AIR&FIRE STOP® – Our new airtight, fire rated doors

To meet the latest standards and its customers’ needs, SPENLE has recently developed a brand new range of doors that are both airtight and have an EI 30 fire rating: AIR&FIRE STOP®
(Test reports issued by COFRAC-accredited test laboratories)

For greater acoustic comfort in sterile environments

Certain types of surgery can be particularly long and complex and require constant, intense concentration on the part of the surgeons and other medical staff. Noise from outside the operating theatre can disturb doctors, distracting them from their efforts.

It is to protect surgeons against this type of disturbance that SPENLE has developed its STILLROOM® doors. These doors are not only airtight to maintain the sterile conditions and protect the patient, but they also feature enhanced acoustic insulation – achieving noise reduction of up to -40dB on certain models (tests carried out and test reports issued by the COFRAC-accredited CSTB test laboratory).

The STILLROOM® doors were designed taking account of the mass law and by creating a mass+spring+mass system.

Above all, these are hermetically sealed doors featuring excellent peripheral seals. In addition, the door frame and leaf are also modified and filled with different types of heavy, absorbent materials in order to absorb and attenuate vibration and sound waves. The porthole or vision panel will also be made of acoustic glass.

SPENLE produces two types of soundproof, airtight doors:

The swing doors can reach a noise reduction of up to -35 dB, while the sliding doors can even achieve a sound attenuation of up to -40dB.
