Virtual Breathable Internal Wall Insulation Systems for Single Leaf Masonry Walls

In this CPD we will discuss the impact of moisture on solid stone/brick walls, considering the causes of moisture ingress and how walls function before and after applying insulation. We will cover the necessity of moisture management in solid masonry walls and the importance of using diffusion open materials.  We will use case studies to share best practice examples of various solid masonry wall insulation systems using breathable materials to ensure building structural safety and longevity.

Request CPD at a date that is convenient for you and your team.

Ideal for

  • Architects
  • Specifiers
  • Building Surveyors
  • Contractors
  • Consultants (Energy, Passivhaus)
  • Historic/Listed Building Consultants
  • Damp Specialists
  • Students
  • Anyone interested in sustainable, energy efficient building

Key learning

  • Reduce heat loss without condensation risk
  • Eliminate thermal bridges at key junctions
  • The impact of moisture on solid walls
  • Primary drivers of moisture ingress
  • Moisture control in solid masonry walls
  • Importance of diffusion open materials
  • Options for internal insulation of solid walls
  • Using compatible paints and finishes


Description

Who it is for

This training is aimed at professionals from all disciplines of the building design and construction industry who are interested in the management of moisture in buildings with masonry walls and are looking for robust breathable internal wall insulation solutions.

What you learn 

Modern cavity wall buildings are usually insulated within the cavity, however, in the UK 28% (approximately 7 million) houses have solid wall construction where cavity insulation isn’t a solution for thermal upgrade.

External wall insulation could be an option, however it is not always preferable or permissible, either because it inevitable changes the external appearance of the building or because of regulatory restrictions (e.g. listed buildings).

Internal wall insulation is more difficult and sometimes more expensive to apply, however, the thermal comfort, potential energy savings and moisture regulation make it worthwhile.  It can incorporate risks and may create more problems than benefits if not well-thought-out and designed appropriately.

In this CPD we will discuss all the parameters to be considered when specifying internal wall insulation, including:

The importance of taking into account the local climate and the primary drivers of moisture ingress when considering thermal solutions for solid masonry walls.

The impact on internal air quality and the need for ventilation.

Thermal imaging comparison and consequences of uninsulated and insulated internal walls.

The importance of vapour permeable materials to ensure building structural safety, longevity and internal/external wall aesthetics.

Different approaches to moisture control in solid masonry walls and minimising risk factors with the help of Hygrothermal Modelling (WUFi).

How to avoid thermal bridges at critical junctions.

A range of internal wall insulation systems suitable for single leaf masonry walls using diffusion open solutions including:

  • Semi rigid natural insulation between stud partition with internal Intelligent vapour control system
  • Directly rendered natural insulation system 
  • Mineral based capillary active insulation systems

Examples of best practice solutions will be shared through a range of case studies.

What you will do?

You will receive industry leading training from a highly experienced technical professional.  We actively encourage you to share details and drawings in advance of a suitable project so that it can be included in the presentation, making the session as relevant as possible for all involved.  We will bring product samples for you to see and there will be the opportunity to ask questions.  

What happens on the day?

We will generally arrive at your offices around 30 minutes before the CPD starts to set up.  A dedicated meeting room with projector/screen would be helpful, although not essential, and we will bring a laptop to present from.  The presentation will start at the time you have chosen and generally last around an hour.  Following the CPD, we can arrange for our technical professional to meet with you to discuss specific projects, review drawings and make recommendations etc.  Please let us know in advance if you would like this additional free service.

 What you will gain from attending this CPD

  • the impact of moisture on stolid stone and brick walls
  • how project specifics impact on moisture management strategies
  • the need to improved breathability of conventional approach
  • solutions for breathable internal wall insulation

Points Gained

This CPD is a 1 hour stand-alone CPD providing 1 point towards maintaining your professional standard.  This can be doubled with an additional 1-2 hour related activity.

Sustainable architecture is a rapidly developing area and is a RIBA core curriculum topic.  There is a requirement for a minimum of 2 hours to be spent on each of the core 10 topics.

Continued Development 

The content of this CPD is great background knowledge for sustainable, energy efficient retrofits, particularly with heritage buildings.  Our other CPDs develop these concepts for different types of insulation and building methods.  

We have a dedicated Training Area at our UK office in Cumbria and our Ecological Centre of Knowledge in Co Meath in Ireland,   where we have examples of all the systems covered in this CPD and run regular training providing attendees with the opportunity to see and try the different solutions first-hand.

We periodically present thorughout the UK and Ireland focusing on ‘How to internally insulate solid stone and brick walls’ and provide demos at various shows and regional training events.

We regularly do on-site training, toolbox talks etc with all key stakeholders and trades involved in specific projects.

Agenda

  • The impact of moisture on solid walls
  • Primary drivers of moisture ingress
  • Building physics and how the wall functions before and after applying insulation
  • The necessity of moisture management
  • The importance of using diffusion open materials to ensure structural safety and longevity
  • Insulation options including what to avoid and why
