Professional Ductwork Insulation in the GTA
Konstruction Group provides professional duct insulation services for new construction and retrofit projects in Toronto. When HVAC ductwork runs through unconditioned spaces like attics and basements, proper insulation prevents energy loss and condensation problems. We install duct wrap insulation as part of our complete insulation services for custom homes and multiplexes, coordinating with framing and drywall for seamless project completion.
Why Insulate Ductwork
Uninsulated ducts running through unconditioned spaces can lose 25-40% of heating and cooling energy before the air reaches its destination. Duct insulation keeps conditioned air at temperature as it travels through attics, basements, and other unconditioned areas. It also prevents condensation on cold ducts in humid conditions, which can lead to water damage and mold. Proper duct wrapping completes the thermal envelope alongside wall and ceiling insulation.
Duct Insulation Services
- Duct Wrap Insulation – Fiberglass duct wrap with vapor barrier for exposed HVAC ductwork
- Supply & Return Ducts – Insulation for both supply and return air ductwork
- Attic Ductwork – Critical insulation for ducts running through unconditioned attic space

OBC Requirements
Ontario Building Code requires duct insulation when ductwork runs through unconditioned spaces. The required R-value depends on the application - typically R-8 to R-12 for ducts in unconditioned areas. We install insulation to meet code requirements for your project.

How much does duct insulation cost?
Duct insulation typically costs $3-$6 per linear foot of ductwork depending on duct size and accessibility. A typical home with 100-200 linear feet of ductwork in unconditioned space might run $500-$1,500 for complete duct wrap installation. We quote based on your specific ductwork layout.
What R-value is required for duct insulation?
Ontario Building Code typically requires R-8 to R-12 for ducts in unconditioned spaces. The exact requirement depends on the climate zone and application. Standard duct wrap products meet these requirements when properly installed.
Do all ducts need insulation?
Ducts running through conditioned (heated/cooled) space generally don't require insulation since there's minimal temperature difference. Insulation is most important for ducts in unconditioned spaces like attics, unfinished basements, garages, and crawlspaces where energy loss is significant.
Can you insulate existing ductwork?
Yes, we can add insulation to existing uninsulated ductwork as a retrofit. This is a common upgrade for older homes where ducts were installed without insulation. Access to the ductwork determines feasibility - exposed ducts in attics and basements are straightforward to insulate.
Does duct insulation help with noise?
Duct wrap provides some sound dampening, reducing noise from air movement and vibration. For significant noise issues, additional acoustic treatments may be needed. Standard duct insulation is primarily for thermal performance, with acoustic benefits as a secondary effect.
