NOVERA Exterior

NOVERA Exterior

A protective thermo-reflective coating that protects structures, cools buildings, and gives façades a new life.

Flexible like rubber.
Durable like stone.
Intelligent like light.

 

NOVERA Exterior is like armor that breathes.
A thin, elegant layer you barely notice on the façade, yet its physical effect can change the entire energy balance of a building.

It is a membrane that:

– reflects radiant heat,
– stabilizes surface temperature,
– protects structures from water and UV radiation,
– allows masonry to breathe,
– increases the thermal stability of the building,
– extends its lifespan.

Microspheres inside the coating act like thousands of tiny mirrors — a 360° reflection without blind angles. The façade does not absorb excess heat, overheats less, and the structure beneath remains cool, stable, and protected long-term against extreme weather.

It is a smart, thermo-active, flexible, and microstructurally balanced protective coating. The result is a façade that becomes an active climate system — natural, clean, and effective without massive construction interventions.

BENEFITS

Significantly reduces structural overheating

thanks to microspherical IR reflection and high surface emissivity.

Thermo-reflective & thermo-active technology

actively works with heat flow, not just color-based.

Vapor-permeable yet hydrophobic

the wall can breathe but does not absorb moisture.

UV-stable – color permanence even after 8+ years

verified by UV testing, 1000 hours without degradation.

Improves the building’s energy stability

lower cooling and heating costs.

Highly flexible (200–300%)

protects against microcracks and thermal expansion.

Very high adhesion

in most cases without the need for penetration.

Eco-friendly, VOC-free

suitable for sustainable, ESG, and green buildings.

Service life 25+ years

in accordance with the NOVERA system, ETAG 005 – W3 equivalent for roofing systems.

Resistant to erosion, salt mist, smog, rain, frost, and thermal shock.

TECHNOLOGY

WHAT IS NOVERA EXTERIOR

NOVERA Exterior is an intelligent, highly functional thermo-reflective coating
with a comprehensive physical–material design:

1) Microspheres – the key to IR spectrum reflection

hollow ceramic and glass microspheres
360° reflection without blind spots
operates in the IR spectrum → real heat management

2) Thermo-active polymer matrix

extremely flexible
UV stable
resistant to precipitation and cold (down to −35 °C)
does not promote crack formation

3) Mineral microfillers

provide mechanical strength
enable vapor permeability
stabilize the structure against settlement

4) Hydrophobic architecture

water is not absorbed
droplets run off the surface
minimizes the risk of freeze–thaw cycles

5) UV stabilizers and protective filters

minimize yellowing
protect against degradation and embrittlement
guarantee long-term color stability

Result

The façade absorbs tens of percent less solar energy and remains cooler, cleaner,
and more durable, while the structure beneath is stabilized and protected over the long term.

APPLICATION

NOVERA Exterior is suitable for:

Materials

concrete (smooth and rough)
aerated concrete / Ytong
ceramic and silicate masonry
mineral plasters
cement-bonded particle boards
OSB and wood-fiber boards
drywall, gypsum fiber boards
metal structures
composite materials

Types of buildings

family houses
apartment buildings
administrative centers
commercial buildings
halls and warehouses
healthcare facilities
schools and kindergartens
public buildings
renovations and new constructions

NOVERA Exterior is also suitable for urban projects, where it supports municipal Urban Cooling strategies.

KEY FUNCTIONS AND PROPERTIES

1. Thermo-reflective technology – operation in the IR spectrum

reflects up to 80–88% of the IR component
façade surface temperature is reduced by 8–15 °C
interior spaces remain more stable during tropical days
minimizes thermal stress on structural layers

2. Thermo-active behavior – intelligent heat management

less heat enters the building in summer
reduced heat loss in winter
ideal complement to thermal insulation systems
improves real energy performance parameters (PENB) during the summer period

3. Elasticity

bridges microcracks
resistant to vibration
high elasticity even in frost
seamless curing without peeling

4. Vapor permeability + hydrophobicity

vapor diffusion is preserved
walls remain dry
prevents condensation within the structure
protects against freeze degradation

5. UV and climatic resistance

stable even after 1000 hours of UV testing
does not yellow, crack, or delaminate
high resistance to erosion and smog

6. Ecology and sustainability

0% VOC
water-based
free of toxic substances
suitable for LEED / BREEAM / DGNB systems
The coating contributes to lower urban temperatures (part of the Urban Cooling effect).
