Abet Laminati High Pressure Laminate MEG
MEG is a self-supporting high pressure laminate (HPL) with a decorative surface that is suitable for exteriors. It is fade resistant and weather-proof and complies with standard EN 438:2005 Part 6.
It is entirely made up of layers of phenolic resin-impregnated cellulose fibres with one or more decorative surface layers of cellulose fibres impregnated with thermosetting resins.
The manufacturing process involves the combined application of heat (150 °C) and high pressure (9 MPa) in multi-daylight presses in which resin polycondensation takes place. One or both sides can be decorative. It can be supplied as standard (MEG) or flame retardant (MEG F1) versions, the latter has flame retardant additives mixed with the phenolic resins.

Compact, self-supporting high pressure laminate (HPL) for exteriors, Abet Laminati MEG, made up of layers of cellulose fibres impregnated with thermosetting phenolic resins with one or two surface layers of decorative paper impregnated with thermosetting resins bonded together by high pressure with special protection against inclement weather in compliance with standards EN 438:2005 – Part 6.
The Advantages of MEG
MEG is a durable material, available in a wide range of colours. Its excellent technical properties make it particularly suitable for the building industry where it offers an ideal alternative to traditional materials.
MEG is used to clad façades and balconies, for street furniture and external signs, and is particularly suited for the creation of ventilated façades.
Physical and Mechanical Properties
Ageing performance and weather resistance
MEG can be exposed to the combined action of sunlight and atmospheric agents such as rain, hail, wind and salt deposits. These phenomena do not affect the decorative surface or the core.
Exhaust fumes and acid rain have no significant effect on MEG. The decorative layer is not subject to flaking or delamination.
Natural variations in temperature and humidity have no adverse effect on MEG’s properties. MEG is not affected by thermal shock and maintains its physical and mechanical properties. Extreme climate changes such as from –30 °C to +70 °C or from a dry climate to 90% relative humidity do not affect the appearance or the properties of the panel.
MEG undergoes a moderate dimensional variation due to the effects of natural phenomena: it contracts in low humidity and expands in high humidity environments.
For this reason the material should be conditioned at the installation site. If this is not possible or when the climate is characterised by significant temperature and humidity variations, special measures are required during the design and assembly stages, to be discussed with the local Abet Laminati representative.
The compactness of MEG provides an excellent combination of mechanical properties such as flexural, tensile, compressive and impact strength. The homogeneity and high density of the panels ensure maximum retention of fasteners such as screws or inserts.
MEG is not hazardous to health and does not pollute the environment. It is made up of 70% cellulose fibres and 30% thermosetting resins and does not contain asbestos or heavy metals.
MEG does not emit gases, fumes, solvents or liquid substances.
A very high percentage of raw materials used in the manufacture of MEG are renewable, following stringent environmental principles and criteria.
Industrial waste and any end-of-life residues can be stored and disposed of in the same way as urban waste products in controlled waste disposal sites in accordance with national and/or local legislation.
Its high calorific value makes MEG ideal for use in thermal recovery plants.
MEG has also obtained a positive Life Cycle Assessment (LCA), based on the ISO 14000 series of standards, the purpose of which is to establish a product’s environmental impact, taking into consideration the materials used, energy consumed and emissions generated during all phases of the product’s life, from the manufacturing process to disposal.
MEG surfaces do not require any specific cleaning procedure.
Any residue from machining or assembly operations can be removed with common, non-abrasive, household detergents using paper towels, sponges or soft cloths.
Rinsing is recommended to remove all traces of detergent and it should be dried thoroughly to avoid leaving marks. Normal grime deposits can be removed from the installed panels with common, non-abrasive, household detergents. Always avoid excessive rubbing or wiping and the use of instruments that could cause abrasion or scratching.
Eliminating Graffiti From MEG
MEG’s chemical resistant composition and closed structure prevent spray paints, various inks, emulsion paints, lipstick and crayons from sticking to the surface and penetrating the material. No preventive anti-graffiti treatment is necessary.
If the surface of MEG should be defaced by graffiti, and for any special cleaning requirements, please contact the local Abet Laminati representative.
In some countries it is compulsory, or may be considered beneficial, to have certification for the façade panelling application system.
The chart outlines the main certifications awarded to MEG.
In compliance with Directive 89/106/CEE “Construction Products” (CPD), the Notified Body LAPI certifies that MEG F1 conforms to the requirements laid down in Annex ZA of the product standard EN 438-7:2005. This certification authorises Abet Laminati to affix the CE marking on the whole range of MEG F1 products (ref. certificates no. 0987-cpd-037, 0987-cpd-046, 0987-cpd-067). Furthermore, the same Notified Laboratory LAPI, on the basis of the initial type and production controls tests, authorises Abet Laminati to affix the CE marking on MEG in the non-fire retardant version.
