Aluminium Greenhouses

An aluminium-framed greenhouse is the long-life, low-maintenance alternative to wooden-framed greenhouses: aluminium doesn't rust, doesn't need painting, and lasts 25+ years in UK weather. Aosom UK, Buy Sheds Direct and Cherry Lane Garden Centres between them stock 90+ aluminium greenhouses covering £8-£1,719. Standard sizes run 4x6, 6x4, 6x6 and 6x8 feet. Glazing: horticultural glass (the long-life choice, lasts decades, breaks in hailstorms); toughened safety glass (the family-pick, breaks into pebbles not shards); polycarbonate twin-wall (the lightweight, slightly less light transmission). The aluminium frame option starts about £100-£200 above the equivalent steel-framed greenhouse but pays back over the longer service life. Anchoring matters in any greenhouse, aluminium-framed builds particularly need fixing to a metal base plate or paving foundation, since the frame is light enough to lift in autumn storms. Most include 1-2 roof vents; auto-vent openers add £30-£60 each.
