The Retrofit Workshop: Service Penetrations & Junctions - Airtight Sealing is designed for professionals involved in retrofit, construction, housing, and building maintenance who want to develop practical knowledge of airtightness measures within existing buildings. Service penetrations and building junctions are among the most common sources of uncontrolled air leakage, leading to heat loss, reduced energy efficiency, increased energy costs, and occupant discomfort. This hands-on workshop provides practical guidance on identifying leakage points and implementing effective airtight sealing techniques to improve building performance and support successful retrofit outcomes.
Course units
The workshop covers the principles of airtightness, identification of air leakage pathways, sealing methods for service penetrations, treatment of building junctions, moisture management, condensation risks, materials and products used for airtight sealing, quality assurance, and retrofit best practice. Learners will gain practical insight into delivering effective airtightness improvements that contribute to enhanced energy efficiency, occupant comfort, and building performance.
What next?
Successful learners can progress to further retrofit, energy efficiency, and low-carbon technology training, including Retrofit Advisor, Domestic Energy Assessment, Domestic Ventilation Systems, Heat Pumps, and other sustainability-focused programmes. The workshop also supports those involved in PAS 2035 retrofit projects and domestic energy improvement schemes.
Entry criteria
There are no formal entry requirements for this workshop. It is suitable for retrofit professionals, builders, installers, tradespeople, housing professionals, maintenance personnel, and anyone involved in energy efficiency improvement works within domestic properties.
