Insulation Installer FAQs

Are there grants available for external wall insulation?

External wall insulation works to keep your home cosy and comfy while also helping to cut the energy bills. However with the great benefits also comes great costs, so it’s actually a logical decision to know whether there are grants out there which you’re eligible for to help you handle the cost of the external wall insulation.

There are grants available for external wall insulation, but rarely will you find one that covers the full installation cost. With the help of the government’s Energy Company Obligation (ECO) scheme, a couple of energy companies assist in making your home more energy efficient by offering grants or free insulation. In certain cases whereby you receive particular state benefits, you may as well qualify for a higher grant that’ll cover more of the insulation cost.

However, if your energy supplier doesn’t offer any grant, you need not worry as you can save as much on energy bill after installation. Here’s what insulation can help you save per year on energy bills:

• Floor insulation can help you save within a range of £30 to £75 each year.

• Cavity wall insulation can help you save about £85 to £280 a year.

• Loft Insulation (270mm) can help you save about £135 to £250 a year.

Generally, the amount you’ll be able to save on your energy bills depends mainly on the type and size of your property, as well as how energy efficient it already is without the insulation. In the long run, your external wall insulation will more than give you back your investment on the valuable project through your savings on energy bills. In other words, whether or not you’re eligible for a grant should never stop you from installing an external 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.
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 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.

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.

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.

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.
