Energy‑Efficient Window Styles for Southwest Homes
Casement Windows
A classic, versatile choice offering excellent ventilation and security. Available in multiple opening options, colours and finishes — including 17 foil colour options from stock.

Tilt & Turn Windows
Dual‑function openings allow secure ventilation with the tilt option and full inward opening for easy cleaning or fire‑escape suitability. Perfect for upper floors and hard‑to‑reach locations.


Flush Sash Windows

Bay Windows
Bay windows create extra interior space, enhance natural light and deliver beautiful architectural impact. Available in multiple styles and frame colours, they can transform a room while providing excellent thermal performance and a wide field of view.

Pivot Windows
Pivot windows offer smooth, easy rotation to improve ventilation, light and day‑to‑day cleaning. Turning on a central pivot point, the sash rotates so both sides of the glass can be reached from indoors, making them highly practical for busy households.
They are ideal for upper floors, stairwells or places with limited external access. With balanced movement and a minimalist frame, pivot windows create a bright, modern finish that suits both traditional and contemporary homes

Sliding Sash Windows
Classic vertical sliders with the benefits of modern uPVC: reduced maintenance, improved insulation and period‑correct aesthetics for character properties.

Sash Horn Windows
Sash horn windows replicate the traditional charm of timber sash frames while offering the modern benefits of uPVC or aluminium. Decorative sash horns add character, making them perfect for period properties or homes wanting a heritage aesthetic without compromising on energy efficiency or security.

Bi‑Fold Windows
Bi‑fold windows are an excellent way to open up your home and create a seamless connection between indoor and outdoor spaces. Using multiple panels that fold neatly to one side, they offer wide, unobstructed openings that maximise airflow and natural light.
These windows are perfect for kitchens, garden rooms, and living spaces where you want to “bring the outside in” while maintaining excellent energy performance and security.

FENSA‑Registered Installation, GGF Standards & Certified Security
Every installation is completed by our own experienced glazing specialists — never subcontracted — ensuring consistent quality, safety and compliance across all projects. As a FENSA‑registered installer and proud GGF member, we work to recognised industry standards for workmanship, installation and customer protection.
Security is paramount, and all products we supply are certified and tested to recognised standards, including Secured by Design*, BBA Approved* and BS‑tested* performance. We believe our customers deserve quality and peace of mind as standard.
Our knowledgeable colleagues will guide you through the wide choice of traditional and contemporary frame styles, helping you choose the right options for your home, office or budget. Installing energy‑efficient windows and doors is an excellent way to reduce energy costs while enjoying brighter interior spaces and improved comfort. Our most popular glass specification — the Planitherm Glass Range — is designed to maximise warmth, clarity and natural light.
Our Bristol branch is also proud to hold BFRC rainbow rating certification, the UK’s most trusted and widely used energy‑performance ratings system for windows and doors.
*Please note that different glass types may affect the overall window rating.
