Loft Insulation Board

Save money on your energy bills and reduce your carbon footprint with our loft insulation boards. We have an impressive range of loft insulation board options from Celotex, Kingspan, Warmline, Quinntherm, and many more top brands. The range includes different types of boards, including thermal bridging board, pitched roof board, and insulated plasterboard. 

Our loft insulation boards are available in a range of thicknesses (20mm to 200mm) and most boards will cover an area of 2.88m² each so you will be able to find the appropriate board for your project on our site. 

Thermal bridging board is used to reduce the amount of heat entering or leaving the home through studs and other building components that will conduct heat in an undesirable way. Pitched roof boards (like Kingspan Thermapitch TP10) have been designed for those trying to create a warm loft, by insulating both ventilated and unventilated roofs. For those looking to combine a couple of jobs, Celotex’s insulated plasterboard might be the way to go, as you can easily put up this joint product, leaving you more time for other tasks.

Efficient loft insulation is a linchpin in creating energy-efficient homes, minimising heat loss, and subsequently reducing energy bills. At insulation4less, the array of Loft Insulation Boards delivers varied solutions for diverse insulation needs. Explore through an assortment of insulating boards optimised for loft spaces, emanating from reputable vendors like Celotex, Mannok, Danosa, Kingspan, Warmline, Recticel, Thermboard, and Unilin.

 

General Purpose Insulation Boards

Celotex GA4000 & TB4000 and Recticel Eurothane GP

A versatile range of insulation boards that are suitable for numerous applications, including roof, wall, and floor insulation. These PIR boards, owing to their remarkable thermal performance, find varied applications across different loft insulation requirements. Whether your objective is to prevent heat loss through roofs or walls, these general-purpose boards furnish robust, reliable insulation.

 

Insulated Plasterboards

Celotex PL4000, Warmline PIR, EPS, & PHE

Imbued with the dual functionality of providing insulation and a plasterboard surface in a single product, insulated plasterboards facilitate effortless installations and an additional layer of insulation to lofts where internal linings are present. Particularly apt for refurbishments or new builds where internal loft linings can integrate an additional insulating layer, these products amalgamate thermal efficiency with practical usability.

 

High Thickness Insulation Boards

Celotex XR4000 & Unilin Thin-R PIR

When maximum thermal performance with minimised board thickness is imperative, these insulation boards stand out. Particularly well-suited for lofts with space constraints yet requiring optimal thermal resistance, these boards exhibit compelling insulating properties with notable R-values, ensuring your loft remains warm while preserving valuable space.

 

XPS Insulation Boards

Danosa Danopren TR & Warmline XPS

XPS (Extruded Polystyrene) insulation boards, notable for their exceptional moisture resistance, are a supreme choice for lofts prone to moisture or where high levels of thermal efficiency are necessitated. With their characteristic blue and pink hues, XPS boards deliver steadfast, long-term thermal performance and durability, safeguarding your loft against thermal bridges and potential moisture ingress.

 

Pitched Roof Insulation Board

Kingspan Thermapitch TP10

Specially designed for insulating pitched roofs, Kingspan Thermapitch TP10 is your go-to option for ensuring optimal thermal performance in loft spaces beneath the roof. This product is formulated to deliver high thermal resistance, ensuring that heat is conserved within the living space, optimising energy utilisation and providing a comfortable indoor environment throughout the various seasons.

 

Loft Deck Insulation Board

Thermboard Insulated Loft Deck Board

Crafted for simplicity in insulation and boarding your loft space in a singular solution, Thermboard furnishes an all-in-one loft deck insulation solution. With the capability to lay down an insulating layer while providing a robust platform for storage or access, Thermboard allows you to insulate and utilise your loft space efficiently without compromising on thermal performance.

 

 

Choosing the Right Loft Insulation Board

Selecting the perfect insulation board hinges on a myriad of factors including the type of loft, existing insulation (if any), desired thermal performance, and budget constraints. General-purpose PIR boards like Celotex GA4000 offer multi-faceted applications, whereas specialised products like Kingspan Thermapitch TP10 and Thermboard provide optimised solutions for specific loft types and usage scenarios.

Ensure to consider:

Thermal Performance: Assessed via the R-value or U-value.

Space Availability: Determine thickness based on available loft space.

Moisture Resistance: Especially relevant for damp-prone lofts.

Budget: Evaluate cost-effectiveness vs. thermal performance.

Usability: Factor in whether the loft will be used for storage or living space.
