White Coventry door fitted in a room opening

Measure the opening carefully, choose a listed size that will not need excessive trimming, and have the door hung with the correct gaps, seals and closer. Vizat lists standard 1981 mm and 2040 mm fire door sizes, plus linings, and explains on its FAQs that you should check the lipping before planing. This guide covers measuring, the principles of a good fit, and the published delivery, warranty and returns terms.

This article is general guidance, written with England in mind, and is not legal advice. Fire door requirements depend on the building, its use, the fire strategy and the fire risk assessment. Rules in Scotland, Wales and Northern Ireland can differ. If you are unsure, take advice from a competent fire safety professional before you buy or fit a door.

Measure the opening, then choose the door

Before you order, measure the opening or the existing lining at several points and note the smallest width and height. Check that the opening is reasonably square, and allow for the floor finish and for the gaps a fire door needs at the sides, head and threshold. There is a fuller measuring note, including the millimetre sizes Vizat lists, in our fire door sizes guide.

Choose a listed size that can be fitted with only the trimming the lipping allows. Do not order a door that is obviously too large in the hope that it can be cut down to suit.

Fitting: the points that matter for a fire door

This is a checklist of principles, not a step-by-step installation method, and it is not a substitute for the manufacturer’s instructions or BS 8214.

  • Frame or lining. The leaf needs a suitable frame. If you are replacing the lining, Vizat lists FD30 and FD60 linings in Frames/Lining. A twisted or loose frame will not give even gaps.
  • Gaps. Aim for the even, modest gaps described in the door instructions. Vizat’s maintenance article mentions a typical 3–4 mm gap between door and frame.
  • Trimming. Only trim within the lipping. The FAQs page tells customers to check that thickness on the item. Repeated hanging and small adjustments are normal; grinding into the core is not.
  • Seals. Intumescent (and, where required, smoke) seals must be the right size and in the right position, continuous and undamaged. See Intumescents if they are supplied separately.
  • Hardware. Fit suitable hinges, a latch that engages, and a closer that fully shuts the door from any angle. Handles and additional ironmongery are not included with the leaf on the door pages reviewed — see our ironmongery guide.
  • Keep the door identifiable. Do not plane, fill or paint over any fire-rating plug or label if the door has one. Official guidance expects fire doors to remain identifiable.

Warranty, delivery and returns

Vizat’s warranty page states: “10 years company warranty will be provided by the Product manufacturer (Deanta, XL Joinery, and LPD Doors). Please note Warranty is 5 years for glass and hardware.” Read that page for the published terms, and ask if you need to know how they apply to a specific door.

Delivery is nationwide, typically dispatched in 3–10 working days, from £2.95, with England charges of up to £96 including VAT. Someone must be in to receive the order; heavier doors may need help or a requested tail-lift. The returns policy explains damaged or incorrect goods, and the 14-day change-of-mind process, including that the customer pays to return unused goods.

Frequently asked questions

Can I fit a fire door myself?

Hanging an ordinary internal door is a common DIY job; hanging a fire door is more exacting. Gaps, seals, the closer, the frame and any trimming all affect performance. If you are not competent in fire door installation, use a specialist. Poor fitting can waste a correctly specified door.

How much can I trim off a Vizat fire door?

Vizat’s FAQs page says planing is often needed and that you should check the lipping thickness on the item to see how much can be taken off. There is no single published allowance for every door in the range. Never trim into the core or beyond the manufacturer’s instructions.

What gap should there be around a fire door?

Vizat’s maintenance article gives a typical figure of 3 mm to 4 mm between the door and the frame. Threshold gaps, especially where smoke control is required, can be more tightly controlled. Use the door’s instructions and BS 8214 rather than a guess.

Does Vizat fit the doors it sells?

The pages reviewed describe supply, delivery and returns, not an installation service. Delivery information notes that customers must be present to receive the order and that heavier items may need help to offload. You will need your own competent fitter unless you have agreed otherwise with Vizat in writing.

What if the door arrives damaged or I need to send it back?

Inspect the goods on arrival and follow the returns policy. Incorrect or damaged goods should be reported to info@vizatdoors.co.uk within three working days, with photographs. A change-of-mind return must be notified within 14 days of delivery; the customer arranges and pays for the return, and the goods must be unused and in a re-saleable condition. Customised items are treated differently, as the policy explains.

How long does delivery take?

The delivery information page says orders are typically processed and dispatched within 3–10 working days. Charges start from £2.95 and, in England, go up to £96 including VAT (quoted there as 7–10 business days). Extra charges may apply in Scotland, the Highlands and islands, and the team will contact you if so. Orders placed after midday on Friday are processed the following Monday.
