Double Glazed Windows
Our A+ rated double-glazed windows improve home insulation and reduce energy bills by up to 20%. Using Liniar's lead-free, recyclable uPVC frames with multi-point locking systems, installations include protective measures to prevent property damage. Each window comes with a 10-year warranty and energy certificates, enhancing property value while maintaining aesthetic appeal through white or wood-effect finishes.
Composite Security Doors
Manufactured with impact-resistant GRP skins and polyurethane insulation, these doors offer nine times better thermal efficiency than timber equivalents. The advanced glazing system and multi-point locking meet Secured by Design standards, available in 14 glazed styles. Each installation includes a 10-year warranty, combining durability with low maintenance requirements through pre-pigmented finishes.
Conservatories
As approved Aztec Conservatories installers, we create custom extensions using thermally efficient uPVC frameworks. Options include various roof styles and glazing configurations, designed for year-round use with low maintenance requirements. All conservatories feature 10-year warranties and can be matched to existing property aesthetics through multiple colour and finish choices.
Bi-Fold Doors
Origin Global's aluminium bi-fold doors combine ecological credentials with advanced security features. Their slim sightlines maximise natural light while maintaining thermal efficiency through insulated frames. Available in 500+ colour options with finger-safe gaskets, installations include electric automation options and 20-year manufacturer guarantees covering both materials and mechanical components.
Garage Doors
Supplied from premium brands including Hormann and Garador, our garage doors feature reinforced steel frames with multi-point locking systems. Available in sectional, roller, and up-and-over styles with woodgrain finishes, they include 10-year warranties and optional automation. Insulated models provide enhanced thermal performance while maintaining durability against North Wales' weather conditions.
