Underfloor Heating Insulation
Underfloor heating systems are popular ways to heat houses and that's why many people are starting to seriously at underfloor heating insulation. A room should be properly insulated because you will end up spending very large amounts of money if is not. Insulating the floor of your home will make it much easier and less expensive to heat the home. Floor insulation will be especially important if your room is situated above an unheated area in your home. Rooms above an unheated basement, for example, can suffer from extensive heat loss from the floor and that's why underfloor heating insulation is so useful. Installing your own underfloor heating insulation is very easy and is something that you should take some extra time to do whenever you are installing underfloor heating in your home.
Step 1 - Wooden Lathing
Assuming your floor is made with joists, you need to install wood lath strips which span the joists. This will be used to hold the insulation material in place, while still allowing the air to circulate. The gap between these strips should be approximately 12 inches. The wood lath strips can then be nailed or stapled to fix them into position. Try to keep these wooden lath strips straight, and square, where possible. Also ensure that they are perfectly level.
Step 2 - Insulation
Before you start handling the fiberglass insulation, you must wear gloves. Fiberglass can be irritating to the skin so it is important to protect yourself. This fiberglass insulation material then needs to be packed into the spaces between the joists. Ideally, you should be using insulation with a vapor barrier attached to the back, if not you will need to fit a separate vapor barrier. Be sure you do not insert the insulation in too tightly because this will make it less effective. Don't risk damaging any electrical wiring or plumbing, instead, fit the insulation material under the pipes and wires.
Step 3 - Insulating Water Pipes
If there are any hot water pipes which flow through the void under the floor, you should ensure these are correctly insulated. Try to choose a R3 insulation for areas which have harsh winters. Insulating water pipes will help to prevent any unnecessary heat losses from the water pipes.
Step 4 - Fitting the Heated Floor
Once you have finished fitting the under floor heating insulation you are then ready to continue fitting the radiant heated floor as normal. This needs to be stretched over the top of the newly fitted insulation and held down as normal. The extra insulation should make the whole system much more efficient and effective. Insulation can sometimes seem like a waste of time, but it will pay for itself. Fitting insulation under the floor should be treated like an investment because your heating bill will certainly show you the savings.
