2nds Slightly broken-in sandstone canvas and an insulated, quilted lining make Carhartt's double front a warm, comfortable choice in cold weather. These insulated work pants are great when you don't want to wear a full set of insulated coveralls while working yet want all the same cold weather protection of a coverall while working. Warm tough heavy outer denim smooth thin thermal inside side zips enable easy on or removal with shoes or boots on I bought one size larger in waist and 2 inches shorter than pant size, to fit over shorts, sweats, or other light pants.
It will depend on the user wearing the pants, because the pants can be worn with or without layers. One way to repair this problem is to remove and replace the glass while leaving the window unit in place.

Where do you buy the double thermal pane replacement glass that goes into the aluminum frame? I have done every thing you say to do for sweating on inside windows and storm doors , nothing has worked and they are double pane and hign end doors and windows.

Pumice chimney systems were first used to build chimneys in Denmark specifically for stoves.
When it is not possible to get enough draw to make a fireplace or stove work properly you need an Exhausto chimney fan. If a stove is to be fitted into a fireplace then the throat of the fireplace has to be sealed off using a register plate. Sweeping your chimney is essential for your safety as it removes the tar and deposits that cause chimney fires. A stove needs a supply of air to burn properly, and often this means that a supply of external air is needed to the room where the stove is installed. You know by now that we’re all about finding the best bang for our buck when it comes to energy efficient construction. Double stud walls on 24″ centers is the easiest and cheapest built thick wall cavity. Cellulose is economical while also being the best green insulation product known to man (see future post on cellulose superiority).
One of my hopes in posting this hypothesis is that one of you guys out there will prove us wrong and give us a better wall assembly that packs more bang for the buck.
Excessive exterior insulation – As we stated above, rigid insulation is not cheap and has a larger carbon footprint than many other insulations. ICF’s - Expensive, built of harmful foam, hard to get a high r-value and filled with concrete. Big ass SIPs – These have the same problems as excessive amounts of foam as that is what the core is comprised of.
Blown-in Fiberglass – Substituting fiberglass for cellulose would decrease your costs slightly while achieving the same R-value. If you enjoyed reading this post I can promise you'll love our new writing over at Postgreen Homes. So is there an advantage with the wet-spray, do you still achieve a “dense-pack”? Now I’m looking to build and among many questions, wonder about the cellulose insulation.
I’m not totally sold on the need for all of the cross bracing between the two stud walls. In addition to this we are considering sheathing the entire inside of the outer stud wall with OSB to act as our primary air barrier that would tie into the subfloor as well as OSB under the roof deck TJI’s. What makes our goals so difficult is that we are trying to create a Passive House level wall (Super insulated, Super tight and zero thermal bridging) on a budget that can be built quickly in a production setting. Most of the Passive House walls we are seeing in our research from overseas use this middle layer of OSB as their primary air barrier. With controlled indoor humidity and a tight envelope that limits convective moisture transfer, the temperature of the sheathing is not an issue.
But, with exterior foam board, there is little to no drying potential to the outside, so moisture accumulation becomes a much more serious problem. I couldn’t agree more that air movement contributes far more to vapor transport than diffusion does. The EMC of the sheathing also depends on the permeance, hygroscopicity and capillarity of adjacent materials on both sides as well as the combined drying potential due to thermal and convective forces.
Remember, even saturated sheathing is not a problem as long as it’s too cold to grow mold or decay fungi and can dry out before it gets warm enough to become an incubator.
Thanks for the clarification about RH, EMC, etc…This certainly helps me to see the big picture more clearly. I need someone to clarify the moisture and condensation issues presented in differing posts regarding vapor barriers.


Let me be more specific as to what I have in mind and then I will accept any advice from those with more authority, which I will assume is anyone with experience in the area of super insulated wall construction.
Planning a small (1000 sf) single level home on a sealed crawlspace in cold weather (northern Wisconsin). You seem to focus on the insulation in the walls but forget that the worst heat losses or gains will be through your windows which might be R5.
