Installation Procedure for MARMOX Thermal Insulation System
(For Car Park Ceiling)
Method Statement
Introduction:
The following guide contains instructions that are essential to good thermal insulation system practice. Failure to adhere to these instructions could lead to problems with installation or untimely system failure. Follow the instructions of these TDS for all products used in Marmox Thermal Insulation System.
General Requirements:
- For appropriate system design, AIC (AMNA Insulations & Chemicals), Bahrain should be advised with all project details, site conditions and special requirements (if any) during the early stages of negotiations.
- A pre-installation survey of the property shall be carried out and recorded to confirm suitability of substrate for application of MARMOX Thermal Insulation System including modifications/repairs needed.
- Installation schedule of MARMOX Thermal Insulation System must be coordinated with other trades on the project and signed by the main contractor.
- The consultant and the main contractor prior to commencing with the installation must approve installation procedure and different sections details.
- Adjacent construction materials and/or fixtures that are likely to be soiled by the installation process must be appropriately protected.
- Scaffolding and other necessary equipment must be in place prior to installation.
- The main contractor should facilitate access to electrical power and clean water.
- All MARMOX Thermal Insulation System material should be protected from weather and other damages using proper storage and application.
- Insulation material should be stored on a firm, clean, dry and level base, which is off the ground. The insulation material should be protected from exposure to direct sunlight by storing open packs under cover in dry condition or by covering with polythene sheets.
- If any material is not mentioned in this guide and is to be used within the insulation system, a written approval must be granted by AIC, Bahrain to ensure the compatibility of this material to the MARMOX Thermal Insulation System.
System Components
The Marmox Thermal Insulation System consists of a range of different components applied in a specific sequence.
A typical MARMOX Thermal Insulation System consists of the following components:
Marmox Boards: An insulation material (Extruded Polystyrene rigid foam including a halogenated fire retardant, reinforced by polymer – cement – fiberglass composite), which is secured to the ceiling surface.
Mechanical Fasteners: Also, known as dowels, to fasten the Marmox board to the ceiling surface.
Joint Accessories: Self-adhesive fiberglass mesh tape and flexible joint compound are used to treat the joints between two boards.
Application and Installation Procedure:
1.1 Substrate Preparation:
The substrate for MARMOX Thermal Insulation System should have the following requirements:
- Remove projecting mortar burrs and fill render/plaster cavities to have smooth unified level.
- Concrete/render/plaster should be allowed to cure properly. New surface should be at least 4 weeks old prior to installation.
1.2 Marmox Board Fixing
- Install boards, staggering the boards and overlapping substrate Ensure the entire surface of the Marmox boards is level prior to the application of the next step.
- Fix Dowels on Marmox boards by drilling, to ensure that 40mm of the dowel is inside the wall substrate, with average of 3 – 5 dowels per square meter.
- Apply self-adhesive fiberglass mesh tape over the joints of Marmox Boards.
- Apply a thin layer of Joint compound on the top of mesh and dowels.
