Where is Lockwood Windows based?

Lockwood Windows is based in Huddersfield, however can manufacture, supply and install products for domestic and trade customers throughout Yorkshire and the UK.

What is the difference between PVCu / UPVC windows and aluminium windows?

There are a number of differences between PVCu and aluminium windows including:

  • PVCu has a high thermal resistance protecting your home from external elements.
  • Aluminium has a poor thermal resistance which can mean that heating your home is more expensive.
  • Although aluminium is resilient it can bend and dent. Fully reinforced PVCu is tough and as a result should last longer.
  • PVCu is a great insulator for both energy and sound.

What security features do door and window products from Lockwood Windows have?

Our aim is to ensure that the products we manufacture and install are as secure as possible, so we offer customers the Kommerling 070 and C70 frame system for both windows and doors, as it is both energy efficient and secure with galvanised steel reinforcement.
