Sound insulating and fire-resistant doors

Alara-Lukagro sound insulating and fire resistant doors type AL-D are designed according to a large number of demands, developed for a many different applications in both industrial as well as architectural building. The quality of our sound insulating doors guarantees optimum user friendliness, extended lifetime, good value for money and obviously supreme sound insulation.

Sound insulating doors type AL-D

The sound insulating doors type AL-D are equipped with double layer door panel, made out of pre-galvanised steel sheet. Optionally doors can also be made of cast aluminium or stainless steel in different grades. All door panels have a thickness of 80 mm and have identical looks, so doors with different acoustic properties can be easily combined without it being visible.

To ensure an optimum sealing we apply specifically designed rubbers. Door type AL-D 45 has a single sealing, all other models have double sealing. Depending on location and application you can choose different designs of threshold:

• standard threshold (in combination with AL-D 45 only)
• standard threshold with double sealing
• extra low threshold
• automatic drop threshold in combination with flat floor plate

For application in exterior walls the thresholds are also available in protruding design, providing optimum watertight integrity.
