Got a FENSA certificate?

9 Dec

Since April 2002, homeowners need proof that their replacement windows meet current building regulations. Do you have proof that they do? If you used a FENSA installer then you will have received a FENSA certificate, that can be used as proof of compliance when needed. In our latest poll, we ask if you have had replacement windows installed, do you have a FENSA certificate?

Please take a few seconds and let us know…

Heating on! Winter is here…

8 Dec

It’s strange how we all have “markers” in our year – in this case, we feel that Fireworks night marks the arrival of Winter. Yes, the time of “Gunpowder, Treason and Plot” is behind us, and the next marker in 2011 is that of Christmas. So winter is upon us, and the heating is back on.


Heating side effect

In the summer months we don’t use our heating, but once winter is here, we find the heating is on in the morning and the evening, perhaps even during the daytime? One of the side effects of having your heating on is condensation on your windows.

The problem is the way in which we heat our homes, no longer do we have open fire places and lofty ceilings, rather we have radiators dotted around the house, we have loft insulation and lower ceilings, and we even have nice fitted carpets. All of which mean water vapour cannot escape, so instead it forms on colder surfaces, and that’s on our windows in the form of condensation.


Condensation on some windows but not others

You may find some of your rooms have no condensation in them, while others have water streaming down the inside of your windows. This is due to air circulation and ventilation of rooms. You will find that your “dry” rooms don’t have so much water vapour being generated in them, or they have greater ventilation.


Condensation on the outside of your windows

While we all have experienced some form of condensation, it’s worth remembering that you can get condensation on the outside of your windows too, and just like condensation within your home, this can form on some windows and not others, even if they are right next to one and other. This doesn’t mean anything is wrong with your windows or that they have been fitted in-correctly. Condensation on the outside of your windows is a natural thing and can be ignored.


Condensation factors and how to address them

There are three factors that can affect condensation:  water vapour content, inside room temperature and outside temperature. We have posted a blog on this not too long ago, and it’s well worth reading if you are suffering with condensation. You can read the post here
