Frameless Sliding Windows - Overlay vs Insert Slider - which one?
Aluminium frames are out, more glass is in! So which option of our frameless slider do you choose?
Overlay sliders provide a bigger opening because the frame sits outside the aperture/cut-out in your vessel, but they do require top and bottom rails of your aperture to be parallel, just like a framed slider.
A single-track frame is neatly tucked away outside the aperture, under your roof line, and we will work with you during the design process to get the biggest opening whilst giving a minimal appearance to the frame. The end result is a more glass, less, aluminium look to your window that will match your direct glazed front windscreens much more seamlessly.
Insert Sliders are for the more adventurous designs. They don't require the top and bottom of the aperture/cutout to be parallel, as we create a parallel frame within the fixed piece of glass.
We called them Insert Sliders because we take a larger direct fixed window, and we "insert" a sliding window into the middle of it.
They are more technical, and therefore more expensive than an Overlay Slider, but they allow more creativity in your vessel design.
Here are some photos of each type that we have supplied, from inside and outside views.
