FAQs

how to insulate a loft?

Do you know about 25 percent of heat that escapes from an uninsulated house are lost through the roof? Fortunately, roof insulation is something that can done by all DIYers irrespective of their experience levels. However, if you happen to lack the confidence necessary to pull off this, then it’s strongly recommended that you hire the services of a professional who can guarantee the best results and also save you time and money that could arise from potential cost mistakes. Let’s take a look!

  • Clear out all clutter. This involves taking out all the rubbish and clutter from the loft. In order to work effectively, you’ll need a totally clear and empty loft space.
  • Ensure that there’s sufficient insulation. The importance of a good ventilation cannot be overstated. Poor ventilation will result in forming of condensation and this condensation can make the roof timbers rot and compromise the structural integrity of the entire roof. If there are no roof windows which is the easiest way to provide a loft ventilation, the next best option would be to follow the loft floor along to the point where the roof comes down to meet it. There should be a gap at this point, also referred to as the eaves, between the outside wall and the underside of the roof.
  • Measure your loft area. Take a measurement of the loft space in order to calculate the amount of insulation as well as the type you need. If you’re not sure, always get more that it’s required as skimming on the amount you use will only back fire in form of increased energy costs
  • Check for water pipes.

 

To get started, simply make sure all cracks and gaps in the ceiling are filled using a standard filler or decorator caulk. Once done, clean the gaps in the joists and even to the point of hovering all the dust up. Finally,check for the hazards that can cause you problems before laying the loft insulation.

In order to help you make the best informed decision possible, this post is going to address this issue and put you on the right path.

 

In truth, there’s no way to say exactly which type of insulation is the best as all types usually have a different purpose as well as usage. The insulation you choose for your home’s loft is be based largely on the how you’re going to make use of the space as well as any unique challenges you might face given the shape of your home’s loft. Below are some types of insulation to give you a better idea:

  • Blanket insulation. This is the most common type that comes in rolls of rock, glass or mineral fibre ( or foil-backed felt ). It normally the most affordable and also a good all-purpose insulation which is easy to fit although not suitable for the roof.
  • Loose-fill insulation. This type of insulation features a loose, lightweight material such as cork granules, cellulose fibre, mineral wool etc. It can either be incorporated as a top up or on its own. The primary drawback is it isn’t very secure and can also be very messy.
  • Sheet insulation. This is the best solution for the roof’s underside as it offers a highly effective insulation for your loft space and can also be decorated over. The drawback here is that it’s usually the most expensive type to purchase and install.
How long does it take to install insulation?

How long it takes to install insulation will depend on the size of your property. In general, loft and cavity wall insulation can be installed in a day or two. External wall insulation will usually take longer to install. The rep or installer will be able to advise you when quoting for the job how long this will be.

how much loft insulation do I need?

Over the years, more and more home and property owners are beginning to realize the huge benefits that can be derived from loft insulation being a worthwhile investment. It’s quite worrisome the way in which energy bills have soared over the past 10 years and loft insulation is a considerable affordable energy efficiency measure that can go a long way to help increase your home’s energy savings.

 

As far back as the 1980’s, the standard when it comes to insulation thickness was 25 mm to 50 mm which was, at the time, considered to be sufficient. However, building regulations have changed the norm that now states that a new build needs to possess 270 mm of insulation in the loft in order to achieve the required u-value of less than 0.16/m2k based on the standard rock wool or sheep wool insulation.

 

Generally with loft insulation, there’s a law of depreciating returns which implies that the first couple of insulation centimetres will save you many times the cost of the installation, however an extra layer or centimetre is going to add less value to the point where it’ll no longer be wise or worthwhile to add any further centimetre. Therefore, with cheaper energy prices 30 years back, that additional couple of centimetres was not just worthwhile, but with the recent alarming rises in costs of fuel, that additional £10 savings per year has all of sudden changed to £30 which makes it become a lot more attractive.

 

If you already have 270 mm of loft insulation, regardless of the material you’re looking to add you’re most likely not going to benefit from a top up. The cost of the materials and installation will definitely be too high for the couple of pounds it’ll save you per year.
