Helifix (Leviat)
BowTie is a long stainless steel tie that stabilises bulging walls by securing them into the ends of internal floor joists, with no external pattress plates. The BowTie HD is a heavy duty 12 mm diameter threaded bar with a self-cutting end, used where the wall must be tied back to internal floor joists or roof beams running parallel to it. Self-tapping so timbers do not split, suitable for hardwood, and installed from outside. Kit components: clearance-hole drill bit, BowTies, power support tool, HD Driver, hand support tool, and PolyPlus resin cartridge with extension nozzles and applicator.

Helifix (Leviat)
Kit contents: 10 x 1 m lengths of 6 mm HeliBar, one 3 litre tub of HeliBond cementitious grout, mortar chisel and rake, mixing paddle, and an applicator with nozzle. A 3-jaw-chuck power drill is needed but not supplied. Dimensions that matter: slots are cut into the horizontal mortar beds a minimum of 500 mm either side of the crack, and are 10 mm wide as standard to take the 6 mm HeliBar, with 4.5 mm HeliBar used for thin joints. Where two or more cracks are close together one continuous bar is used, long enough to extend 500 mm beyond the outer cracks, so three cracks at 250 mm apart need a 1.5 m bar. Slots are prepared with HeliPrimer WB or thoroughly wetted, HeliBond is the recommended bonding agent, and PolyPlus resin is used for small jobs or where load is applied quickly. Suitable for listed and historic structures and lime mortar.

Helifix (Leviat)
HeliBar is austenitic stainless steel helical reinforcing bar. It starts as round wire with a typical 0.2% proof stress of 500 N/mm2; the cold forming process that creates the helical hi-fin profile more than doubles that to around 1100 N/mm2. Bars are bonded into cut slots with HeliBond thixotropic cementitious grout, the composite action being the basis of the Helibeam System. Short 1 m lengths are used singly for crack stitching; longer lengths are used in pairs to form masonry beams that redistribute loads from foundation movement, and to create or reinstate failed lintels. Using 400 mm bars bonded at one end only, with the free end in a bonded sleeve, forms a movement joint. Applications listed include crack stitching, lintel repair, deep masonry beams, horizontal restraint with BowTie, reconnecting separated walls, securing parapets and supporting masonry over new openings.

Knauf
Manufacturer product data for 12.5mm moisture resistant plasterboard. Sheets are 1200mm wide at 2400mm (27.36 kg), 2700mm (30.78 kg) and 3000mm (34.2 kg). Comparing directly with the same maker's standard 12.5mm wallboard at 24.333 kg for a 2400mm sheet, the moisture panel is about 12 per cent heavier for identical dimensions, the additional mass being the water repellent additive in the core. There is no small format sheet in this range, so every board is a two person lift.

Knauf
Manufacturer product data for 12.5mm high density acoustic plasterboard. Sheets are 1200mm wide at 2400mm (33.12 kg), 2700mm (37.26 kg) and 3000mm (41.4 kg), which works out at about 11.5 kg per m2. Set against the same maker's standard 12.5mm wallboard at 24.333 kg for an identical 1200 x 2400mm sheet, the acoustic board is 36 per cent heavier, and that added mass is the entire acoustic mechanism. It is also 8.8 kg heavier per sheet, which is what makes a soundproofing upgrade physically harder work than a plain reboard.
- supplier figure RN-65PLTP
Knauf
Manufacturer product data for Knauf Soundshield Plus 15mm high density acoustic plasterboard. Boards are 1200mm wide and 15mm thick, supplied at 2400mm, 2700mm and 3000mm lengths weighing 38.304 kg, 43.092 kg and 47.88 kg per board respectively. That works out at roughly 13.3 kg per m2, about a third heavier than standard 12.5mm wallboard, which is the whole point of the board and also the reason a 2.4m sheet is a two person lift. Knauf states that as part of a full Knauf system the 15mm board contributes up to 54 dB Rw sound reduction and up to 120 minutes fire protection, and carries a severe duty impact rating.

Knauf
Manufacturer product data for standard 12.5mm plasterboard. Sheets are 1200mm wide at 2400mm (24.333 kg), 2500mm (23.7 kg), 2700mm (29.16 kg) and 3000mm (28.44 kg and 29.52 kg on the variants), plus a small 900 x 1800mm sheet at 12.8 kg. The 900 x 1800mm sheet at 12.8 kg is the one that matters for a domestic job because a single person can carry it up a staircase, while a 1200 x 2400mm sheet at over 24 kg needs two. The board is stated as suited to receive a plaster, a ready-mixed finish or direct decoration.

Knauf
Manufacturer product data for 9.5mm standard plasterboard, the thinner board normally used on ceilings and for overboarding. Sheets are 1200 x 1800mm at 17.856 kg and 1200 x 2400mm, with a 900mm wide sheet at 10.044 kg. Comparing with the same maker's 12.5mm wallboard at 24.333 kg for a 1200 x 2400mm sheet, the 9.5mm board is meaningfully lighter, which is why it is the ceiling board, but it also has less fire and acoustic mass and needs closer joist centres to avoid sagging.

Knauf
Manufacturer product data for standard plasterboard with an integral vapour control layer, the board used on the warm side of an insulated wall or roof to stop moisture reaching the cold structure. Sheets are 1200mm wide at 2400mm (22.75 kg), 2438mm (23.11 kg) and 2700mm (25.6 kg), plus a 900 x 1800mm sheet at 12.8 kg. It is lighter than the same maker's plain 12.5mm wallboard at 2400mm (24.333 kg), so the vapour layer adds no meaningful weight and the choice is purely about the wall build-up.
