Commercial Door Protection

Our Door Seals & Protection service ensures that interior doors, not just their appearance but their performance, live up to demanding standards of acoustics, fire/smoke control, energy efficiency, hygiene, and durability. We advise on and supply sealing systems, drop-seals, gaskets, thresholds, astragals and related hardware to protect doorways against unwanted air, sound, light, odor or fire/smoke penetration. The service covers selection of appropriate seals – taking into account door type (solid, glazed, flush), frame type, gap tolerances, finish, durability – and ensures compatibility with other systems (fire doors, automated doors, building services) and compliance with regulation.

For architects and builders, this means fewer surprises, better control over performance (sound, fire ratings, thermal/seal integrity) and enhanced user comfort. Through careful specification, we help avoid issues like drafts, noise bleed between rooms, smoke spread in a fire event, odours, light spill, or dust ingress. We also provide guidance on maintenance, tolerances, and long-term performance to ensure the installed seals keep doing their job throughout the life of the building.

Our Door Protection Solutions

• Assessment of door-jamb and door-leaf geometry to identify sealing challenges: gap sizes, surface finishes, frame fit, threshold detail.

• Specification of internal sealing solutions: drop seals (automatic bottoms), brush or pile seals, adhesive or kerf seals, gasketing, astragals, thresholds as needed.

• Advice and selection for fire and smoke sealing: intumescent strips, smoke gaskets, fire rating compatibility, testing/certification.

• Acoustic control: selecting seals that help achieve required Sound Transmission Class (STC) or decibel-reduction targets.

• Thermal / energy sealing: reducing air leakage, drafts, improving efficiency of heating / cooling, aiding building energy performance.

• Light, odour, dust and insect sealing: for spaces such as corridors, hospitals, hotels, specialized rooms (e.g. toilets, kitchens, labs).

• Material, finish, and durability guidance: choosing seals that suit the door material, finish, expected traffic or wear, maintenance environment.

• Coordinated specification with other systems: ensuring sealing solutions align with other door hardware (locks, closers, automated operators), flooring / threshold transitions, fire & smoke control elements.

• Compliance & standards: guidance on relevant codes & standards (fire door regulations, building regulations, acoustic and air-permeability standards) to ensure legal/regulatory compliance.

• Support for tender documentation & schedules: providing the detail needed in specifications, door schedules, hardware schedules so that contractors understand what is required.

• On-site or during construction review / quality assurance: checking that installation meets tolerances and detail so seals perform as specified (e.g. seals properly compressed, drop-seals adjusted, finish between door and frame correct).
