Exterior INSULATION Details from Matt’s House

Exterior Insulation Company for My House

In this video, the speaker talks about how to install exterior insulation on a house. He explains the benefits of using Atlas poly iso insulation and how to correctly install it.

Benefits of Foil Facing

• The foil facing on the insulation has a radiant barrier that reflects the sun's energy back, making it more energy-efficient.

• An air gap is needed in front of the foil facing for it to function correctly.

• When an airspace is created in front of the foil facing, it radiates the sun's radiant energy through.

Poly Iso Insulation

• Poly iso insulation has a high R-value per inch, making it an excellent insulator.

• Installing a thick blanket of poly iso insulation on the outside of a house provides continuous R-value everywhere and prevents thermal bridging.

Preventing Condensation

• Installing exterior insulation can prevent condensation from forming inside a house, especially in northern climates.

Overall, this video provides valuable information on how to install exterior insulation on a house using Atlas poly iso insulation. The speaker explains how to create an air gap in front of the foil facing and why installing exterior insulation can prevent condensation from forming inside a house.

Exterior Insulation and Air Sealing

In this section, the speaker discusses how exterior insulation can prevent condensation in humid areas and keep heat out of the house in hot and humid areas. The speaker also talks about how he wanted a well-insulated house to reduce energy bills.

Using 2x2 for Base Plate

• To prevent foam from hanging out on the bottom, a 2x2 is used.

• It is screwed into the base plate of the house all around.

• A piece of big zip tape is placed over it to protect against bugs or insects coming up.

Bug Screen Protection

• Cheap aluminum bug screen is stapled onto the sheathing.

• When 1 by 4 battens come, they will be stapled onto them for bug protection.

Cap Fasteners

• Cap fasteners from Rodent House are installed using a cordless device that sets depth.

• They work really well and hold foam temporarily until installation of one by fours.

Taping Seams

• Foil face tape is used to tape seams on joints.

• This provides radiant barrier factor as well.

Vented Attic

The speaker mentions that there will be no breaks in insulation from foundation to ridge so that his attic will not be a traditional vented attic. All of his attic will be part of the air-conditioned envelope on the house.

Exterior Insulation Deep Dive

In this video, the speaker discusses the installation of exterior insulation on a house. He explains how it works and its benefits.

Installation Process

• The wall foam is installed first and then the rafters are run.

• The ledger board is lagged on with long spax screws.

• The framing is outboard of the insulation, which goes from the foundation to the ridge continuously.

• Two layers of 2-inch foam are installed on the roof deck, and the wall insulation goes continuous all the way up to the roof.

Gable Areas

• Rafter tails were built on top of the roof, and they poked out by at least 2 inches so that wall foam could go right into it.

• The guys did a nice job cutting where the roof meets at an angle.

Efficiency Benefits

• Exterior insulation makes a huge difference in house efficiency because there's a continuous blanket on the whole outside of my house.

• It's like putting a ski jacket on compared to just stuffing insulation between your ribs.

• There's also a foil face on the outside to give us that radiant barrier benefit.

Product Recommendations

• Rodent House has great products for installing exterior insulation, including cap fasteners and specific blades for both knives and saws.

• Atlas sponsored this video.

Conclusion

In conclusion, exterior insulation can be easily installed using foam boards. It provides significant energy efficiency benefits by creating a continuous blanket around your home.
