What should the centre spacing be for 690mm sheets please? The installation instructions online don’t give 100% clear advice apart from the 2mm expansion gap either side of the panels. I’m presuming you allow 50% of the 21mm i think it was mentioned in the instructions per side too for centring purposes?
Great questions, so the width of the centre part of the Snapa bar is approx. 16mm so plus a couple of mm for expansion and that would be the amount to deduct off each sheet. You only minus the deduction once from the sheet width as it is split 50/50 either side. Check out our polycarbonate glazing bars installation guide for more info: clearambershop.com/collections/snapa-snap-fix-glazing-bars Axiome® polycarbonate sheets are super easy to cut to size on site (see our how2 video) so if you aren't sure on the exact spacing they can be ordered oversize and trimmed easily. Hope that helps?
Thank you for the video. One question: do you install anything on the end of polycarbonate sheet where it meets the masonry? I can’t figure out if I can leave it like that because there will be flashing tape on top or whether I need end stop bars there too?
Yes, you would install a Snapa Top Wall Flashing to seal over your polycarbonate sheets at the back/top wall. This helps prevent water from running down the wall and creates a proper waterproof flashing. If you were using Alukap XR Anti-dust breather tape on the bottom of the sheets you would also use it on the top. We also have a How-to video about installing the Top Wall Flashing which you may find useful: ua-cam.com/video/cHzVnv2VXv4/v-deo.html
Hi. I'm hoping to replace the polycarbonate sheets on my conservatory roof shortly, it was installed about 28 years ago, the company no longer exists, so would it be possible to get the new sheets from my local DIY store ? I'm assuming they would be a standard size.
Hello Nigel, there are some standard polycarbonate sizes but stocked stores tend to be limited in size options. Check our our site below for the widest range of polycarbonate sheet sizes. Our Axiome Polycarbonate Sheets can always be cut to size for free, if desired, or trimmed down easily on site. clearambershop.com/collections/axiome-multiwall-polycarbonate-roofing-sheets Hope that helps?
@ClearAmber Thanks for the reply, I'll have a look on the website see what's available, hoping to do it fairly soon when the weather improves. Thanks again.
Would it be ok for me to silicone all the way down where the sheet and the glazing bar top cap meet just as a precaution? So basically doing that on both sides of the bars at every point where the sheets meet them?
Yes, it's not usually required but if you wished to silicone down the edge of your glazing bars and polycarbonate sheets you could. It is important that you use a sealant that is compatible with Axiome Polycarbonate Sheeting - it is recommended to use our Securbond Sealant that we specifically designed for this.
Thanks Myles, great question. Using polycarbonate fixings alongside the Snapa Glazing Bars is optional. If you have a sensible polycarbonate sheet width and rafter spacing they won’t be required. However, if your sheets are wider or in an exposed location then the Alukap XR Fixing buttons can be used on purlins to reduce the risk of wind uplift. Hope that helps clarify?
Hello Richard, good question. It depends on your roof pitch (steeper means less overhang so the water doesn't overshoot) and also how far your gutter is sitting below the End Stop Bar. As a rule of thumb, people tend to aim for 40-50mm overhang for a polycarbonate roof.
Is it possible to install glazing bars and sheets one at a time from underneath ? Im using the snapa glazing bars and my lean to is 4m wide and 2m long
Yes, it would be possible to install your Axiome polycarbonate lean to from beneath, working across sheet by sheet. The challenge is the last polycarbonate sheet however, as you will need to be able to access the roof from above/beside to secure the last glazing bar. As your projection isn't huge you may be able to access from the front for this last panel. Trust that helps?
Thank you for your question. We used our Alukap-XR End Stop Bar for sealing the ends of the polycarbonate sheets in this video. The benefits of using this product are that it has a good size down stand for creating a proper drip and also is aluminium for great longevity. How that helps? Here's the link to our video about installing the End Stop Bar: www.clearamber.com/news/108/How-to-Install-ALUKAP-XR-Endstop-Bar-.html
Great question! It is always safer to go for more polycarbonate sheets at narrower widths for stronger resistance against rain/snow loading and wind uplift. This also helps towards making your lean to roof last longer. We would rarely suggest going above 1m widths and for thinner thicknesses, like 10mm polycarbonate, we would suggest much narrower than 1m. Hope that helps?
Ultimately, the right sheet width to use depends on the thickness of Axiome® Polycarbonate Sheet that you are installing (plus location/structure type etc.) so please contact our team directly via our website for more specific help: www.clearamber.com/contact/

Do you need to use the screw buttons into the polycarbonate? Or is it optional

Hi. How much longer should the polycarbonate and bars be at the cutter end for the rain water to hit gutter?
