Event Description

Do you want to learn:

  • how to achieve stringent airtight standards in retrofits?
  • which is the best way of insulating an external wall - inside, outside or the bit in between?
  • how the design team and builders can effectively communicate to achieve best practice detailing?
  • what happens to moisture movement when adding wall or roof insulation?

Architects and builders sometimes have an uneasy relationship on site - both think they know best when it comes to detailing!

Achieving best practice for new buildings can be a straightforward process but when it comes to effective detailing for refurbishments - especially when aiming for well insulated, airtight and breathable solutions using low impact building materials - the outcome is sometimes less than satisfactory. This is due to many factors including existing conditions but more often than not it is a lack of communication between the architect/designer and the builder/contractor.

This cutting edge seminar offers delegates an opportunity to learn how to achieve best practice ‘green’ detailing on site from a wide range of experienced practitioners such as a builder, an architect and technical experts together with some academic research.

The presentations will include live demonstrations using full size construction mock ups to illustrate how to achieve very stringent airtightness standards and the installation of insulation and various membranes and will cover examples of difficult detailing such as at roof hips and valleys, dormers, window and door reveals. There will also be videos of
site practices that actually work, technical information on tried and tested building products and a presentation of research that compares internal, external and cavity wall insulation for retrofits and avoiding interstitial condensation.

Also addressed will be the thorny issue of the cost to install low impact building materials, hidden costs like wastage and storage, delays if products need to be reordered and how builders save money compromising on quality or using substitutes.

What did the delegates say about previous events on the same topic?

“Very good, very switched on, alive and useful from beginning to end”

“Extremely interesting presentation, and great to hear from a contractor so concerned about sustainable construction. His suggestions as to an architect’s approach to specifications and site visits were particularly useful.”

“Very useful, focused and relevant – I learnt a lot”

“All useful. I appreciated the speaker’s enthusiasm and the work done in preparing for the talk – impressive!”
