🛠️ How to Insulate a Campervan — Step-by-Step Guide
Transforming your van into a comfortable camper starts with one key step: insulation.
A properly insulated van keeps you warmer in winter, cooler in summer, and quieter on the road.
At Obsidian Leisure, we’ve tested a range of insulation products for camper conversions.
There are many options available, but we’ve consistently found Dodo Mat to be the best for soundproofing, temperature control, and lasting quality.
🔹 Step 1: Sound Deadening — Reduce Vibration & Noise
Before adding insulation, quieten your van’s metal panels to stop vibration and road noise.
🧰 Recommended Product: Dodo Mat Sound Deadening
Apply directly to:
Floor panels
Side walls
Roof sections
How to apply:
Clean all surfaces of dust, grease, and dirt.
Cut sheets to fit each panel.
Peel and stick, then press firmly with a roller to remove air pockets.
👉 You can find the full Dodo Mat Sound Deadening range on our store — high-performance sheets that drastically reduce noise.
🔹 Step 2: Thermal & Acoustic Insulation
Once the noise is handled, add insulation to help with heat retention and sound absorption.
🧰 Recommended Product: Dodo Mat Thermo Acoustic
This combines heat insulation and sound control in one easy-to-fit layer.
How to apply:
Cut to size for doors, side panels, and ceiling.
Stick over your sound-deadening layer.
Press down firmly for a tight bond.
Thermo Acoustic insulation reflects summer heat and keeps warmth inside during cold months.
🔹 Step 3: Add Loft-Style Insulation for Extra Warmth
To fill gaps and cavities, use a flexible fleece material.
🧰 Recommended Product: Dodo Mat Thermo Fleece
Made from recycled materials, it’s lightweight, safe to handle, and easy to shape.
How to apply:
Tear or cut to fit around braces and gaps.
Push into recesses — snug, not tight.
Cover with a vapour barrier or aluminium tape if preferred.
👉 We’ve tried several brands, but Dodo Thermo Fleece stands out for its performance and eco-friendly materials.
🔹 Step 4: Lining & Finishing
Finish your interior with a smooth, professional look using 4-way stretch automotive carpet.
How to do it:
Spray both the carpet and surface with high-temperature adhesive.
Start from one side and gently stretch around corners.
Trim edges neatly for a seamless finish.
Pro Tip: Choose a darker colour for a premium appearance and low maintenance.
