FAQ

What is the U value?

The U value, that is the thermal insulation measure, plays an increasingly important role. The U value (heat transfer coefficient) describes how much thermal energy is transported through a building component with the size of 1 square metre.

To put it in simple terms:
The lower the U value, the better the insulation qualities of the window.

Ug = thermal insulation value of the glazing
Uf = thermal insulation value of the window frame
Uw = total thermal insulation value of the window

Windows made by our aluplast partners meet or exceed current and future energy efficiency guidelines as the German Energy Saving Ordinance (EnEV). You will never have to worry about saving energy! 

Terminology of window types

For the optimal use of the available space and in order to ensure adequate ventilation, the way of opening plays a crucial role. And, of course, the window type should also suit the building’s architecture. 

Tips for cleaning and maintenance for your new PVC window

How to care for your new PVC window frames

aluplast window profiles are made of weathering resistant high-quality PVC that requires low maintenance. Common soiling on the even, non-porous and hygienic surface caused by rain and dust can easily be removed with normal washing-up liquid.

Never use cleansing agents that can damage the surface as abrasives or chemicals (e.g. nitro diluter), benzene or similar agents. Clean your windows as required according to the type and level of soiling. 


How to care for the gaskets

The gaskets of your PVC window are made of high-quality weathering and ageing resistant rubber. Remember when cleaning your windows to also remove dust and soiling from the gasket. To durably conserve the gaskets’ elasticity and functionality apply special silicone oil every now and then. 


How to care for the hardware

To conserve your hardware’s functionality and movability you should lubricate it once in a while. Use oil to lubricate the movable parts of your hardware and non-corroding grease or petroleum jelly (Vaseline) for the locking points. By this means you can conserve your windows’ functionality. 


Initial cleaning of PVC windows after installation


Despite all the care taken by the craftsmen during installation, soiling as mortar splatters, fingerprints, wallpaper paste, colour splatters etc. may occur. Most soiling can easily be removed. Mortar and colour splatters generally can be removed with a semi-rigid putty knife. Carefully scrape the soiling off and wipe with a damp cloth.

Take care not to damage the surfaces as the small, sharp pebbles may leave scratches. Adhesive residues on the glass can carefully be removed with a sharp razor blade.
