Our Sustainability Commitment

Here at Advanced, we are fully committed to becoming as ENVIRONMENTALLY friendly as possible in all aspects of our business.

Not only do our products help homeowners achieve excellent energy efficiency in their home and reduce carbon emissions as a result, but we also work to reduce waste and emissions in our own manufacturing process.

80% of our window frames are made from recycled materials, and by sending waste materials to a recycling centre, rather than landfill, we have reduced waste by around 150 tonnes.

Energy Efficiency

All windows and doors supplied and installed by Advanced are ‘A’ rated for energy efficiency and could help you reduce frame emissions in your home by up to 70%.

If you are looking for replacement windows, energy efficiency should be right at the top of your checklist.

Doors and windows are major contributors to domestic heat loss in Cumbernauld and across Scotland, and poorly installed or older units could be costing you thousands every year in unnecessary home heating bills.

Our windows and doors have carefully been designed to minimise heat loss and achieve some of the best U-Values anywhere in the industry (The scale used to measure thermal efficiency of windows).

Our standard double glazing alone achieves a u-value of 1.4 W/m2K, an impressive figure that can be lowered further to 1.2 W/m2K.

Installing triple glazing can see you lower this even further to just 0.8 W/m2K.

A huge amount of effort has gone into achieving these numbers and some of the key design features allowing us to do so include:
  • Thermo spacer bars eliminate cold spots and condensation
  • Soft Coat Xtra coating
  • Energy reflecting glass
  • Argon gas filling

When choosing new windows and doors one of the most important things to look for is security features.

Your windows and doors are responsible for protecting you from unwanted individuals attempting to force their way inside, and it is incredibly important that they are as robust as possible.

To help you keep your home and family safe, we have designed our doors with security in mind, with multi-point locking systems as standard, fully welded frames, and strong hinges.

All glazing bead is also placed on the inside pane of glass so that it cannot easily be removed from the outside of the property.

Laminated and reinforced glass options are available if you have additional security needs.

For ultimate protection, why not consider choosing from our range of composite doors that combine all the function and style of uPVC with the strength of a solid wooden core.

Asked Questions

1. What sets apart "sash" windows from "casement" windows?

Sash windows are characterized by their traditional design, featuring a vertical sliding motion. On the other hand, casement windows offer greater flexibility with openers that can be pushed out or tilted in.

2. Do timber effect sash windows closely resemble real timber?

Our uPVC timber effect windows boast high-quality custom-made decorative finishes, providing a remarkably realistic appearance. We meticulously match these windows to existing frames, ensuring they are virtually indistinguishable from real timber, even at a distance.

3. What is the typical installation time for windows and doors?

The installation duration varies depending on site conditions and complexity. Generally, a two-person installation team can complete three to six windows per day.

4. Who installs your windows?

We exclusively deploy our fully trained and accredited in-house installers for all our projects.

5. Will removing window and door frames impact wiring or electrics in my home?

Typically, this is not an issue. However, if wiring is encountered during installation, work may be paused until a qualified electrician ensures a safe working environment.

6. Can burglars easily gain entry by removing the glass from your windows?

No, our Premier range features internally glazed windows, preventing the removal of glass from the outside unless it is broken. Glass removal can only occur from the inside.

7. Do your windows offer child safety features?

Certainly, we offer various safety and security solutions tailored to your needs. Our team will recommend the most suitable options at competitive prices.

8. Is cleaning obscure or decorative glass challenging?

No, as the pattern is on the inside of the pane, the outer surface of obscure or decorative glass is smooth, facilitating easy cleaning.

9. Do you have sash windows that tilt inwards for cleaning?

Yes, we offer such windows; however, sash horns cannot be included as they interfere with the tilting frame.
