DESCRIPTION
This series of high quality profiles with thermal break are applicable where more severe standards of acoustic and thermal insulation are required. The profiles for this series are constructed by polyamide strips PA 6.6.25 reinforced with glass fibre. The Steel Lokk is different from other window systems due to its slim sight lines that mimic those common to steel profiles.

APPLICATIONS
- fixed frames for single or double glazing
- single or double sash, side-hung, open in windows
- internally open tilt in windows
