Shielding, honestly

Most surgeries need less lead than they are sold.

Distance and existing construction do a great deal of the work, and plenty of intraoral rooms need no lead in the door at all. Your Radiation Protection Adviser decides what is required — we build to that assessment and evidence what we built. If the answer is that you do not need a leaded door, we would rather tell you than sell you one.

Inside a Cabentra X-ray door

Layer 01 · Finish · 0.6 mm veneer / 0.8 mm HPL / PVC

The face you actually touch

Lacquered veneer, high-pressure laminate, PVC encapsulation or a factory primer for site paint. In a surgery this is a hygiene surface before it is a decorative one — it has to survive daily wipe-down with clinical detergent, so it is specified to HTM 58 and sealed on every edge.

Layer 02 · Facing board · 6 mm MDF, both faces

The board that keeps it looking like a door

Lead is soft and lively. Bond a veneer straight onto it and every roller mark and fixing telegraphs through within a season. The board also gives ironmongery something to bite into that isn't the sheet.

Layer 03 · Lead · Code 3 = 1.32 mm Pb

One sheet. No joints.

Cut oversize from a single sheet and bonded to the core, so the protected area runs past the finished leaf on every edge. Where a join is unavoidable on a large leaf it is lapped by a minimum of 30 mm and its position recorded on the build sheet. A butt joint is a hole with extra steps.

Layer 04 · Core · Engineered timber / FD30 flaxboard

The core carries the weight

A lead-lined leaf is two to three times the weight of the door it replaces — a Code 3, 838 mm leaf lands around 55 kg. The core has to stay flat under that load for a decade of swings, hold a screw, and do it while fire rated if the room sits on an escape route.

Layer 05 · Second sheet · Code 4–5 specifications

Splitting the lead

Above Code 3 the shielding is usually split across both faces of the core rather than doubled on one. It balances the leaf, keeps it flat, and stops the whole weight of the lead hanging off one side of the hinge line. Equivalence is additive and is stated on the certificate either way.

Layer 06 · Lippings · 18 mm hardwood, lead carried to the edge

Where nine out of ten leaks are

Hardwood lippings on all four edges with the lead carried right into them rather than stopping at the core. This is the single most common defect we are asked to survey: a perfectly good sheet finishing 40 mm shy of the lipping, leaving a full-height strip of unprotected timber down the closing edge.

Layer 07 · Vision panel · Lead-equivalent glass

Seeing in without letting anything out

Glass specified to match or exceed the leaf, never below it. The beading is lead-lined and the glass sits behind an overlap, so the barrier is continuous around the aperture rather than butting up to it.

Layer 08 · Frame · Rebated, leaded, 20 mm overlap

The frame is half the job

Hardwood or stainless steel, with lead behind the rebate overlapping the leaf by at least 20 mm so there is no straight line of sight through the gap at any point in the swing. Lead runs behind the architrave and laps into the wall shielding. Cut-outs are lead-patched before ironmongery goes near them.

Assembled · Certified · Ready for critical examination

One opening. One barrier.

Leaf, lippings, glass, frame and ironmongery leave us as a single certified assembly with its lead equivalence, sheet layout and hardware schedule recorded. Your RPA gets a document that matches what is actually screwed to the wall.

Where doors fail

The join, not the thickness.

Almost every shielded door that fails does so at an edge — lead stopped at the board and never carried into the lipping, or a cut-out drilled straight through the sheet on site. We lay one sheet, take it into the lippings, and patch every cut-out before the ironmongery goes near it.

Compare

What is included as standard.

The difference usually shows up on the day the door is hung.

