Multi-layer Thermal Foil Roofing Insulation YBS SuperQuilt - 1.5m x 10m Roll
Description
SuperQuilt multifoil insulation is a 40mm thick lightweight, flexible and versatile insulation product that can perform well in roofs, walls and floors. It’s designed to reduce cold bridging and reduce heat build-up in summer months as it reflects infra-red radiation and deals with the 3 forms of energy transfer. As well as offering a high thermal resistance at the core of 1.52 m2K/W, conduction, radiation and convection are all dealt with by SuperQuilt.
Tested to EN16012, the high core thermal resistance of SuperQuilt is achieved thanks to the multiple layers and special composition of the product. NHBC accepted and meeting the requirements of both L1A and its addition L1B 2010, SuperQuilt multifoil insulation can be installed in new builds and retrofitted into refurbishment projects to improve the building envelope.
SuperQuilt has applications in roofs, walls and floors. For roofs, SuperQuilt can be used both over and under rafters as well as between and around purlins. When in accordance with good building practice and fixing instructions it can also be used as a vapour control layer if the joints are sealed with a foil tape. SuperQuilt is easy to fit into timber frames, cavity walls, dry lining and external walls as well as in suspended timber ceilings, crawl spaces and floating timbers too.
Installing SuperQuilt multifoil
This tear-resistant multifoil insulation can be easily cut with a craft knife or scissors to get to the right size. Once this has been achieved you need to be sure you have a minimum 25mm air gap on either side of the product, which can be achieved with battens.
When SuperQuilt is in place it can be fixed using 14mm stainless steel or galvanized steel staples at regular intervals. Please ensure there is a 50mm overlap and all joints are tapped with 75mm tape. SuperQuilt in most applications is applied directly from the roll, having been pulled taut and then stapled in place.

Questions & Answers
Question:
What R value does this achieve for pitched roofs?
Answer:
The thermal resistance value when applied in roofs is 2.70m²K/W.
Question:
The house is 1950s no underfelt just tiles backpointed could I fit this insulation straight to the roof spars leaving a 100mm gap behind, yes the spars are only 4x2 with some big purlins. Then counter batten and plasterboard or does it require something behind? RegardsPaul
Answer:
You'd need a breather membrane between the insulation and the roof tiles ideally, so install something like Supro first, counter batten, Superquilt, counter batten and then plasterboard.
Question:
can I cover existing insulation on the loft floor with superquilt as well as the rafters.
Answer:
You can do if you wish, but I would recommend stapling the Superquilt direct to the joists if you do, and put some foil tape over where the Superquilt overlaps the next piece etc, to help reduce thermal bridging.
Question:
Can I screw plaster board direct onto the Superquilt, or does it require battening over?
Answer:
Good afternoon to you. In order to utilize this product to its fullest potential, the manufacturers do recommend battening over, as that would give the Superquilt the 25mm airgap it needs to work in the correct manner, and perform at the stated Thermal Resistance Value.
