Creating a healthy, warm and truly cozy interior starts with doing insulation properly. The superior Unfollow Insulation System is designed to manage temperature, moisture and acoustics at the source, transforming a bare metal van into a comfortable, all-season living space.
We begin by coating the entire interior shell of the van with three continuous layers of Spray Cork. This forms the foundation of our insulation system and addresses one of the biggest problems in camper conversions: condensation.
Did you know that Unfollow is the only provider of superior, all natural campervan insulation systems in Ireland?
Spray Cork – the breathable base layer
Spray Cork is a completely natural material made primarily from cork granules. It is applied directly to every exposed metal surface, ensuring no thermal bridges are left behind.
Key properties:
- Thermal performance:
Spray Cork provides an excellent R-value, reducing heat loss while stabilising interior temperatures. - Vapour barrier & condensation control:
By fully encapsulating all metal parts, Spray Cork prevents warm interior air from meeting cold steel, dramatically reducing condensation and corrosion risk. - Natural & non-toxic:
Free from harmful chemicals, safe for indoor air quality, and ideal for long-term living. - Acoustic insulation:
Excellent sound-dampening properties help reduce road and rain noise. - Fire safety:
Cork is naturally fire-resistant and self-extinguishing, contributing to a safer living environment. - Design flexibility:
Available in a wide range of colours, allowing the insulation layer itself to become part of the interior aesthetic if desired.
Sheep’s Wool – cavity insulation done right
Once the Spray Cork base layer is complete, all wall, ceiling and cavities are filled with premium sheep’s wool insulation.
Sheep’s wool is one of the most advanced natural insulation materials available and is uniquely suited to camper living.
Key properties:
- High thermal efficiency:
Sheep’s wool delivers a very good R-value, providing excellent insulation against both cold and heat. - Moisture regulation:
Sheep’s wool can absorb up to 30% of its own weight in moisture without feeling wet, then slowly release it. This actively regulates humidity and works in harmony with the Spray Cork layer. - Naturally fire-retardant:
Wool is difficult to ignite and does not melt or drip, adding another layer of safety. - Air-purifying properties:
It naturally absorbs and neutralises airborne pollutants, improving interior air quality. - Sustainable & renewable:
A low-impact, biodegradable material with excellent longevity.
The result
By combining Spray Cork as a continuous insulating and vapour-control layer with sheep’s wool for high-performance cavity insulation, the Unfollow Insulation System delivers:
- Stable interior temperatures in all seasons
- A dry, condensation-free living space
- Quiet, comfortable acoustics
- Natural, breathable and fire-safe materials
- A healthier environment for everyday van life
This layered approach is not just insulation — it’s the foundation of a camper designed for long-term comfort, durability and wellbeing.
