AG Millworks Multi-Slide Patio Doors & Windows are your gateway to indoor-outdoor living. Narrow site lines create expansive exterior views. Made in the USA, our doors and windows are energy-efficient and fully customizable. Nothing is more beautiful than big sliding glass doors and windows that transition smoothly past each other and stack neatly at the edge of an opening, or disappear completely into wall pockets! Exquisite wood surfaces on the interior provide warm, luxurious design details. Thick extruded aluminum exteriors with durable baked-on Kynar paint in any imaginable color completes the picture. Also available with wood exteriors (limited warranty). Expand your world view with AG Millworks Multi-Slide Patio Doors & Windows.

Title 24 Compliant
Title 24 Compliant

Title 24, a component of the California Code of Regulations, establishes guidelines for building energy efficiency. Its objectives include lowering energy consumption, cutting utility expenses, safeguarding the environment, and mitigating climate effects. The standards outlined in Title 24 assess the energy efficiency of buildings comprehensively, covering various elements such as windows, doors, lighting, appliances, and electrical and mechanical systems. The California Energy Commission (CEC) oversees the adoption, implementation, and revision of energy efficiency requirements outlined in Title 24. Local municipal and county bodies are tasked with ensuring adherence to these standards through verification and enforcement measures.

The California Energy Commission periodically revises the energy standards to accommodate the evaluation and potential integration of emerging energy-efficient technologies and methodologies. Our AG Millworks Door and Window Systems have consistently met or surpassed each revision of the California energy-efficient standards.

Pocketed vs. Non-Pocketed Sliding Door

For the ultimate indoor-outdoor lifestyle, Multi-Slide Patio Doors can be completely concealed in the wall when opened.  Paired with our flush lock with a pop-out finger pull, Multi-Slide patio doors can be neatly tucked into a pocket on one side of the wall!  Pocketing Multi-Slide patio doors are also available in Aluminum Clad/Wood with hundreds of custom colors to choose from.
