Goslin and Co can arrange for these testing procedures to be done by a specialist consultant where necessary as part of the design process.
Acoustic Testing Services
Testing will is now required to determine the sound insulation provided by the developer in respect of Building Regulations Approved Document E – Resistance to the Passage of Sound, Item E1.for new domestic development sites. This testing is required on a sampling basis for each development site and allows the developer to use similar details for additional premises once the principles have been established.

Air Leakage Testing
A compliance testing service for small, medium and large buildings using purpose designed equipment. The test equipment incorporates a flow grid measuring station to achieve highly accurate, repeatable test results to meet the requirements of CIBSE TM 23 which will satisfy the current requirements of Part L2 of the Building Regulations.
Testing can only be carried out once the building facades and the external envelope and internal finishes are completed. For the test, designed opening apertures including the doors, windows and other elements of the building envelope are closed as normal. Ventilation ducts and natural ventilation openings are temporarily sealed. Lift shaft ventilation openings are to remain unsealed.
Using a specialist infra-red camera can be used to determine the location of defective or omitted insulation elements within the building structure.
Since April 2002 Building Regulations 2000 Part L2 requires that a ‘Competent Person’ certifies that the building insulation is ‘reasonably continuous over the whole visible envelope’. This applies to all commercial and industrial buildings submitted for Building Regulations Approval after this date.
Thermographic surveys are normally only carried out once there is a temperature difference of 8-10�C between the internal space and the external elevation of the building. There must be reasonable access to all areas to be surveyed and the survey can not be undertaken if any of the building surfaces are wet.
Thermal imaging can also identify other potentially serious envelope defects such-as air leakage or water ingress into insulation elements
Although modern infrared cameras can measure heat emission and surface temperatures very precisely, infrared Thermography must be considered a qualitative tool and it is best to employ other methods to quantify heat losses from a building. Quantitative infrared surveys can only be conducted under very precise thermal and environmental conditions, which rarely if ever occur in the field.
