Polyspray
Sprayed rigid P.U. (Polyurethane) & P.I.R. (Polyisocynurate) foams have long been acknowledged as among the best insulants available.
In addition, the foams have excellent adhesive properties, which coupled with the fact that they can be spray applied, make them an ideal product for numerous applications.
Modern Plan Insulations Polyspray is available in a range of physical properties; typical densities are from 30-60 kg/m3 but others are available.
All systems are CFC free and have K factors of 0.024 w/m.
Internal grades of Polyspray have Class 1 fire rating to BS476 pt. 7 and can be overcoated with protective coatings to give Class 0 to BS476 pt. 6. Alternative coatings are available for decorative purposes, or to act as vapour retarders/barriers.
External roofing grades are available at high densities to withstand foot traffic and when coated with a suitable protective coating such as GE (General Electric) silicone rubber and have EXT, FAA & SAA fire ratings.
Polyspray can be applied to any thickness to achieve desired 'U' values and adheres tenaciously to virtually any substrate. Once applied, the Polyspray is basically inert and will, when protected correctly, last indefinitely.
Typical variants are:-
- A) Polyspray System (1) Class 1 fire rated 32 kg/m3 density rigid P.I.R. spray foam, applied to the underside of roofs for insulation, will also bond slates and tiles permanently in position.
- B) Polyspray System (2) uses the same foam system as above, but overcoated with Sprayed intumescent coating to upgrade the fire rating to Class '0'. Applied upside down to concrete in underground car-parks.
- C) Polyspray System (3) as system 1 but overcoated with spray applied vapour barrier coating in high humidity applications to prevent vapour drive and interstitial condensation. Applied in swimming pool halls, laundries, textile factories to insulate and prevent condensation.
- D) Polyspray System (4) High density 48 kg/m3 rigid P.U. system applied to the outside of flat or pitched roofs and overcoated with elastomeric weathercoating to provide an insulated weatherproofing system and achieve FAA & SAA fire rating. Applied to flat B.U.R. roofs, pitched slated roofs, corrugated fibre cement & metal sheeted roofs, to weatherproof and upgrade insulation.
cavity reinforcing foam
Isofoam CRF is a rigid Polyurethane Foam, formulated for injection into cavity walls. When injected, the foam is fluid, but quickly expands and hardens to completely fill the entire void within the cavity. Because the cavity is completely filled, the wall is stabilised over its entire area.
Adhesive bond strength is in excess of 60KN/m2. In addition, the wall is insulated to a very high level, a 65mm cavity, once filled, can achieve 'U' values less than 0.28w/m2/°C.
The materials and application are covered by BBA certificate No. 96/3286. This certificate was first granted in 1986 and has been in force continually since.
Full scale independent tests have been carried out to BS4370 parts 1-4 1988, copies available on request.
Modern Plan Insulations have carried out major contracts for numerous Local Authorities, including Milton Keynes, Watford, G.M.C., Bolton, Barnsley, Nottingham, Exeter & Liverpool H.A.T..
The system is guaranteed for 20 years.
marine & buoyancy
Modern Plan Insulations can offer a range of sprayed and injected rigid P.U. foam systems for Marine Insulation and Buoyancy applications.
Spray Grades - with Class 1 to BS 476 Part 7 fire ratings, are used to insulate hulls to prevent condensation. The system, once applied is seamless and monolithic with no joints for cold bridging to occur.
Typically, the hull is fitted with battens for final fixing of linings and the foam is sprayed between the battens. Any thickness can be applied depending on the insulation level required.
Injection Grades - with Lloyds Register type approval and Marine Safety Agency Certification, are available for buoyancy applications, where the high closed cell content, low absorption and a buoyancy of 60lb/ft3 or 958 kg/m3 are advantageous.
Specific data sheets on the various foam formulations are available on request.
condensation control
Combinations of Polyspray and either Vapour Barrier coatings or Breather Coatings can be used to eliminate condensation.
Modern Plan Insulations have successfully cured condensation problems for many clients from Swimming Pools for Local Authorities & Education Authorities to Textile Manufacturing factories, or more ordinary applications such as Computer Rooms & Football Stadium's.
Using our Computer Software, we can design a system to beat condensation. Condensation risk analysis & 'U' value calculations in accordance with BS 5250 are available, all we need is your existing construction and internal temperatures and humidity and we will do the rest.
Once applied, the system is seamless and monolithic and can be used to convert roofs into 'warm construction' with no gaps or joints to act as cold bridges.
Past clients include Parkland Manufacturing, W.J. Whitehead, Parcel Force, Oldham MBC, Silcoates Grammar School, Royal Insurance, Nat West Bank.protective coatings
Modern Plan Insulations have close working relationships and are approved applicators for most of the best protective coating manufacturers.
We can design systems for most applications using the best coating for the application rather than 'making do'.
Coatings available include:
- Decorative coatings for use over sprayed foams.
- Vapour retardant or 'breather' coatings as required.
- High performance elastomeric weathercoatings.
- Class '0' fire rated intumescent coatings.
- General Electric silicone rubber coatings.
- Very high performance sprayed P.U. & P. Urea elastomer coatings with high chemical resistance and high abrasion resistance.
Clear coatings for Filon & Glass rooflights.
If you have an application requiring a protective coating, please contact us to discuss the requirements and we will be pleased to advise on the best coating for your application.
acoustic fibre
Modern Plan Insulations are approved installers of the Monoglass and Thermoacoustic sprayed glass fibre systems. These systems comprise of an inorganic and non-combustible white glass fibre and polymer binder. It can be applied to virtually any substrate as a thermal and acoustic insulation in wall, ceiling and soffit application.
The systems are made from approximately 37% recycled glass, are "Green Spec" approved and also non-toxic and odourless. They are naturally white for light reflectance, but can be tinted if required. (Picture shows a sound studio in progress where the product has been tinted grey)
As well as being non-flammable, the system contains no cellulose or asbestos, and the polymer binder is water-based and non-hazardous. It is resistant to mould and fungal growth, adheres well to most substrates and resists air erosion.
Acoustic properties are excellent with a sound absorption and noise reduction coefficient of 0.95 at 50mm thick. Thermal properties are also good with K factor of of 0.036 w/m.
A full list of physical properties and approvals is available on request.
pirthane 'o'
Pirthane '0' is a Class 0 fire rated foam and coating composite. Pirthane has excellent thermal insulation and fire resistant properties. The system comprises of a low thermal conductivity, spray applied, insulating foam, overcoated with a water-based intumescent coating.
Uses
Pirthane '0' is used for internal thermal insulation and condensation control, typical applications are to the underside of concrete soffits or floor slabs, such as car park soffits with accommodation above, the interior of commercial buildings applied to the underside of sheeted roofs & sidings, internal surfaces of boats and yachts.
Benefits
- Low thermal conductivity
- Light weight
- Excellent adhesive properties to all substrates
- Able to withstand wind suction, vibration etc.
- Washable
- Closed cell properties mean Pirthane will resist water absorption.
