Sandwich panels are a quick way to build roofs and walls, but their effectiveness depends largely on proper installation. The key element? Screws. Incorrectly selected screws can lead to leaks and damage. How to choose them?
Types of screws for sandwich panels:
- For metal (ZW6, ZW12) – used when the structure is made of steel.
- For wood, concrete, brick – ideal for traditional or mixed construction.
- With sealing washer – protect against water penetration.
- For fibre cement (e.g. Eurofala) – special threads and tips.
What should you pay attention to?
- Length – should take into account the thickness of the slab and the required anchoring depth.
- Tip – self-drilling, with a cutter or conical – depending on the substrate material.
- Protective coating – galvanised or hot-dip galvanised for corrosion resistance.
- EPDM seal – guarantees tightness and protection against leaks.
Installation errors:
- Over-tightening – may damage the board coating.
- Screws that are too short – lack of stable fastening.
- No washers – risk of leaks.
Examples of screws in our range:
- Screws for PIR wood/concrete boards
- Screws for steel structures ZW12
- Self-drilling screws with EPDM washers
Summary
Choosing the right screws guarantees the durability and tightness of the structure. If you have any doubts, please contact us and we will select the best solution for your project.
