All our interior doors are built to high standards, featuring a 7mm MDF exterior. For the door’s interior, you can choose between our standard construction or a premium core upgrade:
Standard Core (Honeycomb): Our factory-standard option. It provides a lightweight yet stable structure, perfect for everyday residential use.
Tubular Upgrade: For those seeking enhanced performance, we offer the perforated particleboard core upgrade.
Increased Sturdiness: This core adds weight and a “solid” feel to the door, making it significantly more durable and robust.
Superior Insulation: The material’s density greatly improves sound insulation, effectively keeping noise out of your private space.
Compatibility: This upgrade is available for the following models: Suite, Rita, Mira, Quore, and Suite Slide.
