Slim Cavity Units for Portsmouth properties
Half the Slim Cavity Units problems we fix in Portsmouth started as a sizing assumption. Around here it is naval-era terraces, New Forest timber-framed cottages and 1960s coastal estates, and that alone rules out anything bought by the pallet. With high wind-driven rain off the Solent in the mix, water ingress at head and jamb on exposed south-west elevations is a question of when rather than whether. Everything we do here comes back to narrow cavities that perform while keeping the sightline historic.
We would rather spend an hour surveying than a week correcting. Tell us the problem rather than the solution and we will advise on both.
Something particular to this area: conservation stock in Winchester and Lymington usually requires slim-profile glazing.
