Retrofitting Internal Wall Insulation - Bristol

 Registration is closed for this event

Retrofitting internal wall insulation - a solution or a problem waiting to appear?

  • What are the condensation risks associated with internal wall insulation (IWI)?
  • How can we avoid building in problems for the future such as interstitial condensation?
  • Which is better - natural or synthetic wall insulation?
  • What are the options with solid wall buildings in conservation areas?

Join us to investigate these questions and:
- explore both the theory and practical aspects of improving our existing buildings
- with live demos and practice of installing various insulation materials

With much of the activity in the construction industry focusing on improving the performance of existing buildings and encouraging the retrofitting of wall insulation (both internal and external), questions are now being asked as to the effectiveness of this approach.

This one-day seminar, is split into a morning of theory and an afternoon of practical workshops, allowing delegates a hands-on experience of IWI installation.

After a brief introduction by Green Register director Lucy Pedler who will identify some of the potential problems with IWI installation on existing buildings, Lucy will then present the options for IWI materials – both natural and synthetic and discuss the pros and cons of both types of insulation.  Niall Crosson of Ecological Building Systems will explain the building physics of moisture movement in buildings. Understanding these principles is essential before making any decisions about what measure to take when considering retrofitting wall insulation.

After the break, sessions will continue presenting further IWI options. Kate Watson will give details of Bristol City Council’s response to the roll out of internal wall insulation, and Michael Hunter of Isover and Matthew Wellesley Smith of NBT will share case studies. 

Two practical demonstrations follow in the afternoon from Kevin Hook of Isover and Matthew Wellesley Smith of NBT. Delegates then get a chance to try out the products themselves with instruction from the speakers.

What have our delegates said about the Retrofitting IWI seminars?

“A great combination of information from basics to detailed application!  A very useful overview and introduction”

“Excellent introduction to very interesting materials”

“A great understanding and awareness of materials, with its applications and advantages”

“Thank you for yet again organising a superbly interesting and informative day yesterday ... We regularly attend (as one must) many CPD courses organised by other organisations, and except for the rare one, the Green Register CPDs are far superior to the others.”
Dr Judith J Perry, MCIAT Director, Sohnius & Perry Ltd
