Use the drop-down to select the model of Promaster van you have.

Note: Includes precut material to cover cargo area ceiling, walls, and doors. If you have windows, you'll have extra pieces. Does not include material for cab area or any portion of the vehicle floor. Does not include material to stuff between beams, fully covered cavities, or partially covered cavities. The Kit focuses on the main large open cavities for 2014+ Ram ProMaster cargo vans.

Compatible with low-roof ProMaster 136" and low roof 159" models, just be aware you will need to cut down the material pieces to fit. Does not include material to stuff between beams, fully covered cavities, or partially covered cavities. The Kit focuses on the main large cavities for 2014+ Ram ProMaster cargo vans.

3M™ Thinsulate™ is a unique non-woven acoustic absorber composed of polyester and polypropylene fibers. The polypropylene fibers are extremely fine, producing a high-energy absorption characteristic with low weight. The polyester fibers are added to strengthen the web, while the scrim protects and contains the fibers. The fine microfibers absorb high frequency noise, and the thicker fibers provide recovery and loft. It is compressible, lightweight, and conformable.

Non-3M Material Specifications(159" option)

Property	Details
Type	PP+PET Bi-Component Acoustic & Thermal Insulation
Fire Resistance	Flame retardant — self-extinguishing after removal from flame
Roll Width	155 cm
Thickness	44 mm
Density	13.6 kg/m³
Thermal Resistance (R-Value)	≈ 1.51 m²·K/W
Sound Insulation	At 600 g/m² and 44 mm, this PP+PET bi-component acoustic cotton achieves a sound absorption coefficient ≥ 0.7 across the 200–2,000 Hz range most relevant to automotive applications. Compared to conventional thin cotton, it delivers approximately 30% better overall noise reduction for low-frequency tire noise and mid-to-high-frequency wind noise, while simultaneously achieving a thermal resistance of 1.51 m²·K/W — combining both acoustic and thermal performance in a single layer.
Lightweight	At the 600 g/m², 44 mm specification, our PP+PET acoustic insulation achieves a density of only approximately 13.6 kg/m³. Without compromising sound absorption or thermal performance, this ultra-lightweight design reduces unit-volume weight by approximately 30% versus competing products, effectively lowering overall vehicle weight and contributing to improved driving range.
Easy to Install	Easily die-cut and heat-sealed. Compatible with a wide range of substrates via thermal bonding or ultrasonic welding.
Mold & Moisture Resistance	Manufactured with PP+PET hydrophobic bi-component fibers for outstanding moisture and water repellency — minimizing moisture absorption and retention. The inorganic fiber matrix provides no nutrient source for mold, effectively inhibiting mold growth and eliminating musty odors. The material remains structurally stable through repeated wet-dry cycles, maintaining consistent sound absorption and thermal insulation performance even under prolonged humid conditions.
