Leinfelden-Echterdingen – Around a year ago, Roto Frank Fenster- und Türtechnologie GmbH (Roto FTT) launched an attractive new range of butt hinges for PVC entrance doors. This line now includes butt hinges for entrance doors made from timber or aluminium profiles with a 16 mm Euro-groove. The product range has also been expanded by the addition of a new cover cap with long legs for doors with a fixed side section on the hinge side. This is an option for putting the finishing touches to the incredibly slimline design of the hinges, as it completely conceals the mechanics.
Positive feedback from the market
Over the past few months, manufacturers around the world have been impressed by the design and functionality of the numerous “Roto Solid B” hinge versions for PVC main doors. Frederik Zink, managing partner of TH.ZINK GmbH Fenster und Türen in the German town of Bergen, explains: “The new ‘Roto Solid B’ butt hinge is suitable for doors with panels which cover the leaf as well as for doors with recessed panels, making it incredibly versatile. This is a huge benefit for us, as it reduces the variety of different versions in storage and production logistics. The slimline shape of the hinge makes it an ideal fit for modern door designs. It’s also good that ‘Solid B’ is suitable for high loads. The door hinge can be adjusted using just one tool. This obviously saves time during installation.”
Wulfran Fuzeaux, one of the managing directors at manufacturer 2MA2P in the French city of Saint-Nazaire, is also pleased: “We were truly impressed by the large adjustment ranges and the slimline hinge design of ‘Roto Solid B’. Both aspects have been noticeably improved compared to the previous model, ‘150 R’. The new butt hinge is an excellent fit for our premium aluminium doors, especially those with decorative glass panels.”
Slimline appearance without offset outlines
All versions in the “Solid B” range share technical and aesthetic features with added value. For instance, no gaps are formed between the leaf hinge and frame hinge when adjusting the door because the adjustment mechanisms are integrated in the hinge roller. Offset outlines are prevented. The slimline appearance is retained. This is the case for the two- and three-part butt hinges and regardless of whether a version for rebate- or overlap-screwed installation with a diameter of 18 or 22 mm is selected.
Adjustments without the need for unhinging
The continuous height, lateral and gasket compression adjustment can be achieved without unhinging the door, while the results can be visually inspected straight away. Linear 3D adjustment makes precise adaptation of the leaf in the frame particularly simple. All adjustments are easy to make with a size 4 hex key.
Uniform design for all leaves
The uniform design of all hinges and the extensive range of products open up the option to tailor the appearance of PVC, timber or aluminium doors with different weights to a property. Depending on the butt hinge version selected, the number of hinges and the properties of the chosen door profile, sash weights of up to 80 kg, 120 kg or 160 kg are possible. Manufacturers use the “222 P” and “322 P” butt hinges plus a hinge retaining mechanism to produce doors with increased burglary protection. They are compatible with RC 2. The test in accordance with SKG** is in the preparation stage.
The corrosion protection of the butt hinges conforms to DIN EN 1670 class 5, therefore meeting the most stringent requirements. The 200,000 opening cycles achieved in accordance with DIN EN 1935 and DIN EN 1191 confirm the reliable durability of the door hinges.
