Our patented Multi-Purpose Weather Performance Sill can be installed surface mounted, partially recessed to accommodate varying inside and outside finish floor heights, and fully recessed into the floor for a clean uninterrupted transition from outside to inside. Our sill design provides an engineered water management system that allows any potential water collected by the still to weep out or run via drainage tubing. For partial and fully recessed sill installations, drainage fittings and tubing are included for water to drain to your desired location.
