How much Insulation for the winter?
So you have a newer home, Insulation is not a worry, Right? Wrong! Even homes built to code just two years ago probably won’t meet minimum levels required for new homes today. And don’t assume a brand new house even has enough attic insulation without measuring. Sometimes during construction things don’t happen the way they are supposed to.
So how much is enough? You’ll need to do some figuring. Start by aiming for a minimum of R50 as an end goal. R-value numbers aren’t a perfect way to measure insulation performance, but it is what we have to work with.
Here are some guidelines on the types of insulation:
- Loose, fluffy insulation in your attic it has a value of about R3 per inch.
- Blanket-like batts it’s about R4 per inch.
In either scenario, measure and calculate what you’ve got and you’ll know what you need to add. If you don’t have at least 16 inches of insulation in your attic you’re letting money waft out of your home.
Next you need to decide how to increase the insulation in your attic. Here are you options:
1: You can hire a contractor to come in and blow additional loose fill insulation on top of what you’ve got now. This is the most expensive choice, but it’s easiest on you.
2: You can rent an insulation blower yourself, putting on a mask and operating the machinery on your own. This is a rather noisy business that generally takes two people: one handling the blower nozzle on the end of a hose that snakes through your house and up into the attic, and another person feeding bags of loose fill insulation into the machine parked below.
3. You can install bags of loose-fill insulation meant to be carried to the attic and spread by hand. Again alot of work, but can be done with only one person.
What every option you pick, just take our advice and increase your insulation.
