Hi Itchy

I am demolishing a house built in the 60s piece by piece and saving some of the materials and using them in a different house (such as the hardwood floors and 2x4 framing wood). I was wondering if it is possible to re-use the wall and ceiling fiberglass insulation. It has a foil backing on it and is easy to roll up. Can you tell me if it will be effective in another property?

Thanks

You could re-use fiberglass batt insulation depending on it's condition. If it is mashed down it has lost some of it's R-Value and you wouldn't want to use it. Also, you want to make sure it is free of insects and moisture. Installing wet insulation into wall cavities may lead to dry rot which will damage the structural members of the wall. But, if it's in good shape you could recycle it and use it in another area.... read more

Hey Itchy,

The wife is pestering me to get this house more energy efficient. I really can't afford to have a energy audit. Got any ideas?

You can check your home yourself to determine if you have any problems with saving energy. While your weatherization requirements will vary depending on what neck of the woods you live in the links below will point you in the right direction. Hopefully when you've finished your home energy inspection all will be well. If your results indicate you'll need to add more insulation and will need to break out the check book than I would say it would be ok to do a little cussing before you get started. What, you've never cussed out an under insulated attic? Well there is a first time everything!

For the most accurate results you may eventually decide to hire a professional home energy auditor. Here are some of the areas you'll need to check out when you are performing your do it yourself home energy audit... read more

Hi Itchy,

Bought a home a couple of years ago. It's about 20 years old and I'm suspecting it's probably lacking insulation in some areas. How do I determine if this house is up to code and if I need to add more insulation?

This is a big one. You need to make sure your entire home is properly insulated. Let's get the worst over first. Grab a light, ladder, ruler, goggles, dust mask and coveralls and go ahead and crawl into the attic.

Attics

1. Measure the depth of the insulation, where it's fiberglass batts or loose fill insulation. You'll need to contact your local county or parish building department to determine the recommended r-value required for your neck of the woods. You can visit my article regarding measuring attic insulation for more information.

2. Take a look at your ventilation while your up there. This may require some bellying around. Make sure the vents aren't cover with insulation and that they are properly baffled. If you have any recessed ceiling lights make sure they aren't covered as well. This could be a fire hazard.... read more
