Hot Insulation – K-Aerogel

Introduction to K-Aerogel Ht-i

Aerogel Blanket for Hot Insulation

K-Aerogel Ht-i is a high performance insulation blanket engineered for demanding industrial applications, including the oil and gas sector, especially LNG systems. It is composed of silica aerogel, the world’s lowest thermal conductivity material, integrated with a glass fibre needle blanket. This advanced insulation solution is designed to perform in extreme temperatures ranging from -50°C to +650°C.

K-Aerogel Ht-i combines exceptional thermal insulation with a suite of performance advantages:

Low thermal conductivity for maximum energy efficiency
Hydrophobic yet vapour permeable to resist moisture while allowing vapour diffusion
Compression resistant and resilient, maintaining its form and performance under pressure
Inorganic and non-combustible, ensuring safety and regulatory compliance
Lightweight and easy to handle, with reduced volume for simplified installation
Environmentally safe, supporting sustainability objectives

With its cutting edge material science and practical benefits, K-Aerogel Ht-i is the ideal choice for applications requiring superior insulation performance in minimal thickness, enabling significant energy savings and operational reliability.

Key Benefits

HYDROPHOBIC YET BREATHABLE

K-Aerogel HT-i repels liquid water while allowing vapor to escape, helping pipes and equipment stay dry for longer periods. It offers exceptional protection against corrosion under insulation (CUI), enhances process stability, and extends the lifespan of your assets.

REUSABLE

K-Aerogel HT-i can be easily removed for inspection and maintenance, then reapplied in its original condition minimizing downtime and eliminating the need to purchase new insulation during routine maintenance cycles.

LESS TIME AND LABOR TO INSTALL

K-Aerogel insulation can be easily cut and shaped to fit complex equipment geometries, tight curvatures, and areas with limited access.

SHIPPING AND WAREHOUSING SAVINGS

Its reduced material volume, high packing density, and low scrap rates help minimize shipping volumes and overall logistics costs.

SIMPLIFIED INVENTORY

Unlike rigid pre-forms like pipe covers or boards, K-Aerogel blanket insulation can be easily customized and kitted to fit virtually any shape or design.

ENVIRONMENTALLY SAFE

K-Aerogel high-temperature insulation is landfill-disposable, shot-free, and contains no respirable fibers ensuring safer handling and simplified disposal.
