When it comes to keeping the cold out and the warmth in, nothing works quite as effectively as replacing old, inefficient windows with high-quality, energy-efficient ones.
However, even the most modern windows can benefit from a few extra layers of insulation. With a handful of smart, affordable tweaks, you can keep more heat inside, reduce energy waste, and make your home feel snug all season long.
The Permaframe team have prepared this short guide to get your windows winter-ready and your home feeling warm and welcoming.
When to Replace Your Windows
If you’re dealing with misted-up panes, chilly draughts, or rooms that never seem to warm up despite having the heating on full blast, your windows may be the cause.
Cracked glass, warped frames, or windows that stick when you try to open them are all warning signs.
Replacing your windows with energy-efficient double glazing will dramatically improve comfort and help lower your energy use throughout the colder months.
Replacement or Insulation – Which Makes More Sense?
Insulating your existing windows can be a cost-effective short-term solution, but older or single-glazed windows often lose too much heat for insulation alone to make a big difference.
Modern energy-efficient windows not only block draughts but also reduce your heating bills year after year, meaning your investment soon starts to pay for itself.
Different Ways to Insulate Your Windows
Even with high-performance windows, a few simple upgrades can go a long way towards keeping warmth in and cold air out:
Window Film – Adds an invisible insulating barrier to the glass, reducing heat loss by up to 30%. Easy to install and remove.
Thermal Curtains & Blinds – Thick, lined fabrics hold warmth inside while giving your room a cosy, stylish touch.
Caulking & Weatherstripping – Fill in small gaps and cracks around frames to stop draughts. Caulking lasts longer, while weatherstripping is easy to remove.
Bubble Wrap Insulation – A budget-friendly fix that traps air and slows down heat loss. Ideal as a temporary winter solution.
Secondary Glazing – Adds a discreet extra pane inside your existing frame, great for improving insulation in older or listed properties.
Draught Excluders & Insulation Tape – Simple, low-cost solutions for sealing gaps around window sills, frames, or even doors.
Even if your windows are already energy-efficient, these little extras can make your home feel warmer and more energy-conscious this winter.
Whether you choose to upgrade your windows or simply add extra insulation, the result is the same: a cosier, more efficient home you’ll love spending time in.
