HANNOBAND 3E The new foolproof one-component solution for sealing windows: weather seal, vapour membrane and insulation all in one.


  • All 3 window sealing functions in one
  • Easy, foolproof application
  • No internal or external foil required
  • No messy canister foam required
  • Meets the RAL guidelines for window fitting
  • Resistance to driving rain >1050 Pa


  • In very warm weather the foam will expand more quickly giving less time for location of the window in the frame. If possible, keep the product cool.

Hannoband 3E is quick and easy to apply. It virtually guarantees correctly sealed windows that will pass all modern building specifications and continue to perform year after year. What’s more, it comes with the added benefit of providing additional insulation, unlike silicone gel which is traditionally used to fit windows. With window technology improving year on year to prevent heat loss and consequently keep energy bills down, Hannoband 3E ensures those gains don't go to waste on fitting.






Frequently Asked Questions

What are your standard roll widths?

We slit most of our products to order, so we have no standard roll width. If you want 13mm or 133mm, you can have it.

What is the minimum and maximum roll width?

As a standard, the minimum is 6mm. We can slit most products narrower than this (we have slit down to 1.6mm) but we charge the same per roll as if it were 6mm, due to the increased slitting and packaging difficulty and the increased waste. The maximum width depends on the product, but is usually at least 1 metre.

Are the products held in stock?

We hold large quantities of bulk rolls in stock and manufacture to order. That's the only way we can offer the number of products and product variations that we do.

What is your delivery time?

UK deliveries on rolls, 3 to 5 working days. Spools, pads and die-cuts are 10 working days. If your order is urgent, please speak to our sales department and we'll try to help. Export orders are subject to longer delivery times.

How much do I have to order?

Our MOQ on most rolls is £100. On rolls of Techniflex and on other formats it is £200.

What are the delivery charges?

On UK orders over £200 delivery is free. On orders between £100 and £200 we add a small order charge of £20. We can arrange a.m. and courier deliveries for additional charges.

What is your returns policy?

As our products are made to order, we cannot generally accept returns unless the goods are faulty. 

What guarantees do you offer?

We are proud to guarantee the quality and performance of all our products and will quickly provide a replacement or refund if they fail to meet our standards.

Do you export, if so where?

Yes, we export around the world. Currently we export to Europe, the Far East, Australia and the US.
