Project Description:

This project targeted void properties to allow a deep retrofit compared to when tenants are in place.

The measures installed varied according to the individual property and existing heating solution in place with measures including:

• Improvement of existing windows with double glazing
• Improvement and treatment to walls/roof/floor with insulation
• Deployment of air tightness measures
