Ecological Building Systems

Show business description

Our ethos at Ecological Building Systems is to achieve 'Better Building' by adopting a 'Fabric First' approach to design, with the use of more natural materials to optimise building performance and durability.  We deliver quality products with full technical support.

Ecological Building Systems was set up in Athboy, County Meath, Ireland in 2000, the UK division was established in 2007 and is based near Carlisle in Cumbria.  Ecological's parent company is MacCann & Byrne, a family owned company steeped in history having been established on the same premises in Athboy since 1906.

Product Range

Our focus is to deliver building products that achieve 'diffusion open' buildings.  Forming strong relationships and networks with our European partners, the first products that Ecological imported was the Pro Clima range of airtight and windtight building products.  The company then went on to establish itself as sole importers of some of the highest performing, quality natural insulations available on the market.

Our Service

At Ecological we back up our high-quality goods with a technical service second to none. Our dedicated teams in Ireland and the UK support specifiers, home owners and contractors to achieve their goals to build healthy, durable constructions.

Our Distribution

As sole importers of the building products we offer, we endeavour to stock and efficiently supply as broad a range as possible from our own warehousing.  We have extensive warehouse and distribution channels in both Ireland and the UK to ensure that our supply chain is serviced. 

For our Pro Clima range of airtightness and wind tightness products, we supply through a network of stockists, who have been trained by ourselves and are fully supported by our backup technical support.

Our Commitment

We are not a large corporate team at Ecological and although we are small, we do always strive to offer the best possible service to our customers.  Where possible we try to respond within 24 hours, even if it is to acknowledge receipt of your technical request or query.  We will ship our goods as quickly, safely and efficiently as possible and endeavour to meet your deadlines.
