Sash window renovation (timber).
Ventrolla offer a sash window renovation service that negates the need to fully replace existing timber sash windows. This process involved renovating the existing windows and then installing Ventrolla's unique Perimeter Sealing System, 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 (VPSS) seals this gap and actually improves on the original by:
All work is done from inside the building meaning no need for expensive scaffolding. Windows are always left secure and weatherproof overnight.

Ventrolla Wood Repair:
Ventrolla wood repairs are undertaken using Ventrolla VR90, formulated to give long lasting wood repairs beyond those normally carried out using conventional polyester wood fillers. VR90 is a patented two-part resin system and is designed to be used to impart the original strength to sash tenon joints, to fill large cavities in sills and to act as a powerful adhesive. It completely bonds with the parent wood and flexes when the wood contracts or expands. To achieve this bond, all decayed wood is removed exposing only sound wood. This is then stabilised using VR90 WS solution which penetrates the wood fibres to attain the permanent anchorage for the subsequently applied VR90 filler.
Sash removal system:
The Sash Removal System is a unique hidden system which allows the quick and easy removal of both top and bottom sashes internally. Staff beads can easily be detached from the window giving access to the bottom sash. Using the plastic cord holder, the sash cord can be unclipped from the window which allows the bottom sash to be completely removed. The parting beads can also be removed, allowing access to the top sash. The Ventrolla sash removal system allows all components of the window to be removed internally and brought into the building for convenient maintenance and painting, thereby avoiding the need for external scaffolding.
Sill replacement and lower box assembly:
Replacement sills can be provided to match original profiles. The original bottom section of the box linings is removed and Sill trenches are cut, the outer and inner linings are spliced to facilitate a flush and water tight finish.
A wide range of specialist locks and catches are available.
Windows can be sealed shut internally and externally with the Ventrolla Sealing and Pointing system VS10.
