What does EWI look like?

At Be constructive ltd store we have been insu­lat­ing prop­er­ties big and small for the last 10 years. We use the EWI-Pro exter­nal solid wall insu­la­tion sys­tem from Germany to insu­late homes and busi­nesses across the cap­i­tal.


The insu­la­tion is nor­mally cov­ered with a sil­i­con sil­i­cate ren­der to pro­vide a fan­tas­tic clean fin­ish, but we can use brick slips to recre­ate the feel of a brick prop­erty if required.

Although we offer a white ren­der fin­ish as stan­dard, we can colour the ren­der to suit your require­ments, so if you have always dreamed of a canary yel­low prop­erty then now’s your chance!

Why Install External Wall Insulation?

Exter­nal solid wall insu­la­tion is fast becom­ing the most pop­u­lar prop­erty home improve­ment here in the UK. There are many rea­sons for this, which we will dis­cuss below.

Before we start though – just a brief reminder on what exactly external solid wall insulation is!

If you have a prop­erty built prior to 1930, the chances are that it will be com­prised of solid wall con­struc­tion. Put sim­ply, this means there is no cav­ity; the two skins of brick that make up the wall are built along­side one another. You can recog­nise a solid wall by the pres­ence of short half bricks in the wall itself (if you look from the out­side) – this is where a brick has been laid at 90 degrees to the wall, tying the two skins of brick together.

Instead of inject­ing the cav­ity (which you would do for newer cav­ity walls), insu­la­tion board is added to either the out­side or the inside of the prop­erty. In a way this is good, because you are not lim­ited by the size of cav­ity on how much insu­la­tion you can add to the wall, but it does have other impli­ca­tions like chang­ing the appear­ance of the out­side of the prop­erty (since the exter­nal wall insu­la­tion nor­mally gets ren­dered) or mak­ing rooms smaller if you attach the insu­la­tion on the inside of the prop­erty.

So why then would you look to insu­late your home with solid wall insu­la­tion?


The main rea­son for insu­lat­ing your home with solid wall insu­la­tion is to min­imise heat loss, thereby reduc­ing your heat­ing bill.

An easy way to com­pare a property’s heat loss per­for­mance is to look at the u-value, which gives a mea­sure of the ther­mal con­duc­tiv­ity / heat loss through a mate­r­ial. With­out insu­la­tion, solid wall prop­er­ties have a U-Value of around 2.1, com­pared with around 0.27 of an insu­lated one – this is a huge improve­ment. Now for those of you who don’t speak in U-val­ues (is may be just us!), lets con­sider the finan­cial sav­ings.

GDHIF and solid wall insulation

GDHIF and solid wall insulation

UPDATE: As of 30 March 2016, the gov­ern­ment has stopped fund­ing and the Green Deal Home Improve­ment Fund is closed to new appli­ca­tions. 

Solid wall insu­la­tion has become very pop­u­lar over the last cou­ple of years. This increase has been largely down to the recog­ni­tion that it has received, from the Gov­ern­ment, as a energy effi­ciency improve­ment wor­thy for the var­i­ous green schemes that they intro­duce.

One of these green schemes, which has proved to be par­tic­u­larly pop­u­lar is the GDHIF (Green Deal Home Improve­ment Fund) that launched for the first time in the sum­mer of 2014. This GDHIF scheme pro­vides a non-means tested grant to reward you for cer­tain energy improve­ments you install.

The Initial Green Deal Home Improvement Fund

Solid Wall Insu­la­tion was the the real focus of the GDHIF. Ini­tially, in the sum­mer of 2014, the avail­able grant was £6,000, but this ran out (there was an ini­tial £100m pot) just 6 weeks after it launched. The Gov­ern­ment noticed how pop­u­lar this was as a home improve­ment so in Decem­ber they released another £30m to help home­own­ers improve the energy effi­ciency of their homes.

The Second Phase of GDHIF – December 2014

This proved even more pop­u­lar and lasted just 30 hours! This was despite the fact that the grant was reduced to £4,000 per prop­erty (or if you had bought the house in the last 12 months – £4,500).

March 2015 – the Third branch of GDHIF money

In March 2015, it was announced at the EcoBuild show that there would be a fur­ther £70m made avail­able for home­own­ers to install solid wall insu­la­tion on their homes, so if you are inter­ested in insu­lat­ing your solid wall prop­erty – there has never been a bet­ter time!

The grant has once again been reduced though, but this time by just £250, tak­ing the total pay­ment down to £3,750. How­ever, bear­ing in mind it is still non-means tested – i.e. any­one with a solid wall prop­erty can access it pro­vided you insu­late 50% or more of avail­able exter­nal walls, it is still a fan­tas­tic offer.
