Door leaf with recessed 7 mm square lock. Galvanised sheet steel, coated white (RAL 9016).
Tested for air permeability according to DIN EN 1026 and DIN EN 12207. Test results in the best classification level (window class 4). Tested for airborne sound insulation in accordance with DIN EN ISO 10140-2. The measured sound insulation value is Rw 31.8 dB. The Softline Iso access door is equipped with a special insulation inlay in the door leaf. After closing the square lock, this inlay seals the access door airtight to the mounting frame. In addition, the insulation inlay contributes to better sound and heat insulation. The steel components of the access door are galvanised and subsequently powder coated in RAL 9016 (Traffic White). This provides the access door with double and very good corrosion protection.