What is included as standard.
Included Cabentra Typical supplier
Single continuous lead sheet No joins unless the leaf size forces one, and a 30 mm lap where it does Jointed, with no lap specified
Lead carried into the lippings The most common failure on a fitted door Lead stops at the board edge
Rebated leaded frame, 20 mm minimum overlap So there is no straight line of sight at any point in the swing Frame supplied unleaded, or with no stated overlap
Cut-outs lead-patched before ironmongery Locks and closers go in after the patch, never through the sheet Drilled straight through on site
Vision panel with lead behind the beading Glass is only half of a shielded opening Glass specified, beading forgotten
Hinges rated for the finished weight A Code 3 838 mm leaf is around 55 kg Standard hinges, then a callback
Survey before manufacture We measure the opening rather than trust a drawing Ordered from dimensions given over the phone
Fitted by our own team Out of hours can be arranged Subcontracted

Cabentra does not advise on radiation protection. Under IRR17 your Radiation Protection Adviser assesses the shielding for a new or modified installation in advance, and the installation is critically examined before clinical use. We build to that assessment and give you a record of what was built.

How it works

From first call to a door you can evidence.

One team from first call to delivery, and to fitting if you want it.

  1. Week 0

    The call

    Tell us the opening and what your adviser has specified. If there is no assessment yet, that is the call to make before this one — and we will say so.

  2. Week 1

    Measure

    You send the opening sizes and the existing construction, or we survey as part of a supply-and-install quote. Either way we confirm how the lead in the door meets the shielding in the wall.

  3. Week 1–2

    Drawing

    A drawn leaf and frame with the lead line marked, for you and your adviser to approve before anything is cut.

  4. Week 2–4

    Manufacture

    Made in our own workshop. Lead laid in one sheet, lippings applied with the lead carried into them, cut-outs patched before ironmongery.

  5. Week 4

    Delivery or installation

    Delivered by pallet, kerbside or into the room, for your own fitter. Installation by our own team is quoted on request, and out-of-hours fitting can be arranged if the practice is working.

  6. Handover

    Evidence

    A record of what was built and where the lead runs, for your critical examination.

Configure your X-ray door

Standard sizes and specifications price instantly and go straight to the basket. Anything bespoke switches itself to a survey — because guessing at a shielded opening is how practices end up paying twice.

  • Built to the drawing

    The leaf, the frame and the lead line are drawn and approved before anything is cut.

  • Continuity, not just thickness

    Lead into the lippings, a rebated frame with 20 mm overlap, and patched cut-outs.

  • Fitting if you want it

    Shipped for your own fitter, or installed by Cabentra teams on a quoted basis.

  • Evidence at handover

    A record of what was built and where the lead runs, for your critical examination.

A room that gets signed off.

Every door leaves us with a record of what was built and where the lead runs — the document your critical examination asks for. Fitted by your contractor or, by quote, by our own team.

Questions

Asked before every project.

How much lead do we actually need?

Your Radiation Protection Adviser decides that, not us. Under IRR17 the shielding for a new or modified installation is assessed in advance, and we build to what that assessment specifies.

Do all intraoral rooms need a leaded door?

No, and a great many do not. Distance and the existing construction often do the work. We would rather say so than sell you a door you do not need.

What is the difference between Code 3, 4 and 5?

Lead thickness. Code 3 is 1.32 mm, Code 4 is 1.80 mm, Code 5 is 2.24 mm and Code 6 is 2.65 mm. Code 3 is the usual dental specification; Code 4 and 5 appear on CBCT suites.

Where do shielded doors usually fail?

Almost never on thickness. It is continuity — lead stopping short of the lipping, a frame with no rebate overlap, cut-outs drilled through the sheet, or glass with nothing behind the beading. All four are avoidable, and all four are on our standard specification.

How heavy is a leaded door?

A Code 3 838 mm leaf is around 55 kg. That is why we fit a minimum of one and a half pairs of grade 13 ball-bearing hinges rather than a standard set.

Can you match our existing doors?

Usually. Send photographs, or a door, and we will match finish, profile and ironmongery as closely as the materials allow.

Can you work around a live practice?

Yes. Doors ship ready for your own fitter. Where we install, which we quote separately, out-of-hours and phased work can be arranged so the practice stays open.
