ISOVER OPTIMA is a high performance renovation solution - for insulating older houses from the inside. Currently in Ireland there are a high number of homes with inadequate wall insulation, OPTIMA has been developed by insulation experts ISOVER to improve thermal performance, where outer facade or cavity wall insulation is not an option or not sufficient - OPTIMA offers a simple solution for the quarter of a million solid brick houses currently in Ireland, as well as many more cavity wall homes. It’s the 1st dry-lining system approved by the NSAI Agrément, as it is tested and approved to not only improve the thermal performance of a building, but unique in that it also takes care of potential moisture issues which arise from within the building and helps to reduce thermal bridges normally associated with drylining.

The average residential home can lose up to 30% heat loss through external walls (source SEAI) and OPTIMA Drylining system offers a simple solution.

ISOVER Ireland, part of the Saint-Gobain group are committed to comfortable living and climate protection and at the heart of our strategy is the promotion of best practice in renovation solutions, and driving building standards improvements. Therefore creating healthy buildings and living environments for residential home-owners - warmer, more comfortable homes and with reduced energy costs.
