Regulations
Attention to detail in the specification of any building envelope will pay dividends in the long-term performance of that building. The primary areas of performance are driven through the Building Regulations, so it is important to understand what the Regulations mean and how to achieve compliance.
Pulling together the final specification requires consideration of all the issues highlighted, together with the detailing of how they fit together and the specification of the necessary ancillary components that complete the system.
Air-tightness
The aim of the air-tightness requirement is to minimise uncontrolled air infiltration, but with sufficient controllable ventilation to allow fresh air to maintain good internal operating conditions.
Fire Performance
Two major considerations for fire performance are compliance with the Building Regulations and insurance requirements. These are not necessarily the same.
Acoustic Performance
Noise and its control are important aspects of building design. Whilst Building Regulations in this area focus on the transmission of noise between separating wall and floor constructions and not the external shell, the building envelope can play a key role in keeping internal noise in or external noise out.
Thermal Performance
Environmental concerns and the rising cost of fuel mean that there is an increased focus on the minimisation of energy use during the natural occupational life of a building. The thermal performance of the building envelope can make a significant contribution to reducing the overall building energy usage.
Structural Performance
Corus is a company committed to providing the very best pre-finished steel products for use in roof and wall cladding systems. These systems rely upon the structural integrity of the profile shape and the stability and interaction with other structural components to ensure fitness for purpose when subject to external forces.
CE Marking
The Construction Products Directive (CPD) is a European Directive that seeks to remove barriers to trade. The CPD introduces the concept of CE marking for all construction products and profiled steel roofing and cladding products fall within the directive.
