Ultra Plus Window System
WHAT MAKES WEATHERTITE ULTRAPLUS™ WINDOWS BETTER?
Shop and compare. We think you will see why WeatherTite Windows are one of the best investments for your home. Technology, engineering, craftsmanship, robotic precision manufacturing and people who care about every single window we make means that we will manufacture only the best for you.
We reinforce the sash keeper rail in our double hung and slider windows with a unique resin-based glassfilled composite material. K-Beam™ utilizes Kevlar® fibers for additional strength and the lowest thermal conductivity meaning extra energy efficiency. Most manufacturers of vinyl windows today use aluminum or steel to reinforce their vinyl, which works like a thermal short circuit due to the poor thermal properties of the metal. K-Beam™, our advanced composite reinforcement with Kevlar®, assures maximum strength, energy efficiency and durability “FOR THE LIFE OF YOUR HOUSE®”.
The WeatherTite Ultra Plus Window System features the “Super Spacer” in the R-4, R-7, and R-10 window series. Super Spacer® is the world’s only 100% foam, metal free, warm edge spacer. Most other spacers contain metal which readily transfers cold and heat. Super Spacer provides exceptional insulating qualities and reduction in condensation build-up.

INSULATED GLASS PACKAGES
Our technologically-advanced, robotically manufactured insulated glass packages offer a choice of insulating performance which can be tailored to your geographic location. The finest in multiple layered glass and argon or krypton insulating gas, along with super energy efficient “warm edge” sealing technology, assure maximum energy savings and resistance to condensation.
UPVC FRAMES AND SASHES
All of our windows are made using the finest quality, specially blended, un-plasticized poly vinyl chloride, or uPVC, frames and sash. Your window frame and sash material will never rot like wood windows are prone to do; it will never corrode like metal windows. uPVC is good for the environment because it saves energy better than other materials. It never needs refinishing (no need to use environmentally harsh varnishes or stains) and it lasts much, much longer than wood or other materials. This inherent durability means that the likelihood of having to replace your uPVC windows again in the future is much less than if you used wood or metal. It is also important that you choose WELDED vinyl windows because the corners are permanently fused together and will never separate. Many vinyl windows today are screwed or stapled at the corners just like wood or metal windows. Some are welded on very old, single- or doubleweld machines. The corners can separate and leak air and water. Choose only fusion welded vinyl produced with robotic 4-point welding equipment.
The WeatherTite Ultra Plus Window System has a great impact on maintaining an optimum health environment in your home. Condensation contributes to the growth of mold, which, more and more is being linked to child asthma, plus increases in general respiratory illnesses, allergies and outbreaks of fungal diseases.
This mold can be hidden from sight deep within the window and wall openings and the Ultra Plus windows utilizing the “Super Spacer” System.
ULTRASMART™ WEATHERSTRIPPING
600 inches of UltraSmart™ weatherstripping is used in an average sized double hung window. UltraSmart is made of Ultrafab® Tri-Fin® Gold Series weather stripping with built-in Ultra-Fresh® antimicrobial protection which minimizes drafts, dust, and pollen. It also fights the growth of mold on the weatherstripping material.

UltraSmart weatherstripping resists and kills allergy
aggravating micro-particles such as pollen, bacteria, mold and dust.
AUTO-MAJIK™ LOCK
An optional automatic lock feature, Auto-Majik™, ensures that whenever you close the sash of your window, the lock automatically engages leaving you with peace of mind regarding security and safety. You’ll never “forget” to lock your windows again.
