Case Study - SPS Timber Windows

SPS Timber Windows, a specialist in bespoke Accoya wood box sash and casement windows, was facing mounting production pressure as demand for its BFRC A-rated products outpaced the capacity of its existing machinery. After extensive research, the company selected the Soukup Crafter CNC Window Machining Centre, supplied by IWM, which cut production time by more than half and freed up valuable workshop space.

Founded in 1998 by Simon Walker, SPS Timber Windows had built a strong reputation for award-winning, BFRC A-rated Accoya wood box sash and casement windows, earning endorsements from Which?, FENSA, BFRC, and the BWF. As demand for their bespoke timber windows and doors grew significantly, the workshop's reliance on traditional spindle moulders and tenoners became a bottleneck. These conventional machines were no longer able to deliver the throughput needed to meet order volumes without placing unsustainable pressure on the production team and floorspace.

Following extensive research into available options, SPS selected the Soukup Crafter CNC Window Machining Centre, specified through IWM. The Crafter is designed specifically for the demands of bespoke timber window and door production, consolidating operations that would previously have required multiple separate machines. For a workshop producing high-specification Accoya windows to exacting tolerances, the Crafter offered the combination of precision, flexibility, and a compact footprint that SPS required.

The impact on production was immediate and significant. Workshop manager Eric Frimpong confirmed that the Crafter delivered a meaningful increase in production capacity alongside a reduction in the floorspace required — a notable benefit in a busy joinery environment. Simon Walker reported that the machine exceeded expectations, with production now achievable in less than half the time previously required. Walker also confirmed that future machinery investments would continue to be made through IWM.
