Hi,
How can I create the following:-
a) an external wall that is composed of glass blocks?
b) an external wall that is half brick and half glass blocks?

I don't think I can create a glass wall perse as the constructiuon Db separates glazing from opaque construction but I can fudge that by making a wall of tiles that I give some glass-like properties to (hopefully that'll work).
But to make hlaf the wall brick and the other glass blocks seems a bigger problem.

Any help would be much appreciated.

thanks
Norm

The best answer that I could get from IES when I asked how to create a wall out of two materials was to add doors to the wall in question in the places where you want a second material. Then change the properties of the doors you've added to (in your case) glass. make sure that there is no infiltration around the door, as although in effect you are creating a segment of wall, IES will view it as a door with gaps around the border. Then change the thickness/resistance values of the glass to achieve the same U-value of a glass block. Remember for an IES point of view the material name doesn't matter as long as the u-value is accurate (and density/thickness, for glass: emissivity, reflectance, transmittance etc).

I hope that helps.

Hi,
I messed around a bit and used windows instead of doors. Interesting that IES suggested doors to you ... I'll have to check butI expect there are more limitations in pretending that window is a glass wall than a door is.
