The quality of a waterproof seal of any professional roofers in Australia can never be better than the tools with which these seals are made. The Leister ST has been considered as the workhorse of the industry in terms of welding thermoplastics with its strong design and practical simplicity. But the equipment is half the battle, to attain an ideal weld on TPO or PVC membranes, you will have to fit your hot air tool with the right attachments.
A heating element is not the only part of creating a versatile roofing kit. When choosing the appropriate nozzles, you can be certain that your Leister ST would cope with long straight seams, as well as with complex corner work.
1. Wide-Slot Nozzle Standard 40mm
The widest nozzle 40mm wide nozzle is the most important part of any roofing project. This is an item that is used to attach welding overlap seams on expansive flat areas. It, when combined with the Leister ST, gives a uniform spread of the hot air, which lets the membrane melt evenly. This would guarantee a structural connection, which can resist the severe heat of the Australian sun and heavy rainfall of seasons.
2. The 20mm Wide-Slot Nozzle of Detail Work
Although the bulk of the work is done by the 40mm version, the nozzle of 20mm is crucial in precision work. It is employed mostly in welding perimeter flashings and upstands and in tight angles where a larger nozzle would be cumbersome. The high flow of air enables control and eliminates scalding of the membrane in the restricted areas.
3. Angled Nozzles 90 and 60 Angels
Not all roofs consist of a flat surface. Angled nozzles would be essential when welding under low-hanging obstacles on a vertical surface or when welding low-end corners .
A kit does not have a nozzle, but to complete a kit, a silicone or brass pressure roller is required. They are applied in combination with the hot air tool to squeeze the heated layers against each other making sure that the bond between the molecules is airtight.
4. The Penny roller in Tight Corners
A typical roller may not get to the vertex when one has a complex internal or external corner. A small roller made of brass is a penny roller that enables the roofer to directly press on the smallest of details making sure that every centimetre of the roof is waterproof.
Summary
The construction of the final roofing kit presupposes an effective choice of accessories which will be able to support the power of the Leister ST. Having invested in a variety of high quality wide slots and angled nozzles, you have made your tool multi talented and able to work on any architectural problem. The outcome of any profession relies on professional equipment; make sure that your outfit is prepared for the next assignment.
