Lime For Contemporary Construction

Slide 2

The benefits of using lime to create a vapour open construction are well known for historic solid walled buildings, however its use in modern construction is not so well documented.

Slide 4

The most common argument for using a lime mortar in modern buildings is for its green credentials. There is an immediate reduction in carbon at the production stage because lime is burnt at lower temperatures than cements. Lime mortars also set through carbonation, which is the reabsorption of CO2 and this reabsorption further reduces the embodied energy of the mortar.

Slide 7

When compared to cement based mortars, lime can offer a significant reduction in carbon, however the benefits do not stop there. Modern buildings are designed to prevent water ingress through the use of a cavity. Masonry is porous and will draw water and moisture into the wall from internal and external elements, the cavity serves to drain this away and prevent it from being built up.

Slide 10

However, a cavity alone cannot protect a building entirely from water related issues. It has been estimated that up to 75% of building failures are due to water, with the most common causes of failure being water penetration and interstitial condensation. Water related issue do not always result in failure, they can also impact the thermal performance of the structure and the occupier’s health.

Slide 13

The Cornerstone Newbuild Mortar range offers a variety breathable mortars for both internal and external use in modern construction. Materials Overview: A blend of specially selected sands, St Astier NHL, specialist cements and working aids The Cornerstone Newbuild range offers a system that can be applied to render carriers (timber frame), block, brick and stone as a render. It can also be used as a building and pointing mortar Vapour open, allowing moisture to escape the surface

Slide 14

Highly flexible, can accommodate movement Highly workable, with all of the benefits of lime Can accommodate heat and regulates humidity Reduced risk of shrinkage and cracking Batch blended for consistency Colour is derived from the sand, so no pigment additions. No chemical additions (such as silicone) With up to half the embodied carbon of conventional cement based mortars. 1 tonne of Cornerstone New build mortar can absorb 30kg of CO2 – equivalent to the amount of CO2 absorbed by a young tree in 3 years.
