Aerogel strips are supplied in 2 versions:
Encapsulated - 10mm Aerogel strips, 2.4M long fully encapsulated in polyethelene for added protection and durability. It is self adhesive.
Non - Encapsulated - 10mm Aerogel strips, 2.4M long, with no polyethelene. It is non-adhesive. Specifically made for applications where enhanced fire performance is required, allowing the material to achieve a better fire classification (e.g., A1 non-combustible, depending on the full product build-up and certification).
Proctor Spacetherm Cold Bridge Strip (CBS) is a high-performance solution developed by the Proctor Group to address the critical issue of thermal bridging in modern construction. This specialised product is designed to prevent cold bridging where insulation continuity is difficult to achieve, particularly in timber or steel frame structures.
The strip is basically Spacetherm aerogel insulation—a market-leading material renowned for its superior thermal properties. It is a 10mm thick aerogel insulation, supplied in 2.4M long thin strips.
By using Spacetherm aerogel insulation encapsulated in this robust facing, the strip effectively blocks heat loss through structural members.
Spacetherm CBS is an ideal choice for architects and builders trying to reduce cold bridging without adding significant thickness to the wall or floor buildup. Whether used in timber and steel assemblies, the cold bridge strip prevents the transfer of cold through the structural component or element. It is a versatile addition to any insulation supplies list, offering a practical solution for the prevention of cold bridging in both new builds and retrofits.
Key Features
- Advanced Core Material: Uses 10mm Spacetherm aerogel insulation with an ultra low thermal conductivity of 0.015 W/mK (Standard), ensuring maximum thermal efficiency with minimal thickness.
- Versatile Sizing: While standard sizes are available, upon request the Spacetherm CBS can be customised. It comes in a variety of widths to suit different stud sizes and structural needs.
- Protective Encapsulation: The core is encapsulated in polyethylene (also referred to as aerogel insulation encapsulated in polyethelene in some specifications), which protects the aerogel during the design and build phase.
- Targeted Performance: Specifically designed to prevent cold bridging in areas where standard insulation cannot reach, ensuring the element of a structure remains thermally secure.
