The cellulose sold at big-box stores often has a lower density than professional-grade material. Expect 15-20% settling. If you install it to 15 cm, within two years it may be only 12 cm thick, reducing your R-value. Solution: Over-install by 20%.
When searching for affordable, eco-friendly thermal insulation, cellulose insulation (izolație din celuloză) frequently tops the list. In Romania, one of the first places DIY enthusiasts and homeowners check is Dedeman , the country’s largest home improvement retailer. But is the cellulose insulation sold at Dedeman a smart buy? Let’s break down the product, its performance, and what you need to know before heading to the hardware store. What Dedeman Offers Currently, Dedeman stocks cellulose insulation primarily under private labels or established brands like Termoizol or Baumit , usually in compressed bales. The most common product is loose-fill cellulose, designed for blowing into attics, floor joists, or hard-to-reach wall cavities.
If you are a green builder, cellulose beats fiberglass or mineral wool hands down. The product at Dedeman typically carries low VOC emissions and high recycled content.
In short: For a warm, quiet attic on a budget, izolația din celuloză de la Dedeman is a solid contender. Just don’t forget the blowing machine.
