try these boys,http://www.soundglobal.co.uk/profile.php ,i've had stuff off them in the past on a supply only basis and thought it was pretty good(can't for the life of me remember what profile they use),they are just off junction 21 of the M6 near warrington,and yes they delivered down here.the windows you want are known as,either,woodgrain on white or rosewood on white,the two are slightly different,even so,all it is,is white profile with woodgrain/rosewood foil laminated onto the front face.heat can be a factor,but if they are well made and well fitted you shouldn't have any problems. i put some in for an aunt about 2yrs ago and she's had no problems,touch wood.hope this helps.
