Recommended technical guidance

Liniar PVCU window and door manufacturers can achieve the highest levels of quality and reliable long-term performance in every finished product by following the latest fastener guidance from Rapierstar, the company has reported.

Rapierstar has published three recommended fixings manuals (RFMs), which provide detailed guidance on which fasteners to use in all aspects of Liniar window and door assembly, including bifold doors. All three are free to download in the Info Point at

One comprehensive RFM provides fastener guidance for the manufacture of the majority of Liniar windows – casements, flush sashes, fully reversible and tilt and turns – plus French doors/windows and bay windows. Each different element of the window or door is covered in detail, from attaching hardware to Liniar outerframes to baypole fixing, with diagrams indicating the correct fastener to use in coated carbon steel and stainless steel, plus product codes for easy ordering.

Two additional RFMs provide advice on fastener use for manufacturing Liniar bifolding doors. These cover the standard Liniar bifolding door and its ModLok bifold system, which meets the security requirements of PAS24.

Mark Calpin, technical consultant at Rapierstar, said: “By ensuring the correct fasteners are used throughout Liniar window and door assembly, fabricators can get the best results every time with these technically innovative profiles. That’s why our RFMs can play an important role, complementing the industry leading technical support Liniar already provides.”

Rapierstar also offers a range of resources on its website, including technical datasheets for all products, information on testing, and other documentation. Bespoke practical assistance can also be provided, such as signage and labelling for workstations along the fabrication line to reduce the risk of the wrong fasteners being used in error.
