What are the key points I need to know about TGD-E?Regulation E1
aims to ensure that dwellings achieve reasonable levels of sound insulation from sound transmission emanating from attached buildings or differently occupied parts of the same building.Regulation E2
aims to protect dwelling occupants from noise produced from reverberation in common internal areas which provide direct access to a dwelling or dwellings.These Regulations also amend Article 13 of the Building Regulations 1997 to require Part E to apply to an existing building or part of a building which undergoes a material change of use to a dwelling. The amendments to Part E of the Building Regulations and the associated technical guidance meet the overall objective of securing reasonable standards of health and safety for persons in or about buildings in respect of the passage of sound. The operative date of the Regulations is 1 July 2015
.What is the law on sound insulation testing?
Technical guidance document Part E (2014) of the Building Regulations 1997 (S.I.
no. 497 of 1997) relates to the mitigation of sound transfer between dwellings and
rooms within a building. The regulations simply state that walls and floors must have
“reasonable resistance” to airborne and impact sound. No consideration is given to the
nature or location of the building or potential noise sources.Our test services come under the ‘Ancillary Certification, Part E – Sound Building Control (Amended) Regulations 2014’What are ‘Ancillary Certificates’ and who is an ‘Ancillary Certifier’?“Ancillary Certificates”
means a certificate other than a statutory certificate of compliance as prescribed in the Building Control Regulations given by a competent person to confirm compliance of elements of the building, design or works with Building Regulations;“Ancillary Certifier”

. These are an integral part of the Building Control Regulations 2014 February 2014.What standards do ICAN Acoustics use when carrying out a sound insulation test?
On-site testing is carried out using:
- EN ISO 16283-1 :2014 Field measurement of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation.
- EN ISO 16283-2 :2015 Field Measurement of Impact Sound Insulation of Floors — Part 2: Impact sound insulation.
