Posted By: Viking HouseHi Peter, Just screw into the latt through the EPS and into the rafter below, the second latt is screwed into the 1st latt through the top layer of EPS.On a seperate note! I got an enquiry last week from somebody wanting to build a Passive House in Budapest, do you build houses?
Posted By: spoonandfork So with your first layer of EPS all your battens line up directly with the rafters below? And your picture above shows the first layer ready for the next layer (which will have perpendicular battens)?
Posted By: Viking HouseThat's the way we did it.
Posted By: Viking HouseYes, you're correct Spoon, I misread your question, here's the detail we used.http:///forum114/extensions/InlineImages/image.php?AttachmentID=2017" alt="Ext Ins TF Roof.jpg" >
Posted By: Viking HouseThis is our flat roof solution! The roof is airtightened from the outside using silicone between the rafter and the Ply.
Posted By: Mike GeorgeA warm roof is simply a roof with ALL of the insulation outboard of the STRUCTURAL element. [In your case, the rafters]. There can be many variations to Timber's example above, including the inclusion or omission of vapour control layers/barriers and breather membranes. The choosing of these dependent upon the other materials physical properties. Not least their vapour permeability.
Posted By: borpinSo what do you call a roof with some insulation outboard of the rafters and sarking and some inside the rafters sarking?
Posted By: borpinpage 5 of the PDF shows 18mm sarking but would this work with OSB?
Posted By: davidfreeboroughThis looks like the standard Scottish way of laying slates where the norm is to leave 3mm gaps between square edge sarking boards. Large sheet sarking materials are normally specifically excluded from the BBA certificates of breathable membranes which allow this approach.
Posted By: pmagowanWhat about squirty foaming them together?
Posted By: borpinAny reason for this exclusion? Breathability of the Wood? How good could you make the outer insulation layer air tight? Perhaps glue the 2 layers of insulation together or glue the outer layer to the rafters and glue or tape the joints? I'm sure it would end up pretty air tight.
