Polycarb canopy project

[kjacko]

Hi,
so i want to erect a 6m x 1.5m polycarb canopy spanning from the house to overhang our existing shed and 'maybe' have the guttering connected to the shed so that rainfall runs off the canopy onto the shed and into the guttering which will then go into a water butt.
10mm sheets @ 1m x 1.5m. I'll do it myself, but i know little about what parts i need.
Wanted to find a local supplier so i could pop in and have it all explained to me.
Anyone know of a local place near to Nottingham city centre?
Online quotes are grand, but need to see what i'm going to have to play with when erecting.

Thanks

Forget 10mm at a metre wide it will eventually sag in between bars. 16mm will be good. Is this a cantilever type thing or are you fitting a wall plate and eaves beam?

Have u got a sketch?

Hi, sorry, wasn't aware i'd gotten a response.
10mm twinwall seems to be the norm for a canopy and my design is pretty much standard as far as that goes.
4x2 timber wallplate. 4x2 joists 2m long spaced every 1m (obviously), with a baton at 1m down from the wallplate, so prety much looks like a standard roof frame i guess.
One thing i don't know is how to put each sheet in as surely i can't stand on 10mm sheets.
So, screw the glazing bars to the 47mm wide joists, put the sheets in, but i'd have to be on the roof to actually snap down the lid of the glazing bars. this is where i'm coming a bit unstuck and would appreciate any advice.
I'm pretty sure that 10mm will be fine as everyone i've approached so far has said it will be.

I'm pretty sure that 10mm will be fine as everyone i've approached so far has said it will be.

So why bother coming here for advice?

 

[kjacko]

Really?!
I never asked if 10mm would be good enough, because all the advice i've had so far says that it will be for my needs. I welcome all advice, doesn't mean i'll take it though. If you've nothing to offer constructively feel free to move on.

 

[freddiemercurystwin]

I advise you to go elsewhere

 

[kjacko]

Thanks for your advice.....i'll not take it on this occasion though. There are plenty on here who ARE helpful, so maybe they'll pop in sometime and actually be helpful.

Have you already put the joists in place? If it were my house I'd use self support bars. A 4mself support bar will do you two joists cut in half. It's more expensive than timber supported bars but from underneath it will look like a professional conservatory type roof with no timber to be seen. It's easy to fit without being on the roof.
We fit about 3 poly jobs a month and do loads of refits too. 10mm poly eventually curls a little and a loose roofing tile will slice straight through it. For about £18 per square metre extra you can go up to 16mm and a tile won't go through it and it's nice and sturdy.

We fit 35mm on our jobs. My wife could disco dance on one of those babies and won't go through it and she's a huge momma.

 

[kjacko]

Lol, no dancing required. Thanks, i do appreicate the advice, but i really am on a budget, and its only really a shelter for when we go out to the bins or if i'm doing some DIY outside and need to be dry (it will overhang the shed so wil give be 2 completely protected sides..
The self supporting method would cost be about £780 in total (got 2 different quotes). As it stands, i've bought the treated 4x2 timber for £90, and the 10mm sheets with glazing bars, eaves filler, 'F' bars, end caps, screws, silicon etc will cost about £270, so much much cheaper.
Ideally i'd love to use self-supporting bars but as its slightly bespoke anyway (i'll allow rainwater to run onto the shed then into guttering wrapping around the shed into a couple of water butts) and its pretty much double the price.......well.....there ya go i guess.
I will be putting batons in so the 10mm sheets will be secured at approx 1m x 1m internvals so to speak.
I also thought it would be much easier to secure lighting and power cables and fittings to timber rather than PVC.
The timber will be stained the same colour as the shed as it will tie into it. I received a sample of a brown glazing bar but it doesn't match so i'll go with white.

I did consider an even cheaper option, using corrugated plastic roofing. That's how tight the budget for this project is.

 

[kjacko]

Ok, back again. I'm asking for a requote to show the difference in going for 16mm but i think its going to be beyond my budget.
So, advice again if you please. How on earth do i install the sheets onto a timber frame. There are videos that make it look straightforward but they don't actually show some geezer laying it down and snapping down the bars. Do i stand on ladders, poke my head between the joists between where the 2nd sheet will go, whilst laying the first one down? If so, then when i snap down the tops of the glazing bars how do i then install the 2nd sheet (with the bar already snapped down)? I can't see how it can be done with standing on the roof (using roof planks).

Last time I assembled a conservatory with a similar challenge (not wanting to stand on the 28mm glass) I got the two glass panels in place, then got bottom end of the bar in place and partially snapped it on with my hand, then used a 10 foot length of 2x4 timber to act as a long-reach mallet, working my way up the bar. Worked a treat.

 

[kjacko]

Lol, sounds like fun.
Yes, after thinking about it i could probably reach across 1m with a mallet to gently 'bach' down lid of the glazing bar.

 

[Mw Roofline]

Yes, fit end bar, lay sheet then next bar then sheet then snap down the end bar and the second bar you need long arms!
Don't fit and screw all the bars first, all the diyers do this and it's wrong. Fit end bar, then place next bar up to sheet then screw bar in place. Do bars as you go along unless you are a pro at working out the first bar perfectly square on.

 

[kjacko]

Thanks, i was thinking of not ony fitting each bar as i cgo along but each rafter too, that way i can't go wrong. (can i?)

 

[Mw Roofline]

Erm I suppose so lol.

Have you bought the poly now or still pricing up?
