Multi foil Insulation
Is it possible to model multifoil insulation in WUFI Pro? It is difficult to obtain all the minimum parameters required, but before I ask for additional information I would like to know if it is possible to model anyway. Thanks for any help that can be offered.

Re: Multi foil Insulation
It depends what you mean with multifoil insulation?
If you mean foils on both side of the insulation, yes
If you mean 2 foils on one side, yes

Re: Multi foil Insulation
thank you for getting back to me, by multi foil I mean an insulation with foil on both sides of the insulation. The insulation is formed as a honeycomb structure with aluminium foil fixed to both sides. Could you explain how I would need to create this material in Wufi Pro 6 please.

Hi Colin,
can you please post a sketch or drawing of the material section?

Re: Multi foil Insulation
Hi Christian, I have tried to post an image of the material but it is too large for this portal, is there another way that I can get you the image of the materials in question ? may be e mail ?
Thanks
Colin
Thanks

Re: Multi foil Insulation
I have uploaded 3 images
1. the roof structure
2. a actis insulation material
3 the multifoil insulation
if you could let me know if this can be modelled and if so would i need to build each individual layer of the multifoil to accurately gauge performance.
Thank you for your help

Re: Multi foil Insulation
Hi Colin,
we do not have such a multilayer insulation in our database. You can generate you one by using the given lambda value and calculate the permeability to a µ-value. If there are metal foils on the surfaces, you can express them by using placing an additional vapor barrier (sd = 1500m) on that position.
