What is draught proofing?

Draught proofing is the process of sealing your home against air leakage. Air leakage causes draughts, resulting in cold surfaces and uncomfortable rooms. Excess heat is quickly lost through gaps in sashes, seats and other areas, which can lead to condensation and mould within your home. If your home has been draught-proofed you can be confident that the hot air from your living space won’t be lost to the outside world. Draught Proofing: At its simplest level involves sealing gaps and cracks around doors and windows with a foam or silicone based sealant.

At Trade Timber Windows and Doors Brighton, we install draught proofing strips on all popular window profiles and types including traditional sash windows.

What are the Causes of Sash Window Draughts?


Old Window Seals

Biting cold draughts coming in through old window seals are a telltale sign of sash window draughts. Whether it’s a loose screw or a piece of rotten wood, if the seal around your sash windows is damaged then you can be sure that warmth will be escaping in winter and cool air will be seeping in during summer.

Damaged window seals

The window seals are designed to separate the inside of your home from the cold, wet weather outside. If they are not fitted correctly and have been damaged in any way, air will pass through them as you draw the sash up or down. You may have noticed draughts entering around the base of your sash windows as you open and close them. This is caused by damage to the window seals.

Old Window Frames

Old window frames can be the source of draughts. With parts moving or failing over time warping, cracking, or splitting may all prove to be the cause of draughts in older buildings.

While modern window frames are made from sturdy materials and with care taken on production lines to ensure compatibility, there’s no denying that nails can loosen. When this happens it allows air to leak in along the sides and underneath the frame.

Damaged Window Frames

Don’t let a draughty sash window ruin your home. A draught may seem like such a small issue but it can have a huge impact on the temperature of your home. If left untreated over time, it can cause damage to your frame and lead to more expensive problems.

Poor installation

Draughts around sash windows are often caused by poor installation. The problem may be with the incorrect or poor fitting of the bottom rail, which can stop the sashes from closing properly. Another cause can be if the central mullion (vertical piece) is not fitted tightly against the top and bottom sash frame.

Damaged structure

Damaged sash windows, such as warped or damaged wood frames or cracked glass can leak and disrupt the seal between the two sections of the window. This is one of the most common causes of draughts from your sash windows.

Absence of draught-proofing seals

Draught proofing seals help improve energy efficiency by stopping cold air from entering the property through unsecured or worn windows. If you haven’t checked your windows recently, it’s probably worth giving them a quick check over because a draught can account for up to 10% of your annual fuel bill.

If you are experiencing any of the above, it’s best to contact us on 01273 257 597. We’ll check whether any missing or damaged pieces are to blame and suggest how they may be fixed.

What are the Benefits of Draught Proofing Your Sash Windows?

Reduced energy bills

Draught proofing your sash windows can reduce heat loss by up to 50% and draughts by up to 95%. That could save you money on energy bills all year-round. You’ll be surprised at how adding draught-proofing will give your property a much warmer, cosier, and more comfortable feel to it.

Eliminates draught, rattling, and wobbling

Draught-proofing your sash windows will undoubtedly eliminate draught, rattling, and wobbling in sashes. It’s the most economical method of providing you with a home that is comfortable all year round. Draught Proofing will effectively remove draughts and stopping noise transmission, by adding 50mm to around 75mm of insulation to your Sash Windows.


Draught proofing also improves the soundproofing from outside noises. Sash windows that are not draught-proofed can let in a lot of noise from outside, you’ll be able to hear everything that is happening on the street. Draft proofing helps to block outside sounds which will help your children get a better night’s sleep!

Healthier home

Having draught-proofed windows installed will help you create a healthier home since it stops air leaks that can allow in harmful dust and allergens. It will also reduce the risk of condensation and mould, which can damage your home’s structure and make it dangerous to live in.

Frequently Asked Questions

Does draught-proofing sash windows work?

Not only do draught-proofing sash windows work, but they are easy to apply, change the appearance of your home, and make a huge difference to the comfort inside your property. It’s no wonder that draught-proofing has become one of the UK’s leading energy saving solutions for homeowners who are looking to reduce their energy bills.

How long will draught-proofing measures last?

The right draught-proofing measures will save you an amount of money each year equivalent to the cost of installing them. The longer you have them, the more money you’ll save. But the benefits don’t stop there – your home will be more comfortable and have lower bills for many years to come. If they are installed by a competent person, you can expect them to last for as long as possible, even decades.

How do I stop my sash windows from rattling?

To stop rattling sash windows, the first step is to identify which window panes and sashes are in contact. Check the window from the inside by closing it gently with one hand and feeling for which panes are touching or about to touch. Once you know where they are touching, you’ll be able to make some adjustments. It’s important to do this delicately so as not to weaken the window.

Does draught-proofing require building regulations?

No. Draught proofing does not require the time and expense of the building regulation process. The process is a simple cost-effective solution to reduce losses from draughts and heat leaks in existing buildings.

How long does the draught-proofing process take?

Draught-Proofing won’t take long, but it could take two hours or more to properly seal your home. Once we have finished this process you will be confident that the weather won’t disrupt your life, it won’t break a sweat and it will still be there for you for a very long time.
