Double Glazing — Fenwick

The benefits of uPVC windows extend to our extensive range of uPVC doors, recyclable, energy-efficient and more budget-friendly than composite or wooden doors. This often leaves more room for elegant designs or upgrades to triple or acoustic glazing, with extensive hardware and finish options.

Exterior French doors create a wide, elegant entrance that maximises airflow and access to gardens or balconies. A-rated with low-U-value double or triple-glazing, they combine excellent thermal performance and security, perfect for terraces, balconies and garden entrances.

Bifold doors open up your living space with a seamless indoor-outdoor flow. Large glass panels sit within sturdy aluminium frames that fold and stack neatly aside, allowing wider openings than sliding doors, ideal for kitchens, garden rooms and balconies, with double or triple glazing for year-round comfort. 

Triple glazing uses three panes and two air gaps to cut heat loss by up to 136% compared to single glazing, ideal for large bay windows common in Fenwick homes. At 42-44mm thick with an ‘A’ energy efficiency rating, it offers better noise reduction and security, and can be fitted to most uPVC and composite units except patio doors.

Our double-glazed aluminium windows feature reinforced, corrosion-resistant frames with slim sightlines for more natural light and a wide choice of colours and finishes. Multi-point locking and thermally efficient polyamide breaks boost security and cut energy bills, a smart long-term investment for any Fenwick property.
