INSULEX  was founded in 1994, originally as a specialist contractor, and then transitioned through the years to specialise in various types of Insulation and became known as the go-to company in Munster for Insulation and preventing heat loss in the home.

Fast forward to recent years and now Insulex is among a select few companies in Ireland that are registered and approved by the SEAI as a ONE STOP SHOP provider for all your Home Energy Upgrade requirements.

Managing Director Martin Mc Carthy, and his team at Insulex, based in Ballinadee, Bandon offer complete energy upgrades to any home no matter how old.

“ We specialise in taking old, cold homes which can have a BER rating of F or even G and transforming them into warm, cosy, energy-efficient homes with a focus on renewable energy systems.

The most important thing for us is to prioritise what our clients want. So we like to spend time with our clients going through their needs, wants, and desires and working with those specifics and their budget to create a plan that works for them.

Every home and every family is different, so for us, it is exciting to be able to deliver quality information and customised options to ensure our clients can make informed decisions about their homes.’

” Our ultimate goal is to deliver a warm, energy-efficient, cost-effective, and future-proofed home.”
