the patented Ventrolla Perimeter Sealing System seals this gap and actually improves on the original by:
Eradicating rattles.
Eliminating draughts.
Minimizing dust & dirt ingress.
Increasing the energy efficiency.
Reducing external noise.
All work is done from inside the building negating the need for expensive scaffolding. Windows are always left secure and weatherproof overnight.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Ventrolla is consulted before specifying.
