An expansion to our range of GRP Fire Doors! This post covers our new Lead-Lined and Hermetic GRP doors, primarily suited for medical areas, so are great hospital doors, operating theatre doors and labatory doors. Check them out!


Ulti Group has a range of seamless x-ray doors that are ideally suited to hospitals, laboratories and other clean areas where hygiene and x-ray protection are of utmost importance.

Our Lead-lined door sets incorporate lead sheeting in a range of thicknesses. This protection extends through the door frames, forming an effective barrier to radiation in all directions. These specialist lead-lined doors can be supplied in a wide variety of styles and specifications to meet resistance to the passage of x-rays in accordance with international codes and standards.

Our x-ray doors have a smooth and seamless construction which is free from voids or ledges where bacteria can build up. All doors are manufactured to have an equal appearance to doors without lead protection. Our x-ray doors are available with fire resistance, sound reduction, air pressure control and lead-lined vision panels.

These air-tight sliding doors have been specifically designed for use in Operating Theatres, Isolation wards, Mortuaries, X-ray and Recovery rooms. Sliding doors require much less space than hinged doors and when operated produce far less air disturbance as they slice through the air. When closed the unique patented track system allows the door to move down/in under its own weight(see bottom right picture) and in conjunction with a continuous neoprene gasket it seals perfectly against the floor and frame.

The efficiency of the seal has been officially tested and results show it to be over 99% effective thus helping to reduce air handling costs, the incidence of wound infections and cross contamination. Furthermore, sound insulation is significantly increased giving quieter conditions for the medical teams and increasing patient comfort.

Key Features of a Fiberglass Hermetic Door:

• Controls air leakage
• Lower air handling costs
• Reduces cross contamination
• Smooth hygienic surface
• Safe, reliable, low maintenance
• No floor track required
• Good sound reduction creates quiet working environment

Sliding doors vs hinged doors:
Traditional swing doors create uncontrolled movements of air
during opening and closing. This uncontrolled air can accelerate
the spread of airborne micro-organisms by air currents and may
infect susceptible hosts in operating theatres and isolation wards.


Patented Track System:
The unique patented track system is angled at 45 degrees and special indentations allow the bearings to roll down and in enabling the door using its own weight to seal perfectly against the frame and floor.
