What makes our front/back doors special

We have been manufacturing double glazed doors for over 20 years, our secret of success is striving for the highest quality using the best materials.

Door designs

Because we manufacture your doors in our own factory we are not restricted to supplier design limitations, so we can tailor your doors to your needs, please use our unique on-line UPVC door designer.
Side panels/lights may be manufactured separately to the door including a free reinforced 15mm coupler for added strength.

Energy Efficiency (Approved Document L Compliant)

A new door from Modern UPVC Windows will make a real difference in the winter and help to reduce your home's energy bills, minimising heat loss. On glazed doors the special coating on each pane reflects the heat back into the room. We use the same argon filled sealed glass units as on our A+ rated windows.

Low Threshold Option Available (Approved Document M Compliant)

When combined with the low threshold option and a suitable width our doors meet current Approved Document M regulations for wheelchair access.

Standard High Security (see video)

Our doors have high security built in. As standard an exceptionally strong 5-point security lock with hookbolts that complies with PAS 23, PAS 24 standards and the police approved Secured by Design specification. Our doors are internally beaded, the glass or panels can only be removed from the inside.

Door profiles - Now with Optima

We use Profile 22, one of the leading extruders in the country. Our doors and windows match well.
We use the new 2016 Optima 70mm system with an attractive sculptured finish.


All of our door panels have MDF reinforcement to increase both energy efficiency and security.

Glass (Approved Document N Compliant)

We use the same sealed glass units that we use in our A+ rated windows comprising of:

  • Inner pane – Pilkington KS
  • Outer pane – Pilkington Optiwhite
  • Gas filling – Argon Gas
  • Spacer bar – SuperSpacer
  • Thickness – 28mm or 36mm for triple glazing
  • U-value – from 0.76 to 1.22  

Toughened glass is supplied in all areas except top lights to meet current building regulations (Approved Document N). All toughened glass is approved to Kitemark: BS 12150.
In addition, you may also add Georgian bar, Square lead or Diamond lead decoration to your glass.

New! Triple glazing

For even higher energy efficiency, we now manufacture the next generation of doors, triple glazed doors. Using the same advanced glass specification as our double glazed windows our triple glazed glass adds an additional pane of energy efficient Pilkington KS glass, increasing the thickness to 36mm.

Our handles, hinges, letterplates and other parts are of extremely high quality, sourced from reputable companies.
