What is Spray Foam Insulation ?

Spray foam insulation is an alternative to traditional building insulation. It’s also called spray polyurethane foam, or SPF for short. Spray foam insulation is a blend of chemicals which, when sprayed into place, expands from 30 to 100 times its size and sets to form a powerful layer of insulation.

What are the Advantages of Spray Foam Insulation for Your Floors ?

Energy efficiency. Keep your home warm in winter and cool in summer, creating an airtight shield that is complete and tidy.

Lower utility bills. Retained heat in your house greatly lowers your heating costs.

Complies with building regulations. Spray foam insulation offers high-performance insulation at a reasonable price and satisfies all existing building regulations.

Disposes of convection air. You will eliminate convection air currents by using spray foam to insulate the underside of your floor, while at the same time achieving the required ventilation level.

What are the Main Types of Floor Insulation we Offer ?

Suspended Floor Insulation

A spray foam insulation system is the ideal way to insulate the underside of suspended timber floors and thereby remove sick building syndrome. The spray foam insulation systems are added on the underside of the floorboards, fully protecting your house from draughts coming up from the gap under the floor.

Solid Floor Insulation

Essentially, solid floors, such as concrete, require insulation using a rigid insulation material such as Icynene closed-cell insulation. Under floor spray foam insulation eliminates draughts of air between floorboards. Icynene is moisture tight, as opposed to polyfoam or fibreboard insulation, meaning your house won't get wet. Insulating under floorboards could save you about £40 a year.

Floor renovations, as with other home upgrades, have to comply with your current regional building regulations. If you hired an approved consultant, they’ll do a compliance screening on your behalf, saving you the trouble of getting it done yourself.

The Icynene insulation system is a full spray foam insulation, air and moisture barrier device that seals floors, windows, walls, and ceiling cavities against air movement at baseboards, including gaps around electrical outlets and light fixtures, as well as where walls meet windows and doors.

This ensures that the ambient air (both hot and cold) cannot pass through walls, creating draughts or cold spots. It also ensures that warm indoor air cannot escape.

There are two forms of spray foam available: open-cell spray foam that typically costs £0.35 to £0.55 per board foot, and closed-cell spray foam that ranges from £0.80 to £1.20 per board foot. The estimated overall cost of professional installation of spray foam is around £2,000.

For most homeowners the installations may be completed within a day, but larger projects such as commercial installations can take longer. Our insulation surveyor will send you a clear description of the time-scales you can expect once he has evaluated your requirements.
