About the series

Last year, The Green Register launched our new qualification Retrofit Skills Level 2, a hybrid qualification providing foundational training for individuals and businesses looking to move into retrofit construction. We're excited to open up the practical modules for anyone to attend, providing hands-on experience to a range of skills crucial to retrofit construction. 

These sessions can be attended as stand-alone events, or book onto the full series to receive a 10% discount. If you want to book onto Retrofit Skills after attending one of the practical modules, you can claim back the event rates from your Retrofit Skills registration fee! Can't make this date? We're running the same workshop in July. 

About the event

Jonathan Preston – builder and trainer, will use his experience and knowledge of the practical applications of building physics principles and materials to lead a practical session where you will get to grips with different types of insulation and air-tightness tapes suitable for domestic retrofit.  

Insulation is one of the three core principles of retrofit, alongside insulation and ventilation; and understanding these issues present in most UK homes and how to go about addressing them are key to successful retrofit.  

The training will explore the principle of fabric first, how airtightness can contribute to insulation, and selecting appropriate insulation and airtightness materials, and their practical applications.  

You will have the opportunity to work with other learners to cut insulation to fit timber frames construction, to apply airtightness tape around protrusions through building fabric, and to witness the result of a thermal insulation and airtightness experiment. 

The trainer and host The Green Register will be on hand to answer questions and discuss the issues throughout, so you will leave well informed to tackle your next retrofit project.
