Tools Required To Install Solid Roof All


All fixings supplied with roof kit. NB Fixings to house wall not supplied.

IMPORTANT: It is the installer’s responsibility to make sure the correct access safety equipmentis used during the installation of the lcotherm Solid Roof, such as access ladders and scaffolding


Setting the Eaves Beam




Fit the eaves to the top of the frames so the inside edge of the eaves is flush with the inside edge of the frame. Use M5 x 90professional wood screws, fixing throughthe frame and into the eaves beamat MAX 500mm centres & MAX 150mm in from the ends of a single eaves.
Where eaves beamsare longer than 5.3 Mtr,they must be jointed at 45degrees (pre cut in the factory)and fixed to the frame either side of the joint, 100mm apart.

Eaves Beam Dovetail Fixing



Eaves beam to be dovetail screwed one very corner using M5 x 90mm professional wood screws supplied, 3 through one face and 2 through the opposite face 25mmfrom the external corner.Same fixing detail applies for 135°, 110° etc.

Wall Plate To Wal Fixing Detail




Concrete fixingsthrough the wallplate 100mm infrom either sideand a max of 500mm centres.

IMPORTANT:Pack wallplate wherenecessary.

Once the eaves beam and wallplate have been fitted, follow this recommended pod assembly sequence for each pod before moving on to the next..

Edwardian Roof Style Pod Assembly Sequence


Once the eaves beam has been fitted follow the recommendedpod assembly sequence below before moving on to the next pod.





Victorian Roof Style Pod Assembly Sequence


Once the eaves beam has been fitted follow the recommended pod assembly sequence below using all the bolts and screws supplied for each pod before moving on to the next pod.

Pod Abutment Fixing Detail





Roof SizeStaggeredScrew Centres
4.9M x 5.3M250mm
5.4M x 6.4M170mm

Screws should be staggered from one side to another through all joining pod rafters, hips & valleys. Maximum dimensions of 4.8M x 6.4M for Victorian style roofs.


Wall Abutment Fixing Detail




Ridge section to be propped at the height given on the drawing provided in box pick bag before offering up the firstpod. Offer up the pod at the ridge and screw through

Concrete fixings through the end rafter of the first pod, 100mm up from the bottom, 150mm from the top and a maxof 500mm centres.

IMPORTANT: only fix to the house wall after all the pods are up and fixed together..

Breather Membrane Application


  1. Lay the first layer of Breather Membraneleaving no less than 100mm overhang aroundthe edges and no less than 100mm up theabutment wall and staple to the roof.
  2. Lay the second layer in the same way,overlapping the first layer and/or ridge no lessthan 150mm, staple in position.
  3. Repeat until roof is covered, making sure thatthe layer above is always overlapping the layerbelow to allow any water/moisture to run downand over the membrane and off the roof.
  4. There is no need to double up the BreatherMembrane on the hips as this could reduce theperformance of the roof.
  5. If Icotile is being used then the drainage matmust be put over the breather in a similar waybut does not need overlapping and can bepieced together.

Ridges & Hips






  1. .Lay Breather Membrane over theridge / hip by no less than 150mm.

  2. Tile to be cut level with the top ofthe plywood roof board.


Valleys (with valley tray)






  1. .Lay Breather Membrane running in and out of the valleyoverlapping by no less than 150mm where necessary

  2. Fit the valley tray over the Breather Membraneand overlap the valley trays by no less than150mm if needed. Valley tray to be fixed inposition on the outer most edges.

  3. .Ensure the tile is no less than 100mmover the valley tray.

Abutments






  1. . Turn Breather Membrane up against abutmentwall by no less than 100mm.

  2. Fit drainage channel over the Breather.

  3. .Membrane trapping it between the roof boardand abutment wall.

  4. Tile over the drainage channel being careful not toscrew through it.
  5. Fix lead flashing Code 4 or 5, in accordance with currentCodes of Practice & manufacturers recommendations

Steel Boomerang






  1. . Offer up the welded steel boomerang so it is centralto the pod rafter.

  2. . Hold in position and screw in place through the predrilled 5mm holes.

  3. .Drill through the 13mm pre drilled holes and throughthe rafter the steel is screwed too.

  4. . Fit the next pod so it is tight up to the steel and screwin position at the eaves.

  5. . Drill through the 13mm holes so you can bolt throughthe pods, sandwiching the steel between the pods

Insulation




IMPORTANT: All EPS boardshould be tight. Anygaps to be filled withfoam, being careful notto overfill and obstructthe ventilation gap.

Void must not be obstructed.

Lean-to Vented Ridge Finishing Detail




Solid Hips



Once the rectangles are up and bolted in position you must fit HP1 on both sidesbefore you fit the solid hip. This will give you the correct position to set the solidhips. Tack both to pod HP1 with 5 x 70mm screws supplied, screw top and bottomas indicated below. Install the remaining pods in this order - HP2, HP3 & HP4. Onceall the pods are in place you can bolt through the entire hip assembly with theM10 X 130mm bolts supplied.



Icoview Pod Fitting Detail



The Icoview pod comes fully built with the glazing bars fitted (unglazed). Fit the pod so thattop of the IcoView timber rafter is exactly 32mm from the top of the adjacent standard pod’sbare OSB. This will ensure that the tiles run in line with the finishing top cap when complete.



Icoview Ridge Support Bar



Position the Icoview ridge support bar under the Icotile / Icoslate ridge cap, in line with the edge.Clean the glass where the bar will be bonded to it, remove the cover tape and fix to the glass.Remove the top strip to affix to the ridge.


Note: the support bar is supplied oversized. Cut to fit between the aluminium top caps.


Glazing

Fit the glass so that the end of the double glazed unit (with the widest blacked out area)is at the bottom. Wet the gasket and slide the glass unit into place, temporarily fit therafter glass stops.
gasket pressure bar in place over the channel and glass, with the V guide locating intothe rafter bar V slot (see diagram).
Screw the metal spreader plates where the holes are in the pressure bar, using a lowtorque setting on your driver to avoid over tightening and distort the gasket on the glass.
Knock the powder coated top caps down and remove the rafter glass stops so you canbegin tiling.

Tiling

Start from the IcoView pod top caps outwards. The tiles should be set approximately 3mm awayfrom your top cap to allow water to trickle into the drain channel. The tiles should overhang at theeaves to be inline with the end of the rafter bar.
Once the area around the front of the Icoview pod is tiled re-fit the rafter glass stop which caps theend of the tile as well as the glass.

Ridge Caps

Ridge caps are fitted in exactly the same way as a standard Icotherm roof, with the additionof 2 strips of compriband at the top of the glass unit, above the blacked- out glass.
This weatherproofs the gap between the glass and the underside of the tile or tile batton.
Note: Dual Icoview pods come fully built with an engineered timber tosupport the central glazing bar and is fitted in exactly the same way.
