Why act
In a large hangar,
heat quickly becomes unmanageable.
Aerospace hangars combine huge non-air-conditioned roofs with large volumes. In summer, heat accumulates and penalises both teams and operations.
Air conditioning is out of reach
Air-conditioning such volumes costs a fortune in equipment and operation.
Extensive waterproofing to protect
Thousands of m² of waterproofing exposed to UV: a replacement is a huge budget.
Budgets framed in advance
Investments are planned in N+1/N+2: a predictable-cost solution is needed.
The common cause: a huge roof that absorbs heat instead of reflecting it.
The Covalba solution
A passive alternative
to industrial air conditioning.
Rather than air-conditioning volumes that are impossible to cool, cool roof treats the roof to reduce the heat transmitted — at a fraction of the cost of air-conditioning equipment.
Conventional roof
up to 80°Cat the surface
- Dark surface
- Absorbs heat
- Strains air conditioning
Cool roof
up to 90%of radiation reflected
- Light-colored surface
- Stays cooler
- Reduces the thermal load
- Passive solution, no energy consumption
- Applied from the outside, no downtime
- Suited to very large surfaces
- Predictable cost per m², plannable in N+1/N+2
On a hangar, cool roof delivers a far faster ROI than air-conditioning equipment, capex and opex included.
Durability
The Covalba system
holds up on very large surfaces.
On thousands of m², durability is decisive: starting over too soon is costly. Price per m² isn't enough; you have to count service life and retained reflectivity.

Aerospace dossier
Cool roof for the aerospace industry: cooling large hangars without air conditioning.
Aerospace hangars are among the largest industrial roofs. Non-air-conditioned and highly exposed, they become hard to bear in summer.
Why large hangars overheat in summer
An immense roof, often steel deck or dark membrane, absorbs most of the radiation and exceeds 80°C at the surface, transmitting its heat to a space impossible to air-condition.
A passive alternative to industrial air conditioning
Air-conditioning a large hangar means prohibitive investment and operating costs. Cool roof prevents heat from entering rather than fighting it once inside, at a fraction of the cost.
The cool roof principle, validated by research
A reflective roof combines high solar reflectance and high emissivity. Its effect is all the more marked as the roof surface is large.
Durable systems for very large surfaces
Covalba applies polyurethane systems with an anti-UV topcoat designed to last 8 to 20 years. For steel-deck hangars, CovaMetal adds anti-corrosion protection.
Predictable budget and multi-year planning
With a controlled cost per m², cool roof is easy to plan for an N+1 or N+2 financial year. Covalba provides a clear quote, free of commitment, that fits your programme.
A safe operation, with no downtime
Everything happens from the outside, machines on the ground: no load or vibration on the hangar structure, and ground activity continues as normal.
