The Insulation Crisis in Homes – The Hidden Problems in Retrofit – Episode #21
No Fluff. Just Real Industry Conversations
Are we improving the performance of our homes… or creating problems we don’t yet fully understand?
In this episode of The Hard Hat Talks, Kenneth Martin sits down with Wilson and Karen Shaw of ‘BCA Insulation’ to explore the real challenges behind insulation, retrofit, and upgrading the UK’s existing housing stock. Drawing on over two decades of hands-on experience, they unpack how well-intentioned schemes, evolving standards, and changing installation practices have shaped today’s industry—and why some past solutions are now being reversed.
From traditional Scottish buildings to modern retrofit frameworks, this conversation highlights the growing complexity of improving energy performance without compromising building health. A grounded, practical discussion for architects, developers, and contractors looking to better understand the balance between efficiency, compliance, and long-term performance.
