System insulation board - with protective foil - 1400x800mm (1,12m2); black - 6,72m2/6pcs IVAR.COMBITOP ND 30 N

Product detailed description

This insulation board is used in underfloor heating and cooling systems to ensure even heat distribution and reduce thermal losses. It is commonly installed in residential and commercial buildings where hydronic radiant systems are employed. The board is designed to be laid in a grid pattern with specified spacing between the heating pipes. The protective foil ensures a smooth surface for screed or floor finish, while the insulation core minimises heat loss to the subfloor. The board is suitable for use with ALPEX or PEX pipes and is intended for installation by qualified professionals who understand the requirements of hydronic systems and building regulations.

Proper installation requires careful planning to ensure the system operates efficiently. The board is cut to fit the room dimensions and arranged with the correct spacing between the pipes. It is essential to follow the manufacturer's guidelines for spacing and pipe routing to avoid thermal bridging or uneven heat distribution. The board is typically installed before the screed is applied and must be handled with care to avoid damage to the protective foil.

Technical parameters

Installation and connection

Installation begins with the preparation of the subfloor to ensure it is clean, dry and level. The boards are then laid in a grid pattern, with the protective foil facing upwards. The spacing between the pipes is determined based on the system design and the desired heat output. It is important to avoid overlapping the boards and to ensure they are tightly butted together to prevent gaps. The board should be cut using a fine-toothed saw or utility knife if adjustments are needed for irregular room shapes or obstacles.

Common installation mistakes include incorrect spacing, which can lead to uneven heat distribution, and failure to protect the board from mechanical damage during screed application. Installers should also ensure that the board is not exposed to direct sunlight or high temperatures before the system is operational, as this can affect the integrity of the protective foil. After installation, the system should be pressure tested to check for leaks before the screed is applied.

Compatibility and accessories

This insulation board is specifically designed for use with underfloor heating systems that use ALPEX or PEX pipes. It is compatible with standard pipe diameters of 16, 17 and 18 mm. To complete the installation, additional components such as manifolds, pipe fittings, and thermal sensors may be required. These components should be selected based on the system design and the manufacturer's recommendations. It is important to ensure that all components are compatible with the selected pipe type and system pressure requirements.

Technical background for designers

The board functions as a thermal insulator, reducing heat loss to the subfloor and ensuring that the majority of the heat is directed upwards into the room. The insulation material is typically a rigid foam with high thermal resistance, and the protective foil serves as a barrier to prevent the screed from bonding directly to the insulation. The board is designed to be integrated into the overall system layout, with the spacing between the pipes determined by the heat load and room dimensions. The choice of pipe diameter and spacing affects the system's efficiency and response time. A higher thermal resistance in the insulation material can reduce the required pipe spacing and improve system performance.

The long-term efficiency of the system depends on the correct installation of the board and the use of compatible components. The board must be installed in a dry environment to prevent degradation of the insulation material. The protective foil should remain intact to ensure a smooth surface for the screed and to prevent the insulation from being exposed to moisture or mechanical damage.

Service and operation

Once the system is operational, the board requires no active maintenance. However, it is important to monitor the system for any signs of leaks or inefficiencies, such as cold spots or uneven heat distribution. If the protective foil is damaged during installation, it should be repaired or replaced before the screed is applied to prevent long-term issues. The system should be pressure tested periodically to ensure there are no leaks in the piping or connections. No specific service intervals are required for the board itself, but regular system checks are recommended to maintain optimal performance.

Frequently asked questions

Can the IVAR ND30N board be used with PEX pipes?
Yes, the board is specifically designed for use with PEX pipes with an outer diameter of 16, 17 or 18 mm. The protective foil ensures a smooth surface for the screed and prevents direct contact between the pipe and the insulation.

What is the maximum pipe spacing allowed with this board?
The board supports pipe spacing from 50 to 300 mm. The exact spacing should be determined based on the system design and the desired heat output for the room.

Can the board be cut to fit irregular room shapes?
Yes, the board can be cut using a fine-toothed saw or utility knife. It is important to ensure that the cut edges are clean and that the protective foil remains intact after cutting.

Is the board suitable for use with underfloor cooling systems?
Yes, the board is suitable for use in both underfloor heating and cooling systems. The insulation and protective foil help maintain system efficiency and prevent thermal losses.
