GWR NANO INSULATION® completed coating on trapezoidal steel decking and structural beams, Qatari stadium — uniform white texture, close view

Lusail National Stadium and Al-Thumama Stadium

Total treated area
113,800 m²
Lusail National Stadium (88,966 seats)
78,000 m²
Al-Thumama Stadium (40,000 seats)
35,800 m²

At two venues of the 2022 FIFA World Cup, with completed MEP installations already in place, the available installation clearance was too restricted for any conventional insulation system to be physically applied. GWR NANO INSULATION® at 1 mm dry film thickness met the prescribed thermal requirements; the installation was carried out by our exclusive regional partner, Q Green Trading and Contracting W.L.L. Treated substrates: reinforced concrete, AAC block, plasterboard partitions, floors, ceilings, trapezoidal steel, structural steel and stand soffit.

The external envelope surfaces of the two-storey modular accommodation complex were coated with GWR NANO INSULATION®. A lightweight envelope stores almost no heat and its surface temperature tracks solar radiation without lag, so radiant gain accounts for much of the summer cooling load. The coating lowers the solar absorptance of the outer surface, and with it the heat flux entering through the structure and the compressor running time. At 1 mm it leaves the geometry and the weight of the modules unchanged, so they stay demountable; the air-conditioning units, the steel stair and the windows stayed in place.

Private residence with a curved pediment and columned loggia, facade treated with GWR NANO INSULATION® coating, Gödöllő
Residential · Retrofit Gödöllő, Hungary

Grand private residence – facade and terrace insulation

Full facade and horizontal terrace insulation of a private residence articulated by a curved pediment and a columned loggia. The curved surfaces, columns and other architectural features cannot be clad in conventional insulation boards for geometric reasons; GWR NANO INSULATION® applied by airless spray conforms uniformly to every surface profile, forming an uninterrupted coating.

Family house with a pale yellow facade being coated with GWR NANO INSULATION®, openings masked with protective sheeting, Budapest District III
Residential · Retrofit Budapest, District III, Hungary

Family house – facade insulation during application

The coating was applied by airless spray directly onto the existing render, with openings, plinth and ground protected by masking film. The house stayed occupied throughout: no demolition, no anchoring system, no levelling coat. The reveals were coated as well, with a proper edge termination at the sills. At 1 mm dry film the opening dimensions are unchanged and no sill replacement is needed, so the facade keeps its original articulation.

Two-storey family house with a light facade coated with GWR NANO INSULATION®, timber balcony and partial scaffolding, Salgótarján
Residential · Retrofit Salgótarján, Hungary

Two-storey family house – facade insulation

Full facade insulation of a two-storey dwelling. Partial scaffolding served the upper sections while the lower surfaces were reachable from a ladder, so the work progressed without closing off the ground around the house. The coating follows the balcony soffit, the window reveals and the roof edges alike; the timber balcony railing and the entrance canopy stayed in place, since a thin-film coating does not force the junctions to be rebuilt.

Light commercial vehicle cargo area with a GWR NANO INSULATION® interior coating — coated roof panel, perforated roof bows and side panels, rear doors open
Commercial vehicle · Cargo area Budapest, District III, Hungary

Light commercial vehicle cargo area – interior thermal coating

Full interior coating of the load space of a light commercial vehicle. Thin sheet-steel bodywork has little thermal mass and high conductance, so the load space heats up fast in summer and cools just as fast in winter. The sprayed coating follows the roof ribbing, the perforated roof bows and the side panels as one continuous surface; unlike board insulation it costs no internal clearance.

Container house facade with a GWR NANO INSULATION® coating — horizontal board-profile cladding and the adjoining rendered surface in raking light, Pócsmegyer-Surány
Container house · Facade coating Pócsmegyer-Surány, Hungary

Container house – facade coating on rendered and clad surfaces

Facade coating of a container house on clad and rendered surfaces. On a light envelope with little thermal mass the summer load is largely solar, so the coating went onto the external face; the board-profile cladding and the rendered section each needed their own substrate preparation. The sprayed thin film follows the profile, does not build up at the overlaps, and adds no appreciable load to the light structure.

Interior surfaces of an attic with a GWR NANO INSULATION® coating — coated sloping roof plane, exposed framing and gable wall, Budapest District III
Family house · Attic coating Budapest, District III, Hungary

Attic – roof plane and exposed framing

The entire internal envelope of the attic was coated: the sloping roof plane, the gable walls and the exposed framing, sides and soffits included. The roof carries the highest summer heat load of the building and passes it straight into the space below, while continuity of insulation is hardest to achieve exactly along the edges and junctions. The sprayed application forms an unbroken layer across those too, and takes no headroom.

Two-colour GWR NANO INSULATION® coated facade of a family house with a converted roof space, oriel and garages, worked from a ladder, Paks
Family house · Facade coating Paks, Hungary

Family house – facade coating without scaffolding

Facade coating of a family house with a converted roof space. The coating was applied in two colours, over the rendered wall fields, the plinth band, the pilaster strips, the oriel and the wall faces at garage level. It was sprayed from a ladder, so no scaffold had to be raised in front of the building and the garages and the entrance stayed in use throughout. At 1 mm the film does not bury the mouldings: their projection is kept and the line between the two colour fields stays sharp.

