We understand the charm and nostalgia that old family homes bring. The problem with them, however, is that they rarely keep the heat in. The solution is adding insulation to an old house.
Don’t rush the task, though. There are four aspects you need to think about first:
1. What to Do with the Old Insulation
In most cases, the existing insulation can be left as it is. It probably doesn’t help much but taking it down may not offer any benefits. The only real reason you’d have to take it down is if you need the space for the new insulation.
That can be a problem if you are using something akin to mineral wool. We propose a better alternative: Multifoil insulation. It’s very thin and light. Plus, it can be utilised together with just about any other materials.
It’s worth checking what kind of old insulation you had, however. Asbestos was commonly used in the past. In that case, you need to make sure it’s contained properly as it’s carcinogenic.
You may need professional help learning the composition of the insulator. Insulation vendors or contractors can give you the necessary advice and help.
2. What Material to Use When Adding Insulation to an Old House
Insulation has come a long way over the past years. Not only are today’s options much more efficient but there are more of them.
The different types of loose fill insulator are popular choices among self-builders. Cellulose is often seen as the go-to product for adding insulation to an old house.
The problem with that choice is that it will most likely become redundant like the old insulator. It will be useful for a few years but, in time, it will lose its efficiency.
Multifoil, on the other hand, has several advantages over loose fills:
- It’s airtight. Any harmful material from the previous insulator will be contained.
- Instead of absorbing heat, it reflects it. The foil ensures a pleasant temperature regardless of the season.
- It doesn’t leave a mess after being installed, and it doesn’t cause itchiness.
- It can be used in any part of the house, as it’s light and thin.
Now, the last advantage raises an important question, one that needs answering.
3. What Parts of the House to Focus on
When adding insulation to an old house, you have to think out of the box. Newer buildings are planned differently. What applies to a new home many not apply to an old one.
As with any building, most heat is lost through the attic. As a result, you should focus these. If possible, place the insulation in the roofing system or between the rafters. You get more space in the attic this way. You’ll be able to use the loft as a room.
When adding insulation to an old house, look out for wiring and lights. They can generate heat. Plus, insulating them can lead to fires.
4. If Moisture Will Become a Problem
Moisture is often a concern as it can lead to some complications. Peeling paint and moss are just the beginning. Old houses are at greater danger of rotting. You have to think about the effectiveness of the insulation and the integrity of the building.
To limit moisture, you generally have two options:
- Make sure the moisture barrier is facing towards the inside of the house.
- Get insulator that is unaffected by moisture such as multifoil.
Either way, it’s a good idea to keep an eye on potential signs of moss and peeled paint. This way, no problem will creep up on you.
