Large Scale Residential Heritage Window Upgrades with Ventrolla

Ventrolla have been engaged to refurbish the existing heritage windows (both double hung sash and casement windows) for this large residential building in Elizabeth Bay, where we conducted repair work to the frames and sashes due to rot. We exchanged the existing old sash cords with our modern reinforced, waxed sash cords. We've then upgrade the performance of the windows by installing our patented VPSS Draught Proofing System, which eradicated rattling of the windows, increases the windows energy rating by 30%, and decreases noise intrusion from 6-10 decibels.

This is a staged project and is likely to take between 18-24 months to complete. We are working with the tenants strata committee to create a work schedule that's suits each individual apartment owner and their renovation needs. There are 140 windows in total.
