Energy
Room energy performance
Surface radiation behaviour can contribute to a more even feeling at wall surfaces.
Important to know
To be checked per building. No guaranteed savings, and no equivalence to insulation.
ISORYX for hotels · distributed by Isonova
Rooms that feel right, renovated in phases.
Thoughtful coating options for guest rooms, facades, wellness and technical areas. Explore where each ISORYX product fits and what must be checked first.

Energy & building
Energy performance must be assessed per building. No savings are guaranteed.
Acoustics & sound insulation
Room acoustics is not sound insulation. No quieter neighbouring rooms are promised.
Indoor air & emissions
VOC Label A classifies emissions. It is not proof of air cleaning.
Moisture & mould
Mould prevention depends on moisture, ventilation and proper remediation.
Surface hygiene
ISO 22196 is a surface laboratory test, not room-air sterilisation.
Fire safety & build-up
Fire class A2-s1,d0 applies only to tested build-ups and the matching product documents.
Application explorer
Where in your hotel?
Choose an area to see the suitable product, the working steps and what needs checking.
Guest rooms and corridors
Interior walls and ceilings of bedrooms can be coated while the building stays in operation floor by floor. Surfaces feel calmer to the eye and the coating is part of a wider comfort concept.
Suitable productISORYX Inside, with Primario where the substrate requires it
How it is usedInspect, clean and dry the substrate, prime if needed, then apply by roller, brush or spray according to the technical data sheet.
Check firstRoom acoustics may benefit as a supplementary effect, but this needs a project-specific acoustic assessment. It is not airborne or impact sound insulation.
Wellness and bathrooms
ISORYX is never a waterproofing replacement. Direct water contact areas need proper sealing systems. Mould requires remediation of the cause.
How it works
Summer and winter, in one picture
A qualitative view of radiant heat at a wall surface. It illustrates the principle and shows no measured values.
In summer, solar heat reaches the facade. The coating reflects part of the radiant heat at the surface, which can help the room feel less heated by its own walls.
Schematic only. Actual effect depends on the building. It is not a replacement for conventional insulation and no savings are promised.
Comfort and operations
What it means for guests and for you
Each benefit is shown with its qualification.
Sound
Acoustics
Possibly a supplementary benefit for room acoustics, meaning how a room sounds inside.
Important to know
Needs project-specific acoustic assessment. Not airborne or impact sound insulation, so no promise of quieter neighbouring rooms.
Air
Indoor air
ISORYX carries VOC Label A for low emissions, supporting a considerate material choice.
Important to know
An emissions classification, not proof of active air cleaning. No allergy claims.
Surface
Mould and hygiene
Dry surfaces are less welcoming to mould. ISO 22196 laboratory testing relates to surfaces.
Important to know
Prevention depends on moisture and ventilation, and existing mould needs remediation. Not room-air sterilisation.
Safety
Fire behaviour
A2-s1,d0 is documented for tested build-ups.
Important to know
Valid only within tested build-ups and the product documents. Not to be read as the highest class.
Phasing
Operations
Inside is solvent-free and odour-neutral, and can be planned room by room, which suits a hotel that wants to stay open.
Important to know
Timings come from the technical data sheet and project planning, not from this page.
The four products
Which one, where
ISORYX Inside
Suitable interior walls and ceilingsFor rooms, corridors and common areas.
ISORYX Outside
FacadesFor exterior surfaces exposed to weather.
ISORYX Dry Cool
Cold rooms, cold technical surfacesFor surfaces in cold and technical zones.
ISORYX Primario
Preparation of the substrateMatched to the substrate before topcoat.
Application
From substrate to finished wall
Method and values always follow the technical data sheet.
Inspect
Assess the substrate and any moisture cause.
Clean
Remove dirt, loose material and residues.
Dry
Let the substrate become suitably dry.
Prime if needed
Primario, matched to the substrate.
Apply
Roller, brush or spray as the data sheet specifies.
Application at a glance
For ISORYX Inside and Outside, per their technical sheets: substrate clean, dry and firm; defects and causes of mould fixed first; absorbent substrates get Primario, other substrates need specialist primer advice; by roller or brush normally two coats to a minimum dry-film thickness of 0.40 mm; drying about 24 h per coat at 20 °C and 65 % RH, longer when cooler or more humid. Dry Cool has its own documents and is not covered by these values.
Technical data sheets (Original in German)
Phased renovation
Renovate without closing the house
A sensible sequence reduces disruption. Sequence and duration are set per project.
Assess
Walk the building, review substrates, moisture and ventilation.
Pilot
Choose a few rooms or one corridor to start.
Floor by floor
Release rooms in groups and keep the rest in operation.
Common areas
Schedule lobby and restaurant at quiet times.
Facade and technical
Plan weather-dependent and technical areas separately.

FAQ
Questions hotel teams ask
Will it lower our energy bill?
Energy performance has to be checked per building. We do not guarantee savings or percentages.
Will neighbouring rooms be quieter?
No such promise is made. Room acoustics describes the sound inside a room. Airborne and impact sound insulation are different matters. Any acoustic benefit needs project-specific assessment.
Can it be used in the spa?
Only after each wet-zone surface has been assessed. It never replaces waterproofing.
Does it clean the air or cure mould?
No. VOC Label A classifies emissions. Mould prevention depends on moisture and ventilation, and existing mould requires remediation.
Is it fire rated?
A2-s1,d0 applies only within tested build-ups and the relevant product documents.
