The proof is in the product
- How sash components can be manually “upgraded” with the 150 kg version of the concealed hardware…
Before we get to grips with everything, here’s some productoriented core information provided by Roto, the selfproclaimed worldwide number one manufacturer of Tilt&Turn windows. According to them, even their most hard-wearing options exhibit the range’s general trademarks: concealed hinge sides and a comfortable window opening angle of up to 100°.
Maintenance-free load transfer devices
The 150 kg option is routinely offered with a tilt-restrictor and an anti-slam device. It is available for single- and double-sashed timber, PVC and aluminium
windows (with 16 mm hardware groove) in the versions Tilt&Turn, Turn-Only and Tilt-First. Extensive accessories from the “NT” modular system can therefore fulfil almost every customer wish. Roto emphasises that a T striker-entry in the tilt mechanism and anti-jemmy protection in the corner hinge ensures optimal functional security. Furthermore, this also offers a burglary resistance grade of up to RC 2/RC 2N according to DIN EN 1627-1630. As an extension to the “Designo” range, two further components complement the standard hardware. When installed over the pivot rest, these function as maintenance-free
load transfer devices with high sash weights. A preloaded spring pack in the sash directs the weight down the frame via a pivot rod and thus relieves the pivot rest. This prevents the lowering of heavy sashes. According to Roto, the necessary weight stability arises from the usage of extremely hard steel alloys. Furthermore, the extreme care during production with separately controlled processes is an important factor in quality control. Their 10-year warranty is based on this.
Practical theory
Apparently, the (one-person) installation does not require any specialist tools. This is also possible retrospectively, because
the parts can be slotted on to existing components of the pivot rest easily. Trimming is not needed, Roto adds. Threedimensional adjustment of the window sashes is still possible with adjusting screws, of course. This simplifies the adjustment in all situations and ensures permanent and smooth use. So far, so good. However, does this also work in the individual installation practise? Yes, is the simple conclusion of this specific example. According to the motto: Step by step to a professional result. www.roto-frank.com
IT ALL HINGES ON SPECIFICATION
Security has become a strong selling feature for installers, with much emphasis on high-security locks. However, as Ben Penson of ERA explains, choice of hinge has an equally important part to play in designing a doorset that will meet PAS 24 standards. A key requirement of a hinge is durability – bear in mind the number of opening and closing operations a pedestrian door will have to withstand compared to most windows – so strength should be a given. A hinge that cannot bear the weight of the door or handle the demands of traffic will, over time, begin to fail and result in costly call-outs. Additional service costs are the long-term effect of the wrong choice of hinge; the short-term effect could be failure to perform to current standards. Hinges are integral to the security of a doorset – but it is important to realise that security is not inherent in every hinge. The PAS 24 enhanced security test standard certifies that a door, frame, lock an B�&Gv&R6WB�2v�F�7F��B6W&�W2�b��6�6�FW7G2�&6VB��6������WF��G2�b'W&v�'��6�6���6R�b���vR�22���'F�B26���6R�b��6�����vR7V6�f�6F���6��6���7B��&�f�F&�ƗG��BV6R�b��7F��F����FV�F��rF��Vv��B֖v�B&RF�6�fR6�7B�6�VF��"���vR6�'&�fR�ƗFW&�ǒ�2&r�b&�G2�v��6�6�V�BF�RWF�FV�֖�WFW2F�76V�&�R&Vf�&R��R6�WfV�&Vv��F�f�B�BF�F�RF��"�F��2�V�F�ƖVB�fW"F�R�V�&W"�b��Vf7GW&VBF��'2v�����&RF���VvFRF�R�&�v���6�7B6f��r����vRƖ�RF�RU$V�F�����F�R�F�W"��B��2&W6V�FVB��&R�76V�&�VB6��6��&�6��rF�RF�&VR'G2�V�&Ɩ�rg&�R�B66�6�FR6����V�G2F�&Rf�GFVB6W&FVǒ�6f��rF��R��f'&�6F����F�RV�F���2FW6�v�VB7V6�f�6�ǒF��VWBF�R2#B6V7W&�G�7F�F&Bf�"d7RF��'2��ffW&��rf�W"67&Wr�'Bf��W2��F�F�R66�&V��f�&6��r6��&W"v��6�&�f�FW2�F��V�6V7W&�G��bF�RF��"6��W2V�FW"GF6����F�W"6V7W&�G�fVGW&R�2F�BF�R�F��ƖgBfVGW&R�2��ǒ66W76�&�Rv�V�F�RF��"�2��F�R�V��6�F���( 2��6R6��6VB�F�RF��"7F�26V7W&R�f�"��&R��f�&�F�����U$6���#"C�c�"f�6�Bwwr�W&�6V7W&�G��6���f�"w&�W���W6fR&�GV7G2�B6���W2�f�6�B�GG���wwr�w&�W���W6fR�6���ࠣc@��Tr#0��F�&VB��&R�f�6�Bwwr�6�V'f�Wr�V��6�Р��
