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. -
I'm having a go at this dry lining, and contrary to most advice I'm using Fermacell (all previous comments re Fermacell are spot on, I'm using 1200x1200 boards) I've been making all my mistakes in a walk-in wardrobe where they won't be easily seen and have now ventured into the spare room to see what more mistakes I can make in what will be a seldom seen room which leads to my question. We have inward opening windows. The airtight tape is fixed to the timber frame and wraps around onto the window frame by about 30mm. The gap between the internal reveal and the inward opening casement is about 50mm. It looks to me like it's going to be difficult to get into this space between the reveal and the inward opening casement on the hinge side. A bit of plywood packing first so that the Fermacell will hide the tape should do it but then how do I get the FST on to the Fermacell or, indeed, paint it, on that hinge side. Is there a simple way? Alternatively I guess I could line the reveal with timber that is finished prior to fitting? Easy to say...
