Alumaflex Reducing Energy Costs

Alumaflex Thermal insulation is specified to control three components of heat transmit­tance through the building fabric:

• Conduction of heat through building fabric.
• Convection via air movement.
• Radiant transmis­sion.

Criteria for specifying Alumaflex thermal insulation.

• Performance in use and longevity – full product certi­fica­tion
• Buildability and the reassurance that on-site work will meet the required thermal design standards.
• Will the insulation have minimal impact on building design and capital cost.

Performance in use and longevity: BBA certi­fica­tion

• Alumaflex provides Stability and meets the expected effective life performance.
• All U-values are achieved in practice using Building Regulations / BRE guidance.
• Alumaflex has undergone stringent ageing tests carried out by the BBA which is the basis of calculations in the design performance.
• Alumaflex is not vulnerable to factors affecting performance including moisture and vermin attack.

Buildability – Consi­dera­tion should be given to the following design issues when considering insulation materials:

• Detailing required to achieve thermal integrity, including avoidance of cold bridges, air-flow paths, oppor­tuni­ties for settlement or compression of fill and other movement during and after construc­tion.
• Ease of working around complex details on site.
• Health and safety consi­dera­tions for the installer.
• Ease of testing.
• Do the materials meet the necessary test criteria under the Building regulations.
• Requirements for vapour and radiant barriers to maintain performance.
• Ability to undertake additional work without significant disturbance to the insulation materials.

Alumaflex: Impact on building design

• The insulation material and effect on floors and external wall thickness are minimal.
• Multi-Foil Insulation provides the opportunity to incorporate the insulation into other aspects of building function; for example, creating thermal benefits in limited spaces eg. the use of a roof void as a habitable space.
• Alumaflex provides significant thermal benefit with a low level of capital cost.
