High Quality Aluminium Frame - Janssens’ frames are constructed from a specialist tubular aluminium profile section. This tubular section design makes for an extremely sturdy, weather-proof structure in many designs, including much larger greenhouses and orangeries.
Stainless Steel Fittings - All fittings, nuts and bolts used in the construction of Janssens Greenhouses are stainless steel. No rust, rot and they look so much better than cheaper alternatives used by lesser brands.
13 Year Warranty - Have total peace of mind and confidence in Janssens, with the longest product warranty in the industry. Covers aluminium frame structure.
4mm Toughened Safety Glass - Janssens use only full length 4mm Toughened Glazing on their glass greenhouses. It’s around 6 times stronger than normal glass and much more durable. You won’t find any cheap looking overlapping panes or the more common, thinner 3mm glass here.
10mm Polycarbonate Glazing Option - You may be buying your greenhouse for a local authority, government, allotment or school, where for health and safety reasons, only polycarbonate glazing may be used. If this is the case, you may order your new greenhouse with 10mm twin wall polycarbonate. This material is very safe, impact resistant and offers excellent shading for your plants during very sunny, hot weather.
However, if you are situated in a particularly windy position we would always advise that you select 4mm toughened glass for your greenhouse as it offers far superior wind resistance to polycarbonate.
