Insulate your Toyota Proace L3H1 without glue: 22 m² of self-adhesive Armaflex ChezMoi

To insulate a Toyota Proace L3H1 for conversion into a campervan, this kit brings together self-adhesive Armaflex ChezMoi and everything you need to install it: 1 roll of 10 mm insulation, 2 rolls of 19 mm insulation, 2 rolls of Tape and 1 Cleaner, plus a pair of gloves and a utility knife included free. No glue to buy or spread: the self-adhesive backing sticks directly to cleaned sheet metal. The quantities are calculated for the Proace L3H1, excluding the cab partition.

Armaflex ChezMoi is an elastomeric foam made in Europe using Armacell technology. Its self-adhesive backing sticks directly to cleaned sheet metal, with no additional glue needed. The closed-cell structure also acts as a vapour barrier (μ> 7,000): there is no separate vapour control layer to install, and less condensation 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 you convert your Proace into a campervan or keep it as 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: 10 mm insulation for the floor and pillars, 19 mm for the walls and ceiling, Tape to seal the joins and Cleaner to clean the sheet metal before installation.

Armaflex ChezMoi 19 mm: insulating the walls and ceiling

The 19 mm insulation is the standard thickness for large areas. It provides the most insulation where space allows: the Proace’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
• Guarantee: 10 years (manufacturer)

Armaflex ChezMoi 10 mm: insulating the floor and pillars

The 10 mm insulation fits where space is tight: the floor, deep reinforcement sections, wheel arches and pillars. It preserves headroom while insulating the sheet metal. 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
• Guarantee: 10 years (manufacturer)

Tape, Cleaner, gloves and utility knife: preparation, cutting and sealing joins

The Tape seals the joins between sheets to limit thermal bridging, while the Cleaner degreases the sheet metal for good adhesion. The kit contains 2 rolls of Tape, giving you 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: adhesive roll, 15 m × 50 mm, 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: Toyota Proace L3H1

The kit is sized for the load area of a Toyota Proace L3H1 panel van (Long version) from 2016 onwards: 2,862 mm long, 1,636 mm wide and 1,397 mm high, with 1,258 mm between the wheel arches. These dimensions are indicative: measure your vehicle before installation, especially if it has already been converted.

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

Because the closed-cell structure of Armaflex ChezMoi already acts as a vapour barrier, there is no need for a separate vapour control layer.

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

How do I install the Armaflex ChezMoi kit in a Toyota Proace L3H1?

Armaflex ChezMoi is self-adhesive: it installs 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 walls. Identify the areas to insulate. If you plan to fit wooden interior panels, install your fixing battens first.
2. Clean the walls before installation. Dampen a clean cloth with Cleaner and wipe down all the sheet metal: it must be clean and degreased for the adhesive to bond. The Cleaner contains a solvent and gives off fumes: wear a mask and work outdoors if possible.
3. Mark out. Transfer the measurements for each area onto the non-adhesive side of the insulation, starting with the floor and pillars (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 set if you prefer. The foam cuts cleanly.
5. Stick in place. Peel away the protective film as you go, pressing the sheet onto the metal from the centre outwards to remove trapped air.
6. Seal the joins. Apply Tape over every join between two sheets to limit thermal bridging.

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 Toyota Proace L3H1

How can I tell if my Proace is an L3H1?

The Proace panel van comes in three lengths (Compact, Medium 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, approximately 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. Just follow the six steps in the installation section; the video shows you how.

Do I need to add glue?

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

Is this kit suitable for a Toyota Proace Verso?

This kit is designed for a panel van Proace being converted into a campervan. The Toyota Proace Verso is a glazed passenger version with an existing interior, so it 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 travel in very cold conditions. You will 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 fire performance in accordance with the FMVSS automotive standard. Our article compares the two ranges point by point.

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

Yes: the Citroën Jumpy and Peugeot Expert have their own product pages, with the same quantities. See the Citroën Jumpy XL kit and Peugeot Expert L3H1 kit.

Complete the insulation and interior finish of your Toyota Proace L3H1

This kit insulates the metalwork in one go. 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 our full cork insulation range.

Once the insulation is installed, Heode offers wooden interior panels for Toyota Proace vans from 2016 onwards: side wall panels, ceiling panels and floor panels. Explore all our Toyota Proace interior panels.

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