Why Use Lime? 

Lime has been used as a building material for centuries thanks to its durability and visual impact. 
 
Many of Britain’s historic buildings were constructed using lime-based products and this has contributed to their longevity and aesthetic qualities. This knowledge has led many of today’s builders to rediscover the benefit and pleasure of using lime-based materials. 
 
Lime is considered to be a superior building material because it allows buildings to breathe and move, reducing the risk of trapped moisture and preventing damage to the building fabric. Lime-based products are easy to work with, remaining smooth and malleable, and they give a beautiful finish that develops a rich patina over time. Lime also has several ecological benefits, using less embodied energy than cement with the benefit that it can be produced on a small scale. 
 
 
 

Benefits of Lime  

 
Breathable 
 
Heritage limes are breathable which is an essential quality for solid masonry walls, which are found in most period buildings. 
 
 
Elastic 
 
No expansion joints, minimal shrinkage and cracking. 
 
 
Healthy 
 
A breathable structure is also an important quality for internal living conditions
 
 
Workable 
 
 
Free lime content gives good workability. 
 
Natural 
 
 
Heritage Limes are natural products.  
They contain no additives and are not blended. 
 
 
Recyclable 
 
 
Building materials used with Heritage Limes can be recovered and reused. 
 
Resistant 
 
 
Lime is resistant to salts, bacteria and vegetable growth. 
The absence of gypsum and cement ensures sulphate attack and salt re-actions are impossible. 
 
 
Green 
 
 
Lime re-absorbs CO2 during curing. 
 
Flexible 
 
 
Compressive strength is gained gradually, allowing for movement. 
 
Cost Effective 
 
 
Low bulk density means good economy as sold by weight but used by volume. 

Frequently Asked Questions  

what is lime? 

Lime is derived from rocks and minerals that are composed primarily of calcium carbonate, such as limestone. When limestone is burnt, it produces quicklime, the addition of water turns this into slaked lime, and the resulting putty or powder is mixed with sand to make lime mortars, renders and plasters. 
 
 

what are the benefits of lime compared with cement? 

Lime is valued for its workability, remaining smooth and mouldable, even against porous materials such as brick, limestone and sandstone. It is extremely breathable, allowing moisture and damp to evaporate, can tolerate movement, and is strong enough to stand up to harsh weather. It also produces a beautiful finish that improves over time. Cement, on the other hand, sets rigid and has low moisture permeability which means it is not compatible with soft and porous materials. It is thought that cement may even damage such materials. Cement-based products do not have the same aesthetic qualities as lime mortars, renders and plasters which is why lime is becoming an increasingly popular choice for today's builders. 
 
 

can i incorporate lime products into my new build home? 

The simple answer is yes. Lime is the ideal building material for all types of building work, not just conservation and period renovation. The choice of lime for your new build home will ensure its longevity and your home will also benefit from the aesthetic qualities of lime, which only improve with time.
