How Energy-Efficient Windows Can Cut Your Heating Bills This Year

If you’ve noticed cold draughts around your window frames or watched your energy bills creep higher every winter, your windows could be the culprit. Up to 20% of a home’s heating is lost through old, inefficient, or single-glazed windows, forcing your central heating to work overtime just to keep your living spaces warm.

At Sealglaze, a family-run business with over 50 years of experience based in Hitchin, Hertfordshire, we help homeowners restore comfort, boost thermal efficiency, and lower energy costs with modern Planitherm™ double-glazed units.

Here is everything you need to know about upgrading to energy-efficient glazing—and why replacing your glass doesn't have to break the bank.

What Makes Planitherm™ Glass So Special?

Not all double glazing is created equal. Standard glass allows internal heat to pass directly out into the cold air. Planitherm™ energy-efficient glass, on the other hand, utilises advanced low-emissivity (Low-E) coatings designed specifically for the UK climate:

Heat Reflection: The micro-thin coating on the inside pane reflects room heat back into your home rather than letting it escape.
Solar Heat Gain: It allows natural warmth from the sun to filter through, helping heat your home naturally during sunny winter days.
Eliminated Cold Spots: Advanced perimeter spacers and insulating gas between the panes eradicate cold zones near windows.
Did You Know? Upgrading from standard double glazing or single glazing to Planitherm™ glass units can significantly boost your property's Energy Performance Certificate (EPC) rating.

Key Benefits of Upgrading Your Windows

Lower Monthly Heating Bills: Retaining more heat inside your rooms means relying less on your heating system, yielding direct savings on your monthly energy bills.
Reduced Condensation: High-performance glass keeps the interior pane warmer, preventing moisture from pooling on the glass and causing dampness or timber decay.
Noise Reduction: Multi-pane sealed units dampen external traffic and neighbourhood noise for a peaceful indoor atmosphere.
Environmentally Friendly: Consuming less energy reduces your household’s carbon footprint, making your property greener.

Spread the Cost: Replace Glass Unit by Unit

Replacing every window frame in a house can feel like a daunting expense. Fortunately, if your existing timber or uPVC window frames are structurally sound, you don’t need to replace the entire window assembly.

At Sealglaze, we offer a cost-effective alternative:

Glazing Unit Upgrades: We can replace just the old or misted glass panes with new, high-efficiency Planitherm™ units.
Flexible Phasing: You can spread the financial investment by upgrading one or two rooms at a time, fitting your budget comfortably.
