Dembava Progymnasium - Top Floor Ceiling Insulation
29 May 2026
Dembava Progymnasium, a public educational institution built in 1987 in Dembava, Lithuania, implemented top floor ceiling insulation covering the entire top floor of the building. The project was completed within just a few days, required no specialist expertise, and cost less than €500 — fully self-financed. No safety concerns or implementation challenges were encountered.

The impact has been directly felt, with the top floor noticeably warmer following the intervention. The institution expects the investment to pay off over a longer horizon of more than 3 years. The case is a straightforward example of how a low-cost, easy-to-implement insulation measure can deliver tangible comfort improvements in older public buildings — and the school would recommend the solution to others.
