4. How to Compare Quotes

How can you compare quotes on double glazed windows & doors?

When comparing quotes, it is important to ensure you can check if the products on offer are of the same quality. Some companies will offer a product that is considerably cheaper than ours and seem too good to be true – it usually is!

When making such a large investment, such as replacing the windows and doors of your home, it is imperative to get the best product at a competitive price, as you want to be comfortable that your new products will last for many years to come. The cheapest option may be better on your finances short term, but if it is an inferior product it may actually cost you money in the long term. Quality and value for money needs to be judged over a longer period of time.

To try and help compare our Thermally Broken Aluminium products with other companies, we have put together comparison questions to help. It is important to remember that anyone can make claims about theirs or somebody else’s products, so always ask to see proof.

At Eco Smart Designs, we are confident that our product is the market leader in WA.

To ensure that you get the quality product you are expecting, ask these questions: 

  • Are the Aluminium profiles thermally broken?  If they are not thermally broken you may as well use single glazing! Aluminium is a very efficient conductor of heat and cold so the frames must be thermally broken to meet the thermal efficiency (u-Value) that double glazing is renowned for.
  • Are the windows and doors manufactured under an ISO 9001 Quality Management System?
  • Are the windows and doors manufactured using the latest precision automated machinery?
  • Are the windows and doors manufactured China under licence from the top European designers in the UK or Europe?
  • Do the windows and doors have co-extruded gaskets to ensure optimum weather performance and noise reduction?
  • Do the windows have a ‘U’ value of 1.2 to 1.7W/m2K as standard?
  • Is the glass used Low-E?
  • Are argon gas and warm edge spacer bars used as standard for maximum thermal efficiency?
  • Are the locking systems the most up to date?

Our Windows & Doors are better than the rest
