FIXING INSTRUCTIONS

HOW TO INSTALL COROTHERM AS A LEAN-TO ROOF

Sheet PreparationOnce the glazing bar spacing has been calculated,

according to the sheet thickness and means of support,

it may be necessary to cut sheets to size.

Corotherm can be cut

very easily and will not

crack or shatter. When

cutting parallel to the

flutes a sharp knife can

be used but when

cutting across the flutes a fine toothed saw is

required. For cutting curves, use a fine toothed

jigsaw. Cutting dust may be removed by vacuum.

If any dust is held in the flutes by static,

simply leave the sheet until the static charge

dissipates, then vacuum. Fix sealing tape at the

top end of each piece of Corotherm and

perforated breathing tape at the bottom.

In order to provide weather protection at the top

of the slope, rake out the mortar joint immediately

above the point at which the sheeting will meet the

wall - this will be used for the top edge of a length

of Ariel Aluminium or Butyl Flashing.

Glazing Bar PreparationRafter or Purlin Supported System - Carefully

insert the bottom seals to avoid stretching. Working

from one end press into place.

Ariel Rafter Supported Glazing Bar - Screw the

bottom half of the glazing bar to the rafter at

approximately 400mm centres

Ariel Purlin Supported Bar - Screw the bottom

half of the glazing bar to every purlin ensuring

the purlin spacing is not greater than 1500mm.

Use screws of suitable length usually half the

depth of the support being used. Screws should

be sealed in waterproof mastic, striking off any

surplus after driving the screws.

Self Supporting System - Refer to the detailed

fitting instructions supplied with the glazing

bar components.

Flashing PreparationBegin installation at one flank of the slope, by

preparing a length of side flashing. The apron of

the side flashing should be pre-drilled to accept

screw fixings and these holes should be 3mm

oversize, to allow expansion and contraction of the

flashing. In situations where the sheeting is to be

installed abutting an end wall, the side flashing may

be inverted so that the apron forms an upstand

and finished using Ariel Aluminium or Butyl Flashing,

stepped into the brickwork coursing.

InstallationPeel back the protective film from the edges of the

first prepared sheet, ensuring that the sealing tape

will be at the top of the slope and the perforated

breathing tape is to the bottom of the slope. Run

a bead of clear low-modulus silicone sealant into

the prepared side flashing and push the sheet into

position with the

printed film

uppermost. At least

one vertical rib of each

Corotherm sheet

should engage within

the glazing bar. Attach the side flashing to the

side of the roof, then check the important 3mm

expansion clearance at the side of the sheet

and a 10mm

expansion gap at the

top of the slope.

Begin to install the

flashing at this stage,

carefully following

the fixing instructions. Lay the second sheet in

position then, starting at the downslope end, line

up the ends of the cap and base and tap home

with a rubber mallet, or woodblock and hammer

until the edge seals have flattened against the

sheet. Corotherm glazing bar caps have co-extruded

integral sealing strips for permanent weather

protection. Over driving the glazing bar cap may

cause noise from the sheets as they expand and

contract with temperature changes. Continue

laying sheets and glazing bar caps in this manner

until reaching the final sheet. Before installing this

sheet press the second side flashing into place,

using clear low-modulus

silicone sealant as before.

Installation (cont.)Lay the final sheet with side flashing attached and

secure the flashing apron to the wall. Fit the final

glazing bar cap and complete the run of flashing.

Finally, remove all

protective film.

To protect the breather

tape which allows

ventilation of the sheet,

fit end caps at the lower

end of the sheeting, with the rainwater drip

downwards to lead run-off water into the gutter.

Run a bead of sealant along the top edge of the

end cap to prevent water ingress.

Note: All Corotherm sheets must have an

expansion allowance of 3mm around all fixings

and 3mm/metre for both the length and the width

of the sheet. Mechanical fixing at the lower end

of the sheet using a centrally positioned fixing

button is recommended to prevent any downslope

migration of the sheet.

CleaningCorotherm can be easily and quickly washed with

luke warm soapy water and a soft cloth or sponge.

Do not use brushes or sharp objects and avoid any

abrasives or cleaners of a high alkaline nature.

HOW TO FIX
