EGGER

EGGER Boards and Structural Flooring

EGGER wood products available from MGN cover several different construction requirements. These EGGER boards are not interchangeable: the correct choice depends on whether the board is being used for a structural floor, a specified wall or ceiling construction, temporary construction exposure or a higher-load flooring application.

Do not select EGGER floor boards by thickness alone. Start with the required application and board classification, then check the structural specification, support arrangement, moisture conditions, temporary exposure requirements and installation method.

The quickest way to narrow down the EGGER boards UK range is:

• P5 structural flooring with a removable protective surface – Peel Clean Xtra
• P5 flooring requiring longer stated construction exposure – Protect
• Fire-retardant internal walls and ceilings – Flammex OSB3
• Heavy-duty structural flooring – HDX OSB4
• Board-joint and joist bonding – D4 Joint & Joist Adhesive

EGGER Chipboard Flooring: Peel Clean Xtra or Protect?

EGGER chipboard flooring is designed for load-bearing floor applications where the correct P5 structural grade, board thickness and installation system have been specified. Peel Clean Xtra and Protect both address construction-stage moisture exposure, but their protective surfaces and intended site benefits are different, so the choice should be based on the project rather than treating them as equivalent boards.

For Protected Floors and Clean Handover: Peel Clean Xtra

Peel Clean Xtra combines P5 structural chipboard flooring with a peel-away surface intended to protect the board during construction. The protective layer can be removed towards project completion, leaving the structural flooring surface underneath ready for the next stage of work.

Available options include:

• EGGER 18mm moisture resistant chipboard – the thinner Peel Clean Xtra flooring option currently available through MGN
• EGGER chipboard flooring 22mm – the thicker option for specifications requiring a 22mm P5 flooring board

Do not choose between 18mm and 22mm simply according to how wet the site may become. Board thickness should follow the floor design, joist or support arrangement and required structural performance.

For Longer Construction Exposure: EGGER Protect

EGGER P5 chipboard flooring from the Protect range uses hard-wearing, low-slip surfaces thermally bonded to both sides of the P5 core. When fully fitted using an approved EGGER method, the live MGN specification states protection for up to 100 days of weather exposure, making it relevant where the construction programme requires a longer stated exposure period.

Protect is designed for correctly specified internal structural floors, including humid internal conditions. The stated exposure performance does not make it a permanent exterior board or suitable for prolonged standing water, and the complete EGGER installation method must still be followed.

In practical terms:

• Choose Peel Clean Xtra where a removable construction-protection surface and clean handover are priorities.
• Choose Protect where the project requires the longer stated temporary weather-exposure period.
• Choose 18mm or 22mm only after checking the structural floor specification and support arrangement.

EGGER OSB Boards: Fire-Retardant or Heavy-Duty Flooring?

EGGER OSB in the MGN range covers two very different construction purposes. Flammex is structural OSB3 with a factory-applied fire-retardant coating for specified internal wall and ceiling systems, while HDX is OSB4 designed for demanding load-bearing flooring applications. Selecting between them should therefore begin with the required construction, not with board thickness.

For Fire-Retardant Walls and Ceilings: Flammex OSB3

Flammex uses a structural OSB3 core with a factory-applied intumescent coating. The live MGN specification identifies the range for mechanically fixed internal wall and ceiling applications, and the coated face must be installed and protected according to the specified construction.

Available Flammex options include:

• EGGER OSB 12mm fire retardant board – structural OSB3 for specified wall and ceiling systems
• EGGER 18mm OSB board – the thicker Flammex option within the live MGN range

The 12mm board must not be installed horizontally as flooring. Its coated surface also needs protection from direct weathering and liquid water, and MGN states that paint, wallpaper, laminate and other unapproved coverings should not be applied to the fire-performing face.

Fire performance depends on the specified board and construction being installed correctly. Do not substitute a standard OSB board simply because it has the same thickness.

For Heavy-Duty Structural Flooring: HDX OSB4

EGGER 30mm tongue and groove flooring is an OSB4 panel intended for demanding load-bearing floors. It is a different specification from Flammex because its primary role is structural flooring performance rather than providing the fire-retardant coated face used in the OSB3 range.

HDX should be selected where the floor design specifically requires a heavy-duty OSB4 tongue-and-groove panel. Floor loading, support centres and fixing requirements should be confirmed from the structural specification rather than assuming that a 30mm panel is automatically suitable for every high-load floor.

In practical terms:

• Choose Flammex OSB3 for specified fire-retardant internal wall or ceiling constructions.
• Choose HDX OSB4 for demanding structural flooring where that board grade is specified.
• Do not use Flammex as a substitute flooring board or HDX as a substitute for a specified fire-retardant system.

EGGER Joint & Joist Adhesive for Structural Flooring

Structural flooring performance depends on the installation system as well as the board itself. EGGER chipboard flooring adhesive is the compatible D4 Joint & Joist Adhesive available within the live EGGER range for structural flooring installation.

Its intended uses within the flooring system include:

• bonding tongue-and-groove board joints;
• bonding compatible flooring boards to joists where specified;
• helping seal exposed board edges as part of the approved fitting method.

Use the adhesive as part of the specified EGGER flooring installation rather than treating it as a general-purpose replacement for any construction adhesive. Follow the current application and safety instructions, particularly because structural floor performance depends on the complete fixing arrangement rather than adhesive alone.

Before Ordering Your EGGER Boards

Confirm the following before choosing a board type or thickness:

• Is the board being used for a floor, wall or ceiling?
• Does the specification require P5 chipboard, OSB3 or OSB4?
• Is temporary construction exposure expected?
• Does the project require a peel-away protective surface or a longer stated weather-exposure period?
• Is improved reaction-to-fire performance required within a specified construction?
• What board thickness is required by the structural design?
• What are the joist or support centres?
• Is a tongue-and-groove flooring edge required?
• Does the installation require the matching joint and joist adhesive?
• Will the board be exposed to direct weather or standing water beyond its stated limits?
• Are there restrictions on coatings or finishes applied to the board?

A board being described as moisture resistant does not make it waterproof or suitable for unrestricted exterior exposure. Likewise, a fire-retardant board should be selected and installed as part of the required construction rather than on the basis of thickness or appearance alone.

For structural floors, confirm loading, supports and fixing requirements before ordering. For walls and ceilings requiring fire performance, check the complete system specification, board orientation and permitted surface treatment before installation.
