Easy to use and works well.
I applied it between my skirting board and floorboards. It adhered easily and has expanded to fill the gap really effectively and stopped the considerable draught. The slow expansion gives plenty of time to get it into small gaps.

AWESOME
AWESOME FOR FILLING GAPS AROUND FRAMES

Filled the gap nicely
We have a sizeable gap at the bottom of our Motorhome door and this expanded very quickly to fill it. As I’ve only used a foot or so there’s plenty left should we need to replace it. Very easy to apply as sticky tape.

brilliant product
Gives a draught proof seal for a variable gap between brickwork and window/door frame, and lasts for years.

Window seals
Easy tape to use, the expansion is slower in the colder weather which gives you a chance to stick around the windows and fit them without it catching on the ingos. Top tip in the summer is put it in the fridge to give you more time

Compriband 20/4
Never quite expands as thick as it say - always buy one bigger.

Idéal pour des joints entre parties fixes. Pas adapté pour des parties mobiles à mon avis, car je ne suis pas sur que la mousse supporte bien les efforts répétés. Attention: la mousse s'expanse très vite. Donc difficile à insérer dans un interstice si c'est votre besoin. Sur ma photo, on voit un châssis de porte installé sur une cloison désolidarisée du pignon, à gauche. D'où l'utilisation de ce joint souple pour faire la jonction. La partie bois OSB en retour (tranche visible) a été installée après mise en place du joint. Je ne pense pas que j'aurais réussi à installer proprement le joint si je l'avais fait en tout dernier.

Ni hecho a medida, ajusta perfectamente en la puerta de acceso a la terraza. Instalación inmediata y muy facil.

Dieses Komprimierband erfüllt seinen Zweck bestens! Es lässt sich leicht verarbeiten und passt sich gut an. Die anthrazitfarbene Optik ist unauffällig und passt sich verschiedenen Materialien gut an. Die Qualität macht einen soliden Eindruck, und es hält, was es verspricht. Eine gute Wahl für alle, die ein zuverlässiges Dichtband suchen!

Questo nastro è veramente buono. Non ero riuscita a levare tutta la colla del vecchio nastro di cattiva qualità, ma questo nastro non si spaventa di residui altrui! Si incolla che è una bellezza. Piano piano si espande e dona veramente un ottimo isolamento. Ora spero che regga anche anni e che non diventi uno "sbriciolame" come il vecchio nastro. Ma questo ovviamente potrò sapere solo tra qualche anno.

The seal tape glows as it advertises. But the glue is not strong.
