    Partially threaded Direct concrete fixing fasteners

    The last lot of builders I had in used self-threaded concrete fixing for just about everything, saving them from having to mess around with rawl plugs. They seem pretty nifty. Obviously you're not going to hang a picture frame up with them, but for other stuff they seem ideal - like fixing stud...

    Plastering over a steel embedded in a wall

    I have a plaster concrete block wall which has a steel running through it; this has been plastered over. Over time the steel, under the plaster, has developed a surface rust and you could see where, even through the plaster and paint, and a crack had formed on the lower edge. I have stripped...

    How to fix a tongue and groove ceiling to rigid board insulation

    I am creating a vaulted ceiling, rigid board insulation will be fixed on top of the rafters (forming an air gap with the slates). I'd like the final ceiling finish to be tongue and groove wood cladding. Probably running vertically, rather than horizontally. I'm just not sure how I'd go about...

    Tinted double glazing panels and thermal efficiency

    I am having some windows made and the joiner and I have to decide whether or not I want tinted window panels. They're tinted for thermal efficiency. Compared to untinted double glazing they are 1.9U vs 1.4U. Which seems pretty significant. My house gets very little direct natural light and I...

    Double or Triple glazing for bespoke wood frame windows

    I am getting the old and rotting windows on my property replaced with bespoke hardwood framed windows. At a minimum they're going to be double glazed, but given the costs involved I am wondering whether I should go for triple glazing. If it makes any difference, the windows don't actually get...
