Our approach

Property-specific advice before specification

Older Bath homes need careful decisions. A cold wall may be suffering from surface condensation, but it may also have a leak, defective exterior finish or another issue that insulation should not hide.

We start with the construction, condition and moisture pattern. If a thin breathable cork system is appropriate, we explain the build-up, preparation and finish. If another defect needs attention first, we say so.

Specialist focus

Internal AeroCork leads what we do

Most enquiries concern cold solid walls, condensation-prone bedrooms, cold bays and rooms that never feel comfortable. CosyCork combines wall preparation, cork application and high-quality finishing so the treated wall is considered as one complete job.
