Air Sealing Services

Uncontrolled air leakage is one of the most common causes of heat loss, draughts and failed airtightness targets within modern buildings. ROSEAL provides professional air sealing services across the South West, helping residential and commercial properties improve airtightness performance through precise joint and gap sealing.

We work on both new-build and refurbishment projects where airtightness and building envelope performance are essential.

Improving Building Airtightness

Small gaps around construction joints, frames, penetrations and interfaces can significantly affect a building’s energy efficiency and air pressure performance. Effective air sealing helps reduce unwanted air movement throughout the structure while supporting compliance with modern building standards.

Our air sealing services are suitable for:

  • New build developments
  • Commercial buildings
  • Residential properties
  • Refurbishment projects
  • Modular construction
  • Internal fit-outs
  • Building envelope systems
