The Knee-wall sunroom is the kind of room that is constructed with walls constructed halfway. It is a room that is constructed with the stone wall from the foundation to halfway. The lower part of the wall is built with stone, blocks, and stone. The most recommended length is at the level of the window sill. Some prefer that the level is lower than the window sill. From the stone upwards is the glass up to the roof level. The glasses are of wider length and width throughout the whole wall. This can light up the whole room naturally thus minimize the electricity bill.
This is the kind of patios that is constructed as an extension made of mesh. The walls are made of mesh. It can allow fresh air into the room, and there is proper air circulation throughout the whole room. It is a common type of room that is preferred by many because it is more economical. This is because the mesh is not as costly as the glass for the wall. However, this room is not functional at all times. When it is cold, it can be very uncomfortable since it cannot maintain heat. In case there is the strong wind blowing towards the sunroom the people inside can feel a lot of discomfort. However, during warm and hot weather the room is more usable and comfortable to the users. This makes it a seasonal room that can be used only at times but not all the time.

These are done to be useful during the spring only. During the summer time, they are not in use. They are made not to be heated or air-conditioned. Therefore they are economical since they do not need the extra control of temperature. The room is used when the weather is convenient.
The patio covers can also be referred to as the solarium type of room. One cannot construct this type without a full permit. This type has the walls fully encased with glass from top to bottom. Unlike the seasonal ones, they are operational all round. One can heat them to the required temperatures as per the need. They can be heated when it is cold and when it is hot, the air can be cooled by the use of an air conditioner. They are more luxurious and can be used at any time of the day all-round the year.
