Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Penarth and the wider county, housing stock runs to Victorian terraces and bay-fronted semis where side-return and rear extensions make lanterns a staple. We've specified and supplied for exactly these property types across Cardiff, so recommendations come from real local precedent.
Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.
Penarth, Whitchurch (Cardiff), Radyr and Cardiff and the rest of Cardiff all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
No — it's pyrolytic, fired into the glass surface during manufacture rather than applied afterwards, so it lasts the life of the unit with nothing to renew.
That's the standard pairing — one sealed unit with the self-clean layer outside and the solar-control coating within. Most lantern glass we supply ships exactly that way.
Usually — if your frame takes standard sealed units we can manufacture self-clean replacements to size and fit them in situ, upgrading the glass without touching the structure.
The self-clean layer itself is virtually invisible. Any tint you see comes from the solar-control side of the unit — blue is the popular choice, neutral keeps the glass colour-true.
Yes — installation is available across Penarth and Cardiff, and if you'd rather buy supply-only, kerbside delivery to Penarth is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Penarth usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
