BASF Elastospray LWP (low warming potential) spray foam is a closed cell high density insulation free of ingredients that contribute to global warming due to greenhouse gas effect.
The material is suitable for almost all areas of the building envelope and delivers low thermal conductivity owing to its closed-cell structure combined with airtightness while permitting insulation without thermal bridges.
BASF Elastospray LWP delivers simple and fast installation, high compressive strength, and water vapour permeability.
In its bid to curb climate change, the European Union is aiming to drastically reduce the use of fluorinated gases (F-gases) with high global warming potential (GWP). The associated EU regulation is targeting a two-thirds cut in F-gas emissions across Europe by the year 2030.
For industry, this means substituting hydrofluorocarbons (HFCs), conventionally used as blowing agents in high density spray-foam insulations, with eco-friendlier alternatives, and BASF has been a leader in this drive.
BASF Elastospray LWP has a GWP of just one, as well as zero ozone depletion potential and is installed by trained and accredited BASF Foam Master contractors.
In times of rising energy costs and shortage of living area, loft conversions are becoming increasingly popular. Elastospray LWP 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 LWP 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 LWP 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.
As with the insulation of solid flat roofs, thermal insulation of industrial roofs is one of the traditional applications of Elastopspray LWP 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 LWP 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.
Elastospray LWP closed cell spray foam Insulation on the inside of external walls is an effective airtight insulation solution. Older buildings with listed facades or those worth preserving often have low thermal insulation which can be improved by more than 60%by internal insulation. Installation is also comparatively cost-effective because no scaffolding is required for the building and it can be applied on a room by room basis. Since the internal surface temperature of the wall is increased by approx. 2 to 4 degrees, this has a positive effect on the indoor climate.
Elastospray LP spar foam insulating material is easy to apply to the inside of the external wall using the spray foam process installed by accredited BASF contractors. After a short curing time, the insulating layer is cladded on the room side using plasterboard. Comparatively little living space is lost due to the excellent insulating performance of even a thin layer of Elastopray LWP
Agricultural buildings such as stables, barns and crop stores are exposed to major stresses. Transpiration and excretions from animals, exhaust fumes from agricultural vehicles and high levels of humidity and condensation affect the building construction, along with external weather conditions such as storms, rain, snow, hail and heat.
A potential insulation for agricultural purposes should be durable, resistant and of course cost-effective.
Elastopspray LWP spray foam caters for all possible external geometries and insulates the roof both from inside and from outside. The cured material provides effective protection from draughts and strengthens the building through the compact, jointless insulating layer.
Elastospray LWP spray foam has a positive effect on the life and value of the fabric of the building.
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 LWP.
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 LWP 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.
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 LWP 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.
