The popularity of stylish doors has rocketed in the last few years. There is so much choice now but we make it easy for you with our online door designer that helps you quickly envisage different styles and colours. Your door must last a long time and can have a big impact on the kerb appeal of your home so it is a big decision - worth taking time over. Will you be conservative and choose something that blends in or be bold with a bright colour? We'd love to help you decide. We carry the widest range of doors from Solidor, Residor and Endurance.

Conservatory in Dinas PowysConservatories.

A conservatory provides light and energy into your home, revitalising your living space. The beauty of a uPVC conservatory will improve the space to suit your house and the needs of your family. No longer are you restricted to roof choices that mean your conservatory is limited to use when the weather is right. Our solid conservatory roof options mean that you can have the benefits of an extension without the cost. See more about conservatories here.

Replacement Conservatory Roofs.

If you have a conservatory that you are struggling to get the best use of, have you considered that you may be able to just change the roof. It's amazing how just replacing the roof can make you feel as if you have a brand new conservatory.

The most common change is from polycarbonate roof to glass double glazing which immediately upgrades to a more modern look but for a room that you can use all year round, you may want to think about a tiled conservatory roof. This is especially relevant now that so many people are working from home and wish to use the conservatory as an office. Normally a conservatory wouldn't be the most comfortable place to sit in the summer or the winter, being either too cold or too hot. The glare also makes it difficult to see the screen. A tiled conservatory roof will make it more comfortable for a variety of uses. 

Eurocell Equinox Vega Conservatory Roof.

Tiled conservatory roof equinox vegaIf you want more light than a full roof allows, you could choose the Equinox Vega which features large double glazed areas with roof lights of up to 1 metre wide of full-length glass to let in more light and still have that conservatory feel.

The inside features a ceiling that follows the lines of the roof so you have maximum space for that light airy feeling. You can even have lights fitted into the ceiling as you do in a normal room in the house.

You still benefit from that garden room feel because the sides remain conservatory windows rather than the normal construction of walls with a window that you would have if you had an extension. Find out more about tiled roofs.


Eurocell Garden RoomGarden Rooms.

If you've exhausted the space in your house and you're tripping over each other, maybe it's time to consider another room in the garden. Use it as an office, a place to escape, a music room or a playroom. 

Garden rooms are available in Steel or a timber-look composite. All are insulated and come with A-rated double glazed windows. 


How Much Do Windows and Doors Cost?

The cost of your double glazing and doors will depend on several factors. The quality of your new windows and doors certainly has an effect on the price, both in the materials used and the fixings. The difficulty for you as the customer is know ing the difference. Windows and doors look the same when they are fitted. It's only in time that you start to see windows dropping because the hinges aren't sturdy enough or frames bowing because the aluminium or steel inside the frame is not strong enough. The fitting can also make a difference. Your windows and doors need to move smoothly and this relies on level fitting. Unfortunately, the industry is known for sub-contractors who value speed over quality. That's the reason that as a premier window supplier we fully employ our installation engineers. They know that quality takes precedence and will take their time to ensure the perfect installation. 

Sometimes the perception of cost is related to house value. There is no difference in cost whether you live in Cardiff or anywhere else. A slimline aluminium window costs the same whether you have a 2-bed bungalow in the South Wales countryside as it does for a 6-bedroom house in the middle of Cardiff.

Double Glazing versus Triple Glazing.

The difference between double glazing and triple glazing is as it sounds. Double glazing has two panes of glass and triple glazing has three. In between the panes is a gas that helps insulate your home. Three panes of glass naturally give a bit more insulation but in our opinion, not enough to justify the huge extra cost and there are some negative aspects to triple glazing. Recent advances in double glazing mean that the difference in insulation may be measurable with technical equipment but is barely discernible for the homeowner.

The downside of triple glazing is that vision through the window is slightly distorted and it blocks more light. While it may offer a bit more insulation on colder days, this may be offset by the sun being less able to warm the room on sunny days.
