Double Glazing in Cardiff
As Cardiff residents know, the climate in South Wales can be a mix of sunshine, rain & chilly winds. In such an environment, having energy efficient windows & doors is important.
Other things to consider:
Frame Materials – chose frames that are durable, weather resistant & low maintenance. Popular choices include uPVC & Aluminium
Security – for any homeowner security is a top priority. Our uPVC windows can be supplied to Secure by Design standards & are smart sensor enabled.
Style & Aesthetics – Cardiff’s architectural diversity allows for various window styles. Consider the aesthetics of your home & chose double glazing that complements it’s design.
Noise Reduction – Given Cardiff’s urban environment, for homes closer to the city centre & on main roads, noise reduction maybe a concern. Double glazing with acoustic glass such as Planitherm Comfort or Comfort Plus can help to minimise external noise, providing a more peaceful living environment.
Local Regulations – Compliance with local standards is essential. Cardiff has 27 conservation areas that have been designated for their special architectural or historic interest, so it is always worth checking if there are any specific regulations or guidelines that apply to your Cardiff home.
How much will it cost is a question that we get asked regularly. As your new windows & doors are made bespoke to fit your home perfectly in order to give you a quote, one of our design team will need to chat to you about what you have in mind and get some measurements of the existing windows. Book a consultation through our online diary system or give us a call.
