Is an air-to-water system suitable for me?2019-07-20T10:11:00+00:00

To tell if an air source heat pump is right for you, there are a few key questions to consider:

Do you have somewhere to put it?

You’ll need a place outside your home where a unit can be fitted to a wall or placed on the ground. It will need plenty of space around it to get a good flow of air. A sunny wall is ideal.

Is your home well insulated?

Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it’s essential that your home is well insulated and draught-proofed for the heating system to be most efficient.

What fuel will you be replacing?

The system will pay for itself much more quickly if it’s replacing an electricity or coal heating system. Heat pumps may not be the best option for homes using mains gas.

What type of heating system will you use?

Air source heat pumps can perform better with underfloor heating systems or warm air heating than with radiator-based systems because of the lower water temperatures required.

Is the system intended for a new development?

Combining the installation with other building work can reduce the cost of installing the system.

What is an air-to-air system?2019-07-20T10:09:06+00:00

An air-to-air system produces warm air which is circulated by fans to heat your home. They are unlikely to provide you with hot water as well.

What is an Air to Water System?2019-07-20T10:07:48+00:00

An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.

What is Masonry Crème?2019-06-26T21:15:00+00:00

Masonry Crème is an invisible insulation barrier.

A surface treated with ProPERLA Masonry Crème will insulate mineral building materials by reducing water absorption. The product chemically bonds to the surface, penetrating up to 17mm to create an invisible insulation barrier.

What does super hydrophobic mean?2019-06-26T10:38:16+00:00

It means water cannot stick to the coated surface but forms droplets that run off the surface.

Tests have shown that a damp content of 5% in a plain brick wall, for example, can lower the insulation performance by up to 50%, especially where cavity wall insulation has been installed. Porous building materials, such as natural stone and brick normally have good insulating properties as they have air filled cavities, which offer low thermal conductivity, but only when they are dry.

Is Icynene suitable for new builds?2019-08-09T14:56:46+00:00

Icynene foam is well-suited for insulating walls and roofs in new buildings; it provides a high standard of thermal insulation, minimises air leakage and reduces the transmission of contaminants from outside, as well as reducing nuisance noise. Icynene foam forms a permanent, seal to studs, flexing and moving with the rest of the construction, so improving the long-term airtightness of the building and reducing energy use.

Timber or steel frame walls may be insulated by spraying Icynene foam between the studs, to their full depth, while walls of portal frame builds may be insulated by filling the cavities between the internal and external faces with Icynene foam.

Roofs may be insulated by spraying to the underside of the deck (flat roofs), timber sarking, or to the underside of the roofing membrane. Because Icynene foam expands when sprayed it is easy to form a continuous layer of insulation even across challenging roof shapes.

Icynene may also be sprayed to the underside of metal roof decks to minimise rain noise.

Can Icynene be used for wall refurbishments?2019-08-09T09:32:45+00:00

Icynene can be used to upgrade existing masonry walls by internally insulating them. The internal face should be battened out to the required depth with battens at 600mm centres. Icynene is then sprayed to the depth of the battens and trimmed. The wall is then finished with plasterboard.

As insulating the inner face will change the temperature profile through the wall, condensation risk analysis should be carried out to determine whether a vapour control layer (VCL) will be required.

System built walls, such as Trusteel, can be insulated with Icynene LD-P-50 in the wall cavity. Similarly, cavities behind lath and plaster on solid stone walls can also be insulated with Icynene LD-P-50.

What about floor refurbishment?2019-06-26T10:17:37+00:00

Suspended timber floors suffer from heat loss by conduction to the underfloor void, while sub-floor ventilation to prevent damp results in draughts between the boards and at the floor perimeter.

Icynene foam can be sprayed to the underside of the boards, filling the space between the joists. The insulation will reduce conduction heat loss through the floor – making it warmer underfoot – and also eliminate air infiltration through the deck and the perimeter.

The installation should leave a minimum 150mm air gap between the underside of the joists and the surface of the sub- floor void. High-rated electrical cables (such as cooker or shower supplies) should be de-rated or set in trunking or conduit to avoid overheating.

Is Icynene suitable for roofing projects?2019-06-26T10:21:02+00:00

Icynene foam can be sprayed on the underside of tiles and slates and timber sarking to upgrade the thermal performance of existing pitched roofs (figure 06). The loft may be insulated in order to improve the overall thermal performance of the dwelling, or to provide additional living space. Where a low U- value is required it may be necessary to fix cross battens to the underside of the rafters to increase the depth of Icynene foam.

The gable walls should also be insulated with Icynene spray foam to form a well conditioned space. If the loft is going to be used as an occupied space the Icynene foam must be protected with a fire-resistant covering such as 12.5mm plasterboard.

Icynene foam may be sprayed onto the underside of a vapour open roofing underlay. The foam maintains the drape of the underlay, allowing wind-driven rain to drain from the batten space without the need for counter battens.

Where the roofing underlay has a high vapour resistance (being either bituminous felt or polyethylene) condensation risk analysis must be carried out to test for a risk of interstitial condensation. Where there is a risk of condensation a vapour control layer should be installed to the underside of the roof, immediately above.

Single or twin-skin metal sheet roofs may also be upgraded with Icynene foam to reduce air leakage, minimise sound transmission and avoid condensation forming on the underside of the roof.
