Question:
Are there any products to insulate the reveal of a fitted Velux window?
Answer:
Yes, there are several products designed specifically to improve insulation around the reveal of a VELUX window, whether it is already fitted or being installed from new. 1. VELUX Insulated Reveal Lining: The VELUX LSB MK04 2000 Lining including Facings is designed to provide a neat internal finish. While it doesn't provide significant insulation itself, it ensures the reveal is formed correctly for optimal airflow and thermal performance. 2. Thin PIR Insulation Boards: For an existing installation, one common solution is to fit thin PIR insulated plasterboard to the reveal before plastering. These boards offer excellent thermal performance, minimize condensation risk, and keep reveal dimensions reasonably compact. 3. Phenolic Insulation Boards: If space is limited, you could consider using phenolic insulation boards, such as Kingspan Kooltherm K12 Framing Board or Kingspan Kooltherm K118 Insulated Plasterboard. These boards provide better thermal performance than standard PIR for the same thickness, making them ideal for narrow roof window reveals. 4. Aerogel Insulation: If the reveal is already tight and you cannot lose much space, products like Spacetherm Aerogel Board or Proctor Wraptite Aerogel products can provide useful insulation in thicknesses of only 10-20mm. Please note, these are usually more expensive than PIR insulation. Regarding the reveal shape, VELUX recommends a horizontal reveal at the bottom and a vertical reveal at the top. This design improves daylight penetration and helps warm air circulate across the glass, reducing condensation.
Question:
Can Velux liner be cut to suit roof thickness..?
