So I never posted any work pics so I had a quick project to do this afternoon and I took some pics to share with you guys.  On one of the house's the company I work for is building.  The architect wanted an large gable vent made out of azek so I was handed the task of making it.  Hope you enjoy.

First was to cut the 5/4" 4'x10' azek sheet to size and layout the vent slots.

[attachimg=#]
Next I used my c-12 drill and a 1-1/2" hole saw bit and made holes at the tops and bottoms of the vent slot locations.

[attachimg=#]
Now I used my ts-55 and guide rail to make the straight cuts connecting the holes.

[attachimg=#]
Then I used my trusty trion to finish the cuts.

[attachimg=#]
I then cleaned up the cuts with some granat hand sand paper, and rounded the edges with my 1010 router.

[attachimg=#]
Flipping over the vent I added a heavy duty screen materials to the back

[attachimg=#]
All done and ready to get installed

I think it looks good up there.  Was very easy to make and looks super cool.  Was a bit scary getting it installed as I really don't like heights very much.

looks nice, What is that stuff like to work with? Don't think we have a product like that over here
 
looks great dave. i too would be interested in a scource over here. it looks like it is 3/4" and like the material that a pvc fascia board is made of
 
Thanks guys. It is excactly the same as PVC fascia board material. Azek is the product name and also comes in sheets. It very easy to work with, my only complaint is the dust. Using festools help to manage it well. But the dust gets everywhere and sticks to your tools. This sheet was 1" thick and heavy. The core of this product is solid and it takes paint very well which is one of the reasons I use it.

Dave,

Great execution and appearance.  Is there a drain plane or provision to handle blowing rain getting inside?

To add to what Dave wrote, watch out for sharp edges and make sure you use the anti- static hoses.

The azek gable sticks off the house 12" and below it has vented soffit to match the rest of the house.  The inside cavity has house wrap on the plywood to protect it. So any water that gets in should drip out the vented soffit.

The anti static hose is key to help with the dust.

I like it! nice! 

Whats the reason for so much venting in the roof?    As you could of avoided all this need for mesh and draining if it was just channels half the depth and then painted black. 

sorry if im being silly!

Oh nice scaffold set up [eek] [tongue]

I hope there is not a ridge vent too, or that roof will be shot in under 10 years.

I do not like Azek.  I think it is over priced, especially if it gets painted.

I have made many a gable vent out of MDO.
 
Darcy,

I believe you're getting your info from the JLC forum as I've read about that, but you might want to explain your post for Dave.

JMB,

You can tell that's the mason's scaffolding as it doesn't come close to the area Dave would have needed to do the work, unless he's a really good circus performer.
 
A ridge vent and gable vent is not going to rot out a roof in 10 years.    It might not be the best setup but some houses don't have soffit vents or any soffits at all.  you have to replace the air.  as long as the heat is escaping, you'll be fine.

I think the vent looks awesome

Darcy, get with the program,  PVC is here and it's here to stay.  I don't mind working with Azek or wolf trim.  I don't like how it can expand etc.  I prefer clear cedar trim for exterior but not everyone can afford that, plus it HAS to be painted while pvc, its an option.

 
Yeah that wasn't the scaffolding I used. What i used wasn't exactly osha approved.  I use Azek because it will last forever, I don't have to paint it, most importantly the architect wanted azek.  The gable vent was made to the architects specs and as of now the gable vent isn't opened to the attic space.  The plywood for the gable is untouched and 12" back.  

Also I would like to know why the roof wouldn't last if the gable vent was functional and there was ridge vent?  I dislike working with azek myself but it will last forever and most of our houses are right on the ocean, bay or within a few miles of.  So azek is almost always requested by the architect.

Here are several sources of roof venting information.  The last one does include advertising by the company selling the products in the article, but still has plenty of useful information and other viewpoints to consider.

Aussieroofing.com

Roofhelp.com

Savenrg.com

So basically the "ideal" method is to introduce cooler air at the roof's lowest point and exhaust it at the roof's highest point with a 60% air intake to a 40% air exhaust ratio (slight positive pressure) to keep from drawing internally conditioned air out of the house, to a minimum of 50/50 while maintaining a proper airflow from intake to exhaust.

See, we have these people called amish around here.  They do lots of roofs because they are stupid cheap.  They like to put a ridge vent on everything.

Ridge vents and gable vents should not be on the same house, or at least the same attic space.

I have seen 3 feet of snow in an attic because of those 2 together and I have seen almost every roof with those two together bake and curl in under 8 years.

Heat goes out the gable vents and the ridge vent sucks it right back in.

I am still hold my position that azek and the like is way overpriced and I have no Idea what I should do with the scraps.

Burning them makes smoke like burning tires.  [cool]
 
Darcy,

I don't know if you are serious about burning PVC scraps, but if you are, here are some tidbits:

Ø        It only takes 5 ounces of burning PVC to give off enough hydrogen chloride gas to kill the occupants in an average size bedroom in ten minutes.

Polyvinylchlorides – PVC is used in the making of bottles and jugs, a variety of food, household, pharmaceutical and cosmetic products, children’s toys, blister and shrink packs, vinyl tubing, flooring and siding materials, drainpipe, vinyl fabrics and many other products.  When burned PVC produces carbon monoxide, dioxins, and chlorinated furans.  Dioxins and furans are two of the most toxic man-made products because the lowest amount of either product can cause diseases such as, cancer and birth defects.  Burning PVC can also cause hydrochloric acid in your lungs and cause possible ulceration of your respiratory tract.

I have tossed some scraps on a fire before, makes for some really black smoke.  Decided after that it may not be the best idea.

I don't like throwing it away either, because there is no way it will ever break down.

I must be getting conscious in my older age about what happens to stuff I throw away.  PVC scraps really bother me about what to do with them.
