lime render

The long-awaited EWI Pro Heritage Range has finally arrived on our shelves! Lime materials have been proven over the centuries to be a reliable, safe building material that will withstand the test of time. In fact, the earliest known use of lime was 4000 years ago.

To celebrate the release of the EWI Pro Heritage Range, we’ve written about our top 5 reasons for why you should use the Heritage Lime Render system.

  1. Breathability

Lime is renowned for being porous and therefore vapour permeable. The effect of lime within renders is very positive; moisture can easily escape from the building fabric rather than remaining trapped behind within the walls (and wreaking havoc!). Breathability is essential for heritage buildings, as trapped moisture can seriously damage the ageing building structure. With Lime renders, water is absorbed into the render but instead of becoming trapped and causing the render to become ‘wet,’ the water is able to slowly evaporate out again.

  1. Environmentally Friendly

Lime is much more environmentally friendly than cement for a couple of reasons. Firstly because the lime is not ‘baked’ beforehand, there is a lesser amount of energy required for its production process.

  1. Strong but Light Adhesion

Lime binds lightly to substrates, so it’s a gentle material to use on a more fragile surface such as a Heritage building. Because lime has a small particle size, it’s a much more ‘sticky’ material; this means that it is able to bond to surfaces very easily and fill minute cracks to provide strong adhesion.

  1. Aesthetically Pleasing

Lime render has a fine texture and therefore offers a smooth render effect. The colour is a natural and traditional off-white shade – a highly aesthetically pleasing finish that is ideal for heritage properties.

  1. Lime is Flexible

Because lime has a very small particle size when compared to cement, it is a much more flexible material. When slight fluctuations within the building structure occur, lime is much more able to withstand this and is therefore much less likely to crack.
