FAQ
At CRH, we often recommend PVC when you’re looking for excellent value for money without compromising on aesthetics. We notably work with Kömmerling, a well-known brand in the industry, to offer you reliable and durable solutions. And because impact matters too, we prioritize 100% recyclable products in our approach.
A good PVC frame, well selected and above all properly installed, significantly reduces heat loss: the goal is to eliminate the feeling of a “cold surface” and drafts near the windows. At CRH, we tailor the solution (profile + glazing) to maximize your energy savings and daily comfort.
Yes, PVC contributes to good acoustic insulation, but the final result largely depends on the glazing (thicknesses, asymmetry, acoustic laminated glass) and the quality of the seals/installation. Our role is to guide you toward the most effective combination based on your street, your floor level, and your exposure.
A quality PVC frame is designed to remain stable: at CRH, we prioritize solutions that resist heat (limiting warping) and retain their appearance against UV exposure (limiting discoloration). This is precisely a key point for joinery that is meant to last for years.
Maintenance is simple: in practice, a soft cloth with soapy water + a little white vinegar is sufficient in most cases. For more targeted cleaning (stubborn marks, specific finish), you can also use a product designed specifically for PVC.
Of course. We offer PVC window frames in a wide range of colors to match the style of your façade and your interior, whether you’re going for a discreet, contemporary, or more distinctive look. The idea is to maintain overall harmony (joinery, door, façade colors).
There is no “one-size-fits-all” glazing: it is chosen according to your priorities (insulation, noise reduction, security, orientation). CRH can offer you different types of glazing (including double glazing, safety glazing, and secondary glazing) and clearly explain the benefits of each option for your project.
Security is a combination of elements: hardware, locking points, locks/handles, and, if necessary, safety glazing. At CRH, we assess your configuration (ground floor, terrace access, old frame) to reinforce vulnerable points with the right options, without unnecessarily increasing the budget.
Yes. CRH also works on existing installations, whether they are PVC, aluminum, or wood, recent or older. Depending on the situation, we can inspect, adjust, replace a part (hardware, mechanism, etc.), or advise you on a replacement if it is the more durable solution.
We work in a structured way: an advisor analyzes your needs and takes the measurements, then a surveyor finalizes the technical measurements before manufacturing. Everything is made to measure, down to the millimeter, and installation is carried out in compliance with standards, with site protection and cleanup. After installation, you benefit from customer service, a follow-up inspection (intervention one year later upon simple request), and a standard 20-year warranty on the joinery.
