Sealed Units

 Upgrade Your Sealed Units – The Fastest, Cheapest Way to a Warmer, Quieter Home

Replacing old or failed double-glazed sealed units (the glass part) with modern, energy-efficient ones is one of the smartest home improvements you can make. No need to change the frames – in most cases we simply remove the old glass, fit brand-new A++ rated units, and your windows & doors perform like new (or better) in just a few hours.

Why Upgrade Your Sealed Units?

1. Dramatically Lower Energy Bills -Old 1990s–2000s units typically achieve around 2.8–3.2 W/m²K. Today’s best units deliver 0.9–1.2 W/m²K (up to 70 % better insulation). Many homes save £150–£350+ per year on heating once all windows are upgraded.
2. Stop Condensation & Draughts -Failed or single-coated units cause misty glass and cold spots. New units with warm-edge spacer bars and argon/krypton gas fill eliminate internal condensation and cold radiation
3. A Warmer, More Comfortable Home -Triple glazing or advanced solar-control double glazing keeps rooms warmer in winter and cooler in summer – no more sitting away from cold windows.
4. Big Noise Reduction -Upgrade to acoustic laminated glass and cut traffic, aircraft, or neighbour noise by up to 40 dB (feels like 75 % quieter).
5. Instant Kerb Appeal & Value -Misty, failed glass looks tired and dated. Crystal-clear new units make the whole house look freshly renovated and add genuine resale value.
6. Eco-Friendly & Future-Proof -Slash your carbon footprint and easily meet current or upcoming Building Regulation standards without replacing entire frames.
