Door refurbishment


Energy and moisture

The purpose of doors has somewhat been forgotten.

The functionality could be perceived as purely a practical consideration, however, learning instinctively when to operate the door is more likely to be in response to an emotional need. Either the occupants need for comfort and modesty or the emotional needs of the property. Perhaps the need to increase air exchange with cross-ventilation or the need to reduce internal convection currents that convey moisture; resulting in energy loss and degradation.

Operable internal doors. Convection currents, Thermodynamics.

We’ll be working alongside experienced practitioners, learning how to design and plan, as well as the practical delivery.

We’ll consider the underlying objectives of the installation within the broader context of energy and moisture in the home.

We’ll look at the preparations that are required to the doors and how these affect the quality and speed of the installation.
