Maintaining excellence: quality and certifications

Noise insulation is a fundamental requirement for an entrance door facing a noisy street or the common stairwell of an apartment building. Bauxt believes that it is something more than that as well. We believe that freedom from unwanted noise is a right of our customers. Bauxt armoured doors have excellent acoustic performance, which may be further enhanced to 45 dB RW using specific insulation kits available for the different configurations and models.

Bauxt technology limits heat loss and provides the correct insulation to ensure maximum comfort and reduce energy consumption. Bauxt Thermal Kits easily provide insulation levels of up to 1.6 W/m²K on a number of models, while our Superior model (Kit Zero) offers up to 0.6 W/m²K.

Air tightness is the product’s ability to stop drafts, limit heat losses and reduce noise. Bauxt offers a number of specific dedicated kits that, based on the model, are able to reach level 4, the maximum level attainable.

Wind load resistance measures the deformation of the door leaf and, consequently, its rigidity and strength. Wind load resistance is classified using a number from 1 (worst) to 5 (best) and a letter indicating the extent of the deformation under load, from A (worst deformation) to C (minimal deformation). Bauxt armoured doors can reach classification 5C, the best performance classified by the Standard.

Water tightness requires a high level of technical expertise. It is expressed by the letters npd (when no performance has been determined) or by a number from 1 up to 9 followed by a letter (A – unshielded and B – shielded). To understand the importance of this parameter, one must consider that in order to reach the lower class 1 (A or B), the product must prevent the passage of any drop of water for at least 15 minutes. Higher classes are achieved by retaining water tightness at ever increasing test pressures. When exposure to the elements is especially severe, our Sigillo tightness kit provides a water tightness level class 7A, equivalent a 300 Pa test pressure under fully exposed unshielded test methodology, on the Grand Superior, Elite and Superior doorset models.
