Punched window Systems AT 740 SI

The AT 740 SI system for windows achieves the best thermal insulation properties thanks to the insulation variant. Various types of opening, such as turn, turn-tilt, faceplate, PSK, folding, etc. can be implemented by you with commercially available fittings. Cross-system accessories are largely compatible with other AKOTHERM systems. You can press or peg the corner connections together using corner brackets.

Your advantages:

• Maximum compatibility with existing AKOTHERM systems
• Security through burglar resistance
• Highest thermal insulation
• Barrier-free passages can be implemented
• Proven and established manufacturing technology
