Style, safety and flexible designs are the cornerstones of the WeatherMaster Vertical Window System. Made in four colors and specifically designed for porches, screen enclosures or even gazebos, the WeatherMaster system is easily installed and can convert any of these areas into your favourite three season room in the house.

The guide tracks allow smooth operation, opening  each window up or down for up to 70% ventilation. These maintenance free units are all custom made to fit your openings exactly and come with a 10 year warranty against factory defect.


Window System Features

The WeatherMaster vertical 4 track window closes to  reduce wind, rain, pollen & sound. The units move effortlessly, stacking up or down to allow a generous 70% ventilation opening.




Enclosures are an economical way to expand the usefulness of your recreational areas. The WeatherMaster Window combines the open feeling of a screen room and the comfort and convenience of a patio room. With the WeatherMaster window you get the safety of tempered glass and the convenience of tint at no extra charge.


Measuring instructions: Start at the left side of screened area and mark #1, #2, etc. on the porch framing. Your windows will be shipped to you numbered as you order them. Measure smallest daylight opening size, width and height in at least two places. Allow for corner and floor to accommodate 1 1/8" exterior flange and a 1 7/8" recess into the opening.


Taking care of your vinyl glazed windows is easy, first remove dust or grit with a soft cloth or brush. Then we recommend our Sunspace Vinyl Cleaner and buff with a soft cloth. Do not use harsh detergents or formulas containing bleach. Do not use professional pressure cleaners.


WeatherMaster stereo units are available up to 96" high and 144" wide. The stereo unit uses the same design as the smaller 4 vent unit except the main frame is divided into 2 or 3 openings, each with 4 vents. This feature gives the stereo units 8 vent or 12 vent configurations and reduces the need for additional framing and extra cost.
