Insulation Installer FAQs

how to insulate a loft roof?

Insulating your loft roof comes with a wide range of benefits. Not only do you get to maintain a comfortable temperature in your house for longer, but you’ll also get to cut down on your heating bills. If you wish to insulate your loft roof, you’ve come to the right place! This process can be very tedious and time consuming especially if you don’t what you’re doing or lack the required confidence to pull it off. It’s advisable to hire the services of a reputable professional who can guarantee the best results for help and also save you some time and money that can come from potentially costly errors.

 

Before you start rolling out, you’d have to make sure that all cracks, gaps and holes in the ceiling are filled with either a standard filler or decorators caulk. 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.
  • Lag pipes as you go in order to prevent walking over the insulation to get back to them.
  • Ensure that the loft is totally insulated
  • Insulate the hatch.
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.

Is loft insulation flammable?

When thinking about the right insulation material for your loft, some of the first few things that comes to mind is the various properties of that material as well as how good they fit with your home’s needs.naturally, you’d like to ensure that the insulation will be efficient enough to add to the overall energy efficiency of your home, however there are also other features that may not get as much attention but also happens to be equally important. As the primary function of an insulation is to blanket your house to offer a barrier against heat loss, going for an insulation material that’s also fireproof is crucial as loft insulation can burn. Although most insulation materials are fireproof, a myriad of problems can actually make your insulation burn.

 

For instance, fibreglass insulation is produced using glass combined with plastic polymers and is naturally resistant to fire. However, even at that you’d have to be careful with batts that are supported with foil or paper due to the fact that these materials can burn pretty quickly. Cellulose, on the other hand, is not fireproof and is required to be treated by other flame retardants in order to help reduce combustion. Some of the best insulation materials that are resistant to fire includes the following:

  • Fibre glass. This is made of glass that’s spun into fibres, then combined using plastic polymers. As a result, fiberglass insulation is naturally resistant to fire.
  • Mineral wool. Having a high melting temperature, this insulation material happens to be a great fit for thermal applications due to its superior fire resistant properties. In fact, mineral wool is still naturally non-combustible even if composed of recycled iron and steel by-products, or from actual mineral rock itself.
Does external wall insulation add value to your home?

The answer is yes! Houses whose external walls have been insulated are more valuable than their uninsulated counterparts. And not only does it add to the value of a home, but also significantly reduces the amount of electricity consumption. This is a major turn on for potential investors which implies a greater demand and ultimately, a higher price. The real estate market is a very dynamic one which can be hard to predict at any particular time. The frequent changes in price are usually down to factors beyond the owners’ control, but if you’re looking to put up your house for sale in the near future, it would be a wise decision to consider ways in which you can increase its value. While renovating each room can be on the expensive side, a great solution would be insulate the external walls.

An insulated house is one that is well secured against the harmful impact of extremely high or low temperature, humidity and other atmospheric factors. Hence, the reason why a house with external wall insulation has a greater value which you would not want to miss out on. What’s more? You’ll get a great thermal insulation with the top notch materials like foamed polystyrene, high quality renders, mineral wool or polyurethane.

With an external wall insulation, you know the transaction will always be favourable on both ends. You get to smile to the bank, while the buyer also gets to enjoy great value for every penny spent. To employ the services of a reliable external wall insulation expert, simply conduct an in depth research from family and friends, online and other sources. Go through their online reviews and ask questions to become more familiar with the process and its value-adding potentials.

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.

How to fit external insulation?

With the title of this blog, do not be deceived into thinking the purpose is to encourage you to install an external insulation by yourself. Even as a competent DIYer, it’s not advisable to buy a couple of materials and start slapping it into the wall hoping for the best outcome. External insulation is by no means a DIY job and without the proper training and experience, it can easily turn out disastrous resulting in loss of time, effort and money in such a valuable project. This blog, however, will give you a great insight on how the installation process works and help maximize knowledge ensuring you do not spend more than necessary.

External Insulation Installation

lRender Test

• This is done to ensure the existing render is good enough for insulation support.

• If positive, the insulation can be applied directly onto it.

• If negative, ensure removal of the old render before fitting the insulation.

lPipework Adjustment & Removal

• Remove all pipework prior to insulation fitting

• Install temporary downpipes to ensure water is not wasted and everything continue to function normally during the insulation fitting process.

lWindow Protection

• Protect the window with a protective layer or film.

lStarter Track Fitting

• Determine level you want the insulation to start (height).

• Fit the aluminium start track or carrier tray at the identified level.

lInsulation Boards Fitting

• Apply a layer of adhesive to the board and glue them to the wall in a staggered pattern.

• Cut to fit round all obstructions and windows.

• File off the edge of the board where necessary using a rasp upon successful fitting of the boards

lMechanical Fixing Inclusion

• Hammer around 10 fixings per square metre into the board.

• This is to secure the insulation boards.

lBeading Fitting

• Add corner beads and stop beads to ensure the insulation is secure and to prevent it from making contact with other materials.

lReinforcing Mesh & Render Addition

• Apply two layers of strengthening properties and between the two layers of render, include a fibre glass mesh.

lPrimer Application

• Paint on the primer

lFinal Render Application

• Choose your most preferred texture and colour as this will be the last coating of the installation process.

lPipework Re-installation

• Re-install all detached pipework at the start of the installation process.

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.
