Many homes have twice as much insulation in the attic as they do in the walls to protect against losing warm air. The cost of labor to install insulation averages between $0.25 to $0.50 per square foot. The overall labor cost depends on what type of insulation is installed. Batting insulation can be a quick installation process, while spray foam takes more time and preparation. External or ‘solid’ wall insulation is the most cost effective and comprehensive way of insulating your home against the Irish winter.
Here’s some guidance on what you need to budget for and why quotes might vary. It costs between $1 and $4 per square foot to insulate a pole barn. Many insulation professionals recommend spray foam or fiberglass batting with a thick polypropylene sheet. Spray foam is pricier, but it does a better job at preventing air leaks.
What Are the Benefits of External Insulation?
It is more eco-friendly and comfortable to use than some other batts because it does not contain small glass particles. It can be used in attics, crawl spaces, and open cavities in walls and ceilings. The cost of cellulose insulation averages $0.60 to $2.30 a square foot. The dense-pack material is more commonly used in attics and crawl spaces. Home ranges from $4,950 to $35,000, depending on where you insulate and what type. Most people spend between $4,950 and $10,000 on a home this size.
Please take the time to add your project, to help other’s looking to complete theirs. Upgrading your home’s efficiency, especially when using natural materials, will drastically improve your property’s carbon footprint. So, if sustainability is at the heart of your renovation then you might see external wall insulation as good value for money.

For example, installing batts in open walls can be fairly simple and does not take much effort, although it can be time-consuming. Spraying insulation into open walls can be done more quickly, but it requires more skill and specialized knowledge, impacting the labor cost. It is often used in ceilings, interior walls, and other flat areas. It is a natural material and considered a more environmentally friendly option than some other types.

Please note that depending on the time of year we may need 2-4 weeks notice prior to installation. External wall insulation cannot rectify rising damp coming from the ground as this is due to a faulty damp course. This problem must be rectified by a specialist before we commence installation of your insulation.
What Does External Wall Insulation Cost?
If your house was built after the 1980s you probably have cavity walls, so cavity wall insulation would be better for your house. Demolition and removal of existing insulation will drive up project costs considerably. Contractor labor for normal demolition runs from $70 to $80 per hour plus disposal costs. Commonly referred to as SIP, structural insulation panels are more of a type of wall than a type of insulation.
The guides describe the materials and the benefits they deliver to your home. Then, we list the insulation costs of each level of insulation, something known as the R-value of the insulation. The “R” stands for “resistance.” The R-value gives you a numerical level for how well the material resists the transfer of heat. The higher the R-value, the better the material keeps heat in your home in the winter and out of your home in the summer. Adding insulation to the interior is a good first step in preventing thermal transfer.
For this reason, you may want to insulate your pipes as part of a larger project. This is because pipes can have condensation on the exterior. This condensation can cause mold or mildew issues when paired with other insulation types. The pipes must be covered in a vapor barrier if you use other insulation. The cost of rockwool or mineral wool insulation averages $1.40 to $4 a square foot. Mineral wool is made of recycled furnace slag spun into fibers.
Your solid walls are unsuitable for cavity wall insulation, so external insulation is what you need. Spray foam insulation is a rigid insulating product that’s created by a chemical reaction that occurs at the time of installation using a spray gun and equipment. It’s applied directly into wall cavities or on masonry surfaces. Options include closed-cell and open-cell types and have differing qualities and applications. Insulation by Material – We offer comprehensive insulation information for the major types of insulation used in construction and remodeling.
More options are included in the most recent 2021 IECC, including combinations that include exterior and cavity insulation. Some companies promote EWI systems that incorporate mineral wool. It is available in a range of thicknesses to accommodate local requirements and codes. The Flat roof on the Garage was insulated with 100 mm PIR and a Trocrol Rubber Membrane finish. When opting for a provider, it’s important to ensure that they will use both adhesive mortar and fixings to secure your insulation panels.
The cost of fiberglass3 insulation is $0.40 to $1.50 a square foot. It comes in batts and loose-fill and can be used in most interior spaces. It is common to use the batts in wall cavities and between floors when installed in new construction.
Some are affected by moisture, others by rodent or pest activity, and many types can settle, shred, or become less effective with time. If your goal is to provide long-lasting insulation, you may have better results with some materials over others. The following breakdown gives you the average lifespan of each type. The Dublin homes below show the external insulation work done and example prices, showing you that getting your home so late on a very cost-effective option. It costs between $1 and $5 per square foot for insulation, depending on the type. A 1,500-square-foot home could cost between $1,500 and $7,500 to insulate.
If the indoor temperature changes drastically once the furnace or air conditioning unit turns off, the insulation may be to blame. Another way to avoid discomfort is to select insulation that's designed to minimize itching. One product utilizes curled fibers that are less likely to irritate, and another type sheathes the insulation in a plastic sleeve. She is a writer and editor with nearly a decade of interior design expertise.
Before we had homes with cavity walls, solid walls were the norm and had been the norm for centuries. Unfortunately, solid walls sometimes failed to stop penetrating rain from getting into homes. Today, we often use a combination of exterior home insulation and cavity wall insulation.
It seals tiny gaps in the home’s exterior where thermal transfer may occur. Use a vapor barrier2 with this insulation because it causes condensation and mold and mildew growth. Home is $6,600 to $45,000, depending on where you insulate and the insulation type.
