At Grosvenor Restoration, our focus is to upgrade the performance of your existing period windows using the latest Vacuum Insulated Glazing Technology. We supply glass to your project and back this up with training, support and guidance on full renovation and installation techniques into existing period windows. This can be on-site if required with your chosen Contractor.
We deliver energy savings, heat comfort and noise reduction in a unit that is up to 10 times more efficient than existing single glazing and slim enough to be retrofitted into traditional period windows. Upgrading a traditional sash window becomes possible without detracting from its beauty.
