Double Glazing Supplier in Cardiff Heath Windows and Doors

Keep Up-To-Date with News from Heath Windows and Doors Cardiff.

We are passionate about home improvements and particularly about windows and doors.

We see windows and doors as more than something that opens and closes to let you or the light in and out. We see them as extensions of your personality and an expression of the way that you like to live. We love getting to know our customers and the reasons why they choose particular windows and doors. Do you choose a brightly coloured door or will you fall back to a safe neutral position when you come to the final choice? Will you change from the existing colour and arrangement or will you make a radical change.

These journeys fascinate us and we are here to help make that journey exciting for you. A major purchase for your home should be exciting and give you pleasure for many years to come. Our news pages help to give you some insight to our personality and help you think more about the choices you make.

As always, if you have any questions, please get in touch.

Condensation on windows

What Causes Window Condensation?

Do you ever look at your windows and wonder why they’re misty? Windows can look misty whether the water has formed inside, outside or even in between the panes of glass. If you're above a certain age you'll even remember when 'Jack Frost' used to visit and turn that condensation into magical frosty patterns.

Although it's not as cold in homes as it used to be, condensation is still not nice to live with. It spoils the look, creates damp pools on window sills and potentially causes mould if the window condensation doesn't dry quickly enough. It also affects the temperature of the room as the coldness emanates from the window. Whatever the reason for it, nobody wants it. To prevent it from happening, you first of all need to understand where it's coming from.

Employment Gets the Best Results

Companies that subcontract their work are extremely common, but it’s rare to find a team that fully employs their staff. In the window and door industry, great results come from employment. People who are employed are retained longer with the same company, are less rushed, and make fewer mistakes.

Retention Counts

Developing expertise takes time. Our staff can stay with us for extra training because we employ them. Subcontractors, on the other hand, don’t necessarily get the training they need to become an expert window and door installer.

Great windows and doors take some expertise to install. Not only does quality count on simpler windows and doors, but many people looking to replace their windows and doors are looking for an upgrade.

Not all showrooms are created equal. And not all showrooms have a curated selection after 30 years in business! Come visit us in South Wales to see all the beautiful quality products our family has to offer.

Traditional choices for doors meant they were made from only one material such as wood or metal. However, modern technology gives us the choice of a combination of materials for stronger and more secure doors. Composite doors are of superior quality and yet have complete aesthetic appeal to match your home decor and lifestyle.


The core of composite doors is made of wood and insulating materials protected by other layers with an outer layer made of weather resistant material. The different materials are glued together under high pressure. Composite doors are usually thicker compared to other types of doors.

Because they are made from a combination of materials, composite doors are extremely durable, strong and great looking.
