What are gap seals?
Gap seals are flexible sealing profiles that are installed between the door and the frame to reliably close openings. They are indispensable for sectional doors , sliding doors , steel doors , and loading equipment .
They reduce energy losses, stop drafts, block dust and moisture, and act as a barrier against rodents and insects – ideal in autumn/winter and wherever sensitive goods are stored.
What problems do gap seals solve?
Protection against cold & energy loss
Gaps are energy guzzlers: warm air out, cold air in. Seals for sectional doors reduce heating costs and improve the indoor climate.
Avoiding drafts
Drafts impair comfort and health. Seals on sliding and steel doors provide relief.
Protection against rodents & vermin
Mini-openings are sufficient for mice and insects. Seals for loading equipment secure ramps, docking stations, and storage areas.
