DYC is now using Allerguard 100® weatherstripping system that resists and kills allergy-aggravating microparticles of pollen, fungi, mold, mildew, dust, dirt and bacteria. Allerguard 100® also helps prevent the infiltration of exterior odors and gasses such as carbon monoxide.

When you specify DYC windows for your new home or remodeling project, you are getting a patented, revolutionary anti-pollution/anti-allergy/microparticle-avoidance barrier pile insulating system. Make your home or office healthier, cleaner, quieter, and more energy efficient by selecting DYC windows with Allerguard 100® - The Pollution Solution.

Low-E coating

Clear glass allows large amounts of radiant energy to pass through--heat in from the sun in summer, heat out from your house in winter. A low-E, or low emissivity, coating is a microscopically thin metallic film that acts something like a two-way mirror, reflecting heat back into the house in winter and blocking heat from the sun in summer. Which it does better depends on how the coating is applied. The windows can be fine-tuned for different climates, producing Southern or Northern windows, for example.

Gas filled

Instead of air in the sealed space between glass panes, these windows use argon, krypton, or other inert gas. These gases are denser than air, so they provide better insulation.

• Full screen is standard, allowing full ventilation with both sashes open.
• Consider optional Full Solar Screen for added protection against solar heat gain.
• Heavy-duty commercial rating for long-term durability and strength
• Very tight double-hung design exceeds tough ANSI/AAMA 101-85 standards.
• Strong sash lock system for added security
• 3¼” deep frame and sash feature heavy-gauge walls about 20% thicker than most “builder grade” residential windows
• Glazed with full perimeter marine glazing boot that protects and further insulates the glass seated inside the sash frame
• Patented tip-to-tip weather stripping seals the sash in place for double protection against blowing wind, dirt, dust, and noise
