Multi-read content how to insulate floors in an old house

Old heritage homes may be beautiful and have a high value on the housing market, but they present another dilemma for their owners: renovating them is hard work and they are expensive.

Thermal comfort is one of the most difficult aspects to improve and maintain in most heritage homes, whether it’s a Victorian, Edwardian or Queen Anne home. An older home with old and damaged fireplaces, original sash windows, drywall and towers and high ceilings with bare rosettes makes it difficult for the homeowner to transform their thermally efficient living space.

During inclement summer and winter weather, it is even more difficult to maintain a comfortable temperature because indoor air can easily be lost to the outdoors through numerous humid areas. In general, heritage homes are comfortable in the summer, due to their high ceilings and solid walls, but they are particularly cold spaces in the winter.

A complete renovation would be the easiest way to fix this problem. But altering the original design of the heritage property would mean sacrificing its historic character and authenticity, as well as potential problems with the Council and heritage groups.

The best energy-saving solutions for heritage homes

Fortunately, there are less expensive and non-invasive ways to regain thermal comfort and improve the energy efficiency of heritage homes.The old house is insulated and draft proofcan significantly reduce your carbon footprint and provide year-round levels of thermal comfort! Oh yes, a renovation can reduce your energy bill by up to 50%! Here are some specific ideas on how you can improve your home’s thermal comfort over the long term:

1. Proof draft of your door and windows.

Prevent summer and winter heat exchange by sealing doors and windows.Anti-draught for your doorviaApply Draft Dodgers. These Draft Dodgers are a set of moldings and compression gaskets mounted on the perimeter of the door to seal tightly, preventing the ingress of air. To prevent air from entering through the bottom of the door,Install Draft Exclusive.

Fill the gaps around your windowsis an economical alternative to replace your old windows.Improve the insulation of your windowsapplyingwindow scratch stripon the window frameto seal gaps and cracks, eliminating the need to replace windows (unless your panes are damaged, of course!).

let’s be strongdouble hung windows,use the draft hoodto block the air from the perimeter and the middle part of the windows.

solutions for retrofitting the home; draught proof doors and windows and install ecoGlaze

To make your windows even smarter, equip them with durable double glazing. OursecoGlaze® double glazingis a clear acrylic sheet that conforms to your window frame to trap static air between your existing windows and the ecoGlaze® acrylic sheet.

This layer of air can reduce heat transfer through your glass windows. ecoGlaze® double glazing can be easily applied to all wooden windows and some aluminum windows

2. Insulate your ceilings and floors.

Continueda layer of high polyester insulationAbove your ceiling helps contain your heating in the winter and prevents it from escaping your home. In the summer, it helps absorb heat entering your home through the attic. The same effect occurs when you add insulation under your suspended floor.

3. Draft proof of your chimney and hearth.

Chimneys and fireplaces are notorious passages for air. They are designed to exhaust air from the house without necessarily starting a fire. From herehow to avoid chimney drafts: Use a superior shock absorber. Mounted on top of the chimney, the damper swing cap seals the chimney when closed, blocking drafts.

If your heater is completely idle or intermittent, use Chimney draft plug.This is high density foam rubber that is cut to fit securely in the chimney throat connecting the hearth and chimney and is available here.  

4. Seal gaps and cracks.

Small openings appearing in random areas of your home can negatively affect your thermal comfort since outside air can seep through these spaces.How well do you close those air leaks?very important in managing your thermal comfort in both summer and winter. Look for these gaps and cracks around windows, cabinets, door perimeters, floors and vents.Use a flexible, durable, mildew-resistant, water-based sealantto fill these gaps.

Popular questions about how to insulate floors in an old house

how to insulate floors in an old house?

Use the insulation of your choosing—SPF, fiberglass batt, rigid XPS, or EPS foam—they all work well [3]. Use enough to get somewhere between R-15 and R-23 and you’ll be doing fine. If you’re using batts or rigid foam, it’s a good idea to first caulk the seams between the rim and floor joists.

How do you insulate an existing solid floor?

If you have an old solid floor made of stone flags or similar, then the best way to insulate it is to remove the flagstones, dig down and add a membrane, insulation and screed, before re-laying the stones. This is a big task, but it has the advantage of adding a damp-proof layer which probably wasn’t there before.

