Can Tyvek Enercor be used as a house wrap?

I've ended up with Tyvek Enecor instead of Tyvek Housewrap. I'm wrapping OSB on my shed before installing battens and cladding.

The product says "Flexible sheets for water proofing - Underlays for walls".

You need to review the manufacturers guidance documents.

For a shed, I doubt it matters and it will do.

Essentially it's a breathable membrane so probably fine.

"Flexible sheets for water proofing" means breathable?

I have read on some sellers websites it's "vapour permeable".

I can't find the product on the Dupont website. I think it's usually used as an underlay for roofing, and can be used for walls. The data sheet I saw is from 2010/12

Tyvek Enercor Water Vapour Transmission (SD)
Nominal - 0,025
Min - 0,01
Max - 0,04

Tyvek Housewrap Water Vapour Transmission (SD)
Nominal - 0,01
Min - 0,003
Max - 0,025

As Enercor has a higher SD, it lets less water vapour through, I think

I would be happy to point out garden timber sheds and other timber frames built without wrap that are older than anyone and everyone who posts in this thread!

I interpret the data that actually the Enercor is (slightly) more water permeable than the Houswrap. But don't profess to really understand the figures and one will have been tested on a slope and one vertical so not really comparing apples with apples.

Anyway it won't make any difference to your shed.
