Improving the energy efficiency of sash windows to reduce heat loss.

Draught proof your property

Older buildings don’t need to be draughty. Draught proofing your property is a fairly low-cost way to reduce heat loss and lower your energy bills. You can draught proof windows, doors and loft hatches.  Draught proofing is a good solution as it won’t affect the look of a traditional building.

Windows.
General wear and tear may lead to too much air leakage. Draught proofing sash and case windows will reduce air leakage by up to 80%. This has a big impact on reducing heat loss.

Doors.
To reduce heat loss from an external door, you can: draught-proof around the door edge draught-proof around the letterbox

Loft hatches. 
Insulate and draught proof loft hatches to stop warm, moist air from getting into the roof space.

Draught proofing benefits:

  • reduces heat loss
  • improves noise insulation
  • helps to stop dust getting in
  • is cheap and highly cost-effective
  • doesn’t affect the look of sash windows

First things first – double glazing keeps your home warm 

Double glazed windows are the number one most efficient and cost-effective way for you to insulate your home, and keep it warmer for longer. In fact, a house can lose its heat around twice as fast with regular single-glazed windows and doors.

So, how does double glazing work, exactly? 

Since double glazing uses two glass panels, it retains indoor heat by trapping the air in the gap between the two panes. The gap is filled with gas, which is a poor heat conductor. As the heat can then no longer escape your home through your windows, you rooms will naturally stay warmer for longer. This is undoubtedly the most common reason why people install double glazed windows into their homes, and why many more are likely to consider getting them fitted during the winter season.

Double glazed windows help you save energy and save money 

If you’re trying to improve the energy efficiency rating of your home, one of the best (and most cost-effective) things you can do is invest in double glazing all your windows and doors.

This is a direct result and outcome of the previous point. As double glazing effectively maintains the warmth of your home, you won’t need to turn on your heating as high as you probably used to. And you definitely won’t need to switch it on as frequently, as the double glazing will retain the heat for much longer.

Now, we’re all aware of how costly it can be to heat a whole house through winter. Sure, you’ll be investing more in the double-glazing installation costs upfront. But, you’ll actually save a huge amount on your energy bills in the long-term.

You simply won’t need to use as much energy as you would in a property with single-glazed windows and doors. The science of the two glass panes will result in a much more comfortable temperature throughout your home, and you’ll see the positive financial impact of this once you see your heating bills.

Not only that, think of the impact of all that reduced energy consumption on the environment! It’s definitely one of the easiest eco-friendly home improvements you can make.

Installing secondary glazing can reduce heat loss by 63%, making it one of the most effective ways to improve thermal performance. Heat loss can be reduced by more than 75% when secondary glazing is used with other methods like blinds and shutters. You can remove secondary glazing in the warmer months when it’s not needed.

Fitting secondary glazing involves attaching a second sheet of glass or acrylic to the inside of the window frame.
Minimal changes are needed to the window fabric, and the glass panel can be easily removed. The character of the building from the outside is largely unaffected.

Secondary glazing:

  • reduces heat loss  by 63%
  • can filter out some outside noise
  • helps to stop dust getting in
  • is a cost-effective solution
  • generally cheaper than double glazing
  • doesn’t affect the look of sash windows

Use shutters if you have them – this is one of the best ways to reduce heat loss at night. Single glazing lets in more heat from the sun and shutters help to trap warmth inside overnight.

Timber shutters reduce heat loss by 51%.  Consider having ill-fitting shutters restored. If the original shutters have been removed, it’s possible to have new shutters made.
