How Metric is built

2-inch insulated aluminum wall panels with a closed-cell EPS foam core — technology originally developed for the NASA Space Program, refined by Radiant (Trojan) for over 60 years. Insulates the water (20–40% heating savings), won’t rust, panels flex instead of cracking.

Install types

Every shape works in every install type. You pick the size — we pick the install approach for your lot.

Coping (edge finishing)

Standard 2″ PVC — white or grey. Included.

Metric Premium — 4″ bullnose exterior.

Rectangle & Emerald patented — structural.

5/4 Deck — clean edge for wood/composite decks.

Concrete Receptor — poured concrete deck.

Aluminum paver — single or double track.

Interior finish & warranty

Reinforced mosaic vinyl liners in multiple patterns, rated 15–25 years. Replacement runs $4,500–$8,500 — a fraction of $6,000–$15,000 gunite resurfacing every 10–15 years.

Non-prorated, fully transferable lifetime warranty on the aluminum panel structure. Transfers to new owner if you sell.

Compatible with everything we install on gunite
