Insulation Installer FAQs

how much is loft insulation?

More often than not, several homeowners fail to realize there’s so much value sitting right under their roof - the loft. When a loft is insulated, there are so many juicy benefits that can be derived. It can go a long way to save increase you energy savings and several more functions. Therefore, if you really wish to maximize the space under your home’s roof, you’d have to considering insulating it. So how much would it cost to have your loft insulated? Here, you’ll discover the cost of insulating your lofts so you that you can set a budget and start to plan.

 

The cost of insulating a loft is actually affordable for several individuals, however, this depends on a wide range of factors such as the size of the house as well as the type of insulation being installed. One significant factor is the insulating material that you choose to install. If done properly, you’d be able to prevent heat from escaping through the roof of the house which helps improve energy efficiency and ultimately, save you some money on heating bills.

 

If you’d prefer to make it a DIY project and you go for a blanket insulation it costs about £5 per m2. therefore, this will cost within the range of £100 to about £150 for a small home.

 

For a professional service, you’ll be provided with a quote for both the materials and labour. The amount will be based on the number of insulation required, the company hired, your location as well as the method selected. The price to purchase and install blanket insulation  would be between the range of £300 to £400 depending on the size of your home.

Will insulation save me money on my energy bills?

This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.

is cavity wall insulation a good idea?

Cavity wall insulation is basically the process of installing an insulating material between the two layers of brick making up a cavity wall, either as a retrofit measure or at the time of building. Obviously this is not a choice if you have solid wall, but for those who do possess a cavity wall, it represents an opportunity you may not want to let slide as it is a worthwhile and affordable wall insulation option. Clearly, cavity wall insulation will make your home or property feel warmer, but it also does come with a range of other benefits which is why we’d recommend installing it. In this post, we’re going to look at a number of reasons why having a cavity wall insulation done is a good idea.

  • It’s one of the cheapest energy saving measures that’s available. Not only is cavity wall insulation really effective, but it can also deliver great saving. In other words, it possesses a bigger payback compared to other options. When compared to other types of insulation, you can’t install cavity walls insulation by yourself, however it’s not so expensive to have it installed. The cost of the insulation will be determined by a number of factors such as your location, the company hired and more.
  • It reduces your energy bills. Cavity wall insulation can save you about £100 to £200 on a yearly basis on heating bills. In other words, this is usually able to pay for itself in as little as two years.
  • It reduces your carbon carbon footprint. If your home is heated with gas or electricity like several other homes, producing that energy involves burning fossil fuels which is known to be hazardous for the environment. If the heat generated is now allowed to escape through the walls, that means you’d have to use more to keep up your required temperature. Installation of cavity wall insulation in homes will enable a more efficient usage of the energy which will ultimately cut UK’s carbon usage.
How to get free external wall insulation?

This is a very great opportunity to not only get free external wall insulation, but also cut down your energy bills depending on the type of property you live in. Generally, to enjoy free external wall insulation you must at least be part of the group receiving one of the benefits listed below and also depends on the amount of money you earn. The benefits include:

• Income based jobseeker’s allowance (JSA)

• Income support

• Income-related employment and support allowance (ESA)

• Tax credits

• Pension credit guarantee credit.

• Universal credit.

There are also other important factors that determines if you can have a free insulation fitted on your property. These includes the place you reside, the carbon level of your home and according to some suppliers, the level of beneficial impact the insulation will have on your home. In order to have a free external wall insulation installed, you must either be the owner of your home or at least obtain the go ahead from your landlord before any external wall insulation activity can be made.

Good news is, if you fit the aforementioned criteria and you’ve already installed an external wall insulation, you just may be entitled to receive a refund for the good job done. However, to really find out if you’re eligible, we’d recommend you get in touch with your supplier directly. Also, the Energy Saving Trust (EST) can direct you to some organizations who can assist you in the determination of your eligibility.

As a home and property owner living in England, you can also check out the Each Home Counts Advice Website which is committed to giving impartial energy efficiency advice.

At the end of the day, if it turns out you happen to be ineligible for a free external wall insulation, you can still go ahead to contact a professional installer for a help at a competitive price to enjoy the several benefits that comes with home insulation.

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.

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.
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 cavity wall insulation lead to damp problems?

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.
