jayc89 Posted August 30, 2022 Share Posted August 30, 2022 I'm planning on battening down the hatches in preparation for winter. I'm almost certain there's a problem with our loft insulation as there are a couple of rooms that are mafting (technical term) in the summer and freezing in the winter. Currently there are a couple of layers of mineral wool, but they look pretty worse for wear and have compacted down to not much more than 75mm in total... When we build an extension next year we'll likely go with blown cellulose over the ceiling joists but for now I'm thinking just an extra couple of layers of mineral wool to see us through the winter and hopefully keep our energy costs at a more manageable level. Totally coverage is approx 65sqm. Can anyone recommend the best place to buy cheap mineral wool rolls from? Or even a cheaper solution? Link to comment Share on other sites More sharing options...
nod Posted August 30, 2022 Share Posted August 30, 2022 Last time we used Wickes I think they where similar to the builders merchants But where doing buy two get the third free Link to comment Share on other sites More sharing options...
JohnMo Posted August 30, 2022 Share Posted August 30, 2022 B&Q normally compete on best price, look at both their websites to see which is cheaper. Also take a look at insulation hub website. All the builder merchants around us are way more expensive than B&Q. Link to comment Share on other sites More sharing options...
Conor Posted August 30, 2022 Share Posted August 30, 2022 (edited) Usually B&Q when they've something like a 3 for 2 offer on. Put a couple layers down. First one, 100mm across the joists and then another 200mm the oppotsie way. Don't push too far under the eaves. fix any gaping holes in the ceiling while your there, esp around light fittings. I'd do it sooner rather than later as I can see a rush for insulation and anything to do with energy saving happening as soon as the first cold weather bites. And it's a days easy work (overalls and dust masks a must) Edited August 30, 2022 by Conor 1 Link to comment Share on other sites More sharing options...
jayc89 Posted August 30, 2022 Author Share Posted August 30, 2022 (edited) The cheapest I've found is 150mm Knauf 44 rolls (9.18m2) for £39.95 + free delivery on eBay. I've seen some advertised for less, but when you add delivery (£50 from most places!) they come out more expensive overall. Anyone seen anything cheaper elsewhere? We already have some insulation up there, so I was planning on just rolling another 150mm across what we already have.
