An empty van is a thin metal box that drums on the highway, bakes in the sun and goes cold overnight. Kool Wrap van insulation kits pair sound deadener with 10mm foil-faced Van Liner so the panels stop ringing and the heat stops moving through them.
An empty van is a thin metal box that drums on the highway, bakes in the sun and goes cold overnight. Kool Wrap van insulation kits pair sound deadener with 10mm foil-faced Van Liner so the panels stop ringing and the heat stops moving through them.
Good van insulation deals with three problems: panel vibration, heat moving through the metal, and radiant heat from the sun and road. Each layer handles one of them.
| Surface | Sound deadener | Insulation | Notes |
|---|---|---|---|
| Floor | Cover 100% of the floor | Your floor insulation or underlay, then the subfloor | If exhaust heat comes through, fit a 5mm heavy duty heat shield to the underside |
| Walls | Centre of each panel, about 20 to 30% coverage | Van Liner over the full panel | Tape every join with aluminium foil tape |
| Roof | Centre of each panel, about 20 to 30% coverage | Van Liner over the full panel | Work in manageable sections overhead |
| Doors and wheel arches |
Outer skins and arch tubs | Van Liner where the trim clears it | Check window and lock mechanisms still move freely |
For exhaust heat through the floor, see our 5mm heavy duty heat shield.
Every kit includes Kool Wrap sound deadener, 10mm Van Liner and a free application roller.

Condensation forms when warm, moist air inside the van meets cold bare metal. Covering the metal with closed-cell foam and taping the joins cuts down the cold surfaces where moisture forms. Ventilation still matters, especially if you cook or sleep inside.
Noise drops because the deadener stops the panels resonating, and the foam liner absorbs some of what’s left. Heat control works both ways. The liner slows heat getting in on a hot day and holds warmth in on a cold night.
For roof or wall areas you won’t cover with Van Liner, foil bubble insulation blocks up to 95% of radiant heat. Tape its joins to keep the moisture barrier intact.
Most owners fit a kit themselves with scissors, a sharp knife, the supplied roller and a degreaser. Strip the panels, clean and dry the metal, apply the deadener, then the Van Liner, and tape the joins. Our step-by-step van insulation guide covers walls, roof and floor.
It reduces it. Closed-cell foam doesn’t absorb water, and covering the cold metal with a foil-faced liner cuts down the surfaces where condensation forms. Tape the joins with aluminium foil tape and keep the van ventilated, especially when cooking or sleeping inside.
Most of the drumming and road noise in an empty van comes from large, thin metal panels vibrating. Sound deadener stops that vibration, and the foam liner absorbs some of the remaining noise. The result depends on the van, the tyres and how much of the van you cover.
Yes. The deadener and Van Liner are self-adhesive and cut with scissors. You need a degreaser, scissors, a sharp knife and the supplied roller. A professional fitter makes sense if you’re also having the van lined and fitted out.
Pick by wheelbase and roof height. Kit 1 suits small vans and 4WDs, and Kit 6 suits extra-long, high-roof vans. Our kit table lists the sound deadener and Van Liner coverage in each kit. If you’re between sizes, call 1300 44 33 34.
For a quiet van, yes. They do different jobs. Sound deadener stops the metal panels vibrating. The Van Liner insulates against heat and cold. Every Kool Wrap van kit includes both.
Yes. The deadener and Van Liner cut to fit, so they suit most vans, including the Toyota HiAce, Ford Transit, Mercedes Sprinter and Renault Trafic.
