Repairing badly installed EWI Insulation

Repairing insulation

Back in the sum­mer we got a call from a des­per­ate home­owner in Wim­ble­don who had been taken for a ride by their EWI Installer. The installer in ques­tion had sim­ply given up the install mid-works leav­ing the prop­erty in a ter­ri­ble con­di­tion.

This badly installed exter­nal wall insu­la­tion was even done under the government’s GDHIF scheme – it doesn’t pro­vide home­own­ers with a huge amount of con­fi­dence when works can be car­ried out to this poor stan­dard even under one of their own schemes!

Any­way – we were invited to come and take a look at the prop­erty and quote for the repairing insu­la­tion. It quickly became appar­ent we needed to start again – remov­ing the exist­ing insu­la­tion so we had a blank can­vas to start with. The main rea­son was that the EPS boards had not been cor­rectly attached to the walls. The EPS insu­la­tion boards are nor­mally bed­ded upon adhe­sive (some com­pa­nies use dry sys­tems with no adhe­sive but this is not rec­om­mended) which helps adhere them to the wall. This installer had decided to cut cor­ners and only apply adhe­sive to some of the boards – we were ner­vous that this wouldn’t last – so we made the deci­sion to remove every­thing and start again.

Render and insulated render what you need to know

Render and Insulated Render – what you need to know!

Insulated Render – what you need to know!

Is the ren­der on your home look­ing a lit­tle tired? Well there has never been a bet­ter time to re-ren­der your home! Tra­di­tion­ally ren­der was a sim­ple sand and cement, which works well how­ever it sim­ply doesn’t last.

The BBA approved ren­ders we use – known as thin coat ren­ders – are high per­for­mance, multi coat ren­der sys­tems. The key dif­fer­ence is that they have an addi­tional rein­force­ment layer. This rein­force­ment layer con­sists of a flex­i­ble fibre­glass mesh embed­ded within an adhe­sive. The ben­e­fit of this is that it moves with the build­ing, so the cracks that are com­mon place with the old sand and cement ren­ders sim­ply don’t form.

The thin coat ren­der, as the name sug­gests, is incred­i­bly thin. A 1mm gran­u­late ren­der should be applied on the wall in a 1mm thick layer – obvi­ously this is incred­i­bly thin but again it gives the ren­der a flex­i­bil­ity allow­ing it to adapt to changes in the build­ing through expan­sion and con­trac­tion (between the dif­fer­ent sea­sons) and also any slightly move­ments.

Don’t be fooled into think­ing that our ren­der sys­tems won’t last though because they are flex­i­ble! We offer a guar­an­tee of 10 years (although we can organ­ise a 25 year guar­an­tee for addi­tional cost through a third party). These sys­tems have been used across Europe in cli­mates far more diverse than we get here and they have lasted 30 years or more.

Our most pop­u­lar ren­der is our Sil­i­cone Sil­i­cate sys­tem – this is because it is not only breath­able, but it is also hydropho­bic mean­ing it repels water so this sys­tem can be con­sid­ered self-clean­ing. This ren­der is also avail­able in lots of dif­fer­ent gran­u­late sizes too to give dif­fer­ent fin­ishes depend­ing on your require­ments – it is avail­able in 1mm, 1.5mm, 2mm and 3mm. The Sil­i­cone Sil­i­cate ren­der is also avail­able in almost a lim­it­less num­ber of colours so you can match it to your favourite foot­ball team or what­ever else takes your fancy.

A new layer of ren­der on your home will really bring it to life – help­ing pro­tect the under­ly­ing brick­work and make it look as good as new how­ever if you are look­ing for some­thing a lit­tle bit more than just an aes­thetic improve­ment read on!
