Energy Efficiency: Stopping the Drafts
The Cost of Cold Air
Drafts are like having a window left slightly open all year round. In the UK, where heating accounts for the majority of household energy spend, stopping these unwanted air leaks is the most cost-effective way to improve comfort.
Our **draft-proofing calculator** provides an estimate of the financial and environmental benefits of sealing your home against the wind.
Quick Fix Impact
Important: Maintain Ventilation
While stopping drafts is good, your house still needs to 'breathe'. You should never draft-proof rooms where there is an open fire or a gas appliance with a permanent air vent.
Additionally, kitchens and bathrooms need ventilation to remove moisture. If you seal these rooms too tightly, you will likely experience condensation and mould growth on cold surfaces.
Payback Period
Draft-proofing materials like foam tape and brush strips are very inexpensive. In most cases, the energy savings in the first winter alone will pay for the cost of the materials, making the 'payback' almost instant.
CO2 Reduction
By reducing the amount of gas or electricity needed to heat your home, you are directly reducing your household carbon footprint. It is one of the greenest DIY tasks you can perform.
Pro Tip: The Candle Test
On a windy day, hold a lit candle (carefully!) near the edges of your windows and doors. If the flame flickers or bends, you've found a draft that needs sealing.
