External Insulation - Southern Green Homes Cork

External Insulation

You lose about 35% of your heat through your walls. SEAI gives up to €4000 Grants towards external insulation. This is one of the easiest ways to save money and make your home more efficient.

An un-insulated or poorly insulated external wall costs you money and harms the environment. On average, a home loses 30 – 40% of its heat through walls and even more if your home is not properly insulated. Even if you already have any wall insulation, you may still be losing heat if it’s damaged, less than is necessary or incorrectly installed. The growing popularity of External Wall Insulation Systems is based on the numerous advantages that this technology offers.

What kind of external insulation does Southern Green Homes use?

Southern Green Homes always uses the highest quality products on the market.  SempreTherm External Insulation is our product of choice for durability, warmth and style.


How SempreTherm External Insulation is applied:

SempreTherm External Insulation involves fixing insulation slabs to the outer surface of the wall with mushroom fixings. The insulation is then covered
with a special render to provide weather resistance. Fibreglass mesh is embedded into this render to provide strength and impact resistance completed with primer and a pre-coloured decorative acrylic, polysilicate or special brick-slip effect render.

SempreTherm External Insulation is NOT an expensive solution and additional problems (other than poor levels of insulation) suffered by some homes such as
driving rain penetration, moisture, mildew, poor air tightness or frost damage can be solved by SempreTherm External Wall Insulation System.
