LbL Windows' focus is the design and manufacture of high quality, innovative window products for the long-term performance and satisfaction of the homeowner. Every window is custom manufactured to the exact specifications to allow a perfect fit whether replacing your existing windows or installed as new construction.

LbL Windows' products offer high insulating efficiency multi-chambered frame designs with heat fusion welded frame and sash corners providing maximum strength plus dual weather-stripping to eliminate air and water infiltration. 80% of a window is glass. We have designed the Insulated Glass (IG) units to maximize thermal efficiency by eliminating metal spacers and introducing a non-metal "Warm Edge" spacer system that reduces condensation plus a dual seal spacer (acrylic seal structural bonds glass and secondary butyl moisture seal) that reduces noise and extends performance life well beyond that of metal spacer systems. Many high-performance glazing options are available to further enhance thermal or sound efficiency and/or beautify windows to your individual requirements. Unique matching, craftsman beveled exterior designs offer continuity while creating elegant classic lines.

LbL Windows' Lifetime Guarantee provides parts and labor for the original homeowner and transferable for two years to the second owner.
