Compare glass and acrylic options

Clear glass: A transparent glass panel for a clear view.
Low-E glass: Glass with a coating that reduces heat transfer.
Acrylic: A lighter plastic panel. It needs gentle cleaning because it scratches more easily than glass.
Tempered glass: Safety glass that breaks into small pieces.
Tempered Low-E glass: Combines safety glazing with a heat-control coating.
Laminated glass: Glass layers bonded around an interlayer that helps hold broken pieces together.

The window is close to a door or floorCheck this if the glass is within 12 inches of a door or 18 inches of the floor. These locations require acrylic or a suitable safety-glass option.My opening has an unusual shape or fitCheck this for a bowed sill, uneven corners, obstructions, or a shaped opening. These details need review so the panel fits correctly.I need a dividing bar or an additional exterior screenA mullion is a bar that separates multiple panels in one opening.

What's built into the frame

Side-to-side operation. Two sashes slide in vinyl tracks, with a left- or right-opening layout to match your window.
Tracks that seal. The vinyl tracks act as weatherstripping, and the sash edges interlock where they meet to cut drafts.
Adjustable alignment. Removable track components let the alignment be adjusted for a smooth glide.
Durable vinyl frame. A vinyl frame made to the size you enter and mounted on the room side, so the outside of your home looks the same.
Glass options. Choose clear glass, or add Low-E, tempered, acrylic or laminated glass for energy performance, safety or UV protection.

FAQs

Can I keep my existing windows?

Storm windows are an additional layer for existing windows. Check that the primary frame is sound and address rot, leaks, or other damage before adding a storm window.

Which opening style should I choose?

Match the way you use the primary window: vertical operation for double-hung openings, horizontal sliders for side-to-side operation, and fixed panels where ventilation is not needed. Confirm clearances before ordering.

What affects the price?

Dimensions, glass, frame finish, and configuration affect product pricing. Oversized openings and specialty details may need a quote. Shipping, tax, and installation are separate.

How should I measure an older opening?

Measure each opening at the intended mounting position and keep readings from multiple points. Record mounting depth, obstructions, and any out-of-square conditions. Follow the guide for your selected product before confirming manufacturing dimensions.

Can I get help with installation?

Review our installation information or contact us with photographs and measurements. Homeowners can request a separate installation quote; availability and project requirements need to be confirmed.
