Can I install downlighters in conjunction with Recticel Insulation boards?
The temperature of a lamp can reach 2000C. Without adequate ventilation to allow the escape of heat, downlighters can cause fires. Recticel recommends the following measures are taken when installing downlighters: Downlighters should not be recessed into insulated ceilings if they penetrate the vapour control layer (VCL). This will result in them drawing warm moist air into the roof space where it could condense and drip back out of the fitting, causing a potential fire risk. Where downlighters are to be used they should be fitted into a false ceiling below the structural ceiling. Overheating can occur where thermal insulation is laid over existing downlighters and any associated transformers that are not designed to operate under these conditions. Cables and other electrical equipment should not be covered by insulation. In all cases, the downlighter manufacturer's instructions should be followed. They should specify the amount of space to be left around the back of the fitting, its fire rating, whether it can be covered with insulation, and the type/wattage of suitable lamps. If in doubt, consult a qualified electrician.
How should I store Recticel Insulation boards?
Our boards are supplied in polythene shrink wrap which is designed for short-term protection only. It is accepted that storing boards indoors is not always possible – when outdoor storage is necessary, boards should be stored clear of the ground, on a level surface, and under cover to protect them from prolonged exposure to moisture or mechanical damage.

Is Eurothane PL available with a vapour control layer?
Recticel Insulation's Eurothane® PL is a versatile product that can be fixed either mechanically or with gypsum adhesive, in accordance with installation guidelines. It has a built-in vapour control layer as standard, located between the PIR core and the plasterboard.
What is the best way of achieving an air and vapour barrier when using Recticel PIR insulation panels?
As per the literature supplied with the product - an effective air and vapour barrier can be achieved by the taping of board joints using suitable insulation tape, the inclusion of a separate proprietary vapour control layer or the use of a foil backed plasterboard all of these methods are acceptable forms of air/vapour control.
What is the minimum working temperature for installing Recticel Insulation boards?
Recticel Insulation products should not be installed on site when the temperature is below 5°C. Below this, condensation may form.
