External Wall Insulation – Adhesive Fix

S and B External Walls

S and B EPS - external wall insulation system build up

Product Information

Around 35% of the energy used to heat and cool a building is lost via its external walls. External wall insulation is one of the quickest and most effective ways to improve energy efficiency, whilst at the same time transforming the external aesthetics of your home.

 

Expanded polystyrene boards can be incorporated into an external facade system to provide an efficient and cost-effective energy-saving solution. S and B EPS external wall insulation (also referred to as solid wall insulation) is an accepted and affordable way of adding thermal value to the outer face of external walls. Its versatility allows it to be used with a variety of finishes including plastic weatherboarding, cladding, tile hanging and reinforced render systems.

 

When used on the external face of a masonry wall, S and B external wall insulation maximises the natural thermal capacity of the wall and assists in the reduction of thermal fluctuations. Heating and air conditioning interior rooms consume a vast amount of energy, accounting for approximately 80% of a property’s total energy consumption. As a result, external wall insulation systems offer a highly effective solution to reducing the carbon footprint of a property as well as money expended on climate control.

 

S and B EPS offer various bespoke grades of polystyrene for thermal wall insulation; including grades such as S and B External Wall Insulation, S and B Lambdatherm® (a graphite-enhanced, low thermal value board), plus EPS 70E and EPS 200E – all containing a polymeric flame retardant additive. Thermal values range from 0.038 down to 0.030 W/mk depending on product and thickness. Selected grades of EPS raw material are also used for external wall applications to reduce any bowing and shrinkage of the EPS.

 

As well as local authorities and private social landlords having invested heavily in external wall insulation over recent years, there has been a huge surge in private householders taking advantage of this type of technology. This can be thanked in part to government-funded initiatives such as Green Deal and Green Homes Grant.

Radius Boards:

S and B radius boards are bespoke cut boards suited to turn square edge buildings into radius arches and radius arches into square edge buildings.

Recycling

Expanded Polystyrene (EPS) is 100% recyclable and any leftover waste can be disposed of via our ‘Waste Recycling Scheme’. Ask a member of our team for further details.

Advantages

  • Our EPS insulation boards are EWI system designer approved.
  • EPS is 98% air and is, therefore, an excellent thermal insulator.
  • The closed-cell structure of expanded polystyrene inhibits water absorption leaving it unaffected by the normal range of climatic conditions.
  • Faster, more efficient single leaf construction can be used, creating additional internal space with improved thermal performance.
  • EPS is lightweight, easy to cut and install.
  • S and B EPS is manufactured right here in the UK.
  • ETAG 004 compliant
  • A+ Green Guide rating
  • Expanded polystyrene is 100% recyclable
