Our Stunningly Beautiful Double & Triple Glazing on Windows

There comes a time when you finally realize that your old worn out wooden or uPVC windows need replacing. The time has come to upgrade your home, and there’s no better time than now.

We now have so many different types of Aluminium and uPVC windows to choose from, plus a huge range of frame colours as well. These new windows will totally transform the look of your home, not to mention security and thermal efficiency.

We at Smart Homes NI go to every trade show, looking for the most innovative, aesthetic and best performing frames on the market today. We then join with those manufacturers to produce market leading frames here in our Northern Ireland factory.

This is precisely why we recently switched from making Rehau frames in favour of producing Deceuninck engineered frames. You can’t even compare the two because Deceuninck frames are far better than all the rest, due to the following:

  • Energy efficiency is A-Rated, with the potential for triple glazing
  • Rehau frames are only certified to PAS024 and BS7950, whereas Deceuninck have those certifications as well as BS7412, BS7413, and PAS023
  • Engineered with eco-friendly O70 Gold, making these uPVC frames highly recyclable
  • Frames are slimline sculptured for a higher-quality finish

     

    Furthermore, we specifically install each window with our proprietary SmartFit™ technique, so they are totally air-sealed. This protects against water seepage, draughts and other external impacts.

    We can also proudly announce that all of our windows, both uPVC and Aluminium, surpass the government’s standards for security, giving you complete confidence in you and your family’s safety.

    Now that prices are at the lowest they’ve been in years, there is no reason to put off upgrading your home to high performing beautiful new windows throughout.

    Wherever you live in Northern Ireland, we can take care of your needs through our office in Belfast or Lisburn.

    We look forward to hearing from you about any home improvement projects you may have and helping you to bring them to fruition. Please give us a call.

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.

Frequently Asked Questions

As the name suggests, double glazed windows are those made with two panels of glass formed into a single window. The two layers of glass are separated by a space that is filled with inert gas.

Triple glazing refers to the process of making windows by combining three panels of glasses into a single window unit. These are the ultimate thermally efficient windows that restrict heat loss to the maximum extent.

Yes, certainly they are! You can get double glazed windows & triple glazed windows available in different colours and designs in both aluminium and upvc frames.  Both are ideal for double and triple glazing in NI.

The double and triple glazed windows are given energy ratings based on factors like thermal transmittance, air leakage, solar factor, etc. The rating ranges from A++ to G where A++ is the most thermally efficient while G is the least. At SmartHomes NI, our windows achieve an A++ rating with a thermal efficiency of 0.8, a market leading product.

Along with high thermal efficiencies, these double and triple glazed windows are noise-resistant too. Since the double and triple glass panes are not in direct contact, the sound waves are softened thereby reducing the amount of noise passing through.

 We can also supply acoustic laminated glass which is used for homes in extreme noise areas, e.g. Near airports or train stations.

Our range of double and triple glazed windows exceeds the general security standards i.e. PAS24:2021 required for all residential properties in the UK. In addition to that, our triple and double glazing in Belfast comes with internal beading and a multi-point locking system that further increases the security aspects.

These double and triple glazed windows are extremely durable and can last up to 20 years if maintained properly. Most of our products come with a frame warranty of 20 years and 15 years of glass warranty. Once installed, you wouldn’t have to look for triple or double glazing windows near me for a long time.

Since all the windows are tailored-made depending on the size, style, and glazing preference, the installation time differs from one order to another. However, it usually takes 8 – 10 weeks which includes surveying, manufacturing, and installation of  you double or triple glazed windows.
