Double Glazing
Our double glazing solutions combine Planitherm glass with argon gas and warm edge spacers to deliver superior thermal insulation. Available in uPVC and aluminium, these windows reduce energy bills while enhancing security through Mila hardware accredited by Secured by Design. Customisable in woodgrain, black, or grey finishes, they suit both heritage and contemporary properties. The multi-chambered profiles ensure durability and minimal maintenance, making them ideal for South Wales' variable climate.
Conservatories
We design and install year-round usable conservatories using high-performance uPVC frames and thermally efficient glazing. Options include Georgian, Victorian, and P-shaped designs with Yale locking systems as standard. Our bespoke solutions integrate seamlessly with existing architecture, offering natural light influx and improved energy efficiency. The structures are engineered to withstand Welsh weather while providing low-maintenance, secure living spaces that enhance property value.
Aluminium Windows
Our aluminium windows feature slimline profiles accommodating larger glass panes for maximum natural light. The thermally broken frames resist corrosion and require minimal maintenance, ideal for coastal areas. Available in a range of RAL colours, they incorporate internal glazing beads for enhanced security and Secured by Design accreditation. The multi-point locking systems ensure safety while the powder-coated finishes guarantee long-term aesthetic appeal.
Composite Doors
Manufactured in partnership with Door-Stop International, our composite doors combine uPVC durability with timber aesthetics. They feature Yale multi-point locking systems and Planitherm glass for A-rated energy efficiency. The GRP skins resist warping and fading, while the polyurethane core provides superior insulation. Available in various colours and panel designs, these doors offer enhanced security without compromising on style for both urban and rural properties.
Tiled Conservatory Roofs
As approved Supalite installers, we transform outdated conservatories with lightweight tiled roofs featuring 100mm insulation and breathable membranes. These systems reduce heat loss in winter and solar gain in summer, achieving U-values as low as 0.15W/mK. Available in 12 tile and 6 slate colours, they blend seamlessly with existing roofs while meeting building regulations. The 60-year lifespan and 10-year manufacturer guarantee ensure long-term value and comfort.
