Rerurn to Romy the Cat's Site

Scooter, many houses in the Northeast were roofed by people who understand how this works, and the first few courses of shingles are "underlain" accordingly, to preclude such seepage. In Romy's case, I believe he could simply treat the entire horn like a "room", since the conditioned air from the house will moderate the horn's temperature, etc. via the horn mouth, in any case. The floor/ceiling area under the horn would need special attention before the horn was installed, with high-value insulation going into the relatively shallow joist bays, before the horns were slid in.  Then, the horns themselves would need to be fully insulated, probably with foam, and the remainder of the "gable" wall from which the horn mouths emerge should also be fully insulated.  This would complete an insulated shell around the conditioned "space", and the attic, per se, could then be fully ventilated, as it is now.

I would like to keep this site dedicated to audio subject but unfortunately I moved astray. Investigating my insulation dilemma I did not know that I would step in the middle of a huge debate that is going on in industry. My dilemma is that I would like to have my horn insulated and to ask as a “house room” but top sides of the horns are the bottom sides of roof and applying insulation above the horn means to apply insulation under the roof.

I have research the contemporary high-tech insulation products – the open sell foals, like Icynene and alike. I can mix it with led or large sand and get my mass and isolation. The question is if it right thing to do. What I will be doing is creating what the industry call “compact roof” by applying the foam under the room preventing air to move through or around the bottom of the roof, creating a complete air barrier.

This becoming very fashionable practice of foam insulating the attic is raising eyebrows in the building industry because typical techniques call for attics to be ventilated. By insulation attic from room the room get much cooler on summer and much wormer during winter but it also raises the temperature of the roof’s shingles very dramatically and prevents the shingles to be warmed during the winter. The debts are going on between builders and between the people who sell foaming services. The first one hate it, the last one love it. It is not a big deal to buy a set of DIY-targeted TigerFoam or alike and to apply it to my horn’s outside but  I am still not convinced.

Hm, I am wondering …
