Quartz TimberLine Windows & Doors

Timeless comfort.

Nothing can beat the elegance and natural feel that wood windows provide. The TimberLine series of windows and doors is the perfect merge of enduring style and modern components.


A warm welcome that complements your home.

The TimberLine series fuses an architectural aluminum exterior with a classic natural wood interior to provide ageless charm for your living space while permanently protecting your inside from the outside.


The TimberLine series windows feature Quaker® patented OptiCore® Technology, an architecturally enhanced aluminum frame design that maximizes the thermal, structural and sound performance of each window.


Originally engineered for large commercial buildings, OptiCore® Technology offers the most advanced thermal barrier system available for residential applications to maximize energy performance, while allowing for bigger windows and greater views throughout your luxury home.

Framed to perfection.

TimberLine windows and doors can be designed to fit any space or configuration. High quality framing components mean that your windows and doors are as strong and safe as the rest of your home’s unique features.

Uncompromised Construction.

The Quartz™ TimberLine series is engineered with the most structurally and thermally advanced architectural aluminum components, offering customers superior design flexibility and structural integrity.

TimberLine windows with OptiCore® are tested to achieve an FGIA (formerly AAMA) certified AW architectural rating based on both the windows maximum design size and gateway test size. Therefore, no matter the size and structural requirements of your new luxury home, your windows will perform to desired performance.


The TimberLine series utilizes a sealant-injected double corner key construction for maximum strength in the corner joinery and frame. This composition ensures that every window and door will provide superior performance while offering flexibility in configurations to meet your architectural style.

Never fades, never rusts.

Proper corner joinery construction is essential for two reasons — ensuring a window’s stability and maintaining a water-tight seam.
