Window Restoration for Heritage Listed Mansion by Ventrolla

This $18,000,000 Heritage listed Mansion is currently going through a full renovation. Ventrolla were engaged to refurbish the existing heritage windows, where we conducted minor repair work to the frames and sashes. The existing old sash cord was exchanged with our modern, reinforced sash cord. We then upgraded the performance of the windows and French doors by installing our patented VPSS draught proofing system to eradicate rattling of the windows, increase the windows energy rating by 30%, and decrease noise intrusion from 6 to 10 decibels.

In addition to this we installed 6.5mm Hush safety glass (to the east side of the building which faces a busy road) which is engineered to drown out 20% of the noise intrusion. Using this combination the windows and French doors perform just like - if not better than - a new window, and costs a fraction of the price compared to replacing with new joinery.
