    Wrapping the ends of joists to prevent damp transmission (Ed.)

    The joists sit inside a single skinned Bungaroosh wall in Brighton. The wall has no cement and a low content of lime. Frankly the houses here are shocking! A mistake nearly all homeowners make is rendering their houses in cement mortar thinking that it will add strength to what is otherwise...

    Wrapping the ends of joists to prevent damp transmission (Ed.)

    I need to change many of the original floor joists due to rot. Typically joists are wrapped in DPM using stable gun for example. I’m wandering if there’s a better way such as foil tape. Any thoughts would be most welcome.

    Reinstatement of roof support

    Well, I guess the ridge is resting in the gable walls and some, albeit not enough support is given by two ashlar walls resting on two a pair of 2x (8x2) beams bolted together. Its not great and I eager to reinstate support the day I get the keys! Just hope the roof doesn't fall on my head...

    Reinstatement of roof support

    Hey folks, Im about to buy a victorian terrace house with a gable to gable roof. The previous owner decided to remove the perlins and struts and make a non BC approved loft room! The Ashlar walls are supported by two 8x2 timer beams which have been calculated to be about a quarter of the...

    Under floor heating

    Thanks DP, I have MV’s for the Ch and HW as usual. So the pump that drives the water around the primary flow and return boiler and tank isn’t powerful enough to drive water around the UF circuit, so the second pump is a booster. Have I understood it right?

    Thanks, yeah the pump etc are supplied with the kit which is why I didn’t mention it.

    Under floor heating

    hi there, So my CH is an Vented system. I want to install UFH into a new extension. Rather than plumbing into existiting secondary flow and return for rads, I’m told the best way is to create new flow and return control with its own motorised valve. To avoid the pumped return spilling into the...

    Solid floor construction.

    Thanks so much for your reply Pilsbury. The ground for the most part is untouched. It’s 30 square meters. There was one drain which disturbed some ground. I’ve already spread the mot and am having to take some out because I’ve over done it. It’s a killer as I already compacted it. The screed...

    Solid floor construction.

    Hi all, I’m in a quandary. My extension is 340mm from excavated ground to finished floor level. I will be installing underfloor heating so the order of materials from bottom up is as follows; Hardcore Sandbinding DPM Concrete slab Sand binding to level imperfections Rigid insulation Underfloor...

    Warm roof VPC location?

    hi there, I'm putting 50mm of kingspan tp10 between the 8x2 rafters, 18mm ply ontop of the rafters then 100mm of kingspan tr27 on top of that. Confused as to where the Vapour control barrier should go. I guess on the underside of the tp10 between the joists. The only type of VPC that would...

    7.3n vs 3.6n aerated blocks

    hi all, Apart from the obvious difference, has anyone had any experience of fixing wall cabinets to both of these materials and does the 7.3n offer more strength in this regard. If not I'll save my money and go for the 3.6n's

    Brickwork for raising hearth

    Hi there, I'm going to put a bio ethanol burner inset into a granite plate which will rest on about three course of brickwork raising the floor of the builders opening of my fire place. The problem is that the burner requires 230mm of depth and the depth of the fire place is 360mm. The only...

    Creating a form for pouring a concrete path!

    Hello, I want to pour a path and have previously used 12mm ply with timber steaks used every 30cm. Due to cost I want to know if anyone has used a cheaper material like OSB? Love to hear

    Verdict, a year or so on!

    The usually open valve fitted to the bypass reduces return temperatures and means that well balances radiators will contribute to a return with a 20 degree diff from the flow. This optimises condensing which saves money, and it stops the boiler from cycling as often. Radiators also get...

    Common Flow temperature reading

    Hi all, I have clamped a pipe thermometer to the common flow immediately emerging from the boiler. With a return temperature of 40 I still only get temperatures of 60 max on the flow with the boiler pemeprature set to max. According to WBosch a 15ri max temp ought to be 82. I bought...
