Extensive Warranties

Market-leading heritage window & door renovation company

Founded in 1983 by Robert Tunnicliffe, Ventrolla is soon to celebrate 40 years' of renovating, repairing, draught-proofing and replacing wooden sash and casement windows. Taking our name from the slightly warped portmanteau of 'Ventilation Control', Ventrolla’s founder utilised skills from his previous job developing specialised gaskets and seals at Ford Motors, creating the first perimeter sealing system for draught-proofing historic sash windows - and the rest, as they say, is history!

A history of quality wooden windows & doors

Designed to eliminate draughts, rattles and dust ingress, the Ventrolla Perimeter Sealing System (VPSS) was awarded the prestigious Design Council Award (Engineering Components) soon after its invention in 1986. Using strips of low-friction Weatherfin polypropylene pile to seal the gaps, this patented system, along with our innovative Sash Removal System (SRS), are still core heritage renovation products 40 years on.

With workshops based in Harrogate, Henley-on-Thames, and Lockerbie, manufacturing our products in-house gives our customers complete control of the process from start to finish – from conception to completion and everything in between.
