  • Thermal Imaging

    Use of an infrared camera to identify heat loss, missing insulation, cold spots and thermal bridges.

  • Thermal Envelope

    The parts of the building that separate heated spaces from unheated spaces or outside air.

  • Thermal Conductivity

    How easily heat passes through a material. Lower conductivity means better insulation performance.

  • Thermal Bridge

    An area where heat passes through the building fabric more easily, often at junctions, steelwork, lintels or gaps in insulation.

  • System Boiler

    A boiler that works with a hot water cylinder but has many components built into the boiler unit.

  • Suspended Timber Floor

    A timber floor with a ventilated void underneath. It can often be insulated between the joists.

  • Specification

    The written technical detail describing how retrofit measures should be installed.

  • Space Heating

    Heating used to warm the rooms in a home.

  • Solid Wall

    A wall without a cavity, often found in older homes. Solid walls can be insulated internally or externally.

  • Solid Floor Insulation
