28 m² of Armaflex ChezMoi calculated to insulate your Peugeot Boxer L1H2

This kit brings together all the Armaflex ChezMoi you need to insulate a Peugeot Boxer L1H2 for a campervan conversion: 1 roll of 10 mm, 3 rolls of 19 mm, 3 rolls of Tape and 1 bottle of Cleaner, with a pair of gloves and a utility knife included free. The quantities are calculated for the Boxer L1H2: order everything at once, with no need to estimate the area or add extra products.

Armaflex ChezMoi is an elastomeric foam made in Europe using Armacell technology. Its self-adhesive side sticks directly to cleaned metal, with no glue to add. The closed cells also act as a vapour barrier (μ> 7,000): there’s no separate vapour control layer to fit, and less condensation on the metal.

With a thermal conductivity of 0.035 W/(m·K) and a service temperature range of −50 °C to +85 °C, it insulates against both cold and heat, whether you turn your Boxer into a campervan, a work van or a motorhome. Its A+ rating (ISO 16000, VOC-free) and the Microban® antimicrobial treatment integrated into the material matter in a space where you sleep. Its reaction to fire meets the FMVSS automotive standard, and the manufacturer guarantees the material for 10 years.

The kit is straightforward to use: the 10 mm insulation is for the floor and uprights, the 19 mm for the walls and ceiling, Tape seals the joints, and Cleaner cleans the metal before fitting.

Armaflex ChezMoi 19 mm: insulate the walls and ceiling

The 19 mm insulation is the standard thickness for large surfaces. It provides the most insulation where space allows: the Boxer’s side walls, doors and ceiling. The kit contains 3 rolls, covering 18 m².

• Thickness: 19 mm
• Pack size: 6 m² roll (6 m × 1 m)
• Thermal conductivity: λ = 0.035 W/(m·K) at 0 °C
• Vapour barrier: integrated, μ> 7,000
• Service temperature: −50 °C to +85 °C
• Reaction to fire: FMVSS automotive standard
• Air quality: A+ rating (ISO 16000), VOC-free
• Antimicrobial treatment: Microban® integrated into the material
• Warranty: 10 years (manufacturer)

Armaflex ChezMoi 10 mm: insulate the floor and uprights

The 10 mm insulation fits where space is tight: the floor, deep structural reinforcements, wheel arches and uprights. It insulates the metal while preserving headroom. The kit contains 1 roll, covering 10 m².

• Thickness: 10 mm
• Pack size: 10 m² roll (10 m × 1 m)
• Thermal conductivity: λ = 0.035 W/(m·K) at 0 °C
• Vapour barrier: integrated, μ> 7,000
• Service temperature: −50 °C to +85 °C
• Reaction to fire: FMVSS automotive standard
• Air quality: A+ rating (ISO 16000), VOC-free
• Antimicrobial treatment: Microban® integrated into the material
• Warranty: 10 years (manufacturer)

Tape, Cleaner, gloves and utility knife: preparation, cutting and joints

Tape seals the joints between sheets to limit thermal bridging, while Cleaner degreases the metal for good adhesion. The kit contains 3 rolls of Tape, providing 45 m of tape, and 1 bottle of Cleaner. A pair of gloves and a utility knife are included free for handling and cutting the insulation.

• Tape: 15 m × 50 mm adhesive roll, 3 rolls in the kit
• Cleaner: solvent-based Armaflex cleaner, 1 L bottle, applied with a cloth, 1 bottle in the kit
• Gloves: 1 pair, included free with the kit
• Utility knife: 1, included free with the kit

Compatibility: Peugeot Boxer L1H2

The kit is sized for the load area of a Peugeot Boxer L1H2 panel van (from 2006 onwards): 2,670 mm long, 1,870 mm wide and 1,932 mm high, with a width of 1,422 mm between the wheel arches. These dimensions are a guide: measure your vehicle before fitting, especially if it has already been converted.

Please note: The partition separating the cab is not included in the areas covered by the kit.

Because the closed cells of Armaflex ChezMoi already act as a vapour barrier, there’s no need for a separate vapour control layer.

The Boxer L1H2 shares its bodywork with the Fiat Ducato and Citroën Jumper: see the Fiat Ducato L1H2 and Citroën Jumper L1H2 kits. Other Boxer sizes: L1H1, L2H1, L2H2, L3H2 and L3H3.

How do I fit the Armaflex ChezMoi kit in a Peugeot Boxer L1H2?

Armaflex ChezMoi is self-adhesive: it can be fitted without glue using a few simple tools and requires no specialist skills. Just follow the steps in order. Our blog article on fitting Armaflex explains each step in detail.

1. Prepare the surfaces. Identify the areas to insulate. If you plan to add wood panelling, fit your fixing battens first.
2. Clean the surfaces before fitting. Dampen a clean cloth with Cleaner and wipe down all the metal: it must be clean and degreased for the adhesive to bond. Cleaner contains a solvent and gives off fumes: wear a mask and work outdoors if possible.
3. Mark out. Transfer the dimensions of each area onto the non-adhesive side of the insulation, starting with the floor and uprights (10 mm), then the walls and ceiling (19 mm).
4. Cut to size. Put on the gloves included free and cut the sheets to shape with the utility knife in the kit, or with an Armacell knife kit if you prefer. The foam cuts cleanly.
5. Stick in place. Peel off the protective film as you go, pressing the sheet onto the metal from the centre outwards to push out any air.
6. Seal the joints. Apply Tape over every joint between two sheets to limit thermal bridging.

Kit technical specifications

The kit also contains 3 rolls of Tape (15 m × 50 mm), 1 bottle of solvent-based Cleaner (1 L), plus 1 pair of gloves and 1 utility knife included free.

Frequently asked questions about insulating a Peugeot Boxer L1H2

How can I tell if my Boxer is an L1H2?

The size combines length (L1, L2, L3) and roof height (H1, H2, H3). Measure the usable length of the load floor: around 2,670 mm for an L1, 3,120 mm for an L2 and 3,705 mm for an L3. Then measure the interior height: around 1,662 mm for an H1, 1,932 mm for an H2 and 2,172 mm for an H3. For an L1H2, expect 2,670 mm by 1,932 mm.

Do I need DIY experience to fit this kit?

No. The insulation is self-adhesive and can be cut with the utility knife included free in the kit: clean, cut, stick, then seal the joints with Tape. The six steps in the installation section are all you need, and the video shows you how.

Do I need to add glue?

No, the self-adhesive side of Armaflex ChezMoi sticks directly to the metal. Cleaner is only used to degrease it so the adhesive bonds properly.

Is this kit suitable for a Boxer-based motorhome?

It is designed for an L1H2 Boxer panel van being converted into a campervan or van-based motorhome. For an integrated or coachbuilt motorhome, the living area has different dimensions: measure it before deciding how much Armaflex you need.

Can I double the thickness for very cold conditions?

Yes, you can layer two sheets in exposed areas if you drive in very cold conditions. You’ll need to add rolls of Armaflex ChezMoi 19 mm to the kit.

Armaflex ChezMoi or Armaflex AF: what’s the difference?

Armaflex ChezMoi is the successor to Armaflex AF for vehicle conversions: the same self-adhesive foam, with a reaction to fire that meets the FMVSS automotive standard. Our article compares the two ranges point by point.

Is there a kit for a Ducato or Jumper of the same size?

Yes: the Fiat Ducato and Citroën Jumper each have their own L1H2 product pages. See the Fiat Ducato L1H2 kit and the Citroën Jumper L1H2 kit.
