What goes into an Imperium cover.
Every Imperium cover, custom or ready-to-ship, is built to the same specification in Ontario. Here is exactly what that means, so you can judge the value before you buy.
Every cover includes

Heat-sealed vapor barrier
High-density EPS foam wrapped in a heavy-duty vapour barrier, locking out moisture and the “waterlogged cover” failure entirely.

30 oz marine-grade vinyl or DuraTex
A UV- and mildew-resistant exterior built to take sun, snow, and ice without cracking or fading, with double-stitched, reinforced seams. Choose classic marine-grade vinyl or our 1000D DuraTex fabric.

Four locking safety straps
Full locking hardware to secure the cover, support safety, and shrug off wind lift. Standard, not an upgrade.

Reinforced lift handles
Integrated handles on both sides plus a full-perimeter skirt that seals the shell edge and shields the acrylic lip from UV.
What to look for in a hot tub cover
The difference is in the parts you can’t see in a photo. Here is each spec and why it matters, so you can judge the value yourself.
