What Sets Our Windows Apart?

At Sapphire Windows & Doors, we manufacture our own windows. Every window is made to measure and expertly fabricated by our master craftsmen using the latest precision machinery at our factory in Ammanford, Carmarthenshire. We don't buy an entry-level trade window and simply install it. We make our own, giving us greater control over the quality, performance, security and finish of every window we supply. Whether you're looking for replacement uPVC windows, energy-efficient windows, traditional windows or heritage-style windows, we can create a solution made specifically for your home.
White isn't your only option. Our windows are available in a huge choice of colours and finishes, making it easier to find a style that feels right for your property. For homes where timber character matters, our realistic woodgrain foil finishes include traditional shades such as Golden Oak and Rosewood. They give you the appearance of timber while retaining the energy efficiency, durability and low maintenance of modern uPVC. If woodgrain isn't for you, we offer a wide selection of contemporary colours, from subtle neutrals to stronger statement finishes.
Different homes need different windows. That's why we offer a choice of styles designed to complement both traditional and contemporary properties. Our Traditional Chamfered Windows have a clean, gently chamfered profile that provides a crisp, understated appearance. The smooth design is also easy to maintain, without unnecessary nooks and crannies where dirt can collect. For period properties and homeowners looking for authentic traditional character, our Heritage Flush Sash Windows are designed to replicate the appearance of traditional timber windows. Their flush finish and carefully considered proportions bring a subtle elegance to older properties while working equally well on contemporary homes.

Your windows should provide more than good looks and energy efficiency. They should help you feel secure in your own home. We use high-quality uPVC profiles and hardware to produce windows designed around security as well as performance. Our windows have attained BS 7950 and PAS 24 security standards, giving homeowners added reassurance when choosing replacement windows.
The frame matters. Our 70mm uPVC window profile provides an excellent balance of structural strength, thermal performance and appearance. The increased frame width allows us to use a narrower profile, helping to reduce the visible sightlines while maintaining excellent levels of strength and insulation. A 70mm frame also provides a practical advantage when replacing older windows. Its increased depth can help cover existing paint lines and mastic residue, creating a cleaner, more finished appearance around the new window.
Keeping your home warm and comfortable starts with reducing heat loss. Our 70mm frames and high-performance thermal glazing provide excellent insulation, with A-rated windows as standard. Built for the Welsh climate, our windows are tested for air permeability, water tightness and wind resistance to recognised European standards: Air Permeability: EN 1026 Water Tightness: EN 1027 Wind Resistance: EN 12211 From heavy rain to strong winds, Sapphire windows are made to perform.
At Sapphire, we believe good window design is about more than what you notice at first glance. That's why our white uPVC windows use neutral grey seals and gaskets rather than traditional black gaskets. The softer grey complements the white frame and helps preserve the clean, continuous lines of the window. It's a small detail, but it's typical of the way we approach every Sapphire window. Made to measure. Expertly manufactured in Ammanford. Designed for the way you live.
