I'd appreciate some advice on window specs, we are looking to replace huge bungalow living room windows (have put off for 8 years but now condensation and rotten wood forces us). I got a quote for Rational alu-clad from ADW in Cumbernauld, these came in at around £6700. I decided to shop around and have now got a quote from http://www.russelltimbertech.co.uk for 'laminated timber' windows. This is coming in at just under £3000. Does it sound too cheap? Does anyone have experience of this company's products/service and 'laminated' softwood windows? Any advice greatly appreciated, thanks!
