The Reliable Sealing Performance of Modern Insulated Sectional Doors

You need to properly control your building envelope in industrial and commercial settings. A poor envelope leads to air leakage, condensation, thermal bridges, wasted energy, and an uncomfortable workplace. Sealing is today a key part of building the so called ‘envelope door’ composed of the most advanced materials and engineered to ensure climate within the building is controlled. The tight sealing and robust construction with advanced seals ensure the door provides an impermeable barrier from external conditions. To keep your insulated sectional doors perform under every kind of conditions, from cold storage to manufacturing applications where a precise temperature is important Seppes Door has been invested more in sealing technologies.

Precision Panel Interlocking for Continuous Protection

The first line of defense to a good looking sectional door is sealing between the individual panels. The common way to build a door has gaps or joints through which heat and moisture can pass the building envelope resulting in loss of effective insulation and thermal bridging. The modern insulated sectional door does this with precision engineered panel joints that fit together to create a complete thermal barrier on the surface of the door. The joints are constructed in such a way that air cannot enter through them even if a material expands or contracts because of changes in temperature. With advanced manufacturing techniques, and precise tolerances on joints and dimensions, Seppes Door ensures that each panel fits perfectly with the other. This careful attention to detail allows no gaps to form which could let conditioned air out of the room or the outside air into the room, thus ensuring that the interior remains intact.

Comprehensive Perimeter Weather Seals

Although joints panel may give us an answer on the sealing, the doors’ boundary may bring an even bigger challenge on the sealing. Completely airtight insulated sectional door with a complete system of weather-seals around the sides of the door, top and bottom, which is airtight when the door is closed. They are sturdily built and are made from very robust elastomer materials such as EPDM which are sufficiently strong enough to withstand and be resilient for so many extreme temperatures. The sides and the tops of most sliding door systems are protected by substantial retainer that holds constant pressure on the door panels, helping to take up minor misalignments or any building settling that occurs over time. The lower seal and its ability to conform to the hard and uneven surfaces of the floor is particularly important, as is its ability to close. A thick,

bottom seal elastically conforms to irregularities in the floor to provide a secure seal and minimize drafts, dust and humidity from entering the facility, Seppes Door provides a reliable seal.

Thermal Break Technology for Condensation Prevention

In addition to air leakage, thermal bridging is a big problem to sealing. Heat transfer can be transferred easily from interior to exterior side of a door if both sides are connected by conductive material and cold spots could occur there and condensation would occur. This is solved by the use of insulated sectional doors, which come with thermal insulation. Thermal breaks are included in the conductive path to resist heat transfer from exterior to interior. This design will cause the interior air temperature of the door to slightly adjust when the air temperature difference between the interior and exterior of the door is large. Seppes Door has included condensation prevention measures into its sectional door designs; resulting a condensation free interior surface which does not impact upon the sealing performance or cause water damage. It's a technology that's proving very popular for refrigeration where the ambient temperatures and temperatures on the inside can differ substantially.

Durability of Sealing Components Over Extended Service Life

Sealing system should be effective immediately after installation and should continue to be effective for years to come. The construction of our insulated sectional doors with durable components allows you to count on excellent sealing for the lifetime of the door.

This atmospheric seals have been created with opposition against ozone, UV and chemicals in request to guarantee they combat premature hardening, ageing, and breaking from weathering. The mounting systems of these sorts of seals make checking and repairing the seal as required an easy task, so ensuring a wonderful sealing performance without having to change out the entire door. Seppes Door's commitment to quality is reflected in its product warranties and insurance cover, as well as the extensive testing to ensure long lasting performance of their sealing materials. This also means that the insulated sectional door will ensure the facility space and its contents are protected for decades, with its reliable sealing performance.
