Single to double glazing upgrades
Assess whether an existing single-glazed opening can accommodate insulated units or needs a different frame solution.

Single to double glazing upgrades — inspect frame depth before increasing glazing thickness, with the pane type, safe handling and timing confirmed.
Rebate depth, weight capacity and sightlines are checked before proposing a glazing-only upgrade.
The detail that matters
Can every single-glazed frame accept a sealed unit?
No. A suitable rebate and supporting frame are essential, and some openings require replacement joinery.
