Pitched roof insulation

In times of rising energy costs and shortage of living area, loft conversions are becoming increasingly popular. Elastospray 1629 can be applied from inside the loft space without the need for re-roofing, adding another room to the house, cost effectively.

Since the rafters of existing homes are normally only 10 to 20 cm thick, the thickness of insulation with conventional material between the rafters is often not enough to meet today’s thermal insulation requirements. Elastospray 1629 extremely low thermal conductivity and high insulating performance with a low thickness, means there is no need to extend the depth of rafters which is costly in terms of both time and money. Using the proven spray foam process, Elastospray 1629 is simply sprayed between the timber rafters without the need for laborious cutting and fitting. This produces a solid, air tight foam layer, with a high thermal insulation effect without energy wasting joints that occur when normal insulation materials are laid.

External roof insulation

As with the insulation of solid flat roofs, thermal insulation of industrial roofs is one of the traditional applications of Elastopspray 1629 spray insulation. Roofs of warehouses, production facilities, exhibition and sports halls are normally made of profiled metal sheet and have relatively large spans. These lightweight roof constructions require a lightweight insulating material to be able to take the additional loads produced by snow, wind and rain.

Because of its in-situ installation properties, Elastospray 1926 spray foam can be applied to the metal sheet profile seamlessly, coating both the peaks and troughs in the profile. The insulating layer then only needs to be provided with UV protection. Vapour barriers, sloping screeds or other additional materials are not normally needed, saving valuable time and money.

Internal wall insulation

As with the insulation of solid flat roofs, thermal insulation of industrial roofs is one of the traditional applications of Elastopspray 1629 spray insulation. Roofs of warehouses, production facilities, exhibition and sports halls are normally made of profiled metal sheet and have relatively large spans. These lightweight roof constructions require a lightweight insulating material to be able to take the additional loads produced by snow, wind and rain.

Timber wall insulation

Timber frame construction is typical in Great Britain and Ireland. As the name suggests, this method of construction relies on a timber frame as a basic means of structural support. The outer leaf is typically stone, brick, render or timber, to suit the local district or planning requirements.

Elastospray 1629 is applied between the studwork of the timber frame for thermal insulation. The low thermal conductivity of the material has clear advantages here because despite low wall thicknesses, a comparatively high insulating performance is achieved. The cured spray foam guarantees additional support and stability for the whole of the timber frame construction. The “in-situ” application of the foam also guarantees air tightness of the structure, something traditional insulation methods cannot do. There must be an air gap between the external facing and the insulated timber frame for ventilation.

Soffit insulation

Cold ground floors of a building occur if the soffit is not insulated against the unheated basement. The low temperatures in the concrete soffit can lead to high energy losses, interstitial condensation and even the formation of mould. This problem can easily be resolved by insulating with Elastospray 1629.

The BASF spray foam system can be applied to most soffits, without costly access equipment. The material is self-adhesive and requires no labour-intensive cutting and fixing. Water pipes and electrical cables can easily be hung beneath the insulation. Any uneven areas such as old vaulted basements, ribbed or waffled shaped soffits, can be rapidly and economically insulated using Elastospray 1629 spray foam.  The insulation is seamless compared to conventional insulating methods, so there is no risk of cold air penetrating through the ceiling and creating heat loss.
