Event series: "A fabric first approach to healthier more energy efficient new and existing buildings."
ES1: How to Internally Insulate Solid Stone and Brick Walls: 13th March 2024, 09.00 - 11.00
ES2: Roofs, External Walls and Floors: 20th March 2024, 09.00 - 12.30
ES3: Achieving Airtightness: 27th March 2024, 09.00 - 12.00

One of our most popular seminars offering solutions when retrofitting roofs, external walls and floors. Working with the existing fabric, traditional building materials and older methods of construction, refurbishing homes can often be as challenging as new build projects.

It requires extremely careful consideration of any intervention so that the work results in an improved building thermal performance without creating issues such as damp, mould and interstitial condensation.

The speakers from Green Register partners Ecological Building Systems are experts in the field of sustainable solutions that enhance rather than harm existing buildings.

They will set out the problems with inappropriate interventions, for example, the use of non-moisture vapour diffusion open materials and unvented air gaps behind insulation, followed by a series of sustainable solutions based on the in-depth experience gained over decades of work in this field.

Delegates will learn about the various options available for refurbishing lofts, floors and ‘difficult to treat’ external solid stone and brick walls using natural insulations and products that are compatible, durable and relevant to our climate in the UK.

The presenters will be available for advice on individual projects both within the seminar and on an ongoing basis.
