The garden Mini Greenhouse has ledged braced doors, 12mm pressure treated shiplap tongue grove cladding and 28mm x 44mm planed rounded framing. This Greenhouse comes with Solid OSB Floor and Roof and mineral roofing felt and full fixing kit and instructions. Construction The Greenhouse is constructed from high quality pressure treated tongue and groove shiplap cladding. The high quality floor joists give the shed a solid and sturdy feel. The floor and roof is constructed from 10mm solid OSB Board. Top grade timber is used throughout, sourced exclusively from Scandinavia where the best timber for sheds is produced. The timber is tight grained producing less sap and is therefore a more durable timber than the faster growing timber used by other shed manufacturers. The benefit of purchasing a pressure treated building is that it is almost completely maintenance free once the building has been soundly erected, meaning there is no need to treat it every year which provides great savings
