What sets Pierret joinery apart

Beyond the material, it's the versatility of a Belgian maker that handles PVC, aluminium and timber that makes the difference. The benchmarks specific to the brand, fitted by our teams.

Manufacturing Belgium

Joinery designed and made in Transinne, in the south of the country. A short supply chain: controlled lead times and parts available for the long haul, years after the install.

Materials 3 to choose from

PVC, aluminium and timber under one roof: you choose the material opening by opening, without switching maker or warranty logic. Genuine versatility.

Insulation (Uw) from ~0.9W/m²K

A high-performance profile paired with triple glazing lets the complete window reach an excellent level of insulation. High-efficiency double glazing remains the standard in renovation.

Warranty up to 10years

Manufacturer warranty on the profiles, the finish and the standard hardware, depending on the range and the material. wendows handles the follow-up if work is ever needed.

Finishes Made to measure

A wide choice of colours depending on the material: RAL foiling and wood effect on PVC, RAL lacquering on aluminium, stains and colours on timber, with two-tone possible.

Security Multi-point

Multi-point locking as standard, reinforcements suited to the material and optional anti-intrusion laminated glazing for the ground floor and easy access points.

Why choose Pierret for your windows?

When you replace your windows, you choose two things: a joinery brand and an installer. Pierret answers the first with a rare asset: PVC, aluminium and timber all made under one roof, in Transinne. In practice, you can mix materials from one opening to the next without changing maker or warranty.

That versatility is useful on a house where not every window faces the same constraints: affordable PVC for ordinary rooms, aluminium for a large living-room bay, timber to preserve the character of a period façade. A single maker as your point of contact for the lot.

"One maker for three materials means a single warranty and a single party responsible — from PVC to timber, seamlessly.

This is where our role as an authorised installer counts. We choose the right material and Pierret range for each opening, fit to the manufacturer's requirements and remain your single point of contact for the warranty, adjustments and after-sales. No buck-passing between the seller, the manufacturer and the fitter.

3

Three materials, one maker. PVC, aluminium and timber come out of the same Belgian workshop: you choose the material opening by opening, under one warranty and after-sales logic managed by wendows.

On budget, Pierret covers a wide spectrum since the price depends first on the material chosen: PVC stays the most affordable, while aluminium and timber move up the range. To place your project, start from our window prices & grants page, then ask for a costed quote, window by window.
