Q 5:	What about strength, protection and noise reduction?
A 5:	•  Our computer controlled process provides superior strength in both the main-frame as well as a perfectly square window sash.
	The full interlock at the meeting rail provides energy efficiency helping to protect your home from the elements or unwanted intrusions. The insulating glass traps dry air, creating an exceptional comfort barrier.
	Additional sound and intrusion barriers are created at the point where the upper and lower sashes meet with our full interlock system.
