Door Frame Kits

Double Glazed Doors


Our door frames are made from aluminium with traditional and slimline options.

When choosing an aluminium internal door frame, you want one that is cost-effective, quick to install, and in keeping with the build's aesthetic.



Innovative Design

Our frames are competitively priced whilst being custom machined to your exact requirements. Our innovative double glazed door frame design allows you to glaze straight out of the back of the frame, which reduces the need for additional aluminium extrusions and enables you to save time during installation.

In addition to our standard double glazed door frame kits, we also offer a new version with a deeper glazing pocket of 17mm, allowing for more of the glass to be held by the frame and increasing stability all round. All of our double glazed door frame kits come complete with all the items you might need to install. These include strike plates, shoulder brackets, floor brackets and acoustic gasket.



Custom Fabrication

We supply custom-fabricated frames with hinge slots CNC machined with screw holes pre-tapped, ready to install hinges and slots for the strike plates to allow them to sit flush with the frame. As with all of our other sections, we hold the aluminium extrusion for our double glazed doors in stock in 4 standard colours, Grey RAL9006, White RAL9010, Black RAL9005 and Anthracite Grey RAL7016. We also maintain a stock of mill finish material, enabling us to custom paint the frames to any colour you could want or even anodize them for that exceptional finish.
