For upvc roof lanterns in Carmarthenshire, we offer both routes: supply-only with delivery for builders and DIYers, and full installation by our own teams in Carmarthen, Llanelli, Ammanford and county-wide.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Carmarthenshire work means dealing with rural farmhouses and market-town stock with steady conversion and extension demand, and our surveyors specify accordingly rather than quoting blind.
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.
Quality modern uPVC carries UV stabilisation and colourfast foils with long guarantees. The yellowing associated with older white plastic belongs to a previous generation of material.
With reinforced ridges, uPVC handles standard domestic sizes comfortably. For very large spans we'd steer you to aluminium, where the engineering headroom is greater.
Yes — the glazing options are identical to our aluminium range, including self-clean coatings and blue or neutral solar control.
Typically 25–40% on a like-for-like size, depending on spec. On a standard kitchen-extension lantern that's a saving worth having if the slimmer aluminium bars aren't a priority.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
