  4. Do you offer custom cutting of sandwich panels?

    Yes, LB THERM offers precise custom cutting of sandwich panels. Thanks to a modern cutting machine launched in 2023, each panel is cut with maximum accuracy – with smooth edges and perfect finishing. The service is available for almost all product groups, including HPL, PVC and GFK panels. Orders are processed according to individual customer dimensions.

  5. What is the lead time for sandwich panel orders?

    The standard lead time for sandwich panel orders at LB THERM is up to 5 working days. This applies to panels available in the standard offer. For non-standard orders or custom cutting, the lead time is determined individually. Efficient logistics and our own machinery park allow us to maintain short lead times even for larger orders.

  6. Do you provide transport of sandwich panels and who is responsible for delivery logistics?

    LB THERM delivers across Europe. The terms and costs of international transport are agreed individually – please contact us.

  7. Do you offer international delivery of sandwich panels?

    Yes, LB THERM delivers across Europe. The terms and costs of international transport are agreed individually – please contact us.

  8. What are sandwich panels used for?

    Sandwich panels are used in construction, industry and transport – including door infills, façades, vehicle bodies, machine enclosures and advertising systems.
    The range of applications depends on the type of facings (e.g. HPL, aluminium, PVC, GFK) and the core, allowing the panel to be tailored to specific technical requirements and operating conditions.

  9. Which sandwich panels are suitable as infill for external doors?

    For external door infills, ALUMINIUM, HPL and sandwich panels with an aluminium or compensating layer are the best choice. LB THERM panels are characterised by high resistance to abrasion, moisture and weather conditions, as well as colour stability in outdoor environments.

  10. Which sandwich panels should be selected for industrial and transport applications?

    For industrial and transport applications, glass fibre reinforced panels are the best choice. At LB THERM, there are several variants of sandwich panels with GFK facings: gloss, with visible reinforcing mesh, and standard matte finish.

  11. Are sandwich panels suitable for refrigeration and specialised structures?

    Yes, sandwich panels are widely used in refrigeration and specialised structures, such as refrigerated units, isothermal bodies and commercial vehicle bodies. The key factor is the proper selection of the core (e.g. XPS, PUR) and facings, which ensure thermal insulation, tightness and resistance to operating conditions. In LB THERM solutions, panels are designed depending on the application, allowing them to be tailored to the requirements of refrigerated transport and industry.

  12. Are sandwich panels resistant to UV radiation and weather conditions?

    Yes, sandwich panels can be resistant to UV radiation and weather conditions – however, the key factor is the type of facing used.
    The highest resistance to sunlight, moisture and temperature changes is provided by panels with HPL and ALUMINIUM facings, which is why they are recommended for outdoor applications. They ensure durability, stability and an aesthetic appearance even during long-term exposure to weather conditions.
    In the case of PVC-faced panels, UV resistance is lower, which is why this material is most often used indoors or in less demanding conditions.

  13. Which sandwich panel finishes are best for outdoor use – HPL, aluminium or PVC?

    For outdoor applications, sandwich panels with HPL and aluminium facings are the best choice. HPL provides high resistance to mechanical damage, UV radiation and colour stability, which is why it is often used in entrance doors and façades. Aluminium, on the other hand, offers high stiffness, corrosion resistance and the possibility of precise finishing in the RAL colour palette. PVC is a more economical and functional solution; however, it is used less frequently outdoors, mainly in less demanding conditions. PVC 7016 does not have UV protection and is not recommended for outdoor use.

  14. What applications are GFK panels best suited for?

    At LB THERM, GFK sandwich panels (glass fibre reinforced) are best suited for applications requiring high mechanical resistance, low weight and durability in demanding conditions. They are widely used in the transport industry (vehicle bodies, trailers, refrigerated units), as well as in industry, construction and structural elements. Thanks to their structure, GFK panels are resistant to moisture, corrosion and weather conditions.

  15. What are the advantages of GFK panels in transport and industry?

    GFK panels offer a range of benefits that are particularly important in transport and industry. First of all, they combine high mechanical strength with low weight, which improves structural efficiency. They are resistant to moisture, corrosion and weather conditions, which translates into durability in intensive use. Additionally, they withstand dynamic loads and vibrations well, which is crucial in vehicle bodies and industrial applications.

  16. What finishes and decorative options are available for sandwich panels?

    At LB THERM, we offer over 300 variants of decorative foils from renowned manufacturers. These include solid colours, wood-like structures and finishes aligned with current trends in the window, door and architectural industries.
    For sandwich panels with aluminium facings, powder coating is available according to the full RAL palette, allowing precise colour matching with window and door systems, façades and individual projects.
