Commercial doors, or ideas etc?

[borderboy1971]

I will be continuing a build of a 60x64 shop in the spring, and have been having a tough time deciding what I am going to do about the 14x14 doors. The best roll up door I can find has a r26 rating. My walls will be r38 (Strucural insulated panels). I have considered to make my own doors using SIPs, as it seems to me that it's a shame to have great r value walls and then lose all that r value with doors. Has anyone built their own doors with a really high r value? I know I could build some single piece swing out doors, or some bifold swing out doors, but I'm not sure if that's the route I want to go. Any suggestions?

A bit off topic, but can you point me to where you found an r26 roll up door? I'm looking for an insulated door, but can't find anywhere near that high insulation. The closest are the insulated slat doors. Got a price for one of those and

I'm not sure of the brand exactly that I got a quote for but it lists them as thermatite t300 series here in Canada. My quote was about 2800 each (14x14), but that doesn't include an electric opener or installation. I went on google and did a quick search and found Haas doors makes a r25.8 door called 800series, and Amaar has one in a r22.2. I have no idea though on the cost. I personally was surprised when I got my quote, as I had checked our local building centre and they could only get a r16 door and it was over 3000. I of course want to shop locally, but definitely am not willing to pay more money for a less efficient door. Ideally, I'd like to get into the r38 area if it's even possible.

I'm not seeing them as rollups. I could only find them as sectionals but they do look impressive and at a reasonable cost for what they are.

My rollups actually called Rolling Steel are insulated to about 7.5 if I recall. I don't believe anything above that is available in a rollup. The CHI rolling steel doors 10' x 8' were about $2500 each delivered but not installed. And very heavy ******* to install.

I love the CHI rolling steel doors but I'm far south of Canada.

My apologies, Yes they are sectional doors. I used the wrong term for the type of door I meant, sorry about the confusion. I am interested in a sectional door with the highest possible rating.

And yeah, I'd be surprised there are roll up doors with a very high r value.

BB,
I would not be as worried about the R value as much as how well you can get them seal out the cold air. If you get even the slightest bit of air infiltration it will negate any R value anyway.

I am only saying this because the ones here at my shop are terrible. When the wind blows from the west, I might as well just open them, that's how much air seems to come in on the sides Plan is for a major revamp or replace them this spring.

Do you have any windows in the shop? If so, I would go with the R26 doors and not worry about it. The heat loss through those things (and the associated dollars) will be miniscule compared to the heat loss through an R-5-ish window.

I would think the thickness of of a R38 door would also be a little odd.

I went with Steel Craft TD134 doors with SA7000 thermo pane glass panels. Mine are 10'x12'. They say it's R value is 16.4 I paid around $4,000 for both doors delivered to my fairly remote location. I'm very happy with mine.

The two posts above this one also make a lot of sense to me.

There are a handful of DIY swing out door builds on this site and I've seen them on other sites as well. The issue is always how well you can get them to seal up tight at seams and at the jambs, headers, etc. But that's that problem also exists with a sectional door, albeit maybe not as much at the threshold, which is harder to seal with swing out style doors.

At any rate, I've never seen a DIY carriage style door built from SIPs but I think it would be a great starting point. Light and flat and will want to stay flat.

I would want at least one overhead door where vehicles would be coming in and out of frequently but nice carriage doors in a few spots would be nice too if you can afford the square footage they'll need to swing into. I assume in Canada you wouldn't use a swing out door.

What's an SIP?

What's an SIP?

It's either a ******** Inverted Position or a Structural Insulated Panel. I'm guessing the OP is talking about the latter.

I'd be careful about using commercial doors. I have a total of 3 of them, two in the front entrance and one in the rear. Commercial doors, at least here in the states, have rib lines, (not sure if that is the correct term but you can see an example by looking at my build pics) which run horizontally. This design would not be preferred because air will be able to leak in each of the indented lines. If the indentions ran vertically or, at least didn't go all the way to the edge then you can use the weatherstripping that can be found at home centers that have the vinyl "sweeps" that run the length of a hard vinyl board. You can just nail them to the frame and the sweep portion is positioned against the door. The allows the door to continue to work as normal.

Sorry if my explanation is very good. Just let me know if you have questions as I am still looking for a solution as well.