Sure, in cool to cold climates, high-spec windows will always lose more heat than high-spec walls. I see a lot of concern about the weakness of windows in your superinsulated homes and suggestions about superwindows.
The pictures will slide over to cover the windows when it is cold and especially when the room is not in use. Here is a table listing all the possible combinations of IP ratings along with a short description.
A square inside a square means the appliance has double or reinforced insulation, to prevent a dangerous voltage reaching any exposed conductive parts in the event of a fault. Whether it be projects around the house or shoveling snow these pants are my do everything get it done work pants. However, over time the seal separating the two panes can break, allowing outside air and moisture in that can fog up the glass. In addition to posting comments on articles and videos, you can also send your comments and questions to us on our contact page or at (800) 946-4420. We offer black enamel flue pipe in a standard matt finish, or glossy if specified, or stainless steel flue pipe.
Pumice chimneys are especially well suited for use with wood burning stoves and because of the insulation value of pumice they suffer less from tar condensation than more traditional materials and are very heat resistant. Our register plate is made from 2.5mm steel, has a hole for the flue pipe, clips to hold it to the wall, a clamp to hold the flue liner or a sweeping trap.
The inline chimney fan is turned on when you open the loading door to add more fuel which prevents smoke coming into the boiler room. Heat proof render is suitable for rending the inside faces of fireplace openings which are likely to get heated by the stove or fireplace. With our range on chimney sweeping brushes and rods you can sweep almost any flue pipe, flexible liner, or chimney stack. A stove room ventilator makes a simple job of providing this ventilation, and at the same time ensures that it is waterproof, pest-proof, and wind-proof. Carbon Monoxide is a risk if your stove is badly installed or badly maintained and the alarm, fitted near the stove, lets you know if the CO level is rising too high.
Both material costs and labor costs are extremely low compared to alternatives (TJI’s for instance). It’s not uber cheap or low in the carbon footprint category, but used sparingly, it can be quite effective. The big downsides are that it has a much higher carbon footprint, virtually no thermal mass and does not resist airflow, crippling it’s advertised R-value in the face of any air movement through your walls. Yeah, we know that's the same thing your favorite band said and their new album is nowhere near as good as their early stuff, but seriously, we are actually still getting better. If the wet-spray had the advantage, then I’d be willing to put up with the drying period. Used around the foundation and under the slab (where other materials don’t perform adequately) IS sparing use of a high-footprint and expensive insulation material. I don’t disagree with your comment and wall assembly and have been giving it a lot of thought lately. We are currently looking into basically the same detailed wall, except we are bringing the subfloor all the way out to the exterior of the outside stud wall which ties the two walls together with minimal thermal bridging at each floor deck. This creates a Passive House level air barrier that is very easy to detail and tape all the way around the envelope from inside the house. In addition to it’s contribution to insulating and eliminating thermal bridging, exterior foam can raise the temperature of the interior surface of the sheathing, shifting the dewpoint outside of the cavity wall and allowing much more flexibility in the choice of interior vapor retarder. And, with a highly hygroscopic and moisture-buffering insulation like cellulose, minor incidental condensation can be stored, redistributed and released without consequence – particularly if the structural envelope can dry to the outside.
And, because the exterior foam board maintains the sheathing at a higher temperature, any amount of moisture accumulation can result in mold or decay. Specifying an interior air barrier in a cold climate is typically my first line of defense, when it can be installed effectively. The relative humidity (RH) of the air adjacent to the sheathing determines the equilibrium moisture content (EMC) of the sheathing (or other hygroscopic material). I would go one step further and suggest that it’s probably unwise to assume the perfection of even one layer for the life of the building, including the air barrier.
The comment “we are bringing the subfloor all the way out to the exterior of the outside stud wall which ties the two walls together with minimal thermal bridging at each floor deck.
