About Heat Loss

What is meant by a ‘warm’ office?

A tin hut in the midst of a Siberian winter could be considered ‘warm’ if adequately heated but it could not be considered ‘efficient’. Once the heat source was turned off it would lose heat very rapidly.

Timber is not a good insulator and timber log cabins can only be considered ‘warm’ just so long as sufficient heat is applied to balance the heat loss and this can be considerable!

When we at Garden Offices UK refer to our buildings as warm we mean one that requires very little heat to balance the heat loss. This is achieved by fantastic insulation in floor, walls and roof. In this type of building the heat given off by the occupants, lighting and computer equipment make a significant contribution.

You will find that out smaller offices, once up to a comfortable temperature, can be heated just by the lighting and computer equipment even in the depths of winter. That is what WE call warm.

It is important to make the distinction because by putting an office in your back garden you will have six surfaces to heat from and it is therefore important to choose an office which will keep this heat loss to a minimum both for the sake of the environment and your pocket.

What does insulation in garden offices really do?

Thermal insulation resists the flow of heat. It slows the passage of heat. Heat is a form of energy. It always travels from hot to cold – flowing to the outside during winter and to the inside in summer. By reducing the heat flow, a properly insulated office uses less energy than a poorly insulated one.

Why do we consider that garden buildings built from SIPs are better insulated than those which are built from other materials?

Our garden buildings being constructed from SIPs have a virtually continuous envelope of 100 mm insulation in floors, walls and roof.

Compare a building constructed from SIPs with a traditionally constructed timber framed building. Traditional timber frame are inferior for the following reasons:
