Exterior Thermal Cladding a Victorian House

Exterior Insulation Cladding on older houses

For the majority of home-owners living in period homes it can be very difficult to picture what an outside thermal cladding system would look like. This is especially true if the walls are still the original brick and the new external wall insulation syustem is to be a coloured render finish.

As the above photo shows having just one outside wall thermally insulated can be visually attractive and can compliment the other walls, especially if the colour choice is well thought out.

Outside Insulation for Victorian, Edwardian & Georgian Homes

The vast majority of victorian and early edwardian homes are solid wall construction and so are perfect for the huge increases in energy efficiency and bill reductions that are a result of fitting exterior wall insulation.

Yet another option is to have the front facade thermally clad with a real brick finish either from a newly made brick slip tile or sourcing a reclaimed brick for a genuine reproduction finish.

What is the U value of my wall ?

Typical U values for solid wall houses

Whilst there is a great variety of construction materials and methods within the UK the following table is based around the most commonly found solid wall construction ie a 9 inch solid brick wall with 10mm of internal plaster .

The figures show the net U value achieved by the different external wall insulation materials that are used for thermally cladding the outside walls of our homes.

U Values Achieved

From an initial 2.05 to 2.10 U value the following can be attained:

9 inch solid brick & 10mm plaster

Depth                  EPS         Rockwool       Kingspan Phenolic

40mm                 0.63            0.62                    0.45

50mm                 0.54             0.53                    0.35

60mm                 0.47             0.46                   0.30

80mm                 0.38             0.37                    0.23

100mm               0.31              0.30                    0.19

Cement Render Insulation Value

The addition or presence of 25mm of external sand and cement render has virtually no insulation value at all and only reduces the above by 0.01.

Cavity, Blockwork & Timber Frame U values

THINC can also calculate insulation requirements for virtually every type of construction method and we welcome any enquiry for a specialist calculation that you may need.

Woolaway Homes Grants in Wales

Woolaway Concrete Homes

Not sure if this is going to be of any use but a blog watcher of ours has just told me that in Aberystwith there are some grants for external wall insulation for houses of concrete construction and especially those of the Woolaway style.

These are basically constructed of  solid concrete  panels and do not have a cavity to insulate so must rely on an exterior cladding system to bring the property up to the latest thermal standards.

Apparently these grants are part of an initiative in Wales to upgrade the most poorly insulated sections of older housing stocks. We can access partial grants for Woolaway owners but any extra subsidies are very welcome.

 

We do have a suitable external insulation system for Woolaway homes and so if you are looking to find out an idea of likely cost or simply want some more information please give us a call.

U Values – What do they tell me ?

U Value Improvements

Under the Building Regs Part L1B any new house being built or any existing house having work done on outside walls has to meet certain thermal efficiency standards.These standards are to ensure our homes are nice and warm in winter whilst also being energy efficient and cutting both carbon emissions and energy use.

Expressed in numerical terms the  U value measures the ability of a material to retain heat and the speed at which it allows heat to pass through it. The target for a new home is 0.25 U value and for an existing home undergoing renovations to a wall it is 0.3  if possible but no worse than 0.7.

Solid Wall Heat Loss

Solid Wall U Value

Most of the UK’s solid wall homes are constructed of two brick courses deep  totalling  9 inch thick  and have an average U value of 2.05 to 2.1 ie the new standards achieve around an 80% increase in thermal performance of the wall.

The Energy Saving Trust estimate an average 3 bed semi could save around £400 per year in heating bills if they took the correct insulation measures.

Home Energy Check

At this time of year in particular -  it is snowing quite heavily as I write this on 2nd December  – it can be very instructive and financially rewarding to take a step back and really think about ways in which you could save energy and money throughout your home.

Energy Cost Savings from Wall Insulation

CUTTING  HEATING BILLS

Whilst it can seem that every man and his dog are  shouting  from the rooftops about the value and efficiency of home insulation there is precious little detailed information on the pounds, shillings and pence that can actually be saved in particular from insulating cold solid walls.

Whilst every home uses their heating in different ways with varying temperature and timing settings it is possible to extrapolate certain guide line cost savings beased around authoritative bodies who publish independant figures based on serious scientific research.

HEATING COST REDUCTIONS – REALISTIC EXPECTATIONS


The following figures are based around a 5% annual price rise :

House    10yr Saving    Annual Saving at 10 yrs   20 year Saving        Annual Savings at 20 years

semi          £ 5,231       £ 620                           £ 13,841                        £1,061

det’d        £7,546            £ 977                         £ 20,006                      £1,516

Whilst these figures are purely a projection at 5% per annum increases in heating bills we believe they are very conservative especially when compared to increases in the last 4 years . In fact the above assumes about a 50% increase in energy costs in 10 years time when we have seen this size of increase in the last few years alone.

