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.

how thick should loft insulation be?

Over the years there has been an increase in the recommended thickness of loft insulation by the government. Obviously, the reason behind this is pretty simply - the thicker the layer of your loft insulation the bigger your savings. The UK government is very keen to every house in the country to have loft insulation fitted where possible as it helps to minimize the heating demands of these properties. Households get to benefit from loft insulation in so many ways which includes reduced energy energy bills as well as having a home that stays at a more comfortable temperature for longer.

 

Generally, for the government energy efficiency is crucial as it implies that the highest demand ( which is usually the time of the day when gas or electricity use is at its peak ) reduces, since each building requires slightly less energy. Overall, that ultimately implies that new power plants don’t have to be built which is some nice cost savings for the government.

 

In the 1980’s, any thickness of loft insulation from 25 mm to 50 mm was considered the standard. But then, building regulations stated that homes should have as much as 100 mm of loft insulation. Over time, this gradually increased to 270mm for new builds and also recommended for other properties, although not essential. As a result of this, there’s always a need to check how much insulation you currently have in your loft before you decide to purchase more. You may discover that you already have something within the range of 20 mm to 200 mm up there and knowing this and the insulation values will assist in determining how much more you’ll need to purchase, if any at all. You should also note that some modern materials can offer the same thermal insulation whilst not being as thick.

Which type of insulation is best?

The best type of insulation for your property will depend on the type of walls and any insulation that’s already present. It’s usually a good idea to have some form of wall insulation as well as loft insulation, as this helps to prevent heat loss in both areas.

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.
