Why Insulate a Ford Transit Custom?

Insulating your Ford Transit Custom is essential for controlling temperature, reducing noise, and maintaining a dry, comfortable space. Proper insulation stops heat loss in winter, blocks radiant heat in summer, and prevents condensation that leads to rust and mold.

By combining thermal insulation and sound deadening, you can dramatically improve interior comfort, especially for camper van conversions, work vans, and daily drivers.

 

What You’ll Need

- **10mm Closed Cell Foam** (GlassMAT XR): Reflective, thermal and moisture resistant. Shop 10mm Closed Cell Foam

- **PeaceMAT XR Butyl Sheets**: Reduces road noise, panel rattle, and engine vibrations. Shop Van Sound Deadening

- **Silver Foil Tape**: Seals edges, adds vapour barrier. Shop Aluminium Tape

- **Roller Tool**: Ensures firm adhesion on curved metal surfaces. Shop Sound Deadening Roller

 - **Knife and Cutting Mat**: For clean material cuts along ribs and angles.

 

Step-by-Step Guide

1. **Prep the surfaces**: Clean the interior metal panels using alcohol wipes to remove oil, dirt, and dust.

2. **Apply PeaceMAT XR on large metal panels**: This butyl layer dampens vibration and stops drumming from the van body.

3. **Layer the 10mm GlassMAT XR over the butyl**: Adds both thermal insulation and acoustic absorption.

4. **Seal all joints with silver foil tape**: Creates a vapor barrier that helps manage condensation.

5. **Finish with lining/carpeting**: Adds comfort and makes the van interior look great.

Why Use Our Products vs Cheap Online Rolls?

• Cheap foam products break down over time and absorb moisture, leading to mold and rust.

• Our GlassMAT and PeaceMAT ranges are designed specifically for vehicles: fire-resistant, closed-cell, and self-adhesive.

• Every roll is density and thickness certified — no guessing or shrinkage.

• Tools like rollers and foil tape ensure tight fits that cheap insulation won't match.

Tools and Installation Tips

Using a proper application roller avoids air gaps under insulation — crucial for thermal performance.

Take time to cut each piece cleanly with a fresh blade for straight edges along ribs and structural contours.

Work from the bottom up and use pieces slightly larger than your panel to trim flush after application.
