23 August 2012: [Extension] The single most expensive item for the extension is the WINDOW, this will be over 2 grand, including installation and VAT. We have placed the order now, with INTERNORM, one of Europe's leading window companies (will be installed by Newport-based Spectrum Installations)
We sent invitations for tender to Internorm (Spectrum), Rationel (Ravensmoor), Benlowes and Livingwood. We chose the Internorm on price and on the fact that it has the additional foam thermal break in the frame giving it the lowest U-Value of all the windows considered. All windows considered were for the highest performance triple glazing with timber structural frame and aluminium skin externally.
