    Vinyl tiles: corners not meeting

    Our installers are about half the way through laying 45cm Expona vinyl tiles and there are locations where the corners seem to be 1mm and 2mm out, and one spot where there is a 3 to 4mm mismatch. (I just counted 26 corners out by at least 1mm, though I counted quickly and may have missed...

    LED specific fitting type?

    I was planning on fitting GU5.3 or GU10 downlighters with a view to fitting LEDs later into those fitting. Obviously with that arrangement anyone could switch back to halogen afterwards. Having read some of the negative opinions on downlighters as being fire traps, I'm wondering if...

    Velux flashing: EDZ vs EDW for 16 degree pitch

    I've bought EDZ flashings to be used with Velux windows as instructed by my builder, roof to be fitted with Marley Mendip tiles. The roof has a pitch just over 16 degrees, and I now see that EDZ is intended for 20 degrees plus, whilst EDW is for 15 degrees plus. The builder is insistent...
