X-ray Protective Observation Windows

We manufacture X-ray protective observation windows to give full protection to the total structural opening based on the energy emitted by the X-ray or Gamma source. The structure and shielding composition of the surrounding walls together with the work procedures of each specific room are also taken into consideration.

Window frames have a similar construction to those used for doors and are offered in a selection of hardwoods for paint or sealed finish and in profiles to match other frames. Frames are produced with any thickness of lead lining. The most popular being Code 3 (1.32mm) and Code 5 (2.24mm). Multiple windows can be produced with leaded 'H' bars at the glass joints or frames divided by leaded timber mullions, as shown in the images above.

The picture above shows a 22mm lead observation window installed at the Wolfson Institute at Hammersmith Hospital, London. The three sections are joined by protected mullions and sit in an overall leaded frame 3000mm x 1000mm. Even though the window consists of multiple layers of lead glass it retains excellent clarity.

Lead glass is available from stock in a selection of thicknesses. We are pleased to manufacture windows in any size. However, in view of the high cost of lead glass we are listing glass sizes available from our bulk stocks offering the minimum amount of wastage.

Non-standard sizes are available to special order. Please contact our sales office for further information.
