Islington contains some of London's finest Victorian architecture, with iconic Victorian terraces lining streets from Angel to Highbury. The borough also boasts stunning Georgian squares in Barnsbury and Canonbury, all protected by strict conservation area regulations that prohibit external window alterations.
Our conservation-approved secondary glazing is the ideal solution. Installed internally behind your existing sash windows, it preserves the external appearance while dramatically improving comfort. Most installations do not require planning permission as they are completely invisible from outside.
Islington properties face significant noise challenges from busy roads like Upper Street and Essex Road, plus rail lines through the borough. Our acoustic glazing reduces external noise by up to 80%, while thermal insulation cuts heat loss by up to 65%, dramatically reducing heating bills.
Islington has over 40 conservation areas protecting its architectural heritage. We provide conservation-approved secondary glazing across all of them, including:
Reduce heat loss by up to 65% through your period windows. Essential for Islington's tall Victorian sash windows that are often sources of significant draughts.
Block up to 80% of traffic noise from busy Islington streets with our acoustic glazing options. Perfect for properties on Upper Street or near Essex Road.
Preserve your original windows and the character of your Victorian or Georgian property. Our fully reversible installations leave no permanent alterations.
Add security with laminated glass options, providing resistance to forced entry for ground-floor and basement windows common in Islington terraces.
