You can also clean between between the gaps in the joists thoroughly. And finally, check for hazards that can cause you problems before getting stated.

  • Remember to leave ventilation gaps as you start from the eaves. Then work towards the loft’s centre, starting from the point furthest from the hatch.
  • Lay the first layer between the joists which should be 100 mm and then the subsequent layer should be 170 mm to make it up to the recommended 270 mm.
  • Carry the electric cables above the insulation and work around visible light fittings.
  • Cut the roll in the centre of the floor when rolling out from the eaves on both sides with the help of a craft knife. Ensure that there are no gaps between the insulation and the joists’ edges.

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.

does loft insulation cause condensation?

The short and simple answer to this question is yes, loft insulation does cause condensation. Over the years, problems with condensation in loft spaces have become increasingly common. While this may not be harmful in anyway, when the condensation becomes excessive it can lead to more serious issues taking root in your loft like wet rot, dry rot as well as black spot mould. Generally, the best thing to do if you’re concerned about the condensation in your loft space and that it may rapidly become a bigger problem is to get in touch with a damp specialist as soon as possible.

 

Even though insulating your loft space comes with a wide array of benefits like making the top floor rooms warmer, it’s however comes at the cost of making your loft or room space cooler. Condensation in lofts take place primarily due to the humid air making its way through insulation or other gaps into the loft space and touching a cooler surface which in turn results in beads of moisture on the timbers, lintels as well as the underside of the roof. This is why its always a great idea make use of thermal insulation with a vapour barrier that’s installed on the warmer side of the insulating material.

 

Condensation in loft is caused by excess moisture in the air and lack of adequate air ventilation. Here are some top reasons that gives rise to this in the loft:

  • Extra insulation has been installed in the loft leading to a restriction on the natural air circulation in the property.
  • When the storage boxes or other items that has been stockpiled in the loft blocks the roof vents.
  • The release of steam and moist air into the loft space by hot water tanks.

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.

Insulating a cavity wall should not affect the damp proofing of the wall. All insulation approved for use in cavity walls has been tested to ensure that it does not allow damp to pass through the wall. Some walls which receive a lot of wind driven rain are unsuitable for cavity wall insulation.
