Everything needed to insulate a Peugeot Expert L1H1: 22 m² of Armaflex ChezMoi, Tape and Cleaner

One kit to insulate a Peugeot Expert L1H1 campervan: Armaflex ChezMoi, Tape for the joins and Cleaner to prepare the metal bodywork, all in quantities calculated for the Expert L1H1. The kit contains 1 roll of 10 mm insulation, 2 rolls of 19 mm insulation, 2 rolls of Tape and 1 Cleaner, with a pair of gloves and a utility knife included free. Order everything in one go, with no extra items to add.

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

With a thermal conductivity of 0,035 W/(m·K) and an operating range of −50 °C to +85 °C, it insulates against both cold and heat, whether your Expert becomes a campervan or remains a work van. The A+ rating (ISO 16000, VOC-free) and Microban® antimicrobial treatment integrated into the material matter in a space where you sleep. Its fire performance meets the FMVSS automotive standard, and the manufacturer guarantees the material for 10 years.

The kit is straightforward to use: the 10 mm insulation goes on the floor and structural uprights, the 19 mm on the walls and ceiling, Tape seals the joins, and Cleaner cleans the metal bodywork before installation.

Armaflex ChezMoi 19 mm: insulating the walls and ceiling

The 19 mm thickness is the standard choice for large areas. It provides the most insulation where space allows: the Expert’s side walls, doors and ceiling. The kit contains 2 rolls, covering 12 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
• Operating temperature: −50 °C to +85 °C
• Fire performance: 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: insulating the floor and structural uprights

The 10 mm insulation fits where space is tight: the floor, deep structural reinforcements, wheel arches and uprights. It preserves headroom while insulating the metal bodywork. 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
• Operating temperature: −50 °C to +85 °C
• Fire performance: 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 sealing joins

Tape seals the joins between sheets to limit thermal bridging, while Cleaner degreases the metal bodywork for good adhesion. The kit contains 2 rolls of Tape, providing 30 m of tape, and 1 Cleaner. A pair of gloves and a utility knife are included free for handling and cutting the insulation.

• Tape: 15 m × 50 mm self-adhesive roll, 2 rolls in the kit
• Cleaner: solvent-based Armaflex cleaner, 1 L bottle, applied with a cloth, 1 in the kit
• Gloves: 1 pair, included free with the kit
• Utility knife: 1, included free with the kit

Compatibility: Peugeot Expert L1H1

The kit is sized for the load area of a Peugeot Expert L1H1 panel van (Compact length), from 2016 onwards: 2 162 mm long, 1 636 mm wide and 1 397 mm high, with 1 258 mm between the wheel arches. These measurements are indicative: measure your vehicle before installation, 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 is no need for a separate vapour control layer.

The Expert L1H1 shares its bodywork with the Citroën Jumpy XS and Toyota Proace L1H1: see the Citroën Jumpy XS and Toyota Proace L1H1 kits. Other Expert sizes: L2H1 and L3H1.

How do I install the Armaflex ChezMoi kit in a Peugeot Expert L1H1?

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

1. Prepare the surfaces. Identify the areas to insulate. If you plan to fit wood panelling, install the fixing battens first.
2. Clean the surfaces before installation. Dampen a clean cloth with Cleaner and wipe down all the metal bodywork: 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. Put on the gloves included free and cut the sheets to shape with the utility knife supplied in the kit, or with an Armacell knife set if you prefer. The foam cuts cleanly.
5. Stick down. Peel away the protective film gradually, pressing the sheet onto the metal from the centre towards the edges to push out air.
6. Seal the joins. Apply Tape over every join between two sheets to limit thermal bridging.

Kit specifications

The kit also contains 2 rolls of Tape (15 m × 50 mm), 1 solvent-based Cleaner (1 L bottle), plus 1 pair of gloves and 1 utility knife included free.

Frequently asked questions about insulating a Peugeot Expert L1H1

How can I tell whether my Expert is an L1H1?

The Expert panel van comes in three lengths (Compact, Standard and Long), all with the same roof height: these correspond to our L1H1, L2H1 and L3H1 sizes. Measure the usable length of the load floor: approximately 2 162 mm for an L1H1, 2 512 mm for an L2H1 and 2 862 mm for an L3H1. The usable height, around 1 397 mm, is the same for all three.

Do I need DIY experience to install 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 joins 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 bodywork. Cleaner is only used to degrease the metal so the adhesive bonds properly.

Is this kit suitable for a Peugeot Traveller?

It is intended for an Expert panel van being converted into a campervan. The Peugeot Traveller, a glazed passenger version with its interior already fitted, does not have the same areas to insulate: measure the areas you need to cover before choosing how much Armaflex to buy.

Can I double the thickness for very cold weather?

Yes, you can layer two sheets in exposed areas if you drive in very cold conditions. You will need to add extra 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 fire performance to the FMVSS automotive standard. Our article compares the two ranges point by point.

Is there a kit for a Jumpy or Proace of the same size?

Yes: the Citroën Jumpy and Toyota Proace have their own listings, with the same quantities. See the Citroën Jumpy XS kit and the Toyota Proace L1H1 kit.

Complete the insulation and finish of your Peugeot Expert L1H1

This kit insulates the metal bodywork in one go. If you want to go further with eco-responsible materials, explore our campervan insulation kits.

For the floor, add a layer of 4 mm cork underlay on a roll beneath your floor covering: it reduces the feeling of a cold floor and reduces vibrations and road noise. Explore the full cork insulation range.

Once the insulation is installed, Heode offers wood panelling for the Peugeot Expert from 2016 onwards: side wall panels, ceiling panels and flooring. Explore all our panelling for the Peugeot Expert.

For the wall finish, start with a sample of stretch lining felt: choose the colour (light grey, dark grey, anthracite, black or beige) in your van before ordering the van lining felt.
