The Problem

  • The basement opening sat in exposed masonry and needed a durable separation point for regular service access.
  • A light-duty door would not suit the physical conditions or the identified fire-rated application.

How We Fixed It

  • DoorWin prepared the opening, installed the fire-rated steel frame and slab, aligned the hinge and latch sides and checked the completed door for dependable closing and access.

Rated Openings Need Coordinated Components

A fire-rated door is more than a steel slab. The door, frame, labels, hardware and closing behaviour all need to suit the opening and applicable project requirements.

Final Result

The Burlington basement corridor received a cleaner, stronger fire-rated steel opening for daily building use.
