The Benefits of Composite Windows and Doors

okohaus.co.uk Our AuraPlus composite windows and doors

When having a garden room constructed, the consideration of windows and doors may not have occurred to you. They are, however, definitely worth thinking about. The windows and doors you select will need to be secure and be energy-efficient.

The technology involved in glazing has come a long way in the last few decades. Continually evolving to improve energy efficiency and security. With double and triple glazing options available, there is also a selection of frame materials to choose from.

When installing windows and doors, you should be considering several things.

  • What is the average lifespan of the windows and doors?
  • How much will the windows and doors cost?
  • How energy efficient are they?
  • Are they secure?
  • Will they keep sound out?
  • Will they complement the design of the building?

For many year’s uPVC was the material of choice. Today, however, there’s a new, more sustainable kid on the block. Composite Windows, constructed of aluminium and timber provides greater energy efficiency, have a longer life span and are more sustainable than their uPVC counterparts.

We spoke to experts, Okohaus to find out more about sustainable composite windows and doors.

How Environmentally Friendly are Composite Windows and Doors?

We are all having to be more conscious about our individual carbon footprint; the products we buy should demonstrate responsibility. UPVC windows are derived from oil production; this means they are bad for the environment, requiring a significant emission of CO2 for their production. They are also difficult to recycle and once they reach the end of their lifespan, they are usually sent to landfill.

Composite windows are a far more sustainable product. This is because they use a combination of natural timber and long-lasting, robust aluminium external cladding. By utilising sustainable timber in the supply chain, manufacturers can achieve a much lower carbon footprint.  Okohaus ensure all of their products are FSC Chain of Custody certified. This means that the forests used for timber production are sustainably managed and for every tree cut down to produce a window or door, at least two more are planted.

These fresh, new trees grow quickly and therefore absorb more CO2 than older trees. CO2 is captured in the timber during the window’s lifespan, which is at least twice as long as the lifespan of a UPVC window, so they are actually carbon negative!

How Long Do Composite Windows and Doors Last

Composite windows and doors have a much longer life expectancy than uPVC frames. If maintained well uPVC windows and doors are usable for a maximum of 35 years, in most cases, they don’t reach this. Composite alternatives have a life expectancy of 56-83 years!

How Efficient are Composite Windows and Doors?

In terms of performance, composite windows also have the upper hand over both uPVC and aluminium alone. The U values (thermal performance) in Okohaus’ double glazed systems are comparable to triple glazing in aluminium or UPVC!

How Secure are Composite Windows and Doors?

When it comes to security, they tick all the boxes. Okohaus’ windows and doors are secured by design certified, meaning they are as standard, some of the most secure products on the market.  Usually, UPVC windows would have to have steel reinforcement added to achieve the same levels of security, which would also make them much poorer thermally.

Acoustically very high sound reduction levels are standard, even the busiest central London sites, for example, notice a difference.

When it comes to price, you may expect to pay more for this high-level product.  Composite windows and doors actually often work out cheaper than aluminium alternatives, especially when you compare like for like in terms of performance. They do come in a bit more expensive than uPVC. But the benefits far outweigh the price difference. Not to mention they last at least double the time of uPVC windows.

Windows and doors are as you see, an important consideration. It pays to do your research.
