Your plan to utilize two-inch-thick EPS as your air flow baffle will function. The EPS is to some degree vapor-permeable, so it will allow a little little bit of outward drying. (In almost any case, when you Create a fairly airtight ceiling, there will not be any dampness With this assembly that needs to escape.)

As an example that a certain making follow ends in a 20% failure rate. That observe could be fully unacceptable to builders, who don't desire callbacks or problems. But that exercise would nevertheless result in eighty% of customers being content.

I'm a homeowner in Seattle. Have got a newly-framed, vented cathedral ceiling to insulate. Straight bays, 2x12, 24" o/c. The current plan is to employ batts of some variety during the bays, acquire care to air seal the inside surface, avoid penetrations, air seal the vent channel also (bays absolutely sealed), double primary the inside surface area for vapor resistance. I have a couple questions about baffling the vent channel: one. Many of the building specialists I am Operating with sense the jury is still out on baffles and are recommending leaving the batts open up to the channel other than near the vents, assuming the 1-two" air channel is often managed.

Many thanks for that affirmation and advice. Since all the things is dry this time of yr and the home was lately tented for termites, I'll insulate from the beam and seal up the apparent air entryways. When I can see inside I think I will have a greater strategy how much humidity has actually been in there over the years.

My opinion is that the steep facet of a mansard roof is a roof. This is very true if the exterior with the sloped assembly is finished with roofing.

Many thanks Martin - Now I see why my authentic plan for just a SIPS envelope was so elegantly easy. It seems like min R-ten sprayed underneath the roof sheathing and then a full-fill in the bays with batt / fluffy, along with a vapor sealed drywall lid can get me the 'very hot' (unvented) roof procedure the SIPS was from the get go.

If I have an understanding of properly, you've got just concluded putting in some recessed can lights, and now you want to know tips on how to insulate around and earlier mentioned these can lights. Your intention is to install a new finish ceiling, underneath the rafters, once the insulation is put in. Is that accurate?

I haven't got lots of space higher than or underneath the roof construction for insulation / venting. Would her comment is here a flash / batt unvented assembly get the job done below the single sheathing deck? My insulator has done Numerous of such locally.

Our cooler mornings could make the inside of my metal roof sheeting to sweat slightly given that It's going to be in touch with the hotter unvented fiberglass-insulated purlin "cavity" beneath. After our warm Caribbean sunshine starts to kick in I would like this dampness to dry and/or diffuse out of the cavity, with the gypsum sheeting, into the cathedral living Room underneath, to then be Visit Website blown outside of my 4x3 gable window. A vapor barrier would absolutely retard this method.

Therefore, we advise that just before Doing work with a company Specialist you validate that details offered remains to be existing and/or acceptable to you.

I would like to promote cost-efficient efficiency in my industry, although not with the price of roof failure. We're a 5B weather zone with 6000 HDD, heating from mid-Oct to mid-April. We may also be particularly dry at 7000 ft above sea stage.

I've created dense-packed unventilated roof assemblies various instances without dilemma. Obviously I have not torn into them either. I would want to see much more samples of failures in These types of assemblies whenever they're around.

Even though the GBA website currently incorporates lots of posts on The subject, we keep on to acquire Repeated questions about the best solution to insulate a cathedral ceiling.

I have created log houses during the Yukon Territory in northern Canada for 30 several years. Most log properties have cathedral ceilings. Many of the roofs We have now constructed are as follows (from the bottom up): published here log purloins, nominal two" (2x6) t&g decking, 6mil poly, 1 1/two" extruded polystyrene foam, 2x10 rafters on 24" centers, seven" fiberglass, 2x4 strapping, 7/sixteen OSB, underlayment (fifteen lb paper, 30lb felt, or now we might even use ice and drinking water shield). There can be about an inch of air Room below the strapping for each vertical and horizontal air movement. All roofs are vented with strip vents with the eaves and vents while in the soffit (2x6 t&g) at the height at the two finishes. I would disagree that venting will not be necessary when you cease the airflow on The nice and cozy aspect, for two factors. Very first it really is very difficult to prevent all airflow, Specially with conventional common tactics (ie chimney and plumbing vent penetrations throughout the roof) We now have several techniques developed over time to seal the vb within the eaves and gables, but there remain nail penetrations from the vb. Total I feel we had really tight seals but a person could in no way say airtight.
