Glazing capacity is up to 42 mm overall. We check the glass build-up, safety treatment and any solar-control or acoustic requirements for your assembly. Your quotation confirms the RAL colour and finish; specify one colour for both faces.
Choose the right glazing ↗Reference Ud: 1.17 W/m²K for a 1100 × 2100 mm door with Ultimate frame and a threshold, using glazing with Ug 0.5 W/m²K. This figure applies to that reference assembly. We confirm the complete door performance for your agreed dimensions and specification.
Understand whole-assembly performance ↗Bring us your opening sizes, drawings and priorities. We help you develop the specification and agree the supply, survey and installation scope before you commit.
The 42 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.
