Insulate your L2H2 van once and for all, with no unpleasant surprises.
The bare sheet metal of a van creates thermal bridges: it radiates cold in winter, stores heat in summer, and encourages condensation — and therefore corrosion. This Armaflex AF kit solves the problem with quantities already calculated for an L2H2 vehicle (Fiat Ducato, Peugeot Boxer, Citroën Jumper, Renault Master, Mercedes Sprinter, Ford Transit, Renault Trafic and equivalents, up to approximately 5.40 m). Open the package and install it: everything is included.
What the kit contains
-
Walls and ceiling — choose from: 3 rolls of 19 mm Armaflex AF (18 m²) for the standard version, or 4 rolls of 25 mm Armaflex AF (16 m²) for reinforced insulation.
-
Floor, pillars and wheel arches — 1 roll of 10 mm Armaflex AF (10 m²), thinner and more flexible to follow contours.
-
Joints and finishing — 2 rolls of 15 m Armaflex adhesive tape to seal every joint and ensure vapor-tightness.
-
Preparation — 1 L container of Cleaner, enough to degrease the entire interior before bonding.
Why Armaflex AF
Its closed-cell structure prevents water vapor migration (μ ≥ 10,000): the vapor barrier is integrated into the material, so there is no need to add a separate vapor retarder to the walls and ceiling. It offers one of the lowest thermal conductivities among flexible insulation materials (λ ≈ 0.033 W/(m·K)), integrated lifelong Microban® mold protection, self-extinguishing properties, and A+ indoor air quality. It does not settle, is resistant to moisture and mold, and requires no maintenance once installed. 10-year manufacturer's warranty.
19 mm or 25 mm?
19 mm is the market standard for a Campervan: an excellent performance-to-thickness ratio that preserves interior space. 25 mm takes insulation up a notch for those who live aboard year-round or face severe cold, at the cost of a few millimeters of interior wall space.
Installation in 4 steps
- Install battens and mechanical fixings first — Armaflex should be pressed against them, never compressed beneath the lining.
- Degrease the sheet metal with Cleaner, working from top to bottom, on a clean, dry surface.
- Remove the film and apply: 19 or 25 mm to the walls and ceiling, 10 mm to the floor, pillars and wheel arches.
- Seal all joints with adhesive tape — a single exposed spot is enough to create a cold bridge.
