Looking for roof lanterns & skylights in Penzance? S&K Glazing has been installing across Cornwall for over a decade. A roof lantern or skylight transforms a single-storey extension or rear kitchen-diner into a light-filled space without adding height.
A roof lantern or skylight transforms a single-storey extension or rear kitchen-diner into a light-filled space without adding height. S&K Glazing installs Korniche, Atlas and Stratus aluminium roof lanterns up to 5m wide, plus flat skylights and walk-on glass floors with self-cleaning, solar-control glass.
Penzance's granite Georgian heritage, coastal Victorian terraces, and modern St Michael's Way commercial expansion drive heritage and coastal-spec demand across TR18-TR20. Listed-building consents and salt-resistant aluminium installations are both core to our Cornwall workload here.
For doors and glass extensions in Penzance, residential property style typically drives the design brief across South West — whether that's contemporary aluminium bifolds spanning a garden-facing rear elevation, slim-frame sliding doors that maximise glass area on a modern extension, or heritage French doors fitted to a period façade. Most commonly we're working across TR18 and TR20 postcodes. Typical lead time from survey to install: 4-6 weeks for standard configurations, 8-10 weeks for bespoke or large-span builds.
We measure the rooflight aperture and check structural opening, kerb height and timber framing. We help you choose between traditional roof lantern (pitched ridge) and modern flat skylight.
Korniche lanterns: 1-2 week lead time. Custom Atlas or Stratus: 3-4 weeks. Flat skylights: 2-3 weeks for standard sizes.
Roof lantern installation usually requires coordination with your roofer to fit upstand kerbs first. We can supply pre-fabricated kerbs or work alongside your roofer.
