Premium Design

All SonoTec doors have equally sized stiles and rails, which provides a balanced 65mm perimeter framing to the elevation of the door. This is fabricated from our bespoke aluminium extrusions which can be polyester powder coated or anodised in a range of colourways. The glazing is positioned near on flush to the outer faces of the door, which provides a stunning sheer appearance to the door leaf.

01 – Lever lock ironmongery in satin stainless steel finish (pull handle also available)
02 – Maximum acoustic performance is achieved using DGU sealed unit glazing
03 – Door perimeter frame is almost flush with glass and only 63mm wide in elevation
04 – SonoTec doors are compatible with all Planet systems, p20, p54 and p100
05 – Concealed overhead door closers can be factory installed to avoid the use of floor springs

The SonoTec range is availible in both single and double glazed versions. Using single glazing with 10mm glass, our base model provides 35dB Rw sound attenuation. This can be enhanced by specifying alternate glass configurations that provide 36, 38, 40 and 42dB Rw. Additionally, SonoTec can be provided in double and hospital set formats if required.


Ironmongery Options

A full range of ironmongery options are available to select from. Pull handles can be cranked and affixed to the 65mm perimeter frame, or alternatively bolted through the glass on single glazed versions. If locking is required, our extra slim cylinder lock case is installed within the vertical stile – avoiding unsightly intrusion to the visible glass area. All SonoTec doors are fitted with automatic drop down seals for acoustic attenuation and if required, concealed overhead closers can be specified.
