Trowel-Applied Cork — The Alternative to Thick Boards

Many Irish homes suffer from cold internal walls, condensation and mould — especially in older buildings or poorly insulated rooms.

Traditional solutions like insulated plasterboard can reduce room size, require major disruption, and create moisture risks if not detailed correctly.

VIPEQ Trowel-Applied Cork forms a thin, breathable thermal layer, improving wall surface temperature and comfort without bulky build-ups.

The System

What Is VIPEQ Trowel-Applied Cork?

VIPEQ Trowel-Applied Cork is a natural cork-based insulating coating applied by trowel directly onto internal walls.

Applied in thin layers (3–6mm)

Preserves room dimensions while improving comfort.

Breathable (vapour permeable)

Essential for traditional buildings — allows moisture movement.

Flexible and crack-resistant

Accommodates minor building movement and thermal expansion.

Internal use only

Designed specifically for protected interior wall surfaces.

Unlike board systems, trowel-applied cork follows the shape of the wall, preserves architectural details, and avoids major alterations to windows, skirting and fittings.

Core Uses

Where It Is Used in Irish Homes

Core Application

Cold External Walls

Improving wall surface temperature on north-facing rooms, external walls and exposed gables. Reduces the "cold wall feeling" and improves perceived warmth.

Condensation & Mould Prevention

By raising internal surface temperature, VIPEQ Thin Coat reduces condensation risk — particularly in bedrooms, corners and problem areas.

Solid Wall Buildings

Ideal for stone houses, solid wall homes and lime-rendered properties. Breathability is critical — VIPEQ allows moisture movement without trapping damp.

Retrofit Projects

Where thick insulation isn't practical — limited space, fixed windows, minimal disruption needed. Perfect for targeted improvements.

Window Reveals & Details

Performs where boards don't fit — window reveals, door surrounds, curved walls and tight spaces.

Conservation Works

Suitable for listed buildings and conservation areas where breathability and minimal intervention are essential.

Objection Handling

Why Trowel-Applied Cork Works (When Thick Isn't Practical)

While thin coat insulation does not replace the thickness of traditional insulation boards in U-value terms, it works differently and offers real-world solutions that thick boards cannot.

How It Works

Raises internal surface temperature
Reduces thermal bridging
Improves perceived warmth
Prevents condensation formation

Highly Effective For

Real-world comfort improvement
Problem walls in existing homes

What Our Customers Say

"The back bedroom was freezing in winter — external stone wall, old solid-wall build. We didn't want to lose room size with boards. The thin coat made a real difference to the wall temperature and no more condensation."

Brendan Lynch

Homeowner — Clare

"Tenants were complaining about mould in two rooms. We had the thin coat applied and it resolved the issue completely. The rooms are warmer and the wall surface temperature improved noticeably."

Mary O'Brien

Landlord — Kerry

"I've used VIPEQ Thin Coat on several heritage retrofit projects where breathability was non-negotiable. It's become my preferred solution for internal cold wall treatment on older properties."

Paul Kehoe
