GRP Insulated Water Tank
GRP insulated water tanks are designed to maintain water temperature while providing durable and hygienic water storage.

Product Overview
GRP insulated water tanks are constructed using Glass Reinforced Plastic (GRP) panels combined with thermal insulation layers to reduce heat transfer and maintain stable water temperature. These tanks are widely used where water temperature control is important, such as chilled water systems or hot climate environments.
The insulation layer, commonly made from polyurethane foam, helps reduce heat gain or loss and protects stored water from external temperature changes while ensuring long-term durability and corrosion resistance.


Key Features
- Thermal insulation layer helps maintain stable water temperature
- Durable GRP construction resistant to corrosion and harsh weather
- Hygienic interior surface suitable for potable water storage
- Modular panel design for flexible tank sizing
- UV-resistant exterior suitable for outdoor installations
- Low maintenance with long operational lifespan
GRP insulated tanks combine structural strength with thermal efficiency, making them suitable for demanding environmental conditions.
10 Years of Assured Protection
Durable GRP insulated water tanks designed for long-lasting performance, backed by a 10-year warranty for reliable temperature-controlled water storage.

Frequently Asked Questions?
What is a GRP Insulated Water Tank?
A GRP Insulated Water Tank is a Glass Reinforced Plastic sectional tank fitted with thermal insulation panels, designed to maintain safe water temperatures in extreme heat or cold environments.
Why is insulation important in a GRP water tank?
In high-temperature climates, uninsulated tanks allow stored water to overheat, accelerating bacterial growth. Insulated GRP panels keep water cooler and safer, even under direct year-round sun exposure.
What insulation thickness options are available?
Atlas AlSharq offers 25mm insulation for standard thermal protection and 50mm for extreme heat, rooftop installations, and industrial process water applications.
Can a GRP insulated tank store both hot and cold water?
Yes. GRP insulated tanks maintain cool drinking water in hot climates and retain heat for solar thermal systems, hot water storage, and industrial process water applications.
Does insulation affect the tank’s structural strength?
No. Insulation panels are bonded to the exterior of the GRP structure without affecting load-bearing capacity, watertight integrity, or the food-grade interior surface.
