Aluminium Greenhouses

About Our Aluminium Greenhouses

Aluminium-framed greenhouses are the low-maintenance choice for British gardens. The frame will not rot, warp, or need annual treatment like timber. A powder-coated finish resists rust and holds its colour for decades. We stock 860 in-stock aluminium models, with prices from £229 for a compact lean-to up to large professional structures.

The slim aluminium glazing bars let in more light than thick wooden frames. That extra light matters in our short UK winters. Colours run from plain mill-finish silver through to forest green, anthracite grey, and black. Choosing your frame is only half the job. Our wooden greenhouses suit gardeners who want a traditional look, while our plastic greenhouses work for tight budgets and balconies. Most aluminium models take horticultural glass, toughened safety glass, or twin-wall polycarbonate.

Frequently Asked Questions

• Does an aluminium greenhouse need painting or treating?

  No. Aluminium frames need no painting or treatment. The metal resists corrosion on its own, and powder-coated frames hold their colour for years. A wash with soapy water once a year keeps the glass clear.

• Will an aluminium frame rust?

  No, aluminium does not rust. It forms a natural oxide layer that protects the metal. This makes it a sound choice for coastal gardens where salt air corrodes steel and rots timber.

• Which glazing suits an aluminium greenhouse best?

  Toughened safety glass suits most gardens. It is rigid, safe near children, and stands up to strong wind. Polycarbonate insulates better but flexes in exposed spots, so pick it only for sheltered sites.

• How long does an aluminium greenhouse last?

  A quality aluminium greenhouse lasts 20 to 30 years. Set it on a flat, square base and clean the glass now and then. Most models carry a manufacturer warranty of 5 to 25 years.

• Is aluminium better than a wooden or plastic frame?

  Aluminium needs the least upkeep of the three. Wood looks warmer but needs yearly treatment, and plastic frames suit only small structures. For a lasting greenhouse with little fuss, aluminium wins.
