LNE offers building and construction products professionals a complete range of services that meet all their industrial challenges: quality products to combine performance and sustainable development. We supports them from the design of products to their market launch, including reuse, a key activity in the circular economy.
Performance, innovation, competitiveness, compliance, quality
Whether you are a manufacturer, architect, builder, energy supplier or design office, the challenges you have to face involve:
- Compliance of products and materials with numerous regulatory requirements (CPR, RE2020, ERP, EUP, VOC, Energy Performance Directive, etc.),
- compliance with time-to-market deadlines,
- Control of costs and production processes.
You must also meet the challenges of ecological transition by ensuring that the carbon footprint of your products and buildings is reduced, by limiting the environmental impact by using reused materials for example.
Services offered
Thanks to its personalized technical support offer, LNE positions itself as your single point of contact, capable of taking charge of your project as a whole and helping you achieve your objectives.
LNE offers a wide range of test methods to assess the performance of your building products and systems. They are based either on standardised tests or on customised tests.
- Thermal properties: thermal conductivity and resistance, emissivity, infrared thermography, in-situ measurements, large-scale tests, etc.
- Mechanical properties tensile behaviour, compression behaviour, shear behaviour, bending strengh, fatigue test, shock test, compressive creep, geometry, dimensions and dimensional stability, settling, etc.
- Hygrometric properties: water vapour transmission properties, water absorption, moisture content, hygroscopic sorption properties,
- Physico-chemical properties: chemical composition, gas content, microscopic analyses, etc.
- Optical properties: measurement and technical expertise on the optical performance of your materials
- Acoustic properties: sound absorption
- Characterization of nanomaterials (in french only)
- Reaction to fire tests: French and European regulatory compliance tests (Euroclass, “Classement M”
- Environmental tests: climatic, EMC, electrical safety, vibrations, transport simulations
Regulatory and voluntary certifications
LNE supports you in your efforts to certify your construction products by issuing the CE marking and the ACERMI mark and the KEYMARK
- CE marking according to the Construction Products Regulation
- CE marking for thermal insulation (Acermi)
- KEYMARK
as well as many NF marks:
- NF Slates
- NF Fire Safety - PVC Tubes and Fittings - Coated Textile Supports
- NF Polyethylene Pipes
- NF Extruded products based on vinyl compositions for outdoor use
LNE also issues its own LNE Fire PS mark: Fire behaviour of thermal insulation materials (EPS raw materials and XPS)
LNE performs different types of numerical simulations:
- multi physics,
- WUFI,
- Static
- 1D/2D/3D,
- Fire safety engineering, smoke extraction.
- Technical assistance,
- help to innovate and improve your products,
- expertise and in situ diagnostics,
- drafting of testing protocols,
- assistance with the development of test benches or acquisition from test bench manufacturers
