Heritage-listed window renovation in Bückeburg

12 wooden windows with muntins, true to the original. Coordinated with the heritage authority, proKlima-funded (up to €100/m²).

About this project

For this project in Bückeburg, several windows needed to be replaced — not only for energy efficiency, but also to match the architectural character of the existing building. VL-Innovativbau handled measurement, configuration to the occupants' preferences, and RAL-compliant installation. We use products from top German and Polish manufacturers — Aluplast, Veka, Salamander — and work strictly by RAL standards. Each opening was individually measured, the masonry repaired before mounting, and the joint sealed diffusion-open with interior foil and exterior compression tape. On request we also handle BAFA application paperwork and provide all evidence required for the subsidy.

Brief

Inhabited old building without a fence, rented apartments — appointments had to be coordinated with every tenant without delaying the heating season.

Solution

Installation in two stages over 3 weeks, 2-3 windows per apartment per day. Provisional frost protection with tarpaulin overnight. Tenants were guaranteed availability windows.
