Available with horticultural, long pane toughened glass or twin wall polycarbonate, the Birdlip also comes in aluminium, green or black finishes.

Cotswold greenhouses are designed to be almost maintenance free. Only occasional oiling of the moving parts, and general cleaning is all that is required. The manufacturers supply this building with a 12-year warranty and guarantee that your building lasts for many years.

Windows & Glazing

Cotswold greenhouses are supplied with a choice of glazing to best suit your circumstances. Traditionally horticultural glass has been used, allowing sunlight to stream into the greenhouse for maximum light and warmth, however they are also available in toughened safety glass as well which is especially comforting if you have small children. Twin-walled polycarbonate glazing is also available, and offers additional insulation and shields delicate plants from direct sunlight. This building comes with 1x Opening Roof Vent.

The area must be free from obstructions (manhole covers, tree branches etc.), and there should be at least 18″ access to all sides. We aim to complete installation within 10 working days from delivery of the greenhouse, however this may be longer during peak times.
