- Energy saving, low maintenance design: Our glass block windows effectively eliminate the need for storm windows and reduce the energy required for heating and cooling. Glass block does not require additional the caulking, puttying and painting that typically accompany weatherizing window fixtures.

Glass Block Windows versus Single Pane Window
- Comparing a Seves Glass Block Window to a single pane window, (1/8” flat sheet):
- Energy efficiency: Glass block is comparable to a double pane window, eliminating drafts. Single pane has minimal insulating value.
- Window treatment: Glass block privacy is controlled by pattern selection, so no treatment is required.
- Security: Glass block resists breakage and reduces the risk of forced access.
- Replacement: One glass block can be replaced rather than an entire single pane window.
- Water penetration: Sometimes an issue for below-grade single pane installations, glass block offers increased water resistance in these scenarios.
- Cost: Glass block is comparable – or less expensive.
