Light Transmission (LT) and Direct Solar Transmission (Direct ST) acc. EN410 as measured on 600mm x 600mm samples. Total Solar Transmission (Total ST) acc. EN410 is the total solar energy that enters the interior of a building. Solar Heat Gain Coefficient or g-value is the total solar energy the enters the interior of a building, divided by 100. Shading Coefficient or b-value is the ratio of the total solar energy that enters the interior of a building with a given material and the total solar energy that enters the interior of a building with a standard 3mm glass panel.

Key Dimensions & Features

Twinfix thermally broken aluminium frame profiles can be installed to allow fixing of Thermoclick Panels from either inside or outside the building. Ensure that the shorter leg of the frame faces the side from which you wish to install the panels. The frame has a `U' Value of 3.3W/m2K. Each profile has two possible locations for fixing screws (see dotted blue arrows above). It is also possible for fixing cleats to be pre-welded.

Length of Panels limited as intermediate rails are not possible. (See "S1" on page 2.)

Optional Sill

To ensure accurate alignment of the frame, Joint Plates are inserted between lengths of profile. Profiles to be mitred at corners. 5mm Diameter drainage holes to be drilled at approximately 500mm centres in outside face of Base Rail. When the frame has been completed, a bead of silicone sealant should be applied inside each Base Rail joint prior to installation of the panels. (Ensure it is compatible with polycarbonate.) A bead of sealant can also be applied where the aluminium frame meets the building at the top and sides.

VERTICAL SECTION THROUGH FRAME

PREPARE THERMOCLICK PANELS:

1. 2. 3. Cut Thermoclick panels to length using a fine toothed saw. (Internal vertical frame dimension + 40mm, or Overall frame height ­ 95mm). Blow dust and swarf out of the panels. The UV protected side of the panel is covered with printed masking and must face the outside of the building. The nonUV side is protected with clear masking. Prior to fixing masking should be pulled back from the edges and completely removed after installation. Do not cut it off with a knife. Panels are installed Left to Right with the `tongue' on the Right. Apply adhesive tapes to top and foot of panels: Impermeable tape to the top; Breather tape to the foot. Ensure that the tapes are well bonded to the panels along edges and corners.

Installing the Panels

NB Insert `E' Gasket (without stretching) into groove in aluminium frame and seal base rail joints before installing panels (see page 3). 1. Lift top of panel up into the top rail. Drop foot of panel into the base rail. Slide the panel fully into the side rail. `E' Gasket

Tongue Groove SECTION NB Check the overall frame width. It may be necessary for the first panel to be cut narrower to ensure that the last panel of the run is a suitable width ­ See dimension `X' below and next page.

4.

Install second panel as before and slide firmly until the groove has clicked onto the tongue of the first panel.

SECTION NB If there are intermediate support rails, Fix-Keys must be locked into the joint of each panel junction as the panels are installed. (See page 7 for details.)

NB Dimension `X' must be within the tolerances shown, i.e. 544mm to 950mm

Dimension `X' SECTION Greater than 544mm and Less than 950mm See also Page 6

Finishing a run of Panels

Dimension `X' (See Below)

The width of the last panel is calculated by: Dimension `X' + 50mm ­ 544mm Cut the last panel to the correct width. Blow, tape and install into frame following the sequence shown below.

Last Panel width

Panel not used

1. Install last panel into frame and push fully to the right into the side profile. 544m m Last Panel width

2. Install a full width panel into the gap. 3. Push the full panel to the right to lock into the cut panel.

Dimension `X'

50mm

4. Slide the two locked panels to the left until they lock onto the previous tongue.

Slide left

NB A flat tool e.g. a Bolster Chisel, can be inserted into the panel joint to assist sliding the joined panels.

NB When all the panels have been installed, a wedge gasket is inserted into the frame. (See page 7.)

INSTALLING WEDGE GASKET TO COMPLETE THE SYSTEM

To complete the Thermoclick system and secure the panels, a Wedge Gasket is inserted into all edges of the frame. Wetting the gasket with a mild mixture of water and washing-up liquid may assist insertion. Do not stretch the gasket when undertaking this task.
