Step-by-Step Install of a High-Performance Cathedral Ceiling

When designing the roof assembly and cathedral ceilings for Model ReModel 2022's in-law suite addition, builders Nicole Tysvaer and Matt Kulp of Symbi Homes worked to prioritize energy efficiency, wellness, and beauty. 

"We needed a minimum R-49 roof, a ventilation system to prevent moisture problems, and increased ceiling height to create a sense of spaciousness in the main living area," says Symbi Homes CEO Nicole Tysvaer. 

Symbi chose sustainable, formaldehyde-free Greenfiber Sanctuary, a dense-packed cellulose insulation blown into the 18" cavity of their roof trusses (R-3.7 per inch), which exceeded their thermal protection goals, but also added considerable weight to the roof assembly. 

To prevent any future sagging of the material, Kulp added 3/4" battens across the cellulose netting and finished the ceiling with 1/2" birch plywood, which will be left exposed. 

"The clear-coated plywood ceiling is absolutely beautiful and gives the addition a cozy, modern cabin vibe," explains Tysvaer.
