INEOS Grenadier Interior Insulated Window Covers
INEOS Grenadier Interior Insulated Window Covers
These are interior window covers cut specifically for the INEOS Grenadier — not a universal kit trimmed to fit. Each panel matches the shape of the Grenadier's glass, so it sits flush against the window instead of sagging or leaving gaps. They mount with suction cups: press them on, peel them off, store them flat. No adhesive, no brackets, no residue.
Coverage is sold per zone so you only buy what you need: front driver and passenger doors, mid driver and passenger doors, or the rear cargo-area windows. Pick your insulation level per panel too — go non-insulated for sun and privacy, closed-cell foam for moderate temperature control, or Havelock wool for the most thermal regulation when you're parked in real cold or real heat. The glass-facing side is black by default, so from outside the truck the covers read like tinted glass rather than a "someone's in here" billboard.
Eleven exterior colors are on the menu, from blackout-discreet to high-vis. Every set is USA made and carries a lifetime warranty.

Use cases
Owners run them parked at winter-sports lots to keep the cabin from freezing, then flip the same set to summer duty so the truck doesn't bake in the sun. They also knock down road noise on long highway stretches and give you blackout privacy for sleeping in the rig or stowing gear out of sight.

Do these fit my INEOS Grenadier?
Yes — they're cut specifically for the Grenadier's window shapes, not a universal panel. They are not designed for other vehicles.
Which windows do they cover, and do I have to buy the whole set?
Coverage is sold per zone: front doors, mid doors, or rear cargo-area windows. Buy only the zones you want to cover.
Which insulation level should I choose?
Non-insulated handles privacy and sun blocking. Closed-cell foam adds moderate temperature control. Premium Havelock wool gives the most thermal regulation for parking in real cold or real heat.
How do they stay in place?
They mount with suction cups — press them onto the glass to install, peel them off to remove, and store them flat. No adhesive or hardware, so there's no residue left behind.
