There’s a story behind this as we had to find a solution to a problem with regard to the dimensions of a sub-cill and how to measure them. As to which is required depends on whether you’re installing an aluminium bi-folding door, sliding door or window. You also need to give consideration for the floor and wall construction and Building Regulations. It also depends on what cills are available and appropriate to the design and/or aesthetics of the building internally and externally. Aluminium Sub-Cill The eaves beam cleverly double’s as an integral box gutter utilising the support posts as down pipes with the rain water exiting through the variable height post feet. Threshold: This door comes with a standard point; you can upgrade to Low Aluminium Threshold in the options above. Cill options are available. From a functional perspective, R9 windows are distinguished by their nine-chamber design. This configuration ensures superior thermal performance and sound insulation, providing a high degree of comfort for homeowners. The windows are available with double or triple glazing, with triple glazed units achieving impressive U-values as low as 0.8 W/(m2k). This level of energy efficiency is particularly beneficial for homeowners looking to reduce their energy consumption and contribute to a greener future. Moreover, the robust construction of R9 windows ensures exceptional durability, promising long-lasting performance that your customers can rely on. Please note : The 1.6m relates to the length of the slope, therefore the horizontal projection will vary dependant on the selected roof pitch.

I just wanted to continue from this thread as it not too old and also most relevant I could find (and has an image I refer to) so hope that is ok to do. Every French door we make is manufactured to offer high energy performance with toughened 28mm double glazed, Argon filled Glazed Units. Why buy French doors from us? Mine more resembles the example on the left.. so more of a pointed tip than a groove... I assume both would do the same job..? Or should I look to get another with the grooved tip..?!? The height measurements must be from underneath of any existing removable cill unless no cill is required.

You say the sill was attached to the frame before fitting. If it was screwed from underneath, you will need to take the whole frame out and sort it properly. Plan of action if screwed through frame. Remove screws, reposition sill. If the front gap of 6mm appears, you can fill with loads of silicone all the way along and re-screw tight. Silicone will squash out, clear excess(especially drain holes area. Then make sure sill is supported underneath, and silicone all the way down side of frame and over sill(get some in that little gap than runs to the wall under frame on top of sill.