DON’T TAKE OUR WORD FOR IT !!

The above fuel savings are based around the UK average household  gas consumption of 20,500kw/h from OFGEM and the Energy Saving Trust’s average energy cost savings of £400 for a standard 3 bed semi using gas central heating that undertakes solid wall insulation

The Energy Saving Trust assess a 3 bed semi as having around 75 m2  to 80 m2 of net wall area and from our experience that is an accurate figure with a 3 bed detached having around 120 m2 of  net surface area . The heating bill savings are based on these figures.

REALITY CHECK

As for future price rises we do know that Ofgem have predicted a miniumum 20% rise by 2020 as a direct result of the  Energy Companies passing onto consumers the extra investment costs incurred to meet the legally binding Carbon Reduction targets and guarantees of future stable gas /oil supplies.

Throw into the mix the far greater costs of extracting oil from the new fields in the arctic and the extreme depths in the Gulf, along with increased demand from the likes of China and India,  and it is clear that the cost of oil and therefore gas will continue to climb.

Gas Price Increases

GAS PRICE RISES ANNOUNCED

The cynics amongst us will not be surprised to hear that within days of a sharp downturn in temperature, British Gas has announced a 7 % increase in its domestic gas prices.

In addition to this action from British Gas , Scottish & Southern also announced a 9.4% increase in gas prices as from 1st December. As they are the second largest gas supplier after British Gas it is a double whammy for consumers.

.

Temperature plummets as bills soar

Winter bites back

.

From the peak gas price – so far – of two years ago the wholesale gas price has dropped back by 40%  with a paltry 10% reduction in UK consumer prices !  Phil Bentley – CEO of British Gas – tried to explain that to counter the rise we , as consumers , should use less gas to keep warm as a result of more home insulation.

EXTERNAL SOLID WALL INSULATION

We are especially dismayed at the complete lack of any sizeable grants for people wishing to save energy by insulating their solid walls. The message seems to be if you have a cavity wall you are ok but if you live in one of the estimated 6 million “hard to heat ” solid wall homes then, TOUGH !

According to Mr Bentley his company alone has been obliged by law to invest £1 BILLION in Energy Efficiency measures to cut carbon emissions and as British Gas has around 50% of the UK market another £billion must be pledged by the other providers.

Interestingly he did not shy away from confirming this huge cost will be passed onto the consumers in higher bills despite any falls in wholesale gas prices in the future.

PROTEST !  PROTEST !

We would like to invite all our clients and blog followers and their families and friends to send an email or a letter to their local MP and ask them why the people most in need of help, those with the most energy efficient homes, receive the least amount of financial help ?

Please let us know what sort of reply , if any , that you get and we will publish them on the blog.

Thermal Camera Scan

INFRARED THERMAL CAMERA SCAN GLOWS IN THE DARK

Due to the latest scientific breakthroughs it is now possible to take an infra red picture scan of the walls, floors and roof of a house to highlight how much heat is being lost from the inside. In these days of ever increasing gas,oil and electricity bills it is more important than ever to ensure that your home is insulated to the highest standards possible.

thermal loss

Heat escaping through walls

In the above thermal image the blue areas are nice and cold whereas the yellow and red areas are leaking heat and costing extra in the form of increase heating bills.

PROVING EXTERNAL INSULATION WORKS

By taking a before and after thermal picture using our state of the art infra red thermal imaging camera we are able to demonstrate both the reduction in heat loss – ie an improved U value in the walls – and of course the reduction in carbon emissions as well.

External Wall Insulation Costs

HOW MUCH DOES SOLID WALL INSULATION COST?

 

costs of external insulationIt is very difficult to give precise costs for external wall insulation for several reasons. For starters there are 4 types of insulation board,30 varying insulation thicknesses and a dozen or so different texture finishes !

Throw in the fact that our homes vary in size and style and you can see why it is nigh on impossible to give a definitive cost without the measurements of a property.

 

 

WHAT ABOUT AVERAGE COSTS ?

 

As external insulation is relatively new in the UK most people have little idea as to the likely costs. We have therefore put together the following guide to what sort of external wall insulation costs you can expect to pay.


TYPICAL AVERAGE OUTSIDE  INSULATION COSTS

The following costs should be expected on standard sized houses for a basic insulation system using a coloured render and a 50mm insulation board:

mid terraced /semi bungalow £5000

3 bed semi/end terraced /detached bungalow   £10,000 +

3 bed detached house £13,000 +

4 bed detached house    £16,000 +

As far as we aware we are the only professional external solid wall insulation company that is prepared to list example costs and we would like to point out that costs can be more or less than the above
ball park figures.

However, we can often obtain a solid wall insulation grant rebate to help towards the costs and this can often make the wor

If the level of investment needed fits your budget then we will be delighted to hear from you.
