This is an update of my previous video describing condensation problems in lofts. Glad to say the condensation has vanished since improving the airtightness of the loft hatch surround moulding where it fixes to the ceiling panels.
In this video I want to show why it’s important to make sure the loft hatch is fully insulated. Many people make the effort to fully insulate their lofts but forget the loft hatch. New builds have fully airtight and insulated hatches but older properties often don’t. You can buy fully insulated hatches from retailers but they can cost over £100. This DIY video demonstrates that you can insulate your own loft hatch using easy to find materials that would otherwise be thrown away. In this instance I used some left-over expanded polystyrene packaging (from a bathroom sink unit) which was cut to size and hot-glued onto the plastic loft hatch. There was a small section of insulation already there but as you may have seen from the previous video it was a tiny amount and not really up to the job. If you use a hot glue gun with two heat settings use the lowest setting otherwise the hot glue will melt holes in the polystyrene. Alternatively you could use PVA, latex based glue or double sided tape instead.
Be aware, expanded polystyrene is flammable and must NOT be used near naked flames, furnaces, boilers, neither should it be used to insulate chimneys or smoke stacks, or anywhere where there’s extreme heat, sparks, hot flue gases etc. But in loft hatches it’s pretty good and a lot cheaper than using purpose made insulation. This project actually cost a few pence in glue sticks and a hour or two of my time.
