Thermal Corkspray — Ireland
A breathable thermal cork coating designed for Ireland's damp climate, older buildings, cracked render, condensation-prone surfaces and modern retrofit projects.
Ireland's climate creates ongoing problems for buildings — wind-driven rain, exposed façades, cold internal surfaces, condensation, mould risk and cracking external finishes. VIPEQ Thermal Corkspray is designed to help protect and improve buildings with a thin, flexible, breathable coating that supports thermal comfort and long-term façade performance.
For traditional construction, official Irish guidance stresses that materials used on traditional walls should be vapour-permeable to avoid condensation problems within the wall build-up. VIPEQ Thermal Corkspray is naturally vapour-open — making it particularly relevant for older Irish housing stock.


Cork is one of the world's most sustainable natural materials and one of the most eco-friendly roofing and insulation solutions available in Ireland today. The bark is carefully stripped by hand from living cork oak trees — a tradition unchanged for centuries. The tree is never cut down; it regenerates and can be harvested again every nine years.
Portugal's cork forests are among the most biodiverse ecosystems in Europe. Choosing VIPEQ means choosing a material that is renewable, biodegradable, and carbon-storing — a genuinely sustainable roofing solution without compromising on performance.

Weather protection and breathable thermal barrier for rendered, masonry and painted exteriors exposed to Irish rain and coastal conditions.
For bedrooms, north-facing rooms and solid-wall homes where cold surfaces, condensation and recurring mould are a problem.
Useful below cold roof spaces or rooms prone to surface condensation and thermal discomfort.
Ideal for stone, lime and solid-wall construction where breathability and reduced build-up are essential to protecting the fabric.
Covers window reveals, door surrounds, curved walls and bay windows where rigid board systems are impractical.
Flexible coating that bridges minor movement cracks and refreshes weathered, patchy or failing facades.
Offices, retail, schools, care settings and public buildings where minimal disruption and practical upgrading matter.
Where thick insulation is not practical — eaves restrictions, listed details or partial upgrade situations.

Irish traditional walls — stone, solid masonry, lime-based construction — behave differently from modern cavity walls. Inappropriate interventions can create serious moisture-related problems within the wall fabric. VIPEQ Thermal Corkspray is naturally vapour-permeable, making it suited to projects where breathability, reduced build-up, and retention of architectural detail matter.
Always discuss heritage or listed projects with your architect or conservation professional.
By creating a thermal barrier on the surface, VIPEQ Thermal Corkspray helps raise the internal wall temperature — reducing the cold surface conditions that allow condensation to form. It does not solve all damp issues, but it is a practical tool for addressing cold-surface condensation risk as part of a properly considered approach.
Damp and mould in rented homes is a recognised housing issue in Ireland. Minimum standards for rented accommodation require properties to be free from damp. Improving surface thermal performance is one practical step.
Target Spaces

VIPEQ Thermal Corkspray is not just decorative. It is a flexible protective coating that bridges minor surface movement, protects against further deterioration, and provides a renewed, modern finish — all in one application.
Where thick external insulation is not practical — eaves restrictions, awkward details, partial upgrades — VIPEQ Thermal Corkspray offers a breathable, lower-build-up alternative that still delivers real thermal and protective benefit.
Improving comfort on lightweight structures that suffer from temperature swings and condensation.
Useful where internal condensation is a problem on metal surfaces.
Cold spots, thermal bridging areas and awkward room layouts.
Comfort and condensation control in buildings not heated consistently.
Selected semi-conditioned spaces where surface protection and thermal moderation are beneficial.
This product suits clients looking for a thinner, more breathable and more versatile solution than conventional insulation systems, in the right application.
Vapour-permeable by nature — critical for Irish traditional buildings.
Raises surface temperature, reducing cold spots and improving comfort.
Natural cork absorbs building movement without cracking.
Far less build-up than conventional board insulation systems.
Warmer surfaces create fewer conditions for moisture to settle.
Goes where rigid boards cannot — bay windows, curves, junctions.
Practical and aesthetic — one coating does both jobs.
Renewable material with a strong sustainability profile.
Maintains more original building character than bulky systems.
Tested for wind-driven rain, coastal exposure and damp climates.
The Problems
The VIPEQ Solution
High rainfall, wind-driven rain, coastal exposure and older solid-wall housing stock create challenges that generic European products do not fully address. VIPEQ Thermal Corkspray offers a practical option for projects where breathability, flexibility and low build-up are important — especially where full external insulation is not viable.

VIPEQ coatings are made from natural cork — harvested sustainably from cork oak trees in Portugal and Spain. The bark is carefully stripped by hand every 9 to 12 years without harming the tree, which lives for over 200 years and continues to absorb CO₂ throughout its life.
This makes cork one of the most sustainable insulation materials available — renewable, biodegradable and with a low carbon footprint from source to application.
"We had persistent condensation and mould on the north-facing bedroom wall for years. After VIPEQ Thermal Corkspray was applied, the wall stays noticeably warmer and we haven't had a single damp spot since."

"I had two rented terraced houses with bad exterior render — cracked, patchy and leaking in a couple of spots. The corkspray sorted the facade, improved the look completely, and the tenants have commented on the warmer walls."

"Old stone cottage on the west coast — we were losing heat through the gable wall badly. The breathable corkspray was important to us as we didn't want to trap moisture. Very happy with the result."
