| Applications |
| The terminals prevent rain penetration and, used in conjunction with internal ventilation grille(s), also provide through-ventilation to prevent condensation |
| Benefits |
- An effective and simple method, requiring minimal alteration work, for maintaining the structural integrity of an un-used chimney over an extended period
- Available in red, buff and blue/black
- Colours will not fade
- Ventilation terminals are resistant to frost and the freeze/thaw cycle
- Chemically treated to prevent efflorescence

| Materials |
| Ventilation terminals are made of terracotta formed from specially selected clays for long-term in-use stability and durability. |
| Specifications |
| The ventilation terminals are tested to, and satisfy, BS 1181: 1989 "Specification for clay flue linings and flue terminals". The tests cover compressive strength criteria, resistance to acid attack and air permeability. |
