It had been blocked intentionally, but then when I did a better job of sealing barrier between the living space and the attic space, and restoring the airflow from under the eaves out through the attic ventilation it solved a lot of humidity problems I'd been having in the floor of the house, and along the walls on the ground floor , and the air felt warmer, and less stuffy in the living areas over all.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'> My house is a different vintage, but I think that the house was originally designed for natural draft ventilation has a lot to do with it. <o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'>Erin <o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> greenbuilding-bounces@lists.bioenergylists.org [mailto:greenbuilding-bounces@lists.bioenergylists.org] <b>On Behalf Of </b>Sacie Lambertson<br><b>Sent:</b> Thursday, November 10, 2011 6:14 PM<br><b>To:</b> Greenbuilding<br><b>Cc:</b> Dan<br><b>Subject:</b> [Greenbuilding] attic insulation in Seattle house<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Tahoma","sans-serif"'>All, I would appreciate advice. I am going to Seattle to help our son install insulation in an unconditioned attic in a 1906 house that has been completely upgraded with insulation everywhere except the attic. (As an aside, I was amazed to find in Seattle NO pre-50s houses on the market had attic insulation and most had none in the walls either--pretty amazing).<br><br>We plan to carefully seal any openings between the conditioned space below and the attic, then blow in however much cellulose we need.<br><br>J. Listiburek is quite adamant about the need for a wash of air via continuous soffit ventilation when insulating this way. But no one in the Seattle marine climate has continuous soffits vents. What is our alternative? What else should we be concerned about? Ice dams btw are not a problem in Seattle.<br><br>L. doesn't like one to store anything in the attic either, but if one has walk-in space up there, why not? What are the considerations here?<br><br>Thanks, Sacie</span><o:p></o:p></p></div></body></html>
