Hi I wanted to put this in the rendering plastering trades section but couldn't click on that topic title for some reason. Has anyone rendered onto external polystyrene insulation? Its actually the base of my founds an EPS insulated raft. The two products i'm looking at are Aquabase EWI 226 a silicone render system with a fiberglass mesh or a cement slurry aquamat elastic with either 10cm polyestewr fleece or fiberglass mesh Anyone done this before and got any advice on either product or covered their EPS RAFT base in anything else that worked well? Cheers

Problems with how to finish reveal with aluclad windows
cbk posted a topic in Plastering & Rendering
I'm about to get windows installed and the fitter has pointed out an issue which I'm not sure how to solve. House is an ICF build (Isotex) so all window reveals have to be covered in something to hide the blocks. External finishes are a mix of render (K-Rend Silicone) Stone Slips and Cedar cladding. Windows are Ratinonel Aluclad and structural openings have been made to the size of the window + 5mm fitting allowance. Original plan was to fit the windows and then render the reveal up to the face of the window for a neat finish. Fitter has pointed out that the Aluclad finish may need to be removed for general maintenance of the window and should not be rendered over. Worse still he has suggested that the render may cause moisture to trap behind the aluminium cladding causing the timber frame to rot! When done right there should be a slight shadow gap around the edge of the window which adds to the modern look. My guess is depth of the reveal will be about 50mm so this is a narrow strip that needs to be covered somehow. Only idea I can think of is to use an aluminium flashing the same colour as the window that will be thin enough to fit under and aorund the window and then use a stop bead to render up to the edge of window opening. All sounds a bit fiddly and might end up looking like a dogs breakfast. Any other ideas would be most welcome. -
We've finally approved the drawings for our timber frame house and the erection is slated for January. Time to order our windows. The supplier and the price are both sorted, but something that cannot be agreed upon is whether the windows are installed before or after the house is rendered. MBC and Velfac are adamant the property should be rendered first. Our renderer says not. What has everyone else done in this situation?