Is it worth insulating under floor?

Insulating your ground floor is a great way to keep your property warm. Generally speaking, you only need to insulate the ground floor. If you’re on an upper floor, you don’t usually need to insulate your floor space.

What is the best insulation under floors?

High performance insulation panels or boards are often the best materials to insulate an existing concrete slab floor as they provide the best thermal performance at any given thickness.

Can I insulate under floorboards?

You can insulate the floorboards by lifting them up and laying mineral wool which will need to be supported by netting. To provide fire resistance to the insulation, plasterboard should be fitted to the ceiling of the basement.

How do you insulate old concrete floors?

When installing insulation on top of the concrete floor, the most common method of installation is as follows. Lay the damp proof membrane onto the concrete, followed by the insulation. Then lay moisture-resistant chipboard, or a concrete screed to the top, which can then be covered by the flooring to finish.

How much heat is lost through the floor?

10 percent
More than 10 percent of an average home’s heat is lost through the floor. This percentage can be much higher in older homes with hardwood floors—or floors made of other materials that conduct heat and cold.

How do I install insulation under a floor?

What is the best way to insulate under a wooden floor?

Answer: Ideally a fibrous insulation such as mineral wool or sheep’s wool performs best between timber because it will take up thermal movement and cut down air movement around the insulation. ‘Thermal bypass’ affects performance, so cutting out draughts is preferable.

Can underfloor insulation cause problems?

What Can Go Wrong With Underfloor Insulation? Worst case scenario you trap moisture from spills or interstitial condensation up against the timbers within hydrophobic insulation and in turn risk rotting the floor joists.

What is the cheapest way to insulate a floor?

Insulate Under Floor: Fiberglass insulation batts or rolls are the most economical and easiest DIY choice for insulating between the floor joist in a crawl space. The U.S. Department of Energy recommends R-11 (3½”) insulation under floors in warm climates and an R-25 (6” to 8”) in cold climates.

Can underfloor insulation cause damp?

One thing which we have found to be the cause of very bad sub-floor condensation, which has led to serious Dry Rot attacks, is where insulation materials have been fitted underneath floor-boards.

What is the minimum thickness for floor insulation?

Building Regulations

would require at least 70 mm of high-performance foam insulation, or 150 mm of mineral wool, (although this will vary depending on floor type, construction, shape and size).

How do you insulate old hardwood floors?

Unfaced batts are often a good choice for subfloor insulation. This material creates a reliable vapor barrier, and can easily be attached with metal rods, netting, or plywood boards. Some areas under the floor are more difficult to access, such as crawlspaces or places where pipes are running overhead.

Does floor insulation need a vapor barrier?

After the insulation is in place you will want to add a vapor retarder, sometimes called a vapor barrier, if you need one. Not every wall does. A vapor retarder is a material used to prevent water vapor from diffusing into the wall, ceiling or floor during the cold winter.

In this video I’m showing you how we go about insulating under the floors in our 1920’s semi-detached house renovation. Up to 15% of a home’s heat is lost under the ground floors so it’s something we really wanted to do in our bid to make the house as thermally efficient as practically possible.

Insulating an old house is a huge challenge. There are many variables that complicate the process of adding insulation into previously empty wall cavities. Before taking this project on, do your research! The time spent on examining all the pros and cons of insulating an old house can make a dramatic impact on the longevity of the house. All the big box stores sell a wide variety of insulation. You can also find it on Amazon:

Insulation can come in many forms and thicknesses. Typical insulation is fiberglass and cellulose. There are also foam insulation boards (polyethylene) and even batts of insulation made out of old jean denim if you want to avoid the annoying itch of fiberglass insulation installation.

Insulation comes in various widths as well – r-13, r-19 etc. Some insulation is faced ( has a paper or foil side to it). Some is un-faced.

Adding the right insulation in the right way is key to a well don job. It is not simple. Rather it is quite complicated if you want to add insulation without causing damage to the old house which never had wall insulation when it was built.

The insulation in the wall cavities must always stay dry!

Our choice was to add house wrap to the exterior and reside the house. Along with doing that, we are installing all new windows and doors being sure to properly flash all the openings. This way we can make sure the the newly insulated wall cavities will stay dry. Dry insulation means a long life for the house walls.
