Over the last few months we have continued our Technical Twitter Takeover’s, featuring monthly hour long sessions dedicated to different topics affected by insulation and what we do here at Celotex. Within the Celotex Technical Centre (CTC) our fantastic team of technical advisors get asked a range of different questions so it is great to take some of those questions and explain them through a short afternoon of Twitter activity. It is also a great opportunity for those watching from across the social media stratosphere with a project enquiry to send in a Tweet using #AskCelotex to our technical team member to provide assistance.

Celotex and Sustainability

Did you know?

  • Energy used in homes is responsible for over 25% of the UK’s CO2 emissions
  • UK households account for 61% (and rising) of total UK gas consumption
  • UK householder spending on energy has doubled since 2003. A household is deemed fuel poor if it spends more than 10% of its income keeping warm
  • 45% of heat is lost through uninsulated solid walls. Installing solid wall insulation nationwide could save up to 14m tonnes of CO2. That’s the equivalent emissions of 3.5 million cars!
  • 2.3 million solid wall installations are required by 2022 to meet current climate change targets
  • High performance thermal insulation continues to be one of the most cost effective measures for improving thermal efficiency and tackling climate change

Celotex Supports Cold Homes Week

Cold Homes Week Celotex

Cold Homes Week, 2-6 February, gives focus to the important and neglected issue of fuel poverty which has a firm grasp of England. According to statistics from the Energy Bill Revolution (the hosts of this campaign) there are 7 million people suffering from fuel poverty in England, a figure that has seen increase over recent years.

This year proves to be a big year from the political perspective with a fast approaching election on the horizon that will shape the future of the United Kingdom. Currently, the Government defines fuel poverty as those spending 10% or more of their annual income on heating their home to an adequate level. The Cold Homes Week campaign aims to tackle this issue head on, raising awareness of fuel poverty and those affected as well as encouraging MPs to support the campaign.
