The government is focusing on increasing energy efficiency for both new and existing buildings to help meet Canada’s commitments to reducing carbon emissions in the next decade and beyond. The steps towards adopting “net-zero energy ready” building codes for new construction in Canada by 2030 are well underway and strategies to retrofit existing buildings are emerging. New policies are not only striving to maximize energy efficiency gains but are also introducing new measures to ensure that overall carbon emission targets for the construction, operation and renewal of buildings are met. The drive to reduce overall carbon emissions is creating the motivation for the building industry to challenge the prevailing approaches to the design and construction of the building envelope and look for opportunities to optimize assemblies for costs and performance. This webinar explores the synergies and opportunities of combining polyisocyanurate and mineral wool insulation with a structurally and thermally efficient cladding attachment system to achieve high thermal performance, reduce material use, decrease costs, and optimize wall thickness.
