How to Insulate a Cottage
The right insulation will help keep your cottage a warm place to be even in the coldest months. (cottage image by Jaroslav Pohl from

Cottages are popular as vacation homes, but old houses aren't always built to modern standards, and as a result tend to be poorly insulated or susceptible to mould and moisture. To make your cottage a more liveable place in both the hot summer months and the cool winter months, you might need to better insulate it.

Skill level:

Things you need

  1. 1

    Choose an insulation material that is right for your budget and needs. Batt fibreglass insulation is an affordable option, but installing it requires dealing with itchy fibreglass. Rigid foam insulation is a more expensive alternative, but it is a better defence against mould and moisture. It also traps air better than fibreglass insulation.

  2. 2

    Remove any previous insulation and replace it with new insulation. Uninsulated areas with exposed framing should be as stuffed with insulation as possible, especially attics and under the floor. Insulation from older cottages could be a hotbed of insect and rodent infestation, so wear gloves, goggles and long-sleeved clothing.

  3. 3

    Check windows and door frames for any gaps that might be letting in drafts. If necessary, install weather stripping to better insulate these areas. Your range of options for weather stripping is quite broad, starting from inexpensive felt options to higher-cost metal stripping. Part of the beauty of having a cottage is letting the outdoors in, so avoid caulking or sealing windows or doors shut if possible.

  4. 4

    Use strategically placed fabrics to further insulate your space. If a major renovation of your insulation structure is not an option, use fabrics. In cooler months, place thick drapes over your windows to absorb some of the chill from the glass. Cover the floors in heavy rugs that will help to keep your feet warm. In the summer months, remove thick rugs from the floor. Use a window treatment such as mini-blinds to keep some of the heat out.
