The Brennan Traditions Horizontal Sliding windows are known as a dual-lite slider in which both sashes of the window are able to vent. Sliders are designed for lots of light and ventilation and are popular in craftsman style homes.
This is a great window style to use near walkways because they don't tilt outward and you'll get more light and ventilation than with a standard hung window.
Traditions windows are made with durable and energy efficient vinyl material and feature high-performance insulated glass. Our windows are made to fit your home so you can feel confident that you'll get a beautiful product and feel comfortable inside your home for years to come.
A. FLIPLOCK automatic locks that meet or exceed forced entry resistance requirements.
B. Gliding system provides an easy and quiet operation.
C. Our super clear, BetterVue Screen is standard on this window.
• DP30 Performance rating.
When you select a Vivid Color™ option you're choosing:
NT's coatings are water-based and EPA compliant, ensuring that they will maintain their integrity with limited environmental impact–keeping you and your family safe from unnecessary chemicals.
You can count on Vivid Colors for a safe and high-performance finish.
Our BetterVue screens are so clear that they almost look invisible. This means that the BetterVue screen itself is not clearly visible in ones view from a distance. In fact, you’ll find that you only notice the screen as you get close to it – a feature designed to ensure that your guests won’t walk into the screen but clear enough to give you unobstructed, perfect views all the time.
And not only is the BetterVue screen system a perfect screen for anyone wanting to enjoy the best view of the outdoors, but the screen is also flame retardant, and by design the BetterVue screen system allows more airflow into your home while still protecting against those pesky pests.
Engineered for the Extreme Heat
Designed to function as a reflective thermos, the Unix Glass system keeps the temperature in your home more comfortable and consistent. Say goodbye to out of control temperature swings and hello to the level of comfort you have been waiting for.
The all-foam formula of Super Spacer blocks the heat path, so homes stay cool and comfortable inside.
The dual seal system helps Super Spacer insulating glass units last up to five times longer in durability tests than single-seal units.
The all-foam formula offsets the effects of temperature changes, baromatic pressure, window load, and glazing pressure. The end result is less seal failure and fewer stress cracks.
Installing ENERGY STAR® qualified windows lowers energy bills and saves you money over single-pane and even new double-paned, clear-glass windows. Windows with our high-performance glass package are ENERGY STAR® qualified for all regions.
