GWR NANO INSULATION® versus an uninsulated reference house.
Annual energy saving
Thermal insulation, applied like paint
Liquid nanotechnology thermal insulation coating.
GWR NANO INSULATION® is a liquid, site-tintable thermal insulation coating. Its thermal performance is delivered by vacuum-filled glass-ceramic microspheres uniformly dispersed within a polymer binder.
Climate imperative
Embodied carbon is an increasingly decisive factor in the built environment's decarbonisation pathway.
37% Share of global energy-related CO₂ from buildings (IEA, 2023)
75% Share of EU buildings rated energy-inefficient (European Commission)
< 1% Annual energy renovation rate across the EU building stock
Buildings are responsible for approximately 37% of global energy-related CO₂ emissions - 28% operational, 11% embodied (IEA, 2023). Embodied carbon covers the total CO₂-equivalent released across the manufacture, transport, installation, maintenance and end-of-life disposal of building materials - a category that operational energy efficiency programmes do not address. As building energy standards tighten and operational carbon falls, the embodied share rises proportionally: for new buildings, half of future CO₂ emissions will come from embodied carbon, half from operations (Dodge World Green Building Trends Report, 2021).
The regulatory framework has formalised this relationship. The EU Taxonomy and the Magyar Nemzeti Bank (MNB) green financing programme treat Life Cycle Assessment (LCA) and Global Warming Potential (GWP) calculation as mandatory requirements; Environmental Product Declaration (EPD)-based embodied carbon data is increasingly a condition of project financing. Meanwhile, the built environment's most pressing embodied carbon challenge lies in the existing stock: two-thirds of the 2050 European building stock has already been built, and the annual energy renovation rate remains below 1% of the stock. The EU Renovation Wave programme aims to double that rate - but a technological and economic gap persists between policy ambition and deliverable retrofit solutions.
GWR NANO INSULATION® is designed for the retrofit constraints of the existing building stock. Its liquid application, 1 mm working thickness and no-scaffold delivery involve significantly less material input than conventional EPS-based insulation systems. The TÜV SÜD-verified 43% annual energy saving reduces the building's operational carbon - reproducible performance verified by accredited laboratory data.
Applied like paint. Certified thermal performance.
- 01
Cost-effective solution
No structural modification, mechanical anchoring system or additional structural load is required; the coating is applied directly onto the existing substrate without demolition or subsequent surface restoration.
- 02
No scaffolding required
The coating is applied by airless spray; scaffolding is typically not required on low and medium-height surfaces but can be used where needed on more difficult-to-access or taller areas.
- 03
Even a 3-person crew is sufficient
Airless spray application enables fast, efficient work particularly suited to commercial and industrial projects where minimising site downtime and work-area occupancy is a priority.
- 04
Fast application
The complete facade of an average-sized, single-storey family home can be coated within 3 working days; actual project duration depends on building size, geometry and the number of coats specified.
- 05
Minimal waste generated
Liquid application eliminates offcuts and construction debris; material loss is negligible, the work area is easy to keep clean, and only minimal tidying is required once application is complete.
- 06
20-year workmanship warranty
The contracting applicator provides a 20-year workmanship warranty under the individual works contract; its scope is engagement-specific and determined by the contracting parties within the framework of applicable law.

Product properties
A single coating, specified everywhere it has to perform.
GWR NANO INSULATION® bonds reliably across substrates, maintains stable thermomechanical properties through extreme temperatures, and remains breathable, washable and tintable for life.
Excellent adhesion
Bonds to metal, concrete, brick, wood, plastic, glass and plasterboard without a primer coat - broad substrate compatibility across complex building assemblies.
Flexible and durable
The coating flexibly follows substrate thermal and mechanical deformation without cracking - its impact resistance and layer integrity are maintained throughout the building structure's design life.
Thermal-bridge-free
Applied to window and door frame junctions, it reduces linear thermal bridge effect, equalises internal surface temperature and mitigates condensation risk.
Vapour-permeable
Maintains substrate vapour diffusion capacity across the entire treated surface - preventing surface condensation, moisture accumulation and microbial growth.
Weatherproof and washable
Resistant to UV radiation, precipitation and extreme thermal cycling - TÜV SÜD weather-simulation testing confirms durable performance across the full operating range.
Anti-corrosion protection
The coating seals metal surfaces from corrosive media - a two-year immersion field study confirmed complete corrosion protection while uncoated references corroded severely.
Antibacterial activity
Antibacterial activity on treated surfaces is verified by accredited laboratory testing - surface colonisation by pathogenic bacteria is substantially inhibited.
Fire-resistant
Accredited fire testing verifies limited flame spread and minimal smoke development - certified under both European and North American fire safety classification systems.
Tintable on site
Compatible with acrylic pigment systems - the target colour blends directly into the coating mix. No separate decorative layer required.
How GWR NANO INSULATION® works
Three heat transfer mechanisms countered in one layer.
GWR NANO INSULATION®'s nanotechnology-based structural design suppresses conductive, convective and radiative heat transfer simultaneously - through a combined microsphere system and a functional polymer binder.
- 01 Conduction barrier
Vacuum-filled glass-ceramic and gas-filled polymer microspheres jointly reduce the thermal conductivity of the solid phase.
- 02 Convection barrier
The closed shell structure of the microspheres and polymer binder prevents convective air movement within the coating.
- 03 Radiation barrier
The glass-ceramic and high-refractive-index titanium dioxide content reflects and scatters infrared radiation, reducing radiative heat flux.
