18×40 Slim-Profile Utility Window
Narrow Elegance. Precision Airflow. Space-Saving Light. The 18″ x 40″ window is the “slim specialist” of the window world. At just 18 inches wide, this unit is designed to fit into those narrow wall cavities where a standard window simply won’t go. In Michigan, this size is highly valued for its ability to add vertical light and ventilation to tight spaces like bathrooms, walk-in closets, and stairwells without requiring major structural changes to your framing.
New Inventory: High-Performance Vinyl
We stock Brand New 18×40 units engineered to provide maximum efficiency in a compact footprint:
- High-Impact Vinyl Frames: Built with UV-resistant, multi-chambered vinyl that won’t chip, peel, or warp, even when exposed to the harsh Michigan sun or freezing lake-effect winds.
- Advanced Thermal Protection: These units feature insulated dual-pane glass, helping you eliminate drafts in small rooms and keep your heating costs down during the long winter months.
- Plug-and-Play Installation: Designed with integrated nail fins, these new units are a breeze to install in new construction, shed builds, or garage additions.
Used & Surplus: Budget-Friendly Utility
Our Used 18″ x 40″ windows offer an incredible opportunity to upgrade your space without the retail price tag.
- Unbeatable Savings: This is a specialty size that can be expensive to special order. Our surplus stock allows you to get pro-quality glass at a fraction of the cost.
- Pro-Quality Inspection: We verify every used unit to ensure the seals are tight, the glass is clear, and the frame is structurally sound and ready for install.
- Sustainable Choice: Choosing used or surplus inventory is a great way to save money while keeping high-quality building materials out of the landfill.
