In today's society, we're all becoming increasingly aware of the importance of being more energy efficient, watching our carbon footprint and generally taking care of the planet. This is why so many of us are looking to improve our house and wall insulation. You are sure to save money with low insulation installation costs and reduced heating bills. We offer such a fantastic variety of insulation services for internal walls, external walls, attics, roofs or whatever your needs are. Our experienced and dedicated staff can cater for and supply to every sort of insulation need that you may have.

External wall insulation

External wall insulation provides exterior walls with insulation, finished surface and waterproofing in an integrated composite system. Because walls are areas where the house heat loss is one of the greatest reaching up to 35% of the overall, if they are not properly insulated, this is one of the most effective measures getting your home warmer and greener.

Insulating from the outside has a clear advantage over conventional insulation techniques like dry-lining wall insulation. By insulating from the outside and cutting thermal bridges, the entire building structure is protected from the cold and wet weather, which is not the case with internal insulation. These type of insulation also has the biggest advantage for the homeowners applying for the Home Energy Saving Grants. For this measure the grant is the highest. 

Homeowners availing of any external insulation grants under the Home Energy Savings scheme should aim to achieve a U-value of 0.27 W/m K or better (i.e. lower). Only NSAI and SEAI External Insulation certified installers can do the job which would be alligible for the grants.INGLOTHERM LTD has NSAI Certificate  for External Wall Insulation and SEAI registration for External Wall Insulation with Contractor ID 17081

External insulation involves fixing insulation materials such as mineral wool or expanded polystyrene slabs to the outer surface of the wall. This insulation is covered with a special cement-based render to provide weather resistance. A steel or fibreglass mesh is embedded in this render to provide strength and impact resistance. A thin layer of insulation may be applied around the edges of window and door openings to minimise thermal bridging. The technology is well-established in northern Europe, where it has been in use for many years, but is not yet widely used in Ireland. However after introducing Home Energy Saving Grants this technology has been very quickly accommodated by the external insulation contractors.

Particularly Greinplast External Wall Insulation System with high quality graphite enhanced polystyrene from Thermotech Ltd. are highly recommended by INGLOTHERM LTD for external wall insulation. This is also the most economic in comparison with other technologies like mineral wool or fibre glass.