Two-storey modern private dwelling facade with GWR NANO INSULATION® coating, Siófok — white render, pre-completion state
New-build residential Siófok, Hungary

Modern two-storey dwelling – facade insulation

GWR NANO INSULATION® can replace conventional External Thermal Insulation Composite Systems (ETICS): applied directly to the existing render substrate with no structural intervention, mechanical fixings or render build-up. There is no adhesive bed and no rail framework: the facade thickness and geometry are effectively unchanged, the original arrises and window reveals keep their definition, and the installation programme is significantly shortened.

Completed multi-storey panel block facade with GWR NANO INSULATION® coating — street view
Residential · Retrofit Jászberény, Hungary

Multi-storey panel block – facade thermal insulation

Airless spray application can be carried out from elevated work platforms without full scaffold erection. Resident disruption and site exclusion periods are minimised; no through-panel fixing penetrations require sealing or remediation after completion. The joint-free coating also reduces thermal bridging at panel junctions, the weak points board insulation tends to leave untreated. The treatment suits energy retrofit programmes targeting a sustained reduction in residents' utility costs.

Interior structural ribs of a metal-framed glass roof section treated with GWR NANO INSULATION® coating — MarázPlast, Kaposvár
Commercial · Industrial Kaposvár, Hungary

Glazed industrial roof – internal insulation

Thermal treatment of the internal structural ribs and adjoining aluminium profiles of the metal-framed glass roof at MarázPlast's site. The coating both reflects infrared radiation and adds thermal resistance, attenuating solar heat flux and reducing summer heat gain and air-conditioning demand in the space beneath the glazed roof. In winter the same resistance reduces heat loss through the metal frame, without affecting light transmission.

Listed heritage building with arched window surrounds and ornamented cornice, treated with GWR NANO INSULATION® coating, Gödöllő
Listed building · Retrofit Gödöllő, Hungary

Listed heritage building – facade insulation

On a building under monument protection, heritage regulations strictly limit the scope of intervention: its visible appearance and ornamental elements cannot be altered. Conventional board insulation, several centimetres thick, would obscure the arched window surrounds and cornice profiles. At 1 mm dry film, GWR NANO INSULATION® improves thermal performance while leaving the original appearance unchanged and the work within the heritage requirements.

Multi-storey panel block facade partially coated with GWR NANO INSULATION®, self-propelled lift platform — treated and untreated surface side by side
Residential · Retrofit Budapest, District IV, Hungary

Multi-storey panel block insulation

One section of the facade already shows the GWR NANO INSULATION® coating's smooth, uniform finish, while the adjoining section remains untreated, with the original panel texture still exposed. Application from a self-propelled lift allows the works to proceed on a defined schedule, section by section, without disrupting residents. The contrast sets the seamless, joint-free finish against the untreated panel surface, and it closes as the retrofit progresses.

Thermographic inspection – measurement documentation

The cooler, lighter-toned square in the thermal image is the section of metal cladding treated with GWR NANO INSULATION® — under thermal loading it heats up far less than the surrounding untreated trapezoidal steel, which reaches a visibly high surface temperature (yellow-red range). Captured in a single frame under the same ambient load, the image shows the temperature difference between the treated and untreated surface.

Two-storey family house facade with GWR NANO INSULATION® coating in two distinct colour tones, Paks
Family house · Facade insulation Paks, Hungary

Two-storey family house – facade insulation

On this two-storey family house, the GWR NANO INSULATION® coating was applied in two distinct colour tones — the coating can be tinted on site, so the upper and ground-floor sections read as separate without any additional decorative layer. The coating forms a continuous, seamless surface across the entire facade, including the varying wall geometry and the eaves junctions at roof level, keeping the boundary between the two tones sharp and stable.

Two-storey medical clinic facade with GWR NANO INSULATION® coating, Budapest District XVII
Healthcare facility · Renovation Budapest, District XVII, Hungary

Medical clinic – facade insulation

At an actively operating medical clinic, the works were carried out in scheduled phases without disrupting patient care: airless spray dries quickly, so work areas had to be closed off only briefly. In a healthcare setting the accredited laboratory-verified antibacterial surface effect of the coating carries particular weight, since it meaningfully inhibits the growth of pathogenic bacteria on the treated surfaces, which serves patients and staff alike.

Two-storey family house with a white GWR NANO INSULATION® coated facade and closed, likewise coated roller shutter curtains, work in progress, Budapest District II
Family house · Facade and shutters Budapest, District II, Hungary

Family house – facade and roller shutter coating

Facade coating of a two-storey family house, including the roller shutter curtains. A closed shutter is one of the hottest elements of a facade: the thin, low-mass slats take the direct solar load and radiate the heat they absorb back towards the glazing. A thicker coating is not an option here, since it grows the diameter of the rolled curtain and binds the slats in the guide rails. At 1 mm dry film the rolled diameter is unaffected, and the shutters stayed operable with no readjustment.

Gable elevation of a family house with a GWR NANO INSULATION® coating, the eagle sculpture at the apex and arched windows in rusticated stone surrounds, Dunabogdány
Family house · Facade and ornament Dunabogdány, Hungary

Family house – facade and gable eagle sculpture

Coating of a gable elevation together with the eagle sculpture standing on its apex. Free-standing on every side, the sculpture takes driving rain, UV load and winter freeze-thaw cycles; decay is driven mainly by moisture freezing in the pores. The coating preserves the vapour diffusion of the substrate, so moisture is not sealed in, and at 1 mm it does not blunt the worked detail of the surface. The rusticated stone window surrounds were left uncoated.
