Why PVC — and how it performs.

The benefits of PVC, the Everest Max system, and the full range of what we can build for you. Every unit is designed, measured, manufactured and installed by our own team.

What we build

A window for every home.

Casement windows & doors

The classic Everest Max system — elegant, airtight and highly insulating.

Sliding systems

Space-saving parallel and folding sliders that open wide to the view.

Pointed-arch window reflecting a courtyard

Arched & special shapes

Bespoke arches and custom geometries, crafted by hand.

Interior room with laminated wood-grain frames

Wood-laminated & coloured

The warmth of timber and bold solid tones, without the upkeep.

The system

Deceuninck Everest Max

A 60 mm, multi-chamber uPVC casement system — double-laminated for beauty and engineered for insulation.

4-chamber, 60 mm design

Multiple insulating air chambers within a 60 mm frame for superior thermal and acoustic performance.

TPE weldable gaskets (2 seals)

Corner-sealed gaskets create an airtight, watertight barrier around the whole sash.

Sloped drainage geometry

A unique profile design that speeds water away, protecting the frame and the wall.

Reinforced & versatile

Steel-reinforced for strength; supports casement, sliding, folding and outward-opening styles.

Wood-laminated Everest Max frames inside a room

The finish

Deceuninck Everest Max Double side-laminated

Durable lamination

Made to resist any type of heat and sun exposure.

Titanium chloride

Added to the mixture to make the colour laminate more durable.

Sustainability at heart

Sustainability is at the heart of what we do.

We create innovative products that contribute to sustainable living

Our windows, doors and building profiles guarantee superior insulation and maximum energy efficiency and enable you to reduce the environmental footprint of your home. As a result, you can enjoy greater living comfort and lower energy bills.
Our products are partly made from recycled base materials and are 100% recyclable. As a result, we need to use less new raw materials.
Our products last for a very long time and need little maintenance.

We produce sustainably

We set the standard for our industry, following Science Based Targets.
We invest in recycling technology and facilitate waste stream collection.
We minimise our carbon footprint and environmental impact as much as possible.

ISO certifications

Deceuninck Quality Certificates.

Sedofra fabricates on Deceuninck Everest Max. The profiles themselves are produced by Ege Profil under an IQNet-recognised integrated management system.

Quality

Every Deceuninck profile we fabricate is designed and produced under TS EN ISO 9001:2015 — a certified quality system from the plant to the frame.

Environment

TS EN ISO 14001:2015 holds production to an environmental standard, so the material in your windows is made with that duty built in.

Safety

TS ISO 45001 covers occupational health and safety across design, production, and delivery of the profiles we build with.

Colour & finish

Double-laminated, inside and out.

PVC/PMMA foils laminate colour and wood-grain to both faces of the profile — UV-stable, scratch-resistant and unmistakably premium. Available in the Basic (MX) and Solex (FX) colour ranges.
