    Investigating how long loft insulation lasts can help you organize your house maintenance budget for years ahead. This is very useful no matter if you plan on living in that house permanently or if you intend to sell it at some point in the near future.

    General guidelines

    Many manufacturers provide a general estimate of at least 70-80 years for the lifespan of their insulation products. However, this estimate is based on ideal conditions which may not always be present. It’s important to understand that in most cases, loft insulation will not last that long, especially if you live in an area with harsh weather conditions.

    Even then, you should expect to get at least 50 years of use out of your loft insulation if you take good care of it. It doesn’t take a lot of effort to keep your insulation properly maintained, and it’s a good idea to familiarize yourself with the necessary steps from as early as possible.

    How to increase the lifespan of your loft insulation

    There are various things you can do to increase the lifespan of your loft insulation and get the most out of your investment. Here are some important points to consider:

    • Avoid any physical damage to the insulation
    • Deal with moisture problems immediately
    • Don’t heat up the loft too much – check the insulation manufacturer’s guidelines for optimal temperature ranges
    • Take care of any animal problems, like mice, as soon as you discover them
    • Keep the air in your loft fresh, and ventilate the place as often as you can by opening the loft hatch
    • Make sure your insulation is installed properly in the first place, and get it done by a professional

    Keeping all of these points in mind can help your loft insulation last for a long time. Even if it does get accidentally damaged at some point, it shouldn’t be too hard to repair the issue locally instead of replacing the whole insulation.
