Whole House Approach Is Best!

We recommend insulating the whole of your property while you are motivated for maximum savings .  Remember , your heating bills will increase year on year, so doing the Floors, loft, and walls  will give you maximum savings to your bills. Floor Insulation – Is It worth it?
A small amount of heat is lost whatever floor type you have, be it concrete or suspended wooden floor. Insulating your floors should save you around £50 per year in heat savings. Whilst it is a very small saving, it is very much worthwhile.

Should You Insulate all Floors ?

·   You don’t need to insulate the floors of upstairs rooms in your house if they’re above heated spaces, such as the living room.

Rooms above unheated garages do need to be insulated.

Rugs and carpets on the floor will also help your feet feel warmer, which might mean you don’t feel the need to put the heating on as much. 

Wooden Floors

Old suspended wooden floors can be very draughty and insulating them will save you up to £50 a year on lost heating.

These Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists. Average room will need 3-4 rolls of insulation and cost will be around £15 -£20 per roll depending on thickness.

  You can also use foam board such as Kingspan.
 Remember to seal  the Gaps and draughts around the  skirting boards and floors too  with a tube of sealant bought from any DIY store.

Air Bricks – Please note.

Wooden floors will have air bricks in your walls, so take care not to block them up. They are needed to help ventilate the space under your floor and stop your floorboards rotting. 

Concrete floors

New houses will have a ground floor made of solid concrete.
Solid floors are insulated using rigid insulation foam, which can be fitted either above or below the concrete. 
This will raise the level of the floor, so you will need to       Trim doors  down. ·         Move skirting boards and some electrical sockets.
If the concrete is above the insulation it can store heat during the day, which helps to keep the room warm at night. If the insulation is above the concrete the room will heat up more quickly in the morning.

Building Regs

You have to insulate a solid floor when it is replaced in order to comply with building regulations. The finished floor should achieve a U-value of 0.25 W/m2K or less. 

Remember…A Warm Home Is A Happy Home!
