If a house has plastic vapor barrier on the inside walls and a foil barrier on the exterior of the house should you remove the existing old outer foil when residing?
Unless your home is heated by electric baseboard you may take it down if you wish. However the foil has reflective heat values, which means it reflects out the heat from the sun in the summer and reflects in the heat in the winter.

No lime is not caustic-lye is.
Answer . 2 to 6 ml. visqueen is commonly used as a vapor barier on the inside of exterior walls, before drywall installation, if that's the application that you are referri…ng to.
Paint with bleach and then clean with high pressure hose
Aluminum foil can act as an energy barrier, but not a very good one. It is not very dense, therefore an electron (energy) can penetrate it. Because it is not very dense the mo…lecules are not very close together it is not very good at passing energy along, which makes it a poor conductor, but it still can pass energy so it is not effective at preventing energy transfer.
If the exterior walls have tyvek on them do you need to put plastic vapor barrier on the inside walls?
No. You need to let the house breathe.
If you are not allergic to them, go and buy some spray that kills the bees. Let it set, then once all the bees are gone you will have to rip open the wall get the hive out, th…en repatch the wall and make sure when you do this you seal all the areas that bees can get back into. If you are allergic to be stings then I recommend that you call out a bee keeper for the job.
This can vary though most typically it a 2, 3 or 4 layer structure incorporating an aluminum or metallised aluminum layer to provide the key barrier performance. It will have… an inner layer of polyethylene that is readily heat sealable and also provides protection to the key aluminum layer and robustness to the overall structure. This layer can be clear or pigmented and there is a range of types of polyethylene that each bring other attributes such as higher oil/grease resistance, stronger heat seals, sealed with less energy or faster throughput. The top layer will typically be a transparent layer of Polyester or Nylon to give, high puncture resistance, and also add to barrier to gases. A further layer of this can often be incorporated between the foil and the polyethylene layer to protect the foil from sharp, granular ingredients and to boost tear resistance still further if required.
Barrier Foil laminates has 80 times more protection to moisture vapour ingress from 500 gauge polyethylene.. They provide a good cost effective, flexible alternative to heavy… duty plain plastic pouches and bags.. With added benefit of total/near total barrier to gas ingress such as O 2 , N 2 , CO 2 etc depending upon the specification chosen.. They can offer excellent light fast protection to prevent colour fade or spoilage by UV light.. They provide good hermetic barrier to prevent biological effects such as mould.. Flexible nature makes it format friendly, easily fabricated in 2 or 3 dimensions to make barriers of all shapes and sizes.. Readily heat sealable with correct heat sealing equipment to give all of the above.
Typically they are made-up of two, three or four layers incorporating an aluminum or aluminum metallised film layer in the middle of the structure to provide the key barrier p…erformance. Most frequently, the inner layer is made of polyethylene (PE), as it is readily heat-sealable and also prevents contact between the aluminum layer and the packaged contents. It also contributes to the robustness to the overall structure. This PE layer can be clear or pigmented, and there is a range of specific PE layers available which can offer further attributes such as; higher oil/grease resistance, or super-strong or quicker heat-sealing. The top/external layer of the laminate will typically be a transparent layer of Polyester or Nylon which gives high puncture resistance, and also adds a further barrier to gases. In certain circumstances, a further (fourth) layer can be added between the foil and polyethylene layers to offer protection against especially sharp, or abrasive contents or provide added tear resistance.

Yes, you can print on them, either on the surface or more typically, with the print buried under the clear top layer of Polyester/Nylon to give the print protection and added …gloss. Furthermore, foil pouches can include re-sealable "zip-lock" strips for ease of re-sealing. Your pouches can also feature "easy open" tear notches.
These foils can be hand fabricated in smaller quantities (typically for bigger pouches and 3 dimensional bags and shrouds). They can also be supplied on the roll, for use on f…orm-fill-and-seal machines and high speed packing lines.
Do you put the vapor barrier of insulation on the inside or outside for an exterior wall application?
Inside, after the insullation, and wiring
Foam is inserted into walls for two main reasons. Insulation is the primary reason, while fireblock is the second. Foam insulation can be injected into the wall of an exist…ing building without much destruction (typically just a series of one-inch holes to be filled). It increases the R value of a wall from about 2 up to about R11. It also cuts off air leaks and can cut off entry points for pests. Some (not all) foams are highly fire resistant. They can keep fire from racing up through the stories of a home. Foams also can help with sound deadening.
Much-but it also blocks the light. Day sleepers use this trick all the time.
Basically, it's a type of clear polyethylene sheet like painters use.

First thing to do is read all instructions before installing radiant barrier foil. Make repairs to the area that you are planning to insulate. Unroll the radiant barrier and… cut with scissors or knife. Staple into place.
