Isolate your L3H3 van once and for all, without unpleasant surprises.
The bare sheet metal of a van accumulates thermal bridges: it radiates cold in winter, stores heat in summer and promotes condensation — and therefore corrosion. This Armaflex AF kit solves the problem with quantities already calculated for an L2H2 body (Fiat Ducato, Peugeot Boxer, Citroën Jumper, Renault Master, Mercedes Sprinter, Ford Transit, Renault Trafic and equivalents, up to ~5.40 m). Open the package and install it: everything is included.
What the kit contains
-
Walls and ceiling — choose between: 3 rolls of Armaflex AF 19 mm (18 m²) for the standard version, or 4 rolls of Armaflex AF 25 mm (16 m²) for reinforced insulation.
-
Floor, pillars and wheel arches — 1 roll of Armaflex AF 10 mm (10 m²), thinner and more flexible to follow uneven surfaces.
-
Joints and finishing — 2 rolls of 15 m Armaflex adhesive tape to seal every joint and ensure vapour tightness.
-
Preparation — 1 L container of Cleaner, enough to degrease the entire interior before bonding.
Why Armaflex AF
Its closed-cell structure blocks the migration of water vapour (μ ≥ 10 000): the vapour barrier is integrated into the material, so there is no need to add a separate vapour retarder to the walls and ceiling. Thermal conductivity is among the lowest for a flexible insulation material (λ ≈ 0.033 W/(m·K)), with integrated Microban® anti-mould treatment for the product's entire service life, self-extinguishing material and A+ air quality. It does not settle, is unaffected by moisture or mould, and requires no maintenance once installed. 10-year manufacturer's warranty.
19 mm or 25 mm?
19 mm is the market standard for a Furgone: it offers an excellent performance-to-thickness ratio while preserving interior space. 25 mm takes insulation up a notch for those who live aboard all year round or face extreme cold, at the cost of a few millimetres of interior wall space.
Installation in 4 steps
- First install battens and mechanical fixings — Armaflex must be pressed against them, never compressed beneath the lining.
- Degrease the sheet metal with Cleaner, from top to bottom, on a clean, dry surface.
- Remove the backing 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.
