Maintaining adequate ventilation in a “Cape Cod” home, a “Story and a Half” home, “A-Frame” home, or home with a vaulted ceiling requires some special approaches. See our pages on story-and-a-half homes for more information.
Vaulted ceilings and cathedral ceilings create grand interior spaces, but are often difficult to properly insulate and ventilate. Made up of enclosed rafters often no deeper than 6”, these types of ceilings offer little room for packing in insulation, which makes achieving the necessary R30+ for containing heat and eliminating ice damming in our Western Wisconsin and Twin Cities Metro area homes a real challenge.
Ideally, vaulted ceilings should be:
Air sealing for vaulted and cathedral ceilings is a relatively easy requirement, as long as the ceiling is drywalled. Our teamdoes simple sealing of penetrations like light boxes and recessed fixtures. If the ceiling is tongue-and-groove paneled, chances are more leakage will result. At a minimum, the perimeter of a paneled vault should be sealed with a silicone sealant.
In some cases, the rafters of a vaulted ceiling may be deep enough to accommodate sufficient insulation. Additional insulation can often be blown in over a vault from an adjacent attic space or from outside (typically through the ridge of the roof). If it’s time for a new roof anyway, now is the perfect opportunity to both air seal and insulate your vaulted attic by tearing off roof sheathing and spray foam insulating the space from above. Whatever the case, whatever the material, a minimum of R30 insulation needs to be applied in these spaces. Enough room should also be left for ventilation.
Keeping the roof decking cool limits the growth of ice dams in winter and blocks heat buildup in the summer. In order to keep the roof decking cool, a continuous ventilation channel should run from the eave to the peak in a vaulted attic. Often overlooked by builders and remodelers, ventilation can be opened up (in some cases) by inserting vent chutes from above, or from the exterior (like when retrofitting spray foam). Each rafter cavity should be able to “breathe” into a ventilated soffit space at the eave, and should terminate at the high side of the roof to a continuous ridge vent.
If your Western WI or Twin Cities area home has sloped ceilings and could use some extra attention, don’t wait to fix it. Call us today to schedule your air sealing, insulation, and ventilation appointments!

St . Croix County Historical Society is gratefully pleased with the service and advise provided by St Croix Energy Solutions . SCES performed a thorough energy audit of the Octagon House Museum and the caretaker's apartment free of charge. Their representative, Pete Morsch, willingly attended a meeting of the Board of Directors to explain his recommendations for the Museum complex. Pete made several visits to the Museum to fully examine the premises. The Society Board of Directors agreed to the installations recommended to the extent our budget would allow. SCES also advised SCCHS regarding available rebates toward the cost of the energy upgrades that were made.
