The Most Energy Efficient Composite Door

The Most Energy Efficient Composite Door from Lockwood Windows
The Most Energy Efficient Composite Door - from Lockwood Windows

The Solidor range of composite doors are the greenest, most energy efficient and most sustainable composite doors available.

Here's why:

  • all of the timber used in the doors are harvested from forests that are managed and sustainable
  • each door can be recycled at the end of its life
  • all doors are manufactured in the UK to reduce our carbon footprint
  • the thermally efficient reinforcing system is 100% recycled
  • the profile of each door has 5 chambers and is completely lead free
  • all doors have lead free skins and edgebanding.

All glass fitted in our doors is energy efficient Pilkington K Glass. This is a low emissivity coated glass which reflects heat back into the room whilst also letting in free heat from the sun, known as passive solar gain. Pilkington K Glass helps glazed doors to achieve high energy ratings to comply with Building Regulations Part L.

Steel Reinforcing

As standard, our composite doors also benefit from ultra-secure steel door frame reinforcing.

We use the Kommerling profile systems, which are highly energy efficient and extruded with a unique lead-free compound, and are reinforced with steel to ensure security.

They are 5 chambered for better thermal performance; have steel reinforced profiles; high security multi-point locking & shoot bolts; internal beading for enhanced security; a wide range of colours - 44 woodgrain and coloured finishes; and they are high impact, colourfast and lead-free PVCu profiles which are better for the environment.
