When building a cathedral ceiling as a room
renovation project or as the ceiling for an entire
new home or cottage, it makes sense to start with
the best solution possible if starting from scratch.
This makes sense in colder climate zones since
a cathedral ceiling, by its very design, lacks the
optimum thermal performance when compared
to a vented attic.
Regardless, in warmer climate zones, and from an
aesthetic design perspective, many architects and
homeowners opt for modern cathedral ceilings,
and ROXUL COMFORTBATT
® insulation can play
an effective role in the Better I Best solution.
To increase the R-value of the cathedral ceiling, either
start with 2 x 12 ceiling joists, or add a 2" furring strip
to existing 2 x 10 joists, which gives a deeper
joist cavity to add the COMFORTBATT
® insulation.
Ceiling air space
When building a cathedral ceiling, the most
important reminder is to properly maintain an air
space of 25 mm (1") between the insulation and
the sheeting. Check your local building code for
specific recommendations.

Zero Net Energy (ZNE) Residential Buildings
The critical steps to reduce a building’s energy consumption usually
occur during the design process. The development towards modern zero
net energy (ZNE) buildings that take as little off the grid as possible, has
become possible through sustainable products like ROXUL
® stone wool
insulation. All ROXUL products produced in the Milton facility contain
a minimum of 40% recycled content.
