SmartFit™ Installation process

To get the true quality and performance out of your new windows it’s vital they’re installed accurately.

The quality of installation is often over looked by homeowners.  They see that 2 companies sell the same product therefore the outcome of the installation will be the same.  Sadly this is rarely the case.

We’ve created an industry leading installation standard for ourselves called our “SmartFit™ method, which ensures maximum energy efficiency and product longevity.

Below you can read a featured article written about us and our “SmartFit™ method in the popular home improvements website Cosmopolithome.

Frequently Asked Questions

We use Deceuninck and Veka Flush Casement Window systems, which we consider to be the best on the market. 

We made the switch to Deceuninck and Veka after we attended the UK’s biggest product expo and were blown away by the quality of their frames. We haven’t looked back since.

There are lots of great reasons to use Flush casements when upgrading or changing your windows;

  • They are cost efficient over their aluminium counterparts, but with that same seemless finish.
  • They are incredibly energy efficient and can easily attain Window Energy Ratings of A+ and above, which is one of the highest amongst any window material.
  • They are very easy to maintain and have a typical lifetime of around 20 years, as long as they are maintained.
  • Flush upvc windows can be finished in a variety of colours and wood grain textures, giving you the opportunity to create bespoke windows that are unique to you.

We offer both double glazing and triple glazing in our flush casement windows.

Double glazing is provided as standard and makes up 80% of the glazing in the UK. They are made up of two panes of glass which are separated by a small cavity; this cavity is filled with an inert gas such as krypton or argon. This combination allows for excellent thermal efficacy as it reduces the amount of heat that can escape through the window drastically and also reduces noise going out of or coming into your home.

Triple Glazing as opposed to using two pieces of glass like double glazing, uses three. This creates an extra cavity which is usually filled with an inert gas, just like in double glazing. This helps even more with thermal efficiency and noise reduction.

You can have different styles of glass to make your flush windows more unique and better suited for you and your home. We offer clear glass along with decorative glass, obscure glass, low-e glass and toughened glass options;

Decorative glass is glass with a particular pattern or design e.g. Georgian bars where as obscure glass would be something like a frosted or satin pattern which is excellent for privacy. We also offer low-e glass which offers better thermal efficacy and toughened glass which can be up to 5 times stronger than regular.

Our flush upvc windows easily meet and surpass the PAS24:2021 certification which is the required security standard for all residential properties in the UK. However we also offer additional measures that increase our windows security.

These include;               

Multi-point locking mechanism; which offer locking points around the frame making it much more difficult to force entry.

Internal beading; this means that the glass for the window is inserted on the inside of the window frame (inside your home) rather than the outside, meaning it can only be removed from the inside. Traditionally windows were beaded externally however with improved security features on the frames it makes more sense for the windows to be internally beaded.

Key operated handles; which allow you to lock the window which further increases the difficulty when trying to force entry externally.

Secured by design; this is an official UK Police scheme and certification, which recognises high levels of security amongst a variety of home-improvement products, including our windows.

As all of our Flush upvc windows will be bespoke to your home they need to be manufactured from scratch. This means that lead time can vary depending on how many windows you require along with how many orders our factory is currently processing. However, typical lead time from survey to fitting is 6 weeks.
