Cold bridging around the external window reveals and potentially between the joins of the insulation. Ideally the joins should be sealed or foamed to help prevent this happening.

Hello, could you advise what kind of bead to use to make nice border line on semi detached house or just to use a corner bead? Do I need to use a base track with clip drip beads around the roof line on one story extension and what width to leave between roof tiles where lead work and eps on the wall. Using 50mm eps. 1.5mm render. Thanks in advance

After the Grenfell Tower disaster some insurance companies are requesting any external cladding system used must be made from a fire resistant material. Polystyrene insulation while different from what was installed at Grenfell, is being seen as a potential fire spread risk. Small numbers of mortgage lenders are now insisting this is removed from any building before agreeing to any sale. The insurance industry sees any suspect cladding material as too risky and will refuse cover.

@nigelsmith1198 2 жыл бұрын

Lee Thornton, I asked EWI store about this subject as I’m halfway through putting it on my place.! Once rendered the system is difficult to ignite so can’t see why insurance companies are being a pain in the Arse.! It’s one of the most used materials for external insulation.

@leethornton6395 2 жыл бұрын

@@nigelsmith1198 Hi Nigel yes it will be very difficult to ignite and the risk especially on low rise properties to occupants would appear minimal. In the organisation I work for we are having to survey all our low rise buildings that have cladding and in the very near future probable the houses with cladding also. As a company the insurance of the buildings is a major issue and we will be unable to cover the buildings if the insurance firms see any potential risk. You only have to look at the problems asbestos caused in buildings and insurance firms refused any cover if there was a potential risk so certain types of asbestos had to be removed. This is all an ongoing issue but you can be sure if a building with cladding went up in flames and the cladding was known to be a risk and not removed any insurance cover could in the future be void. Has we stand now nothing has been finalised but be aware even if the risk is low the cost of getting insurance could be very high sometime in the future. At the moment it is all in a state of flux.

Can i apply the primer onto painted concrete/clay bricks. Can i apply onto wood? I got old house where a wooden beam sits ontop of walls throughout house. Then the roof sits ontop of that? Would i get any thermal gain by adding it onto the wooden beam? The beam seems to be thick enough to keep nice thermal delta.

Hi James! There are two ways - 1. You can extend the roofline or 2. Install a robust capping profile or verge trim. You need to double check if you are going via a funding scheme as they may only allow option 1.

XPS is normally used as an insulation below the DPC or as an insulation on balconies due to its water repellent properties. XPS density is circa 200 or 300 grade for these applications.

Looks like a good system but has a major flaw , what happens if you need to replace the window? This system does not allow for that as the base coat and thin coat both encroach on the window frame . Not good 👎

@stegra5960 2 жыл бұрын

But that's the case with all rendering. Windows are generally cut out and the replacement measured to fit between the render, ideally slightly wide and shuffled in before being screwed to the sill. If the frame is narrow on the inside, trims are used, but they're normally used anyway.
