Warmer, quieter and safer places with secondary glazing


In this new ebook, Selectaglaze examines how secondary glazing creates warmer environments, quieter places and safer surroundings

Founded in 1966, Selectaglaze is recognised as the UK’s leading specialist in secondary glazing and was granted a Royal Warrant in 2004. Its services include free technical advice and site visits, specification collaboration, assistance with listed building consent and aftercare guarantee.

Secondary glazing, a fully independent secondary system that retrofitted on the inside of an existing window, offers a number of benefits:

Warmer: Thermal upgrades reduce U-values and, in the long run, reduce energy bills.

Quieter: Reduced noise ingress and egress, making internal spaces quieter and preventing noise outbreaks that can disturb neighbours.

Safer: Provides additional security in its most basic form and higher levels against fire, blast and firearms attacks.

Sustainability: By refurbishing existing buildings, the embodied carbon in the existing windows is retained and the building remains fit for purpose for many more years.

The benefits

Thermal secondary glazing

The ebook examines each of these four areas, looking first at thermal secondary glazing and meeting the requirements for sustainable initiatives, including Building Regulations Approved Document Part L, Energy Performance Certificates, Passivhaus and EnerPHit certification for new and retrofitted buildings, and the WELL Building Standard.


It also discusses acoustic secondary glazing, looking at noise reduction and meeting regulations and requirements, such as World Health Organisation guidelines on acceptable noise levels, along with BS8233: Guidance on controlling noise affecting buildings and the Ministry of Housing, Communities & Local Government Noise Guidance first published in 2014 and updated in 2019.


On security, Selectaglaze, which is a longstanding member of Secured by Design, discusses secondary glazing’s performance in blast mitigation, ballistic attack and fire protection, with a case study looking at a Grade II listed refurbishment at Nottingham Castle.


Finally, Selectaglaze discusses how secondary glazing can contribute to the sustainability of a building, as well as end of life recyclability of its products and the company’s own wider sustainability commitments, which has seen it sign up to Planet Mark to undertake year-on-year carbon reductions.
