TRUSTED PARTNERS & ACCREDITATIONS
PERFORMANCE
Built for British weather, designed for everyday life
Every window we install meets and exceeds current building standards — and most go well beyond what's required.
Energy Efficient Windows
Market-leading components — quality glass, warm-edge spacer technology and multi-chamber construction — work together to keep heat in and bills down.
Acoustic Performance
Double glazing is well-known for cutting noise. Our profiles can bring outside noise levels down by as much as half — a real difference if you're near a busy road.
Quality & Performance
Our chosen profile meets and exceeds all current building standards, with high-performance window systems, robust hardware and the latest glass technology.
Weather Performance
All our windows achieve the highest BSI ratings for wind, water and air — proper protection from whatever the British weather throws at your home.
Enhanced Security
Up to 6-point locking with two locking points per shootbolt and double cam locking centrally. A patented docking system stops sideways movement under attack.
Low Maintenance
Strong, durable & resistant. uPVC windows do not rot, fade or rust. Our chosen profile is resistant to salt spray and cycle tested over 50,000 times for ultimate long-term performance
Every window comes Smart as Standard
Right now, every window we install includes the full Kubu smart kit — sensors, hub and app. Check your windows from anywhere, get alerts if one's left open, and rest easy when you're out.
Built into every Avantis Intellect lock we install
Sensors and hub posted direct from Kubu — no waiting
Free app for iOS & Android — no subscription
Use it or don't — your windows work the same either way

FRAME PROFILES
Three profiles, each with their own character
The profile is the shape of the frame edge. It's a small detail visually, but it defines whether your windows look traditional, contemporary or period-authentic.

From classic white woodgrain to contemporary anthracite grey — pick a finish that suits the character of your home.
