Vapour Control Layer: Engineered for Condensation Control

AirGuard® air and vapour control layers (AVCLs) are 100% airtight. This helps to reduce convective heat loss and provide effective condensation control for all building types.

An AirGuard® vapour control layer can significantly reduce heat loss and increase energy efficiency. By controlling heat transfer and reflecting heat inside the building, they help keep buildings cool in summer, and warm in winter.

AirGuard® AVCLs offer highly engineered vapour control, to help your project meet sustainable building requirements and achieve environmental goals.

Using AirGuard® AVCLs for internal walls and insulating external walls with Tyvek® breather membranes creates a building envelope that is airtight and vapour-open. Together, they provide a holistic solution for optimum energy efficiency and interior comfort.

And because they are from DuPont, AirGuard® vapour control layers give you guaranteed quality, backed by a 25-year warranty.
