More PVC & Timber Alternative from Artisan
If you love the timeless, character-rich aesthetic of traditional timber windows but want to avoid the endless cycle of sanding, painting, and high maintenance, the Evolution Storm range is the perfect solution for your home.
As a next-generation timber-alternative window system, Evolution is meticulously designed to emulate the authentic proportions, deep cills, and exquisite detailing of natural wood. However, because it is built using advanced, highly durable modern materials, it delivers industry-leading thermal efficiency, absolute security, and virtually zero maintenance.
At the core of the Evolution range is the celebrated Storm collection. Below, we explain the design journey and the key differences between the original Storm 1 and the advanced Storm 2 window systems.
When Evolution first launched the original Storm window (often referred to as Storm 1), it revolutionized the industry. It broke away from the look of standard, mass-produced uPVC by introducing authentic timber-style mechanical butt joints instead of ugly diagonal welds. It set a new benchmark for homeowners wanting to maintain the heritage charm of their properties.
Never content to stand still, Evolution developed the Storm 2—a complete re-engineering of the original design that pushes the boundaries of timber-alternative technology even further.
Here is how the two systems compare:
Storm 1: Features the pioneering, slim timber-alternative profile that successfully mimicked traditional wood proportions.
Storm 2: Takes sleekness to the next level. It features a unique 82mm deep frame system with enhanced, ultra-slender sightlines. This allowed for an even greater glazed area, flooding your home with more natural light while maintaining perfectly equal, balanced sightlines across all window sections.
Storm 1: Introduced the groundbreaking, handcrafted mechanical joints that gave the window its true "wood, not wood" look.
Storm 2: Perfects this craftsmanship. The Storm 2 incorporates even more intricate detailing, featuring fine ovolo internal moulding and enhanced wood-effect graining across the entire frame. The optional deep timber-proportioned cill is also beefed up on the Storm 2 to look completely indistinguishable from a traditional 19th-century wooden cill.
Storm 1: Offered excellent insulation that easily outperformed traditional single-glazed timber and standard double glazing.
Storm 2: Engineered to meet the strictest modern energy standards. The Storm 2 achieves an outstanding A+13 Window Energy Rating (WER) and an incredibly low 1.3 U-value as standard with 28mm double glazing. It stops heat loss in its tracks, keeping your home warm in the winter and cool in the summer.
Storm 1: Designed primarily around high-specification double glazing.
Storm 2: Offers maximum versatility. It is structurally optimized to easily accommodate high-performance triple glazing or specialized acoustic glass (which can reduce external noise by up to 30%)—upgrades that are structurally impossible to achieve in standard timber frames.
The Storm 1 & 2 represent the absolute pinnacle of stormproof window technology. Whether you live in a rustic cottage, a period Georgian manor, or a sleek contemporary home, the evolution Storm range is fully customisable.
Over 200 RAL Colours: Choose from 10 standard authentic wood-grain finishes or have them custom painted to match any colour scheme.
Heritage Hardware: Complete the look with hand-styled monkeytail handles, teardrop handles, or working peg-stays.
Uncompromising Security: Built with multi-point shootbolt locking systems, high-security hinges, and robust anti-intrusion claws to keep your family safe.
