Setting The Cill
The cill needs to be fixed to your base there are a number of points to cover.
The Cill is supplied over size and needs to be cut to size, This will help if your walls are slighty out and you need any extra room to make the cill level.
Your cill must be square to your wall to check this measure across the diagonals to the corners the two sizes should be the same.
The top of the cill needs to be level use packers to raise the cill where required and ensure you fix the cill securely this will ensure your glass fits well when the porch frames are fitted. If you cill is not level you will notice the glass panels are not quite square to the pvc frames.The gap under the cill can be filled with silicone or a mortar mix.
Setting The First Frame
The first frame will be screwed to the wall however you should not allow the frame to be pulled out of square use a level on the long open side make sure the frame is plumb. Then use packers to fill the gap between the frame and the wall where you intend to add the fixings the packers are to prevent the frame pulling out of square when you tighten the frame anchors.
To hide the joints between the fames and add strength to the frame fixings a h esction profile is added to one frame as shown in the picture the h section and the frame are then lifted against the first frame.
To ensure both frames are fully into the h section use two frame g clamps to squeeze the frames together and produce a tight joint leave the clamps on until the frames have been screwed together.
The frames are screwed together through the side where the glass will be fixed later this means the fixing screws will not show when the porch is finished. The screws should be fixed from both sides of the frame. Three screws per side is ok and the screws should be a staggered heights on the two side of the frames.
Use g clamps on the corner post top and bottom to ensure the post is held tightly the screw the frame in to the post once the first side is fixed add the next frame use the g clamps to hold the frame in place and screw in to the corner posts.
Reinforced Corner Posts
Depending on which type of porch conservatory you have ordered the corner post may end flush with the frames or it may only be flush with one frame as shown in the picture. The corner posts are reinforced to add strength to the corners and prevent any warping.
Check the frames are correct on the inner side of the cill then check they are square and the corners posts are near plumb. If all is well which it should be screw the frames down into the cill as shown. The screws go where the lower panels or glass will be fitted so they will not show when the porch is completed.
Build The Roof Frame Structure
To make the roof erection easier it better to build the aluminium section of the frame on the floor then lift it onto the porch after its built. Once built you can lift the roof onto the window frames and use the roof as a guide to mark out where you flashing will need to be fixed.
Do not forget the lower sides of the roof bars have plastic covers which need to go on before you bolt the roof together.
Lift The Frame Structure
You will need some help to lift the roof into place on top of the frames once its on top of the frames you need to line up the inner side of the ring beam with the inner face of the frames.The roof is fixed by screwing up through the frames into the bottom of the ring beam.
Glazing The Roof
You can add the polycarbonate sheets to the roof you need to start with any square sheets you can glaze the square sheets however if you have any sheets which meet a hip corner bar the top cap does not go on the roof until the hip corner bar cap is fixed.
Place the sheet into place and push it up in to the ridge section ensure a gap is left both sides of the sheet to allow for expansion.
End Bar Top Cap
Add the sheet closure to the bottom of the sheet please note the sheet closures for angled sheets will not be cut to size. Line the plastic cap up with the bar below as shown then tap the cap into place.
Mid Bar Top Cap
Add the next section of polycarbonate then add the mid section top cap as shown. Top caps can only be added where they meet the flat ridge the top caps that meet the hip bar go on after the hip bar cap. These caps are supplied over sized puch the cap down and fix a small section onf the cap then tap on the bottom of the trim to push it up tight to the ridge. Tap the whole cap down in to place then cut to size.
Hip Sheet Closure
The hip closure will be supplied over sized you need to add the sheet closure to the sheet hold in it place on the roof. Mark the angle of the roof and cut as shown in the more information page. We do this because the roof panels and the sheet closures come from different factories.
Fix The hip Cap
Next fit the hip cap as shown the hip caps are similer to the mid caps except they are taller. The hip caps are shorter then the roof hip bar so line up the bottom end of the cap with the roof bar as shown.
Hip Mid Bar Top Caps
The top caps that meet the hip bar cap can now be fitted. Start by tapping the top of the cap into place by the hip cap. Tap the top 6 inches or so