In particular, what would be the moisture issues in an exterior wall if the wall was built with moisture barriers on both sides?
Let’s say the foundation walls are ICF, and a strong moisture barrier to seal the crawlspace floor.


The exterior foam panels could meet flush and seal with the foam from the ICF foundation walls, and the interior of every room sealed on the inside wall with a vapor barrier of plastic or foamboard.
If any, could a simpler wall system like this be somehow modified to eliminate or reduce this moisture? But doesn’t make more sense just to use window panels to raise the insulation level of the windows.
This means that any equipment that is double insulated must not have an earth, as this could impair the protection of the double insulation. Yep, the classic mason jar has been re-imagined with double-walled insulation to maintain the perfect temperature of hot or cold beverages, a redesigned drink-through and splash-free lid that includes a reusable, smoothie-sized straw, and a handle on the side. Carhartt knits have a generous fit, with the exception of our Work-Dry shirts, which fit closer to the body.
I have taken these out in the early winter and they keep me more than warm enough with a little base layer underneath. Pumice chimneys cope well with the thermal shock of a chimney fire and should be used in favour of terracotta liners when forming a chimney for a stove. An inline chimney fan is also a way to improve chimney draw if all other avenues have failed. Heat proof plaster is suited to plastering the same openings and to plaster around, behind, and infront of stoves. We have super flexible nylon rods for those bendy flues as well as standard rods for unlined chimneys. This will be our best wall assembly to date and most likely the wall we will stick with going forward. R-10 is the minimum amount needed in most US climates to mitigate dew point issues that could cause moisture in your walls. Eliminating a full foundation and building on a shallow, frost-protected grade beam further limits use of high-impact materials. They then build another 2x wall inside that that houses all electrical runs, is load bearing for the floor decks and gives a nice wall to drywall that does not need to be airtight. In some projects (timber frame structure with 2×4 infill walls and exterior foam insulation) the air barrier is likely to become compromised due to wood movement. For instance, 80% RH results in an EMC of about 16.5% which is enough to initiate and sustain mold growth. I am sure there are issues that could be addressed but it seems more important to prevent air and moisture flow from BOTH sides of living space. Throughout the house, including the crawlspace, an independent air exchange system between interior and exterior.
Again, air flow within the home and to the outside controlled by a ducted air exchange system. Triple glazed, unshaded, south facing windows at latitudes up to about 55 degrees generally have an annual net gain.
If your north windows are kept small and you add thermal shutters wouldn’t this work as well as high r windows?
The only downside is that all food preservation abilities have been lost, but if you splash a little bourbon into your drink, you won't really care. Privacy Policy5568 Cool New Items Discovered Since The Beginning.Proudly Made From Recycled Pixels.
When taped, it also can virtually eliminate air penetration and double as a water resistive barrier allowing one product to serve three important roles. Lastly, going over 2″ in thickness in exterior insulation will drive up the cost of your fasteners and labor required to attach your exterior cladding to your framing underneath. We believe TJI walls are too difficult and expensive in the US and your modified Larsen Truss walls or the one I have described above in this comment would be superior in the states. I would rather trade a bit of material efficiency for a little redundancy in my walls if it means they will stay functional over time and with changing conditions.
And the local RH at any point within a thermal envelope depends on the vapor pressure on each side and the relative vapor resistance (inverse of perm) of each element.
How much does a wall need to really “breathe” if the wall system itself is completely air and moisture impermeable from both sides?
This would be a much simpler wall system than double wall systems; easier to build despite higher initial costs.
So come on over to the Postgreen Homes Blog and tell us what you think of our new(ish) digs and crazy ideas.
Of course there could still be convective looping of air from one interior location to another, but if the sheathing temp. I am building for myself and plan on both exterior thermal shutters that can be closed and pictures on with 2 inches of foam behind them. Sealing both inside and outside should reduce moisture transfer to the interior of the wall, but I am open to the suggestion that I am completely off base here and would like to understand why.
