Types of Wall Insulation

Installing insulation is one of the greatest methods to keep the heat in your house and the cold out if you want to keep your energy costs down and your carbon footprint low.

Because one-third of the heat lost in an uninsulated home escapes via the walls, it’s an excellent place to begin. You will save energy and money on your heating bill if your walls are properly insulated.

Of course, insulation may be applied to more than simply walls. Insulating your whole home, including inside walls, may ensure that your home is both energy-efficient and comfortable. Insulating your home properly will also lower your heating expenditures, making it a win-win situation. Let’s take a look at some of the most popular and effective types of insulation you can install in your home.

Cavity Wall Insulation

Your home is likely to have hollow walls if it was constructed after the 1920s. A cavity wall is composed of two walls separated by a space known as the cavity; the outside leaf is often built of brick, while the inner layer is constructed of brick or concrete block.

Many cavity walls may be insulated by inserting insulating material from the outside into the cavity. An installer will drill holes in the outer walls, insert cavity wall insulation, and then seal the holes with cement. Mineral wool or polystyrene beads are common insulating materials, but polyurethane foam can also be used.

Foam provides a seamless barrier that reduces air leakage and improves overall insulation performance. The effectiveness of this method, according to Phantom Foam Insulation, depends on selecting the right material and ensuring professional installation. This approach can significantly improve comfort while lowering heating and cooling costs.

To insulate your hollow walls, the installer drills 22mm holes at 1m intervals on the outer wall of your home. The installer then uses specialized equipment to blast insulation into the cavity. Once all of the insulation is in place, the installer plugs the gaps in the brickwork so that they are scarcely noticeable.

Filling cavity walls is a job that requires the services of a licensed installer. For a normal house with easily accessible walls, a professional can do the work in around two hours. It should be a clean and tidy process.

Internal Wall Insulation

Internal wall insulation is the application of insulation to the inside face of exterior walls in order to improve the property’s thermal efficiency.  This is ideal for properties with solid walls, where there are no cavities that can be filled.

The most popular (but not always the most effective) form of installation is to create a new stud wall to which insulation can be added.

Internal wall insulation can be disruptive and involves the removal and re-installation of objects such as switches, radiators, and kitchen cabinets, so be sure it is the best insulation choice for your home. Because creating an airtight layer is critical, problematic places such as reveals and floor gaps must be handled with care.

Radiant Barrier Insulation

Radiant barriers and reflective insulation function by reflecting radiant heat, as opposed to most ordinary insulation solutions, which impede conductive and convective heat movement. Radiant barriers are put in houses primarily to prevent summer heat gain, which helps to lower cooling expenses.

Radiant heat moves away from any surface in a straight line and warms anything solid that receives its energy. A radiant barrier inhibits radiant heat transmission from the underside of the roof to the attic’s other surfaces. It must face a broad air space to be effective.
