Another day; another quote.
Overall almost the same total cost but it is interesting that previously
"The Supplied and fitted cost for a 1 x 3 section SL20 Classic Minimal framed sliding door system with all panels sliding with multi point locking and all frames in a standard RAL colour all glazed units will be energy efficient glazing and a U-value of 1.3. The approximate size of the doors would be 5700 x 2450 the cost of this would be £16,261.00 plus vat supplied and fitted."
From other company
5700mm wide x 2450mm high -Three track Sieger Slim® sliding door system comprising of 2nr sliding and 1nr fixed panes (→,→,Fixed)
Alternative Option - 5700mm wide x 2450mm high -Three track Sieger Slim® sliding door system comprising of 3nr sliding panes (→,↔,←)
Original company (with double glazed units) have now said for the same cost they will do triple.
Anyway I've halved the price of 1 expensive unit already 🙂
