8 x 18 Alton Harrow - Victorian Glass To Ground 8ft Wide Cedar Greenhouse

Alton have been at the forefront of the Cedar greenhouse market since 1921. With their vast knowledge and experience, along with years of customer feedback, they have designed and created a Cedar greenhouse fit for the 21st Century; it is called the Alton Evolution ...

The Alton Evolution has been designed to be stronger. It is surprising how some greenhouses both aluminium and Cedar have become thinner over the years to save cost. The Evolution however uses thick glazing bars based on 44 x 44mm timbers or in places 44 x 69mm.

Most wooden greenhouses have glass held in place by a beading or a groove, this can result in the glass 'rattling' in the frame; The Evolution has developed a bar capping system that uses the toughened glass as an integral part of the overall strength of the greenhouse by gripping it tightly. When you feel the greenhouse, there is little or no movement in it and you can see that it is far stronger (and you don't get a rattling sound from the glass).

The cleverly designed jointing system has a duel benefit of making assembly straight forward and adding strength to the framework. The Evolution greenhouses are supplied as standard with large panes of 3mm Toughened safety glass that help with the rigidity of the overall structure. Toughened glass is 5 - 7 times stronger than standard horticultural glass and if it is broken it will disintegrate into hundreds of small pieces (like the side window of a car) - greatly reducing the chances of injury.
