| 01250 872 261 Technology You Can Rely On From A Brand You Can Trust HAMM Principles For any building to have an energy efficient, healthy, moisture free building envelope there is a clear need to manage the balance of Heat, Air and Moisture movement (HAMM) throughout the building’s life cycle from design, construction, completion and use. Understanding the importance of these key elements on the building envelope is crucial to the successful construction and operation of a building. Architects, designers, and building product manufacturers must seek to ensure that they fully understand the science behind our buildings, managing the external and internal forces which impact on the quality of the completed building, its performance in use, as well as the health of it’s occupants and the wider environment. The A. Proctor Group Ltd, a family owned company in its fourth generation, has been providing solutions and products to the construction industry for over 50 years. They have been developing vapour permeable membranes and vapour control layers for over 25 years, and can provide condensation control and air barrier solutions for all areas of the building envelope, across a variety of projects.
