The Building Regulations in England and Wales set standards for most aspects of a buildings construction including air tightness, acoustic performance, fire safety, ventilation and electrical safety along with many other areas. The complete Building Regulations are split up into separate parts named part A to part P. The regulations regarding energy performance forms Part L of the regulations.
These regulations apply to nearly all new buildings and to many refurbished buildings. The regulations do not apply only to residential buildings; educational, commercial and industrial buildings are also included in the Building Regulations.
The aim of the regulations is to ensure that new developments are safer, more sustainable and more accessible than previously built. They also aim to make sure that buildings are built to a high standard, creating a comfortable environment to live, work or learn in.
Approved document L (Parts L1A, L1B, L2A, L2B) gives performance standards relating to the air permeability or air tightness of the building envelope within new and refurbished buildings. Part L1 applies to residential dwellings whilst Part L2 looks at all other types of building.
In order for a new building to be signed off by building control a number air pressure tests are required to be carried out by a suitably qualified engineer. The number of air tests required will depend on the specific requirements and the building layout. Building Control will often set the number of air tests required for a particular development.
The team at MACH Testing has the expertise and experience to carry out air tightness testing for any building in order to achieve building control sign off. We offer extremely competitive prices and can carry out jobs at very short notice nationwide.
We can also offer a highly competitive package providing both sound testing and air testing on 1 site visit. This reduces costs and reduces the number of sub contractors required thus increasing communication efficiency.
