Comfort in summer and winter for your Toyota Proace L1H1: 22 m² of Armaflex ChezMoi

Keep the warmth in during winter and limit heat build-up in summer in a Toyota Proace L1H1: that’s the job of Armaflex ChezMoi, which insulates the metal panels against both cold and heat. This kit brings together quantities calculated for the Proace L1H1: 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.

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

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. Its A+ rating (ISO 16000, VOC-free) and Microban® antimicrobial treatment integrated into the material matter in a space where you sleep. Its fire performance complies with the FMVSS automotive standard, and the manufacturer guarantees the material for 10 years.

The kit is easy to use: apply the 10 mm insulation to the floor and structural posts, the 19 mm insulation to the walls and ceiling, the Tape to seal the joins and the Cleaner to clean the metal panels before installation.

Armaflex ChezMoi 19 mm: insulate the walls and ceiling

The 19 mm insulation is the standard thickness for large areas. It provides the most insulation where space allows: on 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: insulate the floor and structural posts

The 10 mm insulation fits where space is tight: the floor, deep reinforcements, wheel arches and structural posts. It preserves headroom while insulating the metal panels. 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 the insulation sheets to limit thermal bridging, while the Cleaner degreases the metal panels 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: 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 L1H1

The kit is sized for the load area of a Toyota Proace L1H1 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 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 area covered by the kit.

Because the closed cells of Armaflex ChezMoi already act as a vapour barrier, no additional vapour control layer is needed.

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

How do I install the Armaflex ChezMoi kit in a Toyota Proace 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 panels. Identify the areas to insulate. If you plan to fit wooden interior panels, install your fixing battens first.
2. Clean the panels before installation. Soak a clean cloth with Cleaner and wipe down all the metal panels: they 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 dimensions of each area onto the non-adhesive side of the insulation, starting with the floor and structural posts (10 mm), then the walls and ceiling (19 mm).
4. Cut to size. Put on the gloves included free and cut the insulation sheets to shape with the utility knife supplied in the kit, or with an Armacell knife kit if you prefer. The foam cuts cleanly.
5. Stick in place. Peel off the backing film as you go, pressing the insulation sheet onto the metal panel from the centre outwards to push out the air.
6. Seal the joins. Apply Tape over each join between two insulation sheets to limit thermal bridging.

Kit technical 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 Toyota Proace L1H1

How can I tell whether my Proace is an L1H1?

The Proace 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 side of Armaflex ChezMoi sticks directly to the metal panels. The Cleaner is used only to degrease them so the adhesive bonds properly.

Is this kit suitable for a Toyota Proace Verso?

It is designed for a panel van Proace being converted into a campervan. The Toyota Proace Verso is a passenger version with windows and interior trim, 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 conditions?

Yes, you can layer two thicknesses 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 compliant 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 each have their own product page, with the same quantities. See the Citroën Jumpy XS kit and the Peugeot Expert L1H1 kit.

Complete the insulation and interior finish of your Toyota Proace L1H1

This kit insulates the van’s metal panels in one go. For additional insulation using eco-friendly 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 wooden interior panels for the Toyota Proace from 2016 onwards: side wall panels, ceiling panels and flooring. 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 van lining felt.
