A greenhouse is a hugely practical addition to any garden - especially over the colder, frostier months. This glass house can provide much-needed protection for tender plants and bulbs and keep them out of freezing temperatures. But is it worth insulating a greenhouse?

Although there are many greenhouse ideas out there, the reality is that greenhouses are often made entirely from single-pane glass, which doesn’t offer much in the way of insulation. And while greenhouses can offer a barrier from the wind and rain, the cold temperatures can still make their way inside and ruin your garden in the process.
