Do this before the Insulator arrives, It’s $300 well spent!

Huge thanks to our Show sponsors USG/Tremco, Polywall, Huber, Dorken Delta, Prosoco, & Endura for helping to make these videos possible! These are all trusted companies that Matt has worked with for years and trusts their products in the homes he builds.

Best time to walk the house is just as the sun is coming up and walk the house with spray paint and you will see every spot daylight is penetrating the home. Mark all spots with paint then go back and foam or caulk all these air penetrations. Do not forget to caulk all the sill plates at the floor. This must be done right before insulation after all MEP's are done. Doing this will seal up your home very well and if you are building to Energy Star ratings this is a must do.

I've always like this thumbnail because it describes the challenge of the order in which trades do what. If the electrician comes last, the walls are already closed and there's no opportunity to seal those huge gaps where the Romex comes into the box.

One of the best content creator on Youtube when it comes to Building ( if not the best). You sir are inspiring .

[mgaming]

i love these types of videos because it seems like Matt hates all bugs as much as I do. Anything to keep any creepy crawlies Outside is worth a watch and a like.

Important note. If you live in the southern hemisphere, you walk the house in a counter clockwise direction first.

Yes! Love this type of video! DIY friendly! Please start/continue a DIY Tip series/playlist!

Hey Matt...Love the thought that you put into your videos especially with regards to the insulation. As an owner of a spray foam company in the Northeast, you should never spray water or introduce water to the substrate prior to or after spraying. Chemically what happens is that the ISO (harder) reacts with the water before it reacts with the POLY (resin) thus losing the 1:1 mixing ratio. In the field this is known as B (resin) rich which causes the foam to pull from the substrate as seen at the 7:19 mark in the video.

I would like to also add that the quality and materials with which build house are best I’ve seen...you don’t find hardly any contractors that do the kind of work your company does. Thx for your workmanship it doesn’t exist anymore these days in my opinion.

Do you need to worry about compatibility with the electrical cables and other plastics?

Here in NZ, you absolutely cannot run PVC cables in contact with polyurethane or polystyrene foam insulation unless it's the special purple cable or is protected by flexible conduit or similar - it rips all the plasticiser out of the cable and makes it brittle.

ZGreat video Matt! Doing a whole house remodel soon and we will definitely do this,

[colebevans]

Hey Matt, where I live they changed code on electrical outlets last year. All of our plugs and switches have a rubber gasket around them that gets sealed between the poly and the drywall. Not sure if you've seen them before but they make a really nice seal. All the houses we build here are so tight that they need high velocity air exchangers to pump fresh air into the house.

I have seen these kits usually for about $550. They seem to work great! however, you need to keep spraying after you start, if you stop spraying for more than 30 seconds you need to replace the nozzle. so get a few extra nozzles when you order this stuff.

We build in a climate where temperatures can vary from 110 F in the summer to -40 F in the winter.  One thing we have had to do when using closed cell foam around pipes and ducts (plumbing, HVAC etc.) is to install a fiberglass wrap of insulation prior to spraying.   With the extreme swings in temperature the pipes and ducts expand and contract so much that they will make loud popping sounds if the closed cell insulation is sprayed directly onto their surfaces.

And then add an air-exchanger to the home..makes sense.

Nice informative video, but I do have a couple of questions.
Do you have any regulations in the U.S regarding the contact of foam insulation with cables? Here in the U.K you can't bury cables in foam as the styrene content destroys the elastomer in the cables pvc sheath resulting in early deterioration in insulation resistance etc.
Also if you bury a cable in insulation, for every 500mm the cable will lose approx 50% of it's current carrying capacity.
I'm not criticising your methods, I'm just interested in how other countries operate.

What gets me the most is the fact that you don't use pvc piping for your electrical wiring troughout the house. In the netherlands we firsy place pipes and then pull the wires trough those pipes. Blue wires for the zero, brown for the fase, green/yellow for the grounding and black for the switches.
We use the (what is called) "NEN 1010". Which is a description for building electrical systems in buildings.

[teknophyle]

This is a good video to also highlight issues with data/low-voltage wiring. I constantly see sub-par wiring installed, even in new houses. Once that is sealed inside insulation... game over... decent wiring will have to be installed on the outside of the house. Data wiring will always need to be upgraded every 15 to 20 years anyway so it really should become common practice to install smooth flexible pipe or conduit to every data or TV outlet in the house. Will save a ton of time effort and money upgrading data wiring in the future.

Wouldn't be great to have someone like Matt as a close friend went you need some help around the house?

[harryballzack]

GET THE SUIT!!!
And like he said COVER your hair!
This stuff is messy. Extremely messy! But it does a great job.

This same kit is over $600 on Amazon now.
