Why spray foam insulation?

Underfloor insulation is one of the most overlooked aspects of insulation in old buildings yet it can be one of the most cost-effective solutions to making a warm draught free home.

Energy savings from floor insulation not only apply to heat loss, but a major part is also stopping draughts that allow cold air to trickle into a property, expansion gaps under skirting boards on the building perimeter allow cold draughts to push into the building envelope which results in pushing warm air upwards making it cold and draughty at a low level.

Our spray foam solution eradicates these draughts and eliminates cold floors, open-cell spray foam stays soft and flexible and will fill expansion gaps and other voids left by pipes and cables, With its ability to flex it still allows the building to expand and contract with seasonal changes without losing its air seal.

Underfloor insulation suspended floor

Using wool or fibre type materials can give some benefit but as these products are not classed as air barrier materials they still allow cold air to circulate through the material and allow draughts to penetrate the building envelope, Open-cell spray foam insulation gains air barrier status at 2” thick yet remains breathable allowing all materials to continue to breathe naturally without trapping moisture or causing sweating of timbers, people often ask how can it be airtight and breathable. Breathability is the measure of moisture movement via diffusion and not the ability to stop air movement.

A high percentage of houses in the UK have suspended timber flooring on the ground floor, and unless the void between the base of the property and the floor is properly insulated, draughts will circulate causing the floor to feel cold to touch and will also contribute to energy wastage.

If your property suffers from any of these issues you'll benefit from Underfloor insulation:

How does underfloor insulation work?

HBS Spray Foam is the superior underfloor insulation solution. When applied, the foam expands to 100 times its original size, completely covering the most complex of structures with ease, expanding into every gap or void that is present. As a result, when it solidifies it forms an airtight seal, preventing any draughts from penetrating the property, and has high thermal resistance; as heat rises, the main objective in underfloor insulation is to prevent cold air from rising up through the floor and pushing the warm air in the property into the loft.

It fully adheres to a surface when applied; no netting or other form of the fixing is needed to keep it in position, and it does not degrade or sag over time – making it ideal for use on the underside of a suspended floor.

HBS Spray Foam will work at its full potential for the life of the building, and all installs are automatically covered by a manufacturer’s 25-year warranty policy when installed by Green Horizon Energy Solutions. Icynene is also the only foam on the market to have achieved BBA, BDA, ETA and IAB certification, giving you total peace of mind with regards to the integrity of the product.

Access for underfloor insulation

Once we have a suitable access point we physically send a person underneath to apply the insulation directly to the underside of the boards, in some instances we can work with a gap of just 50cm so if you are in doubt to if we could fit underneath you would be surprised at some of the tight spaces we work in, we will always offer a free survey in order to assess the depth and ability to apply the foam because HBS LDC-50 Is an open-cell foam even when it sets (in a as little as 5 seconds) it remains soft and flexible with the consistency of a sponge.

The benefit to this is that the foam will move with seasonal changes to the buildings envelope so as expansion and contraction occur during winter and summer the foam will maintain a full air seal making sure no air leaks develop in and around the material, also as an open-cell product it will allow any bulk water to drain through without absorbing excessive amounts and will always dry out to its original state.

This is important when insulating the floor because if you had a spillage or leak above the floor you are safe in the knowledge it will not get soaked up by the insulation rather it will drain through and the small amount of moisture in the product can fully dry out through the open cells and return to its original condition without effecting thermal resistance or the air seal.

HBS open-cell acts like a windproof jacket allowing the body to breathe but stopping penetrating air infiltrating the rooms above.

What about other services under your floor?

Most floor joists are roughly 200mm deep and as we aim to apply the foam to 100mm deep. It does not interfere with electrics or plumbing pipes that are fastened to the bottom of the floor joists it will only interact with cables and pipes as they pass up to the room above.

However, there are no corrosive chemicals in the product so where it does interact it will not damage or corrode electric cables or plumbing pipes, Icynene also meets all required fire regulations as part of the BBA and BDA certificate and will not add any further fire risk, the product also requires 22% Oxygen to burn so will not sustain a fire on its own without a source burning it would self extinguish also with the end product made of 99% air there is in fact very little mass to burn.

Most underfloor insulation can be completed within a day and with minimal disruption. If you are unsure as to whether your property is suitable for underfloor insulation or if you would like further information we offer a free, no-obligation home survey service with a relaxed no pressure attitude, please feel free to call us to discuss your requirements and learn how installing Icynene open-cell insulation will help you not only save on heating cost but create a more comfortable environment.

Spray Foam Insulation FAQ's

Cost Saving

Due to the nature of HBS products, the foam, once applied, creates an air seal within a property, helping to prevent heat loss. This will reduce the amount of heat needed to fill the building, in turn saving money year after year.

Lower Carbon Footprint

As HBS helps to reduce heat loss from a property, much less energy is needed to help keep a comfortable temperature throughout, thereby reducing a property’s carbon footprint on the environment.

No Draughts

Air leakage can be responsible for up to half of a property’s energy loss. The air seal created by applying Icynene to the internal structure of a building means no gaps exist from which a draft can appear; this helps maintain a more consistent internal temperature, minimises heat loss and reduces waste, creating an efficient and comfortable living or working space.
