Outside Insulation On A Victorian Home

When it comes to external wall insulation there are at least several million Victorian period homes that present challenges in retro-fitting an exterior insulation system. Whilst cast iron soil pipes can be changed to allow thermal boards to be fitted behind, the greatest concern for the home-owner is in altering the aesthetics.

Complimentary Thermal Rendering

 

victorian external insulation Most people chose to buy a Victorian property precisely because of the apearance. In particular the large front windows and stone bay mullions contrasting against the red brick, are especially sought after along with some fancy brick detailing around doors and at the roofline.

Unfortunately these attractive homes do leak a lot of heat through the solid walls and can be very cold in winter and expensive to heat.

A good solution is to thermally clad the large gable side walls as these are the largest area of heat loss and are not that aesthetically pleasing in the first place.

If a neutral soft colour is used as the finished render coat the effect can actually enhance the look of the property whilst stopping any damp problems and of course reducing those heating bills.

Internal Insulation  for the Front Wall

It is still possible to maintain the original period frontage – and preserve the property’s value – whilst insulating internally to cut heat loss and lower running costs. The choices really are to dry line and plaster board the interior walls or, if this will affect dado or picture rails for instance, a better alternative may prove to be the latest 3mm thick thermal lining papers. These are incredibly effective especially when then painted using insulating paint additives which give a combined 40% reduction in heat loss and stop condensation damp as well.

Can EWI Stop Condensation ?

Trying to solve condensation damp is the second most popular reason, for householders  in solid wall homes, to consider having their outside walls thermally rendered or cladded . The most frequent question we are asked is how can external insulation  possibly cure damp condensation problems when it is adding yet another layer to their wet walls ?

How Exterior Insulation Stops Condensation

Solid wall insulation systems cure condensation by moving the dew point of a wall from the internal plaster surface to the outside of the external insulation boards surface ie the coldest part of the newly clad wall is the outside and not the inner sections.

Condensation – wet patches on the plaster leading to black mould or white “furring” – only occurs as a result of warm moist internal air hitting a cold surface such as when showering and seeing the mirror and windows steam up.

What is happening is that the water vapour in the air condenses from a gas to liquid  when it comes into contact with a surface whose temperature has dropped low enough to reach the “dew point ” . This is the point at which condensation thrives and the only real way to stop it is to increase the wall temperature sufficiently to allow the moisture to pass through the walls as vapour and escape to the outside.

What about Interstitial Sweating ?

This is when moisture becomes trapped in the inner core of the wall and cannot escape to the outside as quickly as it needs to and so builds up to a point where the vapour condenses to liquid and begins to wet the core of the wall. Unlike surface condensation this interstitial damp cannot be seen so is especially dangerous and harmfulto the structure of our homes.

All reputable  outside cladding and rendering systems have been tested by the Government funded British Board of Agrement for suitability of use on the UK’s solid wall homes and as part of the thorough testing regime they are checked to ensure they breathe more than sufficiently to avoid trapping moisture in the wall behind the thermal boards.

Better than Standard

The system renders that THINC Wethertex use al perform far in excess of the British Test Standard. The testing authorities use what they call a Dynamic Sweep Gas test to determine breathability and on their scale a material needs to score 25 or below to not be harmful to a home’s structure. Our thermal renders measured 12.8 which is classed as being highly breathable for a cladding system and way in excess of minium standards.

Energy Price Rise Announced

UK home-owners were dealt another bitter blow with the recent announcement by Scottish Energy of a whopping 19 % increase in our gas bills.

gas price rise makes insulation a must have

More Reason to Insulate

As sure as night follows day we will be hearing from the other utility companies that they also need to raise their prices and probably by a similar amount.

This latest rise means that gas and electricity prices have now risen by over 50% in the last two years and have doubled since 2006 !

Considering that demand is nowhere near its peak as yet due to the global recession it is a sobering thought that gas and electricity prices are only going to be headed in one direction in the years ahead.

If you want to reduce your heating costs and save thousands of pounds in the future there really has never been a better time to install solid wall insulation.

External Wall Insulation for Private Home-Owners

Whilst we have 36 years trading experience with outside insulation rendering in both the domestic and commercial sectors, we are especially keen to work with individual private home-owners to refurbish and retro fit the finest  external wall insulation systems available on the market and can design a bespoke system if so required.

We also welcome enquiries for new builds, social housing  and private extensions but the biggest gains from exterior insulation will be achieved by those people living in solid wall properties probably built before the 1930′s or the prefab style no fines concrete, Airey and  BISF steel top houses built in the 1950′s.

Green Deal or NO DEAL ?

The much trumpeted Green Deal is supposed to start in 2013 for those ” able to pay” home-owners who live in solid wall homes which are difficult to heat efficiently or affordably. The driving force is to try to lower carbon emissions and meet the UK’s self imposed carbon saving targets which are more stringent than our internationally agreed reductions. Unfortunately,unless drastically amended, the current proposals are doomed to failure.

No Financial Incentive = No Action

The proposed plans are based around a low interest loan from the private sector tied to the property and running for up to 25 years . The spin merchants state that the repayments are not paid by the home-owner but are fundedby the savings from lower heating useage and no annual repayments will be higher than the bill savings.

