Step-by-Step Guide to Insulating Your Campervan for Winter

Step-by-Step Guide to Insulating Your Campervan for Winter

Whether you're preparing for a chilly road trip across the UK or planning to live off-grid in your van this winter, insulating your campervan properly is the key to staying warm, reducing condensation, and improving overall comfort.

In this guide, we’ll walk you through how to fully insulate your van for winter using high-quality, easy-to-install products available at CampervanInsulation.co.uk.

🔍 Why Insulation Matters in Winter

  • Reduces Heat Loss – Keep the warmth inside and save money on heating.

  • Prevents Condensation – Avoid damp, mould, and long-term damage.

  • Improves Comfort & Noise – Create a calmer, quieter living space.

✅ What You’ll Need

Here’s a complete insulation setup recommended for winter use:

🧰 Tools You’ll Need

  • Sharp knife or insulation scissors

  • Roller or squeegee for butyl/MLV mats

  • Spray adhesive or double-sided tape (for insulation batting)

  • Gloves and a tape measure

  • Optional: vapour barrier for added sealing

🪚 Step-by-Step Installation Guide

1. Prepare Your Surfaces

  • Remove all trims, panels, flooring, and clean any dust or residue.

  • Make sure metal areas are dry and rust-free.

  • Mark areas where wiring or access panels will stay clear.

2. Start by Sound Deadening the Floor & Wheel Arches

  • Apply PeaceMAT XR Butyl Rubber Mat directly onto metal surfaces.

  • Roll firmly into place using a seam roller—this reduces resonance and improves heat retention.

3. Add Thermal Layer to Floor

  • Stick 6mm closed cell foam directly on top of the Butyl layer.

  • This creates a barrier that stops cold bridging and provides extra comfort underfoot.

  • For extreme cold, finish with 2mm MLV or 4mm floor acoustic composite.

🛒 Suggested: 4mm Campervan Floor Composite (Rubber + Foam + Foil)

4. Insulate Walls and Ceiling with ABSoft Dacron

  • Cut and place 25mm or 50mm ABSoft polyester insulation between the van ribs.

  • This soft, hydrophobic material traps heat and won’t absorb moisture.

  • Use spray adhesive or clips to secure. No itchy fibres, easy to work with.

5. Install Reflective Barrier Layer (Optional but Recommended)

  • Apply ThermoPro Foil-Backed Insulation (8mm) over panel gaps and framing.

  • Acts as a vapour barrier and radiant heat reflector.

  • Adhesive backing makes install quick.

6. Seal Gaps & Odd Spaces with Hydroweld

  • Use 15mm Hydroweld acoustic blanket to fill cavities like above windows, pillars, and bulkheads.

  • Hydrophobic and tightly-woven, it won’t sag or go mouldy.

7. Rebuild Your Interior

  • Replace wall panels, fit your flooring, and trim edges.

  • Install a vapour barrier if extra moisture control is needed.

  • Add thermal window covers or curtains for even better protection.

❄️ Bonus Tips for Winter Vanlife

  • Always insulate the cab bulkhead – 30–40% of heat is lost here.

  • Use thermal blinds or insulated curtains for window coverage.

  • Add a roof vent (with closeable cover) to prevent trapped moisture buildup.

  • If using heaters like diesel or propane, install a carbon monoxide alarm.
