Professional HVAC & Ventilation
Complete HVAC insulation and ventilation system installation for commercial buildings, industrial facilities, and marine vessels. Energy-efficient, code-compliant, delivered on schedule across Denmark.
Thermal & Acoustic Insulation for Air Systems
HVAC (Heating, Ventilation, and Air Conditioning) insulation involves the application of thermal, acoustic, and moisture-control materials to ductwork, ventilation shafts, AHUs (Air Handling Units), and associated piping. Properly insulated HVAC systems reduce energy loss by up to 30%, prevent condensation on cold-air ducts, eliminate noise transmission, and ensure indoor air quality standards are met.
In Denmark, HVAC insulation must comply with DS/EN standards and the Danish Building Regulations. Izotehas insulates HVAC ductwork in hospitals, office buildings, data centres, pharmaceutical facilities. All certified, all documented.
How We Insulate Your HVAC Systems
A proven four-step approach that ensures precision, compliance, and minimal disruption to your building occupants and project schedule.
System Assessment
We review the HVAC design drawings, duct layouts and equipment schedules to identify insulation requirements - thermal, acoustic or both before any materials are specified.
Material Specification
We select insulation matched to the application: mineral wool for fire-rated ductwork, Armaflex for cold pipes and AHU connections, acoustic wrap for noise-sensitive areas. All materials meet DS 452 and BR18 requirements.
Installation
Our crew installs duct insulation, pipe insulation and equipment lagging on site, coordinating with mechanical and electrical trades to keep your programme on track.
Documentation & Handover
Full compliance documentation at handover - insulation class, materials used, coverage records. Ready for building control and quality audits without follow-up.
Where HVAC & Ventilation Insulation Matters
From commercial offices to hospitals - wherever air handling, ventilation or cooling systems run, insulation determines energy performance and indoor comfort.
Commercial Office Buildings
Duct and pipe insulation for office developments - thermal performance, condensation control and acoustic separation between floors and zones.
Hospitals & Healthcare
HVAC insulation for hospitals and healthcare facilities where hygiene, fire rating and acoustic performance are non-negotiable requirements.
Residential Developments
Ventilation duct insulation for apartment buildings and housing developments to DS 452 and BR18.
Industrial Facilities
Insulation for industrial ventilation and process air handling systems - thermal control, condensation prevention and noise attenuation.
Cold Storage & Refrigeration
Cold insulation for refrigerated warehouses, cold rooms and freezer facilities - condensation control and vapour barrier installation.
Cleanrooms & Pharma
HVAC insulation for pharmaceutical production and cleanroom environments with material traceability and GMP-compatible installation.
Certified HVAC Insulation Across Denmark
Izotehas delivers HVAC and ventilation insulation with certified processes, verified materials, and project management that keeps your construction schedule on track.
DS 452 & BR18 Compliant
Every installation meets Danish insulation standards and building regulation requirements, with full documentation.
Condensation-Free Design
Our vapour barrier installation methodology eliminates condensation risk on cold ductwork - preventing mould, corrosion, and indoor air quality problems.
Own Certified Workforce
We never subcontract core HVAC insulation work. Every technician on your site is trained, certified, and employed by Izotehas.
HVAC & Ventilation FAQ
What types of HVAC systems does Izotehas insulate?
Izotehas insulates all types of HVAC systems: supply and return air ductwork, exhaust ventilation, kitchen and fume extraction, AHU housings, chilled water piping connections, and hot water heating coils. We work with rectangular, circular, and flat-oval ductwork in all common materials.
Why is duct insulation important for energy efficiency?
Uninsulated ductwork can lose up to 30% of heating or cooling energy before air reaches its destination. Properly installed duct insulation maintains supply air temperature, reduces HVAC system load, and delivers measurable energy cost savings. In Denmark, duct insulation thickness is prescribed by the Building Regulations based on duct location and system type.
What insulation materials are used for HVAC ducts?
We select materials based on application: mineral wool (stone wool or glass wool) with aluminium foil facing for general thermal and acoustic duct insulation, Armaflex (elastomeric foam) for condensation control on cold-air ducts, phenolic foam board for high-performance thermal efficiency, and acoustic foam liners where noise attenuation is the primary requirement. Each material is matched to DS/EN requirements.
Can you insulate HVAC systems in occupied buildings?
Yes. Izotehas insulates HVAC ductwork in office buildings, production facilities. We coordinate with facility management to schedule work during low-occupancy periods, maintain strict dust and cleanliness protocols, and ensure ventilation system downtime is minimised.
How quickly can you start an HVAC insulation project?
We typically begin site assessments within 5 business days of receiving an enquiry. Full mobilization timelines depend on project scope, but our 24-hour response guarantee means you always know the next step. Contact us for a specific timeline.
