Top Tips for Draught Proofing Windows and Doors
Lifestyle
Draught proofing windows and doors is one of the simplest and most cost-effective ways to reduce heat loss, lower your energy bills, and make your home feel more comfortable. If you often notice cold spots, a chilly breeze near a window, or rooms that never quite warm up, unwanted draughts are likely the cause.
Small gaps around frames, hinges, and seals allow cold air in and warm air out, but with a few simple steps, you can quickly improve insulation and keep more heat where it belongs.
Why Draughts Appear Around Windows and Doors
Small openings around window and door frames allow cold air to enter and warm air to escape. These gaps often develop gradually as older timber frames shift or seals begin to fail. Aluminium frames are far more resilient, especially modern systems that include thermal breaks, but even they need regular checks to ensure they stay in top condition.
Draught proofing doors and windows is an important step if you want to improve insulation across your home. When you block these tiny openings, you reduce heat loss and rely less heavily on your heating system during the colder months.
Top Tips for Draught Proofing Windows & Doors
Inspect Your Existing Seals
Start by running your hand around the edges of each frame. If you feel cold air, your seals may be worn. Older rubber seals can deteriorate over time, which reduces their ability to keep out draughts. Replacing them is often inexpensive and can instantly improve insulation.
For window draught proofing that lasts, it’s worth choosing high quality replacement seals and ensuring they are fitted tightly without gaps.
Look for Gaps Around the Frame
Even a very small gap can let in a surprising amount of cold air. Check the edges where the frame meets the wall, as any slight movement over the years can widen these points. Silicone sealant is an easy fix for small openings, while expanding foam can support larger repairs before sealing.
This is one of the fastest draught proofing windows methods for older properties, where frames may shift more noticeably.
Consider Upgrading to Modern Glazing
Double glazed aluminium windows with thermal breaks provide far better insulation than older single glazed systems. Modern aluminium frames are designed to keep heat inside while also preventing condensation and cold spots.
Replacing tired frames with new draught proof windows can have a big impact on your comfort, particularly if your home is naturally exposed to wind or open landscapes.
Add Window Coverings for Extra Protection
Thick curtains or thermal blinds add an effective extra layer of insulation during colder spells. Although they’re not a replacement for properly draught-proofed windows or quality glazing, they can significantly reduce heat loss in the evenings. For a clean, contemporary aesthetic, integral blinds offer a sleek built-in solution.
This is a particularly useful option for rooms that aren’t used as often, or in areas where a full window upgrade is planned further down the line.
Benefits of Investing in Modern Aluminium Systems
Energy efficient aluminium windows and doors are designed to prevent heat loss across the frame. Thermal breaks inside the frame act as a barrier that keeps warm air inside and cold air outside. This results in a home that warms up faster and stays warm for longer.
At Express we see homeowners choosing aluminium systems not only for insulation but also for longevity. Modern frames resist expansion and contraction, meaning the seals stay in place and continue to deliver strong draught protection for many years.
“Our customers often notice the difference straight away once they replace older windows and doors. When gaps around frames disappear and modern thermal features do their job, rooms feel warmer and more comfortable. Draught proofing windows and doors is a key part of improving insulation, and aluminium systems offer dependable results year after year.”

How Draught Proofing Supports Better Energy Use
Heating accounts for a large portion of household energy usage. If your home is losing warmth through gaps around windows and doors, your heating system must work longer and harder to maintain a comfortable temperature.
Draught proofing windows and draught proofing doors helps you:
- Lower heat loss
- Keep rooms warmer for longer
- Reduce reliance on radiators
- Cut energy bills across the year
Even simple adjustments can help, but upgrading to thermally efficient aluminium glazing is one of the strongest ways to limit unwanted airflow.
When It Is Time for a Full Upgrade?
If you’ve sealed up draughts but still find certain rooms chilly or your energy bills creeping upward, your glazing may simply be past its best. Older timber frames can warp over time, and single or early double glazing struggles to keep heat in, no matter how many seals you add. You might also notice fogging between panes or rooms that never seem to warm up.
When these signs start to stack up, it’s usually time to consider a full upgrade. Modern aluminium frames paired with high-performance glazing offer a dramatic step up in insulation, helping your home stay warmer, quieter, and far more energy-efficient all year round.
FAQs
Is draught proofing windows expensive?
Most basic fixes like replacement rubber seals or silicone sealing are very affordable. More advanced upgrades like replacing older frames with new aluminium systems offer long lasting insulation and can reduce heating costs.
What is the best way to draught proof a front door?
A brush seal at the bottom, strong perimeter seals, and a modern letterplate are the key elements. If the front door is very old or warped, replacing it with a thermally efficient aluminium model gives the best long term result.
Does draught proofing affect ventilation?
No. Ventilation comes through controlled vents or planned airflow. Draught proofing stops uncontrolled cold air entering through small gaps that serve no purpose.
How long do modern aluminium windows last?
Aluminium frames are extremely robust. They resist warping, swelling, and movement, which helps maintain insulation and keep draughts out for decades.
A Warmer Home Starts With Draught Proofing
Draught proofing your windows and doors is one of the quickest and most effective ways to boost home warmth and reduce energy bills. By sealing gaps around frames, replacing worn or damaged seals, and upgrading to modern, high-performance glazing, you can retain more heat and enjoy a consistently comfortable living space all year round.
