Technal Patio Door Solutions

For patio door applications, Dortech can utilise Technal SOLEAL Next where a hinged patio window or residential balcony door arrangement is required, or Technal SOLEAL Slider where a customer requires a sliding patio door system.

This gives architects, contractors and developers flexibility to specify the right Technal solution for apartment balconies, residential developments, commercial terraces, offices, hospitality projects and mixed-use buildings.
