How much heat is actually lost through windows and doors?
The amount of heat lost through windows and doors depends on the age, condition, construction and size of the property, as well as the glazing and frame specifications.
The Energy Saving Trust estimates that around 18% of heat loss in a typical home can occur through windows and doors.
That means the heat you are paying to produce can quite literally be escaping through the fabric of your home.
The older and less efficient your windows are, the more important it can be to consider where that heat is going.
Does improving energy efficiency mean I need an eco house?
Absolutely not.
You do not need solar panels, underfloor heating and a highly insulated new-build home to start improving your property’s energy efficiency.
Every home is different, and improving efficiency is often about taking sensible steps that suit the property and your budget.
Replacing draughty, single-glazed or very old windows and doors can be one part of a wider approach to improving the thermal performance of your home.
Think of it simply: the less heat you lose, the less energy you need to use to replace it.
Why does keeping heat inside matter when energy prices are rising?
With household budgets under continued pressure and the Ofgem energy price cap affecting the cost of household energy, reducing unnecessary energy use remains an important consideration for homeowners.
If heat is escaping through inefficient windows, doors and other parts of your home, your heating system has to work harder and for longer to maintain a comfortable temperature.
Improving the thermal performance of your home can help reduce unnecessary heat loss, allowing your heating system to maintain a comfortable temperature more efficiently.
It is not simply about generating more heat – it is about keeping the heat you have already paid for inside your home.
Can new windows make my home warmer?
Yes.
Modern energy-efficient windows are designed to reduce heat transfer and help limit draughts and cold spots around the window.
At Sapphire Windows & Doors, our uPVC windows are A+ energy rated as standard, exceeding the minimum Band C requirement for replacement glazing under current building regulations.
By combining modern frame technology with high-performance glazing and effective seals, today’s windows can provide significantly improved thermal performance compared with many older installations.
Can new windows help reduce my energy bills?
They can help reduce heat loss, which may mean your heating system does not need to work as hard to maintain your chosen indoor temperature.
However, the actual saving will depend on several factors, including the size and condition of your existing windows, the type of heating system you use, your home’s insulation, how you heat your property and your energy consumption.
Replacing windows should therefore be viewed as part of an overall energy-efficiency strategy rather than a guaranteed fixed saving on your bills.
Do I need to improve my home’s efficiency before installing a heat pump?
Improving the energy efficiency of your home can be an important consideration before installing a heat pump.
Heat pumps work differently from traditional gas or oil heating systems and are generally most effective when a property has good levels of insulation and a reduced heat demand.
That is why improving the building fabric – including insulation, draught reduction and, where appropriate, upgrading inefficient windows and doors – can be an important part of preparing a home for a heat pump.
You do not necessarily need to turn your home into an eco house. The aim is to make it as efficient as reasonably possible before asking your heating system to do more.
Can new windows keep my home cooler in summer?
Yes – energy efficiency works both ways.
Modern glazing is not just about keeping warmth inside during winter. The right glass specification can also help manage solar heat gain during the summer months.
This can help prevent rooms from becoming excessively warm when sunlight enters through large areas of glazing.
Depending on the orientation of your property and the amount of direct sunlight it receives, different glazing options can be considered to help balance winter warmth with summer comfort.
So, upgrading your windows is not simply about staying warmer in January. It can also help create a more comfortable home during the warmer months.
What makes a modern Sapphire uPVC window energy efficient?
Several components work together to improve thermal performance, including the window frame, glazing, seals and installation.
At Sapphire, our uPVC windows are A+ energy rated as standard, helping homes achieve a high level of thermal efficiency.
We also understand that energy efficiency is only one part of choosing new windows. Modern windows can provide improved security, reduced draughts, better comfort and a fresh appearance at the same time.
Our windows also feature high-security locking systems as standard, helping to provide both thermal performance and peace of mind.
