Aluminium has a coefficient of expansion equal to 0.00002348mm per °C on average, this equates to just over 1.4mm per metre on a temperature range of -20°C to +40°C. Typically a 3mm to 4mm expansion gap between the ends of the gutter sections is advisable.
ARP recommend & supply Arbosil 1096 Low Modulus Silicone sealant and it is essential that this or a direct equivalent is used to seal the joints as this will ensure a strong mechanical bond that withstands the forces associated with thermal movement. It is important to observe the sealant manufacturers guidelines concerning application and curing during cold or damp weather conditions and that before assembling the joint all surfaces are clean and free from grease, acetone applied with a soft cloth and wiped dry is recommed.
Vintage O.G. gutters have loose internal union connectors that are snapped into position.Having sited the gutter apply 2 x 6mm beads of Arbosil 1096 Low Modulus Silicone sealant to each side of the joint (Fig 2).Carefully offer the union connector into position, clip the rear of the union into place first followed by the front edge, apply sealant to both sides of joint and tool in. Excess sealant should then be removed.
