ETRUM ROUND PLUS windows and balcony doors have all the advantages of the ETRUM PLUS system, enhanced by a characteristic encasement line which gives the products a traditional, timeless look.
The ETRUM ROUND PLUS system provides products with better insulation. The system of three seals creates a “dry chamber”, which protects the fittings from moisture and extends their life. An additional fin protects the casements from being pried and forcibly opened, ensuring peace of mind. There are also renovation frames available, which make installation easier by covering window opening imperfections from the inside.
