Why Choose Foam Insulation

Polyurethane spray foam, saving energy and costs, is the basis of the Webtherm System, supplied and installed by UK leaders: Websters Insulation Ltd. Spray foam insulation is one of the most versatile and thermally efficient forms of insulation available on the market today.

As the name suggests it is a foam-like insulation, which is applied in a liquid form, and then expands, setting into a rigid foam state. It can be applied to virtually any building or structure that requires insulation, such as (commercially) factories, sports stadiums, warehouses, shops, industrial units, theatrical mouldings and entertainment settings and set pieces (domestic) houses (especially roofs, under tile / slate), barn conversions, agricultural stores, cold stores, (Marine and road going) vehicle bodies and all kinds of boats and barges etc.

This includes awkward shapes such as curves, voids and containers. It is suitable for all purposes such as industrial, commercial (including concrete insulation), agricultural, domestic and marine applications. It can also weatherproof, stabilise, insulate and extend the life of many buildings.

The benefits of spray foam insulation are manifold. Some of these relate to the fact that the spray foam insulation is applied in liquid form, and so creates a continuous membrane. It means that it can exclude draughts altogether as the spray foam insulation reaches into all of the difficult corners, normally missed by other types of insulation, such as unwieldy panels.

Another key benefit of spray foam insulation lies in its sheer thermal efficiency, that is to say, its ‘u’ value (insulation value) is significantly better than that offered by alternative materials. This means that a lower thickness of spray foam insulation is required, compared to other insulating materials, therefore not encroaching into the space within in the building. For example, current building regulations decree that the required ‘u’ value for a living space in a roof needs to be 0.16. To achieve this, 100mm /4inches of foam is used.

By contrast, to achieve an equivalent thermal value with Rockwool for instance, nearly three times the thickness of spray foam insulation, i.e.: 250-280mm or 10/11 inches would be required! Spray foam insulation, can be applied in a range of different thicknesses by Websters’ specially trained engineers. This will achieve different levels of insulation value, and caters for various budgets.

Further advantages of spray foam insulation / Webtherm are that it reduces fuel costs, which is a crucial contemporary concern, given current energy crises, climate change concerns and rising costs. It was recognised that thermal insulation can play a key role in the cost effective reduction of carbon dioxide emissions in Europe and save up to 350 MILLION TONNES per annum by 2010.

It also eradicates condensation, reduces extremities of temperatures, can have a sound deadening effect, is long lasting, is suitable for old and new buildings, preserves appearances, non-allergenic, and can be installed and therefore ‘working’ very quickly. Spray foam insulation may also be painted or plastered over, using a special resin based plaster where a fine finish is required.

All materials comply with current fire regulations, i.e. BS476 part 7 class 1. Furthermore, additional class ‘0’ (non-combustible) spray foam insulation materials and coatings are also available where extra fire protection is essential.

Without insulation a normal roof is a poor barrier against heat loss and so creates unnecessarily high fuel costs and leaves plumbing unprotected against frost damage.

Comparison Of Insulation Products

As highlighted in the above table, no other insulation material comes close when you compare thickness against the insulation value. The lower the ‘U-Value’, the better the insulation.
