Mounting Tape and Double-Sided Tape
When to use mounting tape
Mounting tapes replace screws, nails and liquid sealants where a fast, clean and durable bond is needed. A strong mounting tape holds the load immediately after application — no drying time and no props.
Waterproof mounting tape matters outdoors and in wet rooms: at vapour barrier and diffusion membrane joints, under decking, in bathrooms and on roof structures. Alenor acrylic and rubber tapes keep their bond strength through repeated freeze–thaw cycles.

Frequently Asked Questions
Which mounting tape is right for joining vapor barrier membranes?
For membrane overlaps, Alenor M-Band non-woven acrylic tape or Duo-Band double-sided acrylic tape both work well, giving an airtight and vapor-tight seam.
What is N-Flex synthetic rubber tape used for?
N-Flex is designed for insulating cold pipes and HVAC systems — it prevents condensation from forming on cold surfaces and also seals ventilation joints flexibly.
Are mounting tapes suitable for outdoor use?
It depends on the specific product — some are meant for indoor use only (e.g. under finishing materials), while others withstand UV exposure and rain. Check the product description before buying.
Do I need a primer before applying mounting tape?
On porous or dusty surfaces (concrete, brick) a primer is recommended to improve adhesion. On smooth, clean surfaces (metal, plastic) a primer usually isn't needed.
