Supply ventilation valve is intended for in-wall installation in residential and office premises. The valve prevents the intrusion of foreign particles, insects and reduces the noise level supplying the fresh air. Supply valves are an inseparable part of urban ventilation systems. The duct length is in a range from 400 mm to 1000 mm, with a pitch of 50 mm. The inner duct diameter is 125 mm.
- Modification-01: Mineral wool thermal insulation on the basis of basalt rocks, laminated with reinforced aluminum foil. It possesses enhanced protective properties and has a self-adhesive foil overlap, which simplifies the mounting process.
- Modification-02: Mineral wool thermal insulation on the basis of basalt rocks. Fire-resistant, non-toxic, transpiring material provides reliable sound insulation and does not change shape with time.
- Modification-03: Thermal insulation made of polyethylene foam. Elastic material with a closed cellular structure possesses better insulating properties and it is characterized by high humidity and damage resistance.
