Straight Answers About Cork Insulation

AeroCork is a cork-based coating applied in thin trowelled layers to suitable walls. It is vapour permeable and designed to improve surface comfort with little loss of room space.

A common specification uses two cork coats totalling approximately 3–6mm, plus the compatible finish. The wall condition and selected system determine the final build-up.

No. It can help reduce cold-surface condensation risk by improving surface temperature, but leaks, penetrating damp, rising damp, ventilation and heating must be considered separately.

Its breathability can make it useful on suitable older solid-wall properties, but the existing background and moisture condition must be assessed first.

Not in performance terms. It is a much thinner, less intrusive option with different strengths, particularly where losing room depth is undesirable.

Often, yes, if that is the appropriate scope after assessment. Junctions and neighbouring cold areas need consideration so the treatment does not simply move the problem.

A trowelled system can follow narrow reveals, curves and awkward bay details. We assess every surface before deciding where the system should continue.

A thin, flexible and breathable cork-based exterior finish for suitable prepared render, brick or masonry. It is not described as equivalent to thick external wall insulation.
