While the weather for many of us is still quite mild, it is a good time to get up in your loft and insulate. You can lose up to 15% of your heating through your roof if you don’t have insulation, and this can equate to a loss of up to £155 a year!

Top tips on loft insulation:
Clear all rubbish and clutter out of the loft.
To stand in the loft use a length of board about 25mm thick and at least 1.3m long, to lay across at least 3 joists. The ceiling joists themselves are not meant to be stood on as they are not load bearing and the gaps in between the joists are 12mm plasterboard which will not support the li8ghtest of humans!
Use a proprietary lead lamp to provide adequate lighting in your loft.
It is very important that your loft is ventilated. Poor ventilation leads to condensation forming in the loft and this condensation can soon rot roof timbers and cause structural damage. If there are no roof windows then follow the loft floor along to the point where the roof comes down to meet it. At this point (called the eaves) there should be a gap between the underside of the roof and the outside wall. This gap should be about 25mm wide and will usually have a meshed grill within it stopping insects and birds getting into the loft. Any cracks or holes in the ceiling should be filled before laying your covering.
All wiring in the loft must be lifted and laid on top of the insulation otherwise the cables will overheat and become a fire hazard.
See our project on loft insulation and how to fit it for more information.

We live in a very old cottage in Scotland. There was little or no insulation.
I need to insulate between the ceiling rafters in the bedroom. There are also furry guests scuttling about that I need to evict. I can’t access the space from the first floor above because the floorboards are very securely fixed and partially extend beyond my reach.
I need to pull down (some?) of the plasterboard ceiling to insulate. Do I need to pull the whole ceiling down to fit a Waterproof membrane? This old cottage is well ventilated (!) & we have no central heating.
Any help would be appreciated

We’re converting our garage into a kitchen ourselves. Its a solid 1930′s building with a reasonably good concrete slab floor. I’ve heard I can put insulation on top and then screed and tile – anyone got any knowledge of this method? Thanks.

Welcome on board MGC Ltd and a unique product called Septatap Thermal. Sempatap comes in rolls, just like wallpaper, and just like wallpaper, it is stuck to the wall.
The effect of Sempatap thermal can be seen quite clearly below. Heat loss is shown in Yellows, oranges and reds and before Sempatap installation money is just pouring out of the walls.

Heat loss from houses is dramatic
Only 10mm thick, it offers huge energy savings and heat loss is reduced considerable especially in the millions of older properties without double glazing and cavity walls. Its easy to install, can be decorated just like the original wall and even tiles can be laid on it.
There are discounts available in certain parts of the country as part of the Governments commitment to reducing energy loss in the UK.
Sempafloor is a special version to stop heat loss through floors and both the floor and wall version have great sound reduction qualities.
