We chose the popular greenhouse with toughened glass 6x8’. The framework was easy to erect but putting the window sills (after detangling them) was time consuming, it would be easier if this job was done in the factory! We ordered the Louvre window as an extra, this did not seem as good quality as the greenhouse! The frame was thin and the part that you ‘pinch’ to stop the glass falling out was inadequate, in fact it broke and customer services sent another frame! This time we’ve used silicon sealer to keep the glass in place! The roof vent window is working well with the varying temperatures! Overall we are pleased with our greenhouse & is now full of plants!
