External wall insulation equals thermal comfort & internal well-being
Baumit research has identified three key principles to consider when building a sustainable home: thermal insulation, external-wall materials, and indoor air humidity. Good thermal insulation not only makes a significant contribution to a building’s energy efficiency, it keeps walls warm in winter and pleasantly cool during summer. This temperate quality is essential to occupants’ long-term comfort and wellbeing. The purity of indoor air is also crucial to our health; particularly when it’s considered we inhale up to 13.5kg of interior air, compared to 1.5kg of fresh air, per day.
Desirable interior
The most effective method for creating a healthy living space is to optimally insulate the façade - the better the insulation, the more comfortable the space will be. Quality External Wall Insulation (EWI) can help achieve this desirable level of interior comfort. It’s a solution that is particularly effective in multioccupancy properties.
Through everyday living, residents create water vapour. Baths, washing, cooking, all creates steam. Now, consider how much vapour is generated in a multi-occupancy building containing, say, 150 tenants. All that vapour will pass through the building’s elements. This can lead to increased air humidity, condensation and damp, which once inside a property, can take a lot of time and expense to remove. Therefore, an EWI solution will limit future maintenance and unforeseen expenditure.
Robust frontage
Applying a non-breathable renovation system to a building causes what might be referred to as the “plastic bag effect” - walls can become cloaked in condensation from non-escaping vapour. To create a breathable outer layer for buildings an EWI system topped with a silicon-based finish render, such
as Baumit’s SilikonTop, is preferable. Water-repellent, stain and weather resistant, the system provides a robust white or coloured façade, whilst optimising occupants’ living environment. Baumit EWI systems comprise six, high-quality vapour permeable components. Choose from a range of insulation boards and renders to complement specific requirements. When applied as part of a new-build or refurbishment project, each component helps increase a structure’s ‘breathability’ to collectively offer outstanding levels of insulation.
retaining heat; our buildings are also retaining moisture - which creates problems of its own. Allowing buildings to breathe on the outside will not only ensure those living on the inside are living a lot happier and healthier; a good thermal insulation can help reduce household heating costs by up to 50%, which is a great comfort provision.
There can be no doubt the government is right to address the alarming statistic provided by the Green Building Council report which stated 25 million homes across Britain will not meet insulation standards by 2050. However, air tightness can mean as well as
