Energy Efficiency

GWR NANO INSULATION®

View product page

What annual energy savings does GWR NANO INSULATION® achieve?

TÜV SÜD EN ISO/IEC 17025 accredited laboratory testing confirms 43% annual energy saving versus an uninsulated reference building, 32% summer cooling saving and 9.5% winter saving versus a 10 cm EPS-insulated reference building.

How thick is the GWR NANO INSULATION® coating layer?

The dried coating is 1 mm thick. No primer coat, no structural modification, and no scaffolding are required for application.

What warranty does GWR NANO INSULATION® carry?

The contracting applicator - the party performing the specific application works - provides a 20-year applicator workmanship warranty. This warranty is contractual, engagement-specific, and governed by the applicable national construction law of the project jurisdiction. It is provided by the applicator, not necessarily by Summa Technologiae Kft.

What certifications does GWR NANO INSULATION® hold?

TÜV SÜD test certificate (EN ISO/IEC 17025 accreditation), Romanian CEA Technical Approval 001SC-03/403-2023 (CTPC/INCERC Cluj-Napoca), NATO Stock Number 8030-51-000-9542, ISO 9001:2015 quality management, ISO 14001:2015 environmental management, EU fire classification D-s2 d0 (MSZ EN 13501-1), and ASTM E84 Class A (FSI 20, SDI 10).

What temperature range does GWR NANO INSULATION® cover?

The coating operates across a service temperature range of −60 °C to +260 °C.

Can GWR NANO INSULATION® be applied without scaffolding?

Yes. Airless spray technology enables application without scaffolding or specialist access equipment. A standard family home can be fully coated inside and out within 3 working days by a 3-person crew.

Is GWR NANO INSULATION® vapour-permeable?

Yes. The coating maintains substrate vapour diffusion capacity (Sd equivalent air layer thickness 0.40 m, V2 medium class per DIN EN ISO 7783), preventing condensation and moisture accumulation.

Where has GWR NANO INSULATION® been applied at scale?

Among documented large-scale applications, 113,800 m² were applied across Lusail Stadium and Al Thumama Stadium for the FIFA World Cup Qatar 2022. A Vietnam field test recorded 43.02% average cooling energy savings and a peak single-day saving of 53.56%.

Can GWR NANO INSULATION® be used on listed or heritage-protected buildings?

Yes. Because the coating is only 1 mm dry film thickness, it does not alter the building's visible appearance, ornamental elements or profiled surfaces — making it suitable where heritage regulations prohibit visual changes to the façade.

How many countries is GWR NANO INSULATION® available in?

The product is currently available in 45 countries — across the European Union, the Middle East, and Vietnam.

Building Technology

How does DriftAir® reduce fuel consumption?

DriftAir® uses passive aerodynamic principles to increase natural chimney draught and reduce the heat energy lost with flue gases. Official measurements verify 20–40% average fuel savings per heating season for stoves, fireplaces and multi-fuel boilers, and 15–20% for gas heating systems.

Does DriftAir® require electricity or maintenance?

No. DriftAir® is a fully passive device with no moving parts, no external power source, and no maintenance requirement. Power consumption is 0 W. It is backed by a 10-year warranty.

What emission reductions does DriftAir® deliver?

By improving combustion efficiency, DriftAir® reduces particulate and pollutant emissions. PM2.5 fine particulate emission is reduced toward the 5 µg/m³ WHO annual air quality guideline target; the share of unburned combustible content in flue gas is reduced by approximately 63%.

Is DriftAir® compatible with all chimney types?

DriftAir® is a passive aerodynamic chimney cap compatible with a wide range of chimney configurations; the exact saving depends on chimney geometry and fuel type, verified through official measurements.

Wind Energy

Wind Driver VAWT

View product page

What is the minimum wind speed for the Wind Driver VAWT to generate power?

The cut-in speed is 1.2 m/s (4.3 km/h), compared with the 3–5 m/s threshold of conventional horizontal-axis wind turbines. This enables generation in low-wind urban and rooftop environments.

How loud is the Wind Driver VAWT in operation?

The measured sound pressure level is below 10 dB - well under every European urban noise standard reference threshold. Suitable for rooftop, industrial, public-space and residential installations.

What output range and model variants are available?

Four models are available: WD-M1 (1 kW rated, 1.1 kW max), WD-M3 (3 kW rated, 3.5 kW max), WD-M5 (5 kW rated, 6 kW max) and WD-M10 (10 kW rated, 12 kW max). Generator efficiency is 96%. Design lifecycle is 20 years.

Can the Wind Driver VAWT be combined with solar PV panels?

Yes. The Wind Driver VAWT is designed for integration with photovoltaic hybrid systems, supporting both on-grid and off-grid configurations.

What certifications does the Wind Driver VAWT hold?

CE marking, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018 (occupational health and safety), ISO 50001:2018 (energy management), and ISO 10002:2018 (customer satisfaction).

Security Technology

Security Technology

View product page

What security services does Summotive® provide?

Nine integrated service areas - physical guarding and site protection, reception and front desk services, personal close protection, event security, retail and commercial security, cash and valuables transport, security technology (CCTV, access control, fire alarm design and maintenance), 24/7 remote monitoring with dispatch, and security risk assessment.

Does Summotive® hold any formal security qualification?

Yes. The team holds NATO supplier qualification - verified compliance with personnel security, procedural and documentation requirements for critical infrastructure and classified information environments.

How does the security engagement process start?

Every engagement begins with an on-site security survey, threat and vulnerability analysis, and regulatory compliance review covering CSRD and TCFD frameworks. No service is deployed without this foundation.

Is 24/7 monitoring available?

Yes. A 24-hour dispatch centre receives and evaluates alarms from installed electronic systems in real time. An intervention team is dispatched where required, handled through a documented escalation protocol to closure.
