İzocam stone wool types comprise more than one standard board. A product used beneath render on a facade differs in form and technical requirements from one placed inside a plasterboard partition, around a ventilation duct or on an industrial pipe operating at high temperatures. Correct selection starts with the application area, followed by comparison of board, pipe section or blanket form, facings and mechanical properties.
What Is İzocam Stone Wool?
Stone wool is a mineral-wool-based insulation material manufactured by melting inorganic raw materials at high temperatures and forming them into fibres. İzocam's current range offers stone wool in board, blanket, preformed pipe section and loose-fill forms according to the intended use. These forms are tailored to needs such as thermal insulation, sound control, acoustic treatment and fire safety.
İzocam declares a general thermal conductivity range of 0,035–0,040 W/mK for its stone wool product group, with a water vapour diffusion resistance factor of approximately μ=1. However, as density, facing, mechanical strength and service temperature may vary by product, purchasing decisions must use the selected product's current technical data sheet rather than general product-group data.
Which İzocam Stone Wool Is Used for Each Application?
| Application area | Suitable product form | Key selection criterion |
|---|---|---|
| Rendered external wall insulation | Manto Stone Wool | Render system compatibility, tensile strength perpendicular to faces and compressive strength |
| Curtain walling and ventilated facades | External Wall Board | Facing option, facade cavity and mechanical fixing |
| Plasterboard partitions and internal walls | Partition Board | Fit between profiles, acoustic infill and resistance to sagging |
| Ventilation and air-conditioning ducts | Stone Wool HVAC Board | Foil facing, external thermal insulation and internal sound control |
| High-temperature industrial pipes | Preformed Stone Wool Pipe Section | Pipe diameter, line temperature, thickness and external protection |
| Boilers, tanks and large-diameter equipment | Industrial Stone Wool Blanket | Flexible wrapping, wire support and operating temperature |
1. Manto Stone Wool: For Rendered External Wall Systems
İzocam Manto Stone Wool is an unfaced stone wool board manufactured for rendered external wall thermal insulation systems. On facades, board thermal performance matters alongside compatibility with adhesive and render layers, tensile strength perpendicular to faces, compressive strength and anchoring behaviour.
This product is considered particularly for insulation projects requiring fire safety, vapour permeability and continuous external insulation together. The substrate must be sound and dry, boards staggered without gaps, and mechanical fixing performed according to project conditions.
Manto Stone Wool and curtain wall insulation boards must not be considered interchangeable. Manto is directly part of a rendered system; curtain walling places separate facade cladding, and often a ventilation cavity, in front of the board.
2. External Wall Board: Behind Curtain Walling
İzocam External Wall Board is used in curtain wall systems behind granite, marble, metal, glass or similar cladding. Alongside unfaced options, aluminium foil or black glass tissue facings may be available according to the project.
Product selection must consider whether cladding joints are open or closed, the ventilation cavity, wind effects, water drainage and mechanical fixing method together. As facing type can affect the board's behaviour under outdoor exposure and its reaction-to-fire class, the quotation and technical data sheet must provide the full product description.
3. Partition Board: Thermal and Sound Control Inside Walls
İzocam Partition Board is used in lightweight partitions with metal or timber supports, wall linings, party walls, stairwells and lift shafts. The main purpose is to fill the wall cavity with suitable mineral wool to reduce heat and sound transmission and contribute to fire safety.
The board must fit between profiles without gaps; its fibre structure must not be damaged through compression, and no openings must be left within the wall. Suitable acoustic insulation tape where profiles contact floors, ceilings and adjoining walls helps reduce structure-borne vibration.
Partition Board is not a surface acoustic panel. It is a system component inside the wall that reduces sound transmission; a separate surface acoustic solution may be needed to control room reverberation time.
4. Stone Wool HVAC Board: In HVAC Ducts
İzocam Stone Wool HVAC Board is used for external thermal insulation of ventilation and air-conditioning ducts or internal sound control according to the system detail. An aluminium foil facing can provide a clean finish and continuity of the vapour control layer in external applications.
Sealing joints, continuity around hangers and flanges, foil tape installation and condensation calculations are as important as board thickness in duct insulation. On ducts carrying cold air, even a small open joint can increase the risk of surface condensation and dripping water.
