Gutex Thermoroom – Natural Wood Fibre Internal Insulation for Period Homes in Dublin
Gutex Thermoroom is a fully breathable natural wood fibre internal insulation board designed specifically for solid masonry walls and single-leaf construction. Manufactured from recycled waste wood chips, it delivers high thermal performance, moisture safety, and superior comfort all year round.
It is one of the most suitable solutions for period home renovations, especially properties constructed before 1940, where vapour-open materials are essential for managing moisture and preventing long-term damage.
Why Choose Gutex Thermoroom for Dublin Homes?
✔ Ideal for Traditional & Historic Properties
Gutex Thermoroom is perfectly suited to:
- Georgian homes
- Victorian houses
- Edwardian terraces
- Cottages and farmhouses
- Any pre-1940 solid-wall construction
These buildings typically use lime mortar, breathable plasters, and single-leaf masonry that behaves very differently from modern blockwork. Thermoroom supports these original materials rather than trapping moisture inside the structure.
Key Benefits of Gutex Thermoroom
- Fully Breathable Moisture-Safe Insulation
The board is naturally vapour-open, allowing moisture to diffuse safely through the wall structure. This helps:
- Prevent condensation
- Reduce mould growth
- Maintain healthy indoor humidity
- Protect historic masonry from trapped moisture
- Excellent Thermal Performance
Gutex Thermoroom improves energy efficiency by reducing heat loss through cold solid walls — essential for older Dublin properties that often lack cavity insulation.
- Superior Summer Overheating Protection
Unlike synthetic insulation, natural wood fibre has high thermal mass, providing exceptional summer heat protection, keeping rooms cool even during warm periods.
- Outstanding Acoustic Performance
The dense wood-fibre structure significantly improves sound insulation, reducing external noise — beneficial for terraced houses and busy Dublin streets.
- Eco-Friendly & Sustainable
- Made from recycled waste wood fibres
- Low embodied carbon
- Non-toxic, healthy building material
- Ideal for eco-renovation and deep retrofits
Internal Insulation for Single-Leaf Masonry Walls
Many Dublin and Irish period houses have single-leaf solid masonry walls that cannot accept traditional cavity insulation. Gutex Thermoroom is specifically designed to work with:
- Solid brick walls
- Solid stone walls
- Rubble or mixed masonry
- Lime-rendered internal surfaces
Its compatibility with breathable plasters and natural materials makes it the safest internal insulation choice for traditional buildings.
Why Breathability Matters in Older Homes
Homes built before 1940 were constructed with materials that actively absorb and release moisture. Using non-breathable insulation (foam boards, foil-backed systems, vapour barriers) can trap moisture, causing:
- Damp patches
- Rot in timber elements
- Degradation of brick or stone
- Poor indoor air quality
Gutex Thermoroom ensures the building continues to function as originally designed — safely, naturally, and efficiently.
