Cor 60 is one of Cortizo's most widely specified window systems — a middle-of-the-road choice that works well on both refurbishments and lower-specification new builds.
Where it earns its place
Cor 60 keeps aluminium within reach on projects where budget rules out the more expensive systems, but where a switch to uPVC would compromise the look of the finished house.
Thermal figures
A Uw from 1.3 W/m²K puts Cor 60 in the same territory as the entry-level Schüco AWS — perfectly adequate for most residential refurbishment work.
Reading the small print
Cortizo publishes several thermal-break variants of Cor 60. When comparing quotes, it is worth asking which variant a supplier is proposing rather than accepting the headline figure alone.
Readers looking for a Stevenage-based supplier will find 5EC's aluminium windows a practical first port of call — the firm holds authorised-supplier status for the brands covered here.
