Balmoral Elastotherm®
High-performance subsea insulation for hot-wet environments
Advanced subsea insulation
Balmoral has manufactured subsea insulation ancillaries for over 45 years, specialising in factory moulded half-shell, housing, clamp and retro-fit options using a variety of material technologies. The company has extensive experience of producing half-shell insulation shrouds in excess of 4m long and up to 650 litres in volume.
Unlike linepipe or cast-in-place insulation, which is designed for hot-dry service, half-shell shrouds, housing, clamp and retro-fit insulation products endure hot-wet service as the cavity between the structure and insulation is flooded with seawater. Balmoral ELASTOTHERM systems have been selected to provide suitable hot-wet performance over a design life of up to 30 years.
Balmoral’s insulation shrouds can be designed to accommodate minimal fluid transfer rates over their service life which is particularly important where a long cool-down rate or target U-value is required.
For products requiring extremely tight geometric tolerances, Balmoral’s in-house machine shop, with an extensive range of 5-axis CNC, vertical borers and milling machines can be used. Keeping the design, project management, moulding, finishing and testing processes in-house, gives full control over the workscope.

Design and testing
Balmoral draws on its extensive engineering experience and comprehensive R&D programmes to offer FEA or CFD analysis of project design parameters to ultimately provide the most cost effective coating solutions. Early dialogue with clients means that optimum fit for purpose, through life solutions can be identified and implemented.
New, state-of-the-art, technical and subsea test centre facilities offer extensive laboratory and test capabilities to ensure all materials meet stringent industry requirements.
Applications and advantages
ELASTOTHERM insulation systems are suitable for depths up to 7000msw, making them ideal for deep-sea applications where high hydrostatic pressure is a concern
These materials offer excellent performance in hot-wet conditions, with temperature resistance up to 140°C, perfect for subsea environments with high temperatures and moisture
ELASTOTHERM insulation maintains consistent properties for up to 30 years, ensuring durability and reliability for long-term subsea projects
The range includes materials with specific mechanical properties, allowing selection of flexible or rigid options based on application needs, such as installations requiring high strain tolerance during deployment or service
Field-proven, tested and trusted
Balmoral has been the trusted partner for the offshore energy industry for more than 40 years. In that time, we have consistently demonstrated an exemplary track record for safety, and we firmly believe our products have the lowest failure rates in the sector. Customers know they can rely on our longstanding experts and field-proven solutions, based on best-in-class engineering, rigorous product testing and installation.
