How much can I save on energy bills with double-glazed windows?

Let’s use a three-bedroomed semi-detached home in Redhill as an example and the replacement of all existing single-glazed windows with double-glazed units. In this instance, new UPVC or aluminium windows save you between £90 and £120 a year on your heating bill. Because double-glazed windows last for around 20 years, that’s £2,100 over the lifetime of our products.

As you can see, an installation from Future Windows goes a long way towards paying for itself over the years.

It’s also important to ensure any glass in front and back doors is double-glazed to further improve energy efficiency. We provide double-glazed aluminium doors, composite front doors, patio doors, French doors and bi-fold doors.

What are the benefits of double glazing?

Apart from the undoubted quality of our products, the main benefits of double glazing are stylish design work and a significant increase in the value of your home. You’ll also notice better energy efficiency and reduced heating bills, alongside better heat and noise retention, particularly in conservatories where users really value warmth and quiet.

Yale locks and hinges increase security and vented design work reduces condensation on the inner panes.

What is UPVC?

UPVC is an acronym of Unplasticised Polyvinyl Chloride. The “unplasticised” part indicates that UPVC doesn’t have the same flexibility as normal plastic. Rigidity makes UPVC window frames ideal for double glazing. UPVC is the most cost-effective option for Redhill residents. Traditional timber frames are three times more expensive and much less efficient.

UPVC windows are extremely durable and require no maintenance other than an occasional wipe with a cloth and warm water.

Future Windows offers quality UPVC doors as well as windows. This includes patio doors, bi-fold doors and French doors. We also specialise in composite front doors.

What are the advantages of aluminium windows and doors?

Aluminium doors and windows are the greenest option because they are so easily recycled and, when processed, they only use 5% of the energy required to produce new aluminium frames from scratch. Aluminium windows and doors are stronger and have slimmer profiles, so they can include a larger area of glazing that’s ideal for letting more light into homes and conservatories.

UPVC is recyclable but only up to around 10 or 12 times.

What sits between the panes of double glazing?

There are two layers of glass in double glazing (and three in triple glazing) with a gap of approximately 20mm between them. Energy-efficient aluminium and UPVC windows use gases like argon, xenon and krypton, the last of which has nothing to do with Superman! These gases sit between the individual panes of glass and keep homes warmer during winter.

The same gases in double-glazed windows also keep homes and conservatories cooler during the spring and summer months.

Will I need ventilated windows?

Double-glazed UPVC windows and aluminium windows have a more airtight design than single-glazed frames. This can lead to a build-up of condensation in some Redhill homes if you do not have enough ventilation. Some replacement windows have trickle vents incorporated into the frame and these provide controlled levels of ventilation. Condensation can sometimes occur with Low-E double glazing.

Gases keep heat inside a property, so the outsides of windows remain cool. This lets condensation build up during cold weather, but this isn’t a problem and rarely causes damage.

Do you supply and install doors?

As well as being a leading name in windows, our company is a trusted choice for all kinds of entrance doors. We provide UPVC and aluminium doors as well as composite front doors. Design options include bi-fold doors, French doors and patio doors, to name a few.
