Nice to see that Jazzman is not alone in installing reflective foil. Some posters in the past have been very skeptical about its performance.
Nice also to see someone else also using the screw type battens. Did you have any problems getting your workers to accept this? (probably best to quote and answer this in the
Roof forum).
We saw the same picture glass blocks too. We were very tempted, but decided that too many embellishments like this might break the bank

HomePro wasn't it? We did however settle for a set of the Lime-Lite blocks which we embedded in the walls in various places around the house (pics will be added to Jazzman's album later today - watch this space). We used a lot of green glass blocks to decorates to front and rear patio doors and windows.
