Sectional garage doors rise vertically and split into several sections, made from thick insulated steel panels. This style of garage door is ideal for normal domestic-type garages.

Hormann and Garador amongst others offer great sectional garage doors in a range of sizes or with additional insulated fascia panels where required.

In most cases, it can be difficult to define a roller garage door as fully insulated, due to its construction. Roller doors are typically made with around 24 horizontal double-skinned slats, which all technically have a small gap between them to allow for flexibility.

However, there are real benefits to having an insulated roller door, like reducing energy costs by preventing heat loss, minimised noise levels and maintaining the integrity of temperature-controlled environments.

There are several factors that contribute to the level of insulation that can be expected from a roller garage door, like whether there are rubber or brush-type weather seals in the guides, a full hood cover for the roll, or how much overlap the door slats have to the side and the head.

When it comes to most wooden side hinged garage doors, they provide a good tight fit which offers good insulation value. Timber itself is a good insulator, depending on the type and thickness of the wood used.

Side hinged garage doors are a good option for any garage that is mainly being used as an active space such as a workshop, office, gym or playroom.

In most cases, optional insulation packs can be added with insulation boards to up and over doors. With these types of garage doors, the whole door panel has to move through the subframe when opening and closing, which means there is a gap all around the perimeter. Underneath the door can be insulated better with weather seals and door stops.