This sounds great until you realise the put upon home-owner will pay the same high heating costs as before and the actual bill savings go  to the lender to meet the loan repayments. There is no gain whatsoever for the homeowner so why put up with the work being done ? All that will happen is that a small number of home-owners who can fully fund the work will benefit as is the current staus quo.

Charge Against the Property

To try and make the bill savings cover the loan installments the proposals are to spread the loan over as many as 25 years and legally bind the home-owner to repaying the loan by putting a charge on the house itself. This has several major drawbacks that occur when the house changes hands or when any conversion or extensions are added.

House sales are very slow as it is, without forcing new owners to take on added loan debt from a Green Deal Loan. The new owners may want to remove the insulation and use an alternate energy source for example. Or they may decide to build an extension covering two external walls so why pay higher energy bills for something they are not benefitting from.

The Figures Don’t Add Up

The size of the loan is limited by the amount of annual bill savings spread over a maximum of 25 years so that all the repayment is covered by the “bill saving”. Unfortunately the use of the private sector who need to charge a commercial interest rate – albeit considerably less than the average loan rate – means that at best around half the cost will be covered by the loan with the rest from the home-owner. Remember as well there is no net financial gain for the home-owner.

Example Cost & Repayment

Average cost of External insulation for a 3 bed semi is £10,000

25 yr Loan at 7%pa total repaid £20,000

Total annual loan repayment £800

Energy Saving Trust bill savings pa £400

Net result is the loan will cover half the costs at best so clearly the current funding proposal is a definite non-starter .

What’s the Answer ?

A complete re-think is needed if the great British public are to be persuaded to take up external insulation in the vast numbers the Government believes necessary to hit our carbon reduction targets.

Any scheme needs to have a decent payback term and be coupled with genuine real- time reductions in heating bills or the initial cost should be subsidised by the Energy Companies with an increase in property values to reflect the lower running costs.

A good starting point would be to look at the hugely successful re-launch of solar roof panels that has been witnessed since the introduction of the Feed- In tariff. This scheme sees the home-owner get lower energy bills, re-coup their outlay in around 12.5 years and then get a pure profit of 8% a year for the next 12.5 years !

Properties Unsuitable for Thermal Cladding

Whilst in theory every solid wall home in the UK should have external thermal cladding fitted in order to cut heat loss and emissions it is not always practical nor effective. The style and external design of some 1920′s and 1930′s homes cannot be reasonably insulated from the outside as in the property below:

unsuitable for external thermal cladding

Hardly any external wall exposed

Amount of glazing wipes out any thermal gains from externally cladding properties such as this on the front elevation.

Better to insulate the side wall only to achieve any decent energy saving payback.

This also maintains the aesthetics and value of the period look, especially important for semi detached homes mirroring next door.

Tile Hung Wall Insulation

On a lot of 1970′s and 1980′s homes in particular the most common type of wall behind the tile hanging sections was either solid brick or solid blockwork with no cavity. When renewing worn tiles or replacing the tiles with a more modern looking weather board or render finish there is a great opportunity to externally insulate at the same time.

Tile Hanging Thermal Insulation

Once the tiles and retaining battens are removed the walls can be thermally clad with an external insulating board which is adhered with a powerful resin before being drilled and pinned to the wall. Once the cladding is secured firmly then the new tiles and battens or an alternative finish can be applied over the top of the boards.

Cost wise this is a very effective way of gaining money saving insulation as the work can be incorporated into the refurbishment and extras such as scaffolding will already be in place as well.

So, if you are thinking of changing the tiles or the appearance of your home please ask us for a quote to include some thermal outside insulation as part of the works.

Steel Frame Homes & External Insulation

Steel Framed houses are  becoming increasingly popular for the second time around due to quicker build times and this type of build is no longer the preserve of the industrial or agricultural sector. There are now wide choices in design style and external finishes that were not available in the 1950′s and 1960′s when steel or BISF homes were first being built.

Homes dating back to those pioneering days are often very cold in winter, hot in summer and can have condensation damp issues due to having no cavity to insulate and having walls that lack the thermal mass of other solid wall construction methods.

Outside Appearance

The older steel frame properties tended to have solid concrete shuttered walls or steel tongue and groove upper storeys whilst others had concrete or weatherboard panels as modular inserts between the vertical struts such as Airey or Woolaway homes.

 

 

 

External Thermal Cladding for Steel Frames

There is no problem  insulating the outside walls of such properties and the only difference to thermally cladding a more traditional build is in the preparation stage of the job.

Basically the only difference to a standard external wall insulation fitment is that a special profile frame is first fitted to the existing skeletal frame and the insulation boards are slid into the profile as opposed to being drilled and pinned directly into the underlying solid wall.

This is known as a “cavity rail” system as it essentially creates a 2omm air cavity between the frame and the cladding and prevents any damp corrosion from occurring as it ensures the system can breathe. Both the NHBC & Zurich recognise this system as being highly suited to steel frame properties as do the British Board of Agrement.

Finishes Available

Once the boards and profile are in place then the home-owner has the normal full range of decorative finishing options from coloured renders to textured renders, brick slips or weatherboards.
