Under Bonnet Insulation
Under Bonnet Heat Shield for Vans – Protect, Insulate, and Quiet Your Ride
A well-insulated engine bay not only controls heat but also helps reduce noise and improve overall vehicle comfort. Kool Wrap’s high-performance under bonnet heat shield for vans is designed to reflect radiant heat, reduce engine noise, and prevent heat soak into the cabin or electrical systems.
Why Install a Van Under Bonnet Insulation Shield?
Most factory bonnets lack proper insulation, especially in commercial and older van models. Excessive engine heat can penetrate the bonnet and firewall, leading to a hotter cabin, degraded paintwork, and reduced component lifespan. Our van under bonnet insulation products are the perfect upgrade to improve thermal and acoustic performance.
Key Benefits:
- Reflects radiant engine heat away from the bonnet
- Reduces heat transfer into the cabin
- Dampens engine vibration and road noise
- Protects paintwork from heat damage
- Enhances thermal performance of under-bonnet systems
Whether you’re maintaining fleet vehicles or customising a campervan, Kool Wrap’s solutions offer superior under-bonnet protection.
Heat Shield Under Bonnet for Vans – Durable and High-Performing
Kool Wrap’s heat shield under bonnet for vans is made from advanced materials such as aluminium foil-faced fiberglass, ceramic wool, and acoustic foams — all bonded to create a multi-layered heat and sound barrier.
Product Features:
- Rated to withstand 500°C+ continuous heat
- Self-adhesive or mechanical fix installation
- Lightweight yet highly effective
- Available in cut-to-fit or pre-sized panels
The result is better engine bay heat control, quieter cabin noise, and improved overall vehicle efficiency.
Bonnet Soundproofing for Vans – Silence the Rattle and Roar
Engine noise in vans can be loud, especially during start-up, idle, or heavy acceleration. Kool Wrap’s bonnet soundproofing for vans products include specially engineered sound-absorbing foams that reduce engine noise entering the cabin and improve the driving experience.
Where It Helps:
- In diesel vans with louder engines
- For campervans requiring quiet sleep environments
- In trade vehicles that spend long hours on the road
- For anyone wanting a quieter, more refined ride
This is especially useful for campervan builders looking to dampen noise near the sleeping area or during long-distance travel.
Reflective Insulation Under Bonnet for Heat Management
Reflective insulation is the most effective way to bounce heat back toward the engine and away from the bonnet’s surface. Kool Wrap’s reflective insulation under bonnet products use aluminium foil or silver-faced materials to deliver maximum heat deflection.
Application Zones:
- Directly under the bonnet skin
- On firewall surfaces facing the engine
- Along strut towers and inner guards
- On top of battery covers and fuse boxes
This layer protects paint, wiring, and plastic components from long-term heat damage — especially important in Australia’s hot climate.
Engine Noise Insulation for Vans – Quiet, Comfortable Driving
Our engine noise insulation for vans reduces vibrations, drone, and mechanical rattles. When combined with under-bonnet heat shields, the result is a noticeably quieter and more comfortable cabin environment.
Additional Benefits:
- Reduces engine “clatter” in diesel vans
- Works in tandem with floor and firewall insulation
- Improves acoustic quality for calls, music, or videos
- Makes cabins more peaceful for overnight stays
Van owners across Australia choose Kool Wrap not just for performance, but also for peace of mind — and peace and quiet.
