The foundations of a winter garden are strictly recommended to be discussed with your winter garden supplier.
Various types of gardens, either plastic, aluminium, wood, or combined aluminium wood use different types of profiles and glass compositions ... the weight of the winter garden itself depends on these properties. Moreover, in winter, the cold coming from the floor is very unpleasant, therefore a winter garden without proper fundaments loses its key purpose, especially in winter. And the point is, that the winter garden should be habitable especially in winter! Our recommendation is to prepare the foundations and the base plate similar to a condition of a family house. The weight of the structure and glass at the dimensions of about 20 m2 is from 1.5 to 1.8 t. It is simply appropriate to have a sufficiently strong foundation to prevent the glass from cracking.
