Industrial buildings are extremely loud premises. The sounds of equipment, forklift, loading equipment, trucks, and the constant sound of equipment can go over safe listening levels and contribute to employee fatigue, stress, and decreased productivity. Although a great deal is done in the facility to control noise, the building envelope helps control actions inside and outside the building. Perhaps a rarely considered cause of unwanted noise would be the door of a loading bay door – this often has terrible acoustic characteristics as an enclosure. This is where the insulating overhead sectional door really has great benefits. This type of door is incredibly dense, features well-designed sealing systems and has the material properties to help create a quieter and more comfortable work environment. Seppes Door products that incorporate insulation have been developed to provide outstanding acoustic performance with all the benefits of insulation and durability that can be achieved when the door is in use.
Dense Panel Construction as a Sound Barrier
The basic premise of noise reduction is that mass is what is most effective at reducing vibrations which travel through materials. The insulated overhead sectional door consists of thick steel sheets and a dense polyurethane foam core which can effectively cut down the noises caused by the door itself. The reflective layer of steel soundproofs reflects considerable acoustic energy, and the absorbent and dissipative layer absorbs and dissipates the rest of the energy, so that there is no sound that can pass through the layer of steel panels. This is much better than single panel or roll-up doors that are thin and have only a small mass and only do a little to block sound. The high-density foam cores that Seppes Door uses don't only offer superb thermal insulation but also promote noise dampening to make a door effective acoustic barrier. The outcome is a significant decrease in noise penetration from outside to inside the premises and inside to neighbors, shielding the staff from the noisy traffic outside and keeping the noise of the equipment inside from bothering the community outside.
Sealing Systems That Prevent Sound Leakage
A good door panel doesn't count for much, unless it has good seals. Sound transfer can occur through very narrow spaces and air leakage can be an acoustic leakage pathway. The insulated overhead sectional door does so with extensive perimeter sealing systems that seal air and sound. The interlocking panel joints form unbroken barrier walls to stop sound from crossing between panels, and the complete perimeter weather seals fill gaps around the edges of a door to seal off the permeable space. These are made of heavy elastomeric material and when they engage with the door panels and building frame, they create an airtight seal that also blocks the transmission of sound. Seppes Door uses robust seals which provide optimal function over the years since installation, without compromising the acoustic performance of the door. Such sealing integrity is especially important in all-suite facilities that are situated close to heavy traffic roads, railways, or residential neighborhoods, where noise control issues may be a part of the regulations or community relations.
Vibration Dampening Through Insulating Core Materials
Noise generated by industrial buildings may appear not just as airborne sound, but as structural borne vibrations too - a major component in their noise profile. Vibrations from the operation of machinery, movements of truck and equipment and impacts cause the vibrations to pass through the building structure giving rise to noise. The insulated overhead sectional door is designed to reduce this effect thanks to the insulating core which reduces vibrations. The polyurethane foam core can absorb the vibrating energy, which will not be transmitted through the door panels and carried through the door into the building structure. The calming vibration and resonance dampening of our construction, provides a much less echoing environment than solid constructions and avoids the risk of door resonance. The precise manufacturing of panels and fittings ensures that Seppes Door operates vibration-free, vibration dampening in difficult environments. Through vibration reduction, sound in and between the production areas is minimized.
Operational Quietness Through Smooth Mechanics
In addition to the looks of being insulated, this sectional door actually performs insulation silently! Smooth mechanical operation combined with sealed, precision-bearing low-friction tracks and rolling results in little mechanical sound as the panels operate. Unlike other door mechanisms, torsion spring systems do not clatter and bang. The noise from the motor is isolated from the building structure by having vibration isolators installed on the motorized operator. The use of soft rubber rollers, quiet soft start/soft stop motor controls and track silencers creates quieter operation in Seppes Door Sectional designs. This silent mode is very welcome when doors in buildings have a frequent open and closing rhythm, and noise generated during several operation cycles becomes significant for overall indoor building acoustic atmosphere. Therefore, by not only eliminating sound passively, but also reducing acoustic noise that is generated through the door action itself, the overhead insulated sectional door greatly improves the audiologic atmosphere inside the factory.
