Mounting Tape and Double-Sided 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.
N-Flex is a self-adhesive rubber tape against condensation on cold pipes and metal; Duo-Band is a double-sided acrylic tape for membranes and vapour barriers; M-Band is an acrylic tape with fleece facing that can be plastered over.

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.
