A Real History When It Comes To Quality

Ventrolla was founded in 1983 by Robert Tunnicliffe who previously worked at Ford Motors developing specialised high performance gaskets and seals. The name 'Ventrolla' is a slightly warped portmanteau of 'Ventilation Control'.

Robert turned his hand to draught proofing sash windows after his wife noticed it becoming increasingly difficult to keep their home warm during the colder months and so Bob, using his expertise at Ford developed the first perimeter sealing system and installed it himself.

Immediately the draughts, rattles and dust ingress were banished! After the initial success of the hand-made prototype Bob went on to found Ventrolla and patented both the perimeter sealing system and the sash removal system, both of which, 35 years on are still core products in the Ventrolla service and make our offering unique.

In 1986 the Ventrolla Perimeter Sealing System was awarded the prestigious Design Council Award.

Our first branch opened in the beautiful North Yorkshire town of Harrogate and now over 35 years and 100,000 sash windows later we operate nation wide and have established ourselves as the market leader in the repair, restoration and replacement of wooden sash windows.
