British Board of Agrément

The BBA is the UK's major approval body for new construction products and installers. Its Agrément Certificates are recognised by specifiers and other industry decision-makers as proof that the products covered by them have been rigorously and impartially assessed, that they will allow compliance with Building Regulations and will last, in their opinion, for a defined period.

In this last element, the provision of durability statements, the BBA are probably one of the most experienced organisations in Europe. Based on extensive internal testing and validation of product performance in application, the BBA will make a statement as to how long they believe a product should perform in use.

The BBA stated, in their opinion, life expectancy for Sarnafil PVC membranes is “in excess of 40 years” when used in conjunction with a planned maintenance cycle and regular inspections.

It prescribes controls for those activities which have an affect on the environment, activities such as the use of natural resources, handling and treatment of waste and energy consumption.

Other elements of the environmental management system include environmental policy, planning, implementation and operation, checking, and management review to ensure the continual improvement of the environmental management system.

Building Regulations Affecting Roofs

The benefit of these changes will be a reduction in the energy used to heat your home, which in turn will reduce the carbon footprint of your home. However to achieve this you will have to invest in the installation of adequate thermal insulation beneath the waterproofing membrane, in order to achieve the requirements set out in the Approved Documents.
