More windows....

2 rooflights fitted (2 still to go). Unfortunately I ordered 2 at the wrong size - biggest cock-up so far. 200mm too tall and I only worked it out after I'd opened a box, so return not possible - want to buy a rooflight anyone? Because they're snug between the purlins there's no chance of making them fit, so one is going back for a hefty (25%) restocking fee and 2 replacements are due any day now. Manufacturer is Keylite - seem to be competitively priced compared to Velux with a better U-value (1.0) on the standard range. Fitting was straightforward once we'd deciphered the international pictogram instructions...!
