Tempered glass is ideal for reducing the likelihood of injury in the event of breakage in applications like patio doors, sidelites and bathroom enclosures for showers and tubs.
- Laminated – Laminated glass is highly effective in reducing noise. It also eliminates 99.9% of ultraviolet rays, providing the highest degree of protection from the sun for your home furnishings.

Every window project is different. It's hard to provide an accurate cost range as a house can vary greatly in the number and size of its windows. Costs also depend on the frame material and glass options. Double and triple-glazed windows, or those filled with argon gas, increase energy savings but add to initial upfront costs. Often government or power company incentives include additional tax deductions or rebates for making energy-saving improvements to your home. These incentives may significantly reduce a project's total costs. You may be pleasantly surprised to discover how affordable a window replacement project can be.
