Every fixing through the membrane is a deliberate hole in the only thing keeping water out, and on an EPDM, TPO or single-ply roof it also tends to void the waterproofing warranty that made the roof worth paying for. Yet the pipework, ducting and condensing units still have to go somewhere.\u003c\/p\u003e\n\n\u003cp\u003eBallasted support frames solve it by sitting on the roof rather than through it. Each frame is a pair of uprights and a cross-member in 41mm slotted strut channel, bolted into two heavy recycled-rubber feet that spread the weight across the membrane and grip without adhesive or fixings. Nothing is drilled, nothing is sealed, and the whole run can be lifted and repositioned when the plant layout changes.\u003c\/p\u003e\n\n\u003ch3\u003eWhat it carries\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInsulated pipe runs, condensate lines and refrigerant pipework\u003c\/li\u003e\n\u003cli\u003eCable tray, basket and conduit containment\u003c\/li\u003e\n\u003cli\u003eRectangular and spiral ductwork\u003c\/li\u003e\n\u003cli\u003eSmall condensing units and ancillary plant on cross-bearers\u003c\/li\u003e\n\u003cli\u003eSolar cable management and inverter mounting on flat roofs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame type\u003c\/th\u003e\n\u003ctd\u003eH-frame: two uprights, one cross-member, fully adjustable on the slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eChannel\u003c\/th\u003e\n\u003ctd\u003e41mm slotted strut channel, hot dip galvanised\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFeet\u003c\/th\u003e\n\u003ctd\u003eTwo heavy-duty recycled rubber feet per frame, 350 x 350 x 95mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFixings included\u003c\/th\u003e\n\u003ctd\u003eTwo galvanised angle brackets, eight M10 bolts, eight M10 channel nuts per frame\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame heights\u003c\/th\u003e\n\u003ctd\u003e500mm, 750mm or 1000mm channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePack sizes\u003c\/th\u003e\n\u003ctd\u003e4 frames or 8 frames\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFixing method\u003c\/th\u003e\n\u003ctd\u003eFree-standing and ballasted.

As a working rule, service pipework on a flat roof is usually supported at 1.5m to 2m centres, so a 12m run needs seven or eight frames rather than four. Order the pack that covers the run with a frame at each change of direction and either side of any valve or joint, and follow the pipework manufacturer's own support centres where they are specified.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently asked\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWill the rubber feet damage an EPDM or single-ply membrane?\u003c\/strong\u003e\u003cbr\u003eThe feet are designed to bear on a roof covering and spread the load rather than concentrate it. On a new or soft membrane, or over insulation with limited compressive strength, set them on protection pads. Our \u003ca href=\"https:\/\/rubberroofuk.uk\/products\/walkway-pads\"\u003eEPDM rubber walkway pads\u003c\/a\u003e work well underneath the feet.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow does it stay put in high wind?\u003c\/strong\u003e\u003cbr\u003eThe frames rely on the weight of the frame plus the services they carry. On exposed or high-rise roofs, or where the run carries little weight, add ballast or tie the run into adjacent plant. Do not assume a lightly loaded frame will hold on an exposed parapet-free roof.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I adjust the height after assembly?\u003c\/strong\u003e\u003cbr\u003eYes. The uprights are slotted along their length, so the cross-member can be repositioned with a spanner. That is also how you level a run across a roof with a fall in it.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need different frames for a roof with a fall?\u003c\/strong\u003e\u003cbr\u003eNo. Use the same frames and set each cross-member at its own height to keep the pipe run level. This is the main practical reason to choose the 750mm or 1000mm channel over the 500mm.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat about the roof underneath?\u003c\/strong\u003e\u003cbr\u003eIf the covering is coming to the end of its life, deal with that first.
