ABAKUS bluENERGY GRETA PVC Windows — design inspired by concrete
GRETA are windows with an industrial design inspired by raw concrete, made of 100% recycled material. Salamander bluEvolution 82, Uw 0,76 W/m²K and installation by Pro-Plast in Białystok.

What makes bluENERGY GRETA windows special?
GRETA are windows with an industrial design inspired by raw concrete — the Greta colour is a concrete shade of grey with a slightly rough, natural texture. That is its main distinguishing feature versus smooth foils.
The second distinguishing feature is ecology: the GRETA profile is made of 100% recycled material. The construction is based on the Salamander bluEvolution 82 platform — 6-chamber, reinforced profiles with an 82 mm build depth.
What warmth and security does GRETA provide?
GRETA reaches Uw 0,76 W/m²K with a triple-glazed, 2-chamber unit at Ug 0,5 W/m²K. Despite its raw, concrete character, it is a fully energy-efficient window, well suited to Podlasie winters.
The sealing consists of two colour-matched stop gaskets and one central gasket, welded at the corners. Security is provided by Roto NX hardware, the anti-burglary Roto Line Secustik handle and burglar resistance up to the RC2 class.
