AF24 Aluminium Panels - A Frame

The AF24 panels are a sturdy, aluminium profile framed panel that is mounted vertically on a sloped roof or flat area. Roofing systems for both slates and tiled roofs are available. With its low eight and optimized size this panel is easy to manoeuvre and quick to install. The AF24 panel weighs in at just 38 kg's (or a mere 15.33 kg's per m2), as a result this panel is easier to handle without lacking in any strength, rigidity or efficiency. 

The ultra efficient absorber combined with 50mm of rockwool insulation allows the panel to effectively utilise a large amount of the Sun's energy
