Next Level Structural Efficiency

Investigating then modeling/planning is key to a good outcome. This is a before and after thermal image of an existing attic that was recently "topped up" to overcome some problems found with a thermal scan.

A summary of the change:
Original: ~R25, 6 hr phase shift of insulation layer.
New: ~R51, 12 hr phase shift, no more problematic thermal areas.
(The insulation thickness was NOT just doubled)

This R51 was limited structurally by the existing design of the roof/trusses and existing insulation already there. I would've like to see it a bit higher, but this is the best outcome for this house.

This change will reduce heat loss through the ceiling by ~50% (and also reduce summer cooling needs significantly). The longer phase shift will mean heat won't have a chance to impact the interior much before temperatures start to cool off at night. The insulation used will reduce sound issues as well as supporting a comfortable interior temperature year-round.

Weathershield cellulose was used (recycled paper) and they are also a sponsor for Passive House Alberta. Was great to support their product that is also made in Alberta!

A successful outcome starts with in-depth exploration which leads to strategic upgrades that matter.

If you fail to plan, you plan to fail. Investigate, plan, execute.
