ECO Plano - High-insulation Wood-Aluminium Profile

The elegant Composite System in flush-mounted design

The Eco System is a high-insulation wood-aluminium profile providing optimum thermal insulation. When triple glazing is incorporated then insulation values can be attained that are suitable for passive houses. The special polyurethane insulating wedge ensures that the aluminium cover does not come into direct contact with the wood. This ensures that the vapour diffusion is maintained completely.

RAL Seal of approval for the Aluminium Casing from "Stemeseder Alto Nova"

The RAL-approved aluminium casing means that you can expect the highest possible quality. This is constantly being monitored and tested by independent outside authorities. So you as the consumer or end-user can be sure that the windows and doors you receive are of excellent quality.

By using welded corner units, the corners are not warping even under heavy strain. This has an attractive look while being water tight at the same time. Aluminium as a working material is very weather resistant and can be supplied in virtually any of the RAL colours. Thus you have an extremely wide colour selection and a maintenance-free system.

High Quality hydro-planed Surfaces and special Wood-Aluminium Colours for Indoors

This new and innovative method of machine planing means that the wood surfaces are especially smooth and of high quality. The wood fibres on the top surface are not only cut off but pressed flat leaving the pores open.

The primer thereby penetrates deeply and permanently into the wood protecting it. Hence, you have an attractive and high quality window for a long time to come.
