Environmentally Friendly Composite Doors

If you’re in the market for a new composite door, you might wonder if your new home improvements are environmentally friendly.

We have all the information you need to make the most sustainable choices for your home.

What Does Environmentally Friendly Mean?

Environmentally-friendly can mean a lot of things, but when we use it in terms of things around the home, it refers to the creation of items using materials and processes that don’t use the earth’s natural resources in a wasteful way. 

Some popular sustainable items around the home include solar panels, gas stoves, and furniture made in a sustainably responsible way. 

What Is a U-Value?

Thermal transmittance (u-value) is a measure that represents how effective a particular material is at insulating the space it’s in. It looks at the rate of heat transmitted through a structure. 

It uses the unit W/m²K; the lower the U-value, the better a structure or material is at insulating heat. 

What Makes Composite Doors Sustainable?

The number one reason composite doors are considered sustainable is that the doors are fantastic at insulating your space. 

Keeping the home warm can cost a lot of money, but it also costs the environment a lot when you have to power heaters, radiators, and towel rails. 

The UK government has caught onto this, making new regulations that require all composite doors to have a U-value of 1.4 W/m2k or below. 

Previous external doors were traditionally made with door materials like timber. As a material, it’s not very sustainable as it doesn’t insulate very well and struggles to be recycled.

Modern composite doors include more insulating thermal glass; some are even triple-glazed. 

Simply buying a solid composite door can lower your carbon footprint because they last a lot longer, with some lasting 30 years. 

For multiple weather conditions, getting new composite doors from Value Doors is a great idea.

Our doors use a PVC weather bar that prevents water from leaking through and the wind from swooping in and lowering your house temperature like traditional aluminium doors would.

Why You Should Switch to a Grey Composite Door

There are quite a few reasons our doors stand out from competitors. 

Made in England

All doors are made in England, meaning there is no shipping from other countries; it is all within the UK, lowering carbon emissions. 


Value Doors products are accredited by the correct regulations and bodies, ensuring that the products you receive are of the best possible quality. 

We believe in the products we offer, each with a ten-year guarantee. 

Energy Efficient

The energy efficiency of Composite Doors is one of the features that makes them such a great investment for a home.

Our doors are super energy-efficient; they all use low-density timber made with Glass Reinforced Polyester, which is stronger and more durable than regular PVCu.

These elements act as super insulators, meaning you rely less on energy-consuming devices to stay warm than you would.

All the PVCu materials use sustainable calcium zinc in their manufacturing process. Plus, the entire supply chain works with energy efficiency as one of its top priorities.

All the products use 100% recyclable materials and a super high energy rating, meaning no lead-based additives.

Strong and Secure

Our composite doors are solid and have a range of security features provided by the famous Yale. 

The strength of the doors means they require a lot more wear and tear before needing to be replaced, reducing how many doors end up in landfills or recycling plants.  

Timber-Looking Weather Bar Keeps Heat In

Your new door arrives with a weather bar that aids in keeping bad weather out and your heat in (although they are not fireproof as standard). Water damage can lower the longevity of your door very quickly.

Are composite doors sustainable?

Absolutely, a composite door needs a low U-value to ensure it can insulate the space it’s in to reduce the need for heat. 

How do I know my composite door is low emission?

The best thing to look out for is accreditation.

What can I do to make my home eco-friendly?

The more environmentally conscious features, the better. Value Doors offers a full range of fittings and ecologically friendly doors. 

Wrap Up

Stunning composite doors are a great way to improve your environmental impact by making small changes in your home design. The doors are insulating while also being made from sustainable materials.
