{"title":"Fire Door Frames, Linings \u0026 Casings","description":"\u003ch2\u003eThe Frame That Makes a Fire Door a Fire Doorset\u003c\/h2\u003e\n\u003cp\u003eA fire door only earns its rating as part of a complete doorset, and the frame is where that begins. A fire door frame or lining is engineered to hold the door squarely, house the intumescent seals that swell to close the gaps as temperatures rise, and resist fire for as long as the door it carries, so the whole assembly performs the way it was tested to. Hang a fire door in an ordinary frame and you lose much of the protection you paid for.\u003c\/p\u003e\n\u003cp\u003eThese frames, linings and casings are made to suit standard fire door openings across both 30-minute and 60-minute ratings, in finishes chosen to match the doors they carry, from paint-ready white primed to real oak and walnut veneer. They're one part of the wider set of \u003ca href=\"https:\/\/internaldoors.co.uk\/pages\/fire-door-hardware\"\u003efire door hardware\u003c\/a\u003e that turns a door blank into a compliant, working installation.\u003c\/p\u003e\n\u003ch3\u003eWhat makes a fire-rated frame different\u003c\/h3\u003e\n\u003cp\u003eA fire-rated frame or lining is built from timber of the correct species and thickness to hold its shape and resist fire, with a groove that carries the intumescent seal around the door. That seal is what closes the smoke and flame path once a fire takes hold, which is why a standard lining can't stand in for a rated one. Some of our frames arrive with the seals already fitted; where they don't, you'll find the right ones among our \u003ca href=\"https:\/\/internaldoors.co.uk\/collections\/strips-and-seals\"\u003eintumescent strips and seals\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eFrames, linings and finishes to choose from\u003c\/h3\u003e\n\u003cp\u003eA full frame set gives you the complete surround, while a lining set suits an opening that already has its structural frame; check the product to see which each one is.
