MS Polymer in the construction sector’s focus on embodied carbon and indoor environmental quality has accelerated scrutiny of every material in a building’s specification including sealants. For Green Star and LEED v4.1 projects, VOC content in sealants is a direct compliance parameter. For sustainability officers and green building consultants, it is also increasingly a procurement and reporting obligation that extends beyond certification into ESG reporting frameworks and client sustainability commitments.
Understanding VOCs in Sealants and Why They Matter
Volatile Organic Compounds (VOCs) evaporate at room temperature and contribute to indoor air pollution. In some formulations, they also contribute to atmospheric ozone formation. Traditional solvent based sealants and many polyurethane products carry significant VOC loadings released during application and the cure period, with residual off gassing continuing for weeks after installation. In well sealed, energy efficient buildings precisely the typology targeted by Green Star and LEED certification these compounds accumulate in indoor air at concentrations that affect occupant health and wellbeing. The outcome is a high performance green building undermined by its own sealant specification. Sustainability teams are increasingly motivated to close that gap.

LEED v4.1 and Green Star: Sealant VOC Requirements
Under LEED v4.1’s Indoor Environmental Quality Low Emitting Materials credit, architectural sealants applied inside the building must meet defined VOC content limits. The limits vary by product category, but the direction is consistent: lower VOC content contributes directly to credit achievement. Green Star projects similarly reward materials with lower environmental impact, including VOC performance, under the Materials credit category. For sustainability officers managing submissions, product documentation is essential. Simflex Facade’s safety data sheet and technical data sheet provide the VOC content data required for credit documentation available from Simseal on request.
Embodied Carbon: The Lifecycle Argument for Long Life Sealants
The embodied carbon conversation in construction has historically focused on structural materials concrete, steel, and insulation. Sealants represent a small fraction of total embodied carbon per project, but their lifecycle matters. A sealant requiring replacement every eight years contributes three times the embodied carbon over a 24 year building lifecycle compared to one that performs for the full period without replacement. Simflex Facade’s superior UV stability and movement accommodation directly support the lifecycle argument. Fewer replacements mean lower cumulative embodied carbon from the sealant system across the building’s entire service life.

Seal’em Solutions: Supporting Sustainable Construction Outcomes
Seal’em Solutions works with green building consultants and sustainability officers on Green Star and LEED projects across Australia. We provide product documentation for compliance submissions, apply low VOC products in line with certification requirements, and advise on sealant specifications that balance performance with sustainability objectives at the design stage, not after construction begins.
