Thermo Twin | V700 Vinyl Double Hung Window

V700 Vinyl Double Hung Window Series


A concern for many homeowners is how their new windows will look. V700 Windows are designed with beauty in mind. This model comes equipped with a beveled exterior to add architectural complexity and aesthetic appeal.


V700 vinyl windows operate with superior functionality, made possible by the incorporation of moveable window sashes. These sash components are available in two configurations, standard non-equal lite and equal lite. These vinyl sashes operate by tilting inward for easy cleaning.


Quality windows are our guarantee at Thermo-Twin. That’s why V700 vinyl windows are expertly crafted to be strong and durable, as well as to accommodate various accessories. They also use composite reinforcement by Chelsea to ensure maximum strength.  In order to allow you to utilize window trim and attachments, each window incorporates subtle accessory grooves.


Clean, pristine glass really makes the windows in your home shine. V700 vinyl windows from Thermo-Twin are constructed with 7/8” insulated glass, secured into the sashes with silicone glazing. For the right look and feel, as well as to ensure superior weatherproofing, various glass packages are available for you to choose from to complement the V700 line.

Energy Efficiency

We know that you want to keep your home warm and safe from the elements. That’s why V700 windows are designed with energy efficiency in mind. Each window comes standard with a half screen (full screen available upon request). The V700 is also equipped with dual weather stripping at the stiles, interlock, head and sill. This feature ensures protection against air infiltration, increasing overall energy efficiency.
