The 60 mm figure is the overall glazing capacity for this product. It is separate from the frame depth and individual pane thickness. We confirm a compatible glass build-up for the dimensions, hardware and performance you need.
Start with your preferred overall frame dimensions. We check the proposed design against sash weight, hardware, wind load, glass and installation requirements before final dimensions and fabrication drawings are agreed.
Your quotation itemises the supplied specification and any agreed survey, delivery and installation. The optional rate you enter in the planner is for your own budget calculation; we provide the confirmed selling price in your quotation.
