Alexphd1 Posted November 14, 2016 Share Posted November 14, 2016 Whats the general thoughts on the where the waste pipes come through the DPM. Use a proper of the shelf DPM top hat or make your own top hat with DPM and tape? Link to comment Share on other sites More sharing options...
Dudda Posted November 14, 2016 Share Posted November 14, 2016 (edited) I just made my own. What I've seen recently and think is a good idea is to insulate the pipe where it passes through the slab. See image in bottom right. Ignore the others. image taken from: https://passivehouseplus.ie/magazine/new-build/west-cork-passive-house-raises-design-bar Edited November 14, 2016 by Dudda Link to comment Share on other sites More sharing options...
Gone West Posted November 15, 2016 Share Posted November 15, 2016 Our DPM is above the foundation insulation and was taped to all the penetrations through the DPM. The square block covered in DPM is the waste for the wetroom shower. Link to comment Share on other sites More sharing options...