5. Preformed Stone Wool Pipe Section: On Hot Industrial Lines
İzocam Preformed Stone Wool Pipe Section is a rigid mineral wool product shaped to pipe diameter, used particularly for thermal insulation of industrial pipes operating at high temperatures. Unfaced or aluminium-foil-faced options may be considered according to application conditions.
Knowing the pipe's outside diameter alone is insufficient for correct product selection. Fluid temperature, ambient conditions, target surface temperature, energy-loss limit, outdoor exposure and mechanical protection needs affect thickness calculations. Leaving valves, flanges, elbows and hanger points uninsulated can create significant thermal bridges.
6. Industrial Stone Wool Blanket: On Boilers, Tanks and Large-Diameter Pipes
İzocam Industrial Stone Wool Blanket is a flexible product used on surfaces where flat boards do not easily fit, such as boilers, tanks, process equipment and large-diameter pipes in industrial facilities. The supporting wire mesh helps the blanket wrap curved surfaces and be mechanically fixed.
Blanket selection must consider operating temperature, density, thickness, wire mesh type and the outer cladding system together. Outdoor applications require suitable metal cladding and detail solutions to protect mineral wool from rain, wind and mechanical impacts.
The Difference Between Faced and Unfaced Stone Wool
Unfaced stone wool boards, pipe sections or blankets are used with a plain mineral wool surface according to the system layer placed above. Facings such as aluminium foil, black glass tissue or wire mesh perform different roles in vapour control, surface protection, mechanical support or ease of installation.
Facing selection is more than a visual decision. Some declared properties, including reaction-to-fire class, may change with the facing. İzocam states that according to TS EN 13501-1, unfaced stone wool products are A1-class; where a faced product is used, its complete product declaration must be checked separately.
Which Values Matter When Reading a Technical Data Sheet?
- Declared thermal conductivity: Used together with thickness to assess the product's ability to limit heat transfer.
- Reaction-to-fire class: Must be checked for the complete product construction, including its facing.
- Dimensions and thickness: Must suit profile spacing, system details, pipe diameter or calculated thermal resistance.
- Mechanical properties: Compressive and perpendicular tensile strength matter on facades, load-bearing capacity on roofs, and fixing needs in industry.
- Facing type: The role of foil, glass tissue or wire mesh in the application must be understood.
- Service temperature: Product limits and operating conditions must be compared, particularly on pipes, boilers and process equipment.
- Water absorption and vapour behaviour: Must be assessed alongside layer arrangement in facade, roof and cold service details.
Common Mistakes When Selecting İzocam Stone Wool
- Assuming every stone wool board can be used beneath external insulation render
- Choosing curtain wall and rendered facade products interchangeably
- Considering density alone without checking mechanical declarations and product standards
- Assuming faced and unfaced products have the same fire class
- Determining pipe insulation thickness without line temperature and diameter information
- Neglecting foil and tape continuity on cold ducts
- Omitting protective metal cladding in outdoor industrial applications
Frequently Asked Questions
Can İzocam Manto Stone Wool be used in partition walls?
The product was developed for rendered external wall systems. Partition walls should use Partition Board suited to profile spacing and installation within the wall.
What is the difference between External Wall Board and Manto Stone Wool?
Manto Stone Wool is part of a rendered external wall system. External Wall Board is used in curtain wall or ventilated facade insulation behind separate cladding.
Are all İzocam stone wool products A1-class?
İzocam states that unfaced stone wool products are A1-class. For products with foil, glass tissue or other facings, the complete product's current reaction-to-fire class must be checked in the technical data sheet.
How is stone wool thickness selected?
Thickness is determined according to the building element, climate, target thermal resistance, product thermal conductivity and relevant project calculations. Operating and surface temperatures are also considered in industrial applications.
Are Stone Wool HVAC Board and Preformed Pipe Section used in the same place?
No. HVAC Board is mainly used on rectangular or large-surface ventilation ducts, while Preformed Pipe Section is used on hot industrial pipes in a shape matching their diameter.
Conclusion: Correct İzocam stone wool selection starts with the application area before the product name.
