<div>Dear all,</div>
<div> </div>
<div>As a new user of ESP-r, I'm having difficulties when defining new materials and constructions. </div>
<div>I have added new constructions for a window and a glass facade, both divided in an outer glass sheet, a cavity with an Argon filling, and another glass sheet.</div>
<div>Now I get the message: "Air gap resistance too small in zone X, surface Y, gap Z, please increase!"</div>
<div>When looking back at my zone definitions, the indicated surfaces are all glass/window surfaces. I had the same problem with my outer wall definition, but changing the conductivity up, and finally back down to the desired value was enough to solve this.</div>
<div>I have tried the same for the window constructions, but it doesn't seem to help. What exactly is the problem, and how to solve it?</div>
<div> </div>
<div>Thank you in advance.<br clear="all"><br>Kind regards,</div>
