Installing Loft Insulation
Before installing any type of insulation, it is important to prepare the loft space properly. This involves clearing the area of obstacles and rubbish and ensuring the loft floor or ceiling is strong enough to support the insulation. Additionally, homeowners often ask if they should remove old loft insulation before installing new insulation or if they can put new insulation over old. We explore the answers to these questions below.
Preparation for Installation
Before installing loft insulation, it’s essential to prepare the loft space to ensure a safe and effective installation. Firstly, ensure the loft is well lit and free of damaged joists, as this may cause a collapse. You should also make sure there’s a safe, sturdy working platform to stand on while carrying out the insulation work. Crawling boards supported by at least three joists are ideal for this purpose.
It’s necessary to remove old insulation and vacuum the remaining dust before installing new insulation. You may also need to hire a professional carpenter for repairs if necessary. Once the loft is free of debris, check for proper ventilation and consider lagging pipes and water tanks with suitable insulation to prevent freezing.
To keep you safe while installing the insulation, it’s vital to wear protective clothing and equipment. A face mask and gloves are essential to avoid inhaling dust or coming into contact with any skin irritants.
Lastly, consult with a professional installer for a thorough assessment, and identify the minimum depth of insulation suitable for your roof space. With proper preparation, installing loft insulation can be a straightforward task and will provide numerous benefits, including reduced energy bills, and a minimised carbon footprint.
Should I remove old loft insulation?
If you’re wondering whether you should remove old loft insulation, the answer is — it depends. You see, insulation can last for decades if it’s in good condition. However, over time, loft insulation may become damaged, compressed or damp, rendering its insulating properties inadequate.
If your loft insulation is over 20 years old, you may want to check its condition, depth, and coverage. Also, if you’re experiencing draughts or high energy bills, it might be time to inspect the insulation. Damaged or missing insulation can cause a quarter of your home’s heat to escape through the roof.
If the existing insulation is damp, it could lead to mould growth, which could harm your health and damage your home. In this situation, you may need to remove the old insulation and rectify any underlying issues before installing fresh insulation. Similarly, if you have old vermiculite insulation, which may contain asbestos, it’s best to call in a professional to handle the hazardous dust safely.
To determine if you need to replace the insulation, you can inspect it yourself or hire an expert to do so. Checking for proper coverage, the depth of the insulation, and for any signs of damage will give you an idea of whether it needs to be replaced. If you do decide to install fresh insulation, always ensure that it’s installed to the manufacturer’s guidelines and that you have adequate protective equipment.
Can you put new insulation over old?
Wondering if it’s possible to add new insulation over old insulation in your loft? The answer is yes, but there are a few things to consider before you start.
Firstly, it’s important to note that the R-Value of the total insulation thickness must comply with the UK Building Regulations. This means that you must make sure that the new insulation added on top of the old insulation will meet the required R-Value in total.
Secondly, a vapour barrier should be in contact with the plasterboard surface to prevent moisture build-up but should not contact any insulation as this could lead to condensation issues.
Blanket insulation, such as mineral wool, and loose-fill insulation can typically be installed over existing insulation. However, if the old insulation is damp, water-stained, compressed, or contains asbestos, it should be removed before installing new insulation.
Old insulation that is damp or water-stained can lead to mould growth and cause damage to your home. A compressed insulation will not provide adequate insulation, while asbestos-containing insulation is hazardous to handle and must be handled by professionals.
By following these best practices, you can ensure that your home stays energy-efficient while keeping your living space safe and healthy.
