April 13, 20251 yr I had a look at a new site recently. Good job was done on the blockwork I thought. The PIR Was installed in the usual fashion, far far from the worst I've seen mind you. Gaps between boards, wall ties not fitting correctly, mortar droppings on the boards etc. I maintain it cannot be accomplished to a satisfactory standard in real life and shouldn't be attempted. Bonded EPS beads or mineral wool batts are far superior. Edited April 13, 20251 yr by Iceverge
April 13, 20251 yr And I bet the builders will be saying what a good job, a nice insulated house.....
April 13, 20251 yr A lot of sites now blow the beads in afterwards But even these tend to settle Or end up und the Block and beam
April 13, 20251 yr I'm told, and I believe it, that when selling a house telling the world it’s a self build is taken as a big negative - peeps would much rather have professionally built houses. My guess would be the above would be less likely in a self build where the self is actively involved in the build. Odd world innit.

April 13, 20251 yr He certainly will be rouge when it’s pointed out to him, if he’s got any pride that is.

April 13, 20251 yr Author At a guess I think this if for an external precast threshold. I'll keep an eye when I'm passing. It's a shame the boards are used. It's a generally well done site otherwise.
April 14, 20251 yr A recent build near me uses the same boards as these. The inner leaf was built several rows ahead of the outer leaf. No snots. Boards installed flat against the inner leaf, with all joints foamed and taped. It's frustrating that this is notable. It should be standard practice.

April 14, 20251 yr I totally agree with most of the PIR products, but still think this one is head above the rest with its engineered parts that prevent a lot of the issues mentioned: https://unilininsulation.co.uk/products/cavitytherm/ct-pir-cavitytherm/ This is also the only system with purpose made components for different areas of the build, not relying on someone cutting them by hand and cocking it up Edited April 14, 20251 yr by MikeGrahamT21

Xtratherm used to have a similar product maybe they just changed the name.

By far the best system I’ve come across and used
